A Quantum Kaddish? What fungal networks teach us about grief, God and death

0
Zara Nur confronts their own mortality, and God?, as they contemplate the fungal networks and neural entanglements lurking or waiting for us in the quantum world

Can Zara speak with their recently departed mother through fungal networks?

In April my mom passed away and I attended her funeral as a relative outsider in her life. Seeking some distance from her friends, I borrowed the Israeli custom of wearing sunglasses to her funeral despite being in the oft-cloudy Upper Peninsula of Michigan. It felt like I needed a reason to be there, so I brought my phone and videoed her funeral for my as-yet non-existant children who will never meet her. Doubtless her funeral wasn’t something I’d have been invited to while she was living, yet death is both a final estrangement and reunion. Due to our relationship in life, my mom’s passing was more relief and closure for me than it was grief.

Grieving Disconnection

In life my mom’s absence brought peace and a feeling of security, albeit with dread anticipation of her presence. Her presence brought chaos, instability, and unpredictability along an inevitable gradient to emotional abuse. Yet her absence and presence mutually denied me one thing: a parent capable of and committed to being a parent. No one else ever met the version of her that I knew, so totally different was her attitude towards other people.

As I grew up, I grew up without really ever seeing my home as a home. Not only uprooted, also disconnected from everyone and everything, especially my own Jewish family and heritage. Naturally this led to my ignorant lack of understanding and deep resentments that isolated me further. In that isolation I became kept, feeling more like a caged experiment that a mother’s child.

Finding Healing

After some terrible relationships and serious health problems, I took time to heal and grieve my upbringing. Healing is inarguably non-linear lifelong process, something our minds and bodies do, while we can intentionally practice healing deeply. That has been a painfully serious undertaking for me the past two years, though I have been on this path since 2021. And even before then I spent so much time learning embodied arts, to nourish my body, visiting both doctors and therapists. Still, the lasting sense of peace and sure knowledge of security only arrived as my mom passed.

As morbid as that might sound, the way she died was a death I’ve often feared for myself. Confronting that possibility for myself, I am grateful my mom died as she did and grateful for her teaching me something about life through her death. Looking down at her body empty of what was her, I felt an unburdening of that pain and less fear of mortality. Corpses have always haunted my mind and I’ve dreaded mortality since I was little. On some level I’ve always resonated with the idea that there is spiritual contagion in death. In Judaism, contact with dead bodies both human and other-than-human interacts with complex belief which parallel contagion.

Spiritual Contagion

While it’s true that literal disease can reside in corpses, mine was not a fear of some kind of plague. It was a fear beyond the rational in the deep ruminative spiral of my mind. Being released from that fear is the only gift my mom has given me worth carrying and cherishing. No physical gift could match the unburdening from that fear, so utterly crushing has it been.

I am also glad that she chose green burial instead of cremation or an even more ecologically impactful burial. I hope that someday the cemetary here will allow me to plant her grave with the native wild-flowers she loved, for her body to slowly entangle into over time.

Entangled Tales

I am not a physicist, yet I’ve read that heat destroys quantum entanglement, making cremation weirdly scarring, If there is a trace of what lived, even the trace of an echo, green burial grants continuity. Interestingly, another kind of entanglement persists in death, as I’ve been reading in Merlin Sheldrake’s book Entangled Life.

Fungi are often decomposers, built of ubiquituous microstructures called hyphae that combine like microscopic fibers into larger masses. Mushrooms are one such structure, yet hardly a universal strategy for fungi. Commonly hyphae weave themselves into lacy mycelial nets capable of moving nutrients and information. Fungi also love to interweave with plant roots or deeper still into plants’ own cells.

Not just plants, rather all life is within hyphae’s reach of the venerable fungi. In death fungi return our bodies to that mighty web of life, an undeniable connection to life’s cycle. In returning our bodies for our fungal friends to reunite with the Earth we enact a lasting stewardship, restful and redemptive.

Psychedelic Blessings

Judaism may have a place for fungal blessings in addition to curses, a connection I’ll explore more in anticipation of the Jewish month of Elul. As for the spiritual symptom of contagion of tzaraat often written about in the Torah, it’s as painful and destructive as any curse, yet that moldy affliction is not all fungi offer. Though Sheldrake references a folk medicine called “chamka” that is supposedly in the Talmud, psychedelics are the blessing he argues for the healing power of. While confined to being viewed with suspicion for decades, psychedelic mushrooms are now the basis of nearly-mainstream healing processes. Though Sheldrake describes some of his experiences with the eccentric Terrence McKenna, the science is serious and goes far beyond pioneering psychonauts.

Research has consistently shown that the fruits of these enigmatic lifeforms unharnesses our brains from controlling thought patterns. This in turn allows for a healing experience where one rearranges their mental connections. This rewiring often creates an experience I personally relate to being a single hypha in a vast interconnected mycelial lifeweb. It’s beyond a visceral or intellectual experience, a lasting reconnection to a sense of something universal. That experience is like a lifeline in a desert of despair, a door out of isolation, and peace with mortality.

Albeit eccentric, McKenna proposed that fungi could speak through our minds with mushrooms acting as messengers. And why not, given the complex chemical interactions that scientists have found? If hyphae carry information and people experiencing psychedelics journey through a spiritual death and rebirth, what if it’s a story of that endless cycle as witnessed by fungi? What if fungi remember through their entanglements with life and tell that story again and again inside human minds? While Sheldrake doesn’t delve deeply into the science of psychedelic experiences and understandably glosses over the details of how growing these mushrooms has become as easy as culinary oyster mushrooms, he perfectly describes this emerging field of medicine.

For many, the kind of healing one of my mom’s friends urged on me at her funeral, might be found in that same ancient fungal tale of death and rebirth. In Judaism, there’s a story about the Israelites dropping dead in their tracks and being returned to life, a story that may have a basis in psychedelic experiences more particular to Judaism. While that’s speculative, Sheldrake describes how psychedelic experiences helped McKenna and many other people through the deserts of their fears and the promise of community. That sense of connection breaks down the walls between people and helps them find connections through the substrate of their lives.

Similarly, my own experiences years ago helped me find the perspective to see my mom’s funeral as continuity, a return to universal existence. Despite wearing sunglasses and filming, I felt gratitude during her funeral instead of simply feeling disconnected. I find beauty that through slow decomposition hyphae record, retell, and remember her body’s story to pass onto roots via mycorrhizae and ever onward. I hope someday that story will ride the wind on the seeds of her beloved milkweeds, embroidered into their own story through those hyphae.

A decade ago, we met Shimrit Perkol-Finkel in a startup incubator in Tel Aviv. She was one of those unforgettable founders who combined scientific rigor with a deep sense of purpose. As a marine ecologist and co-founder of ECOncrete, she challenged the idea that seawalls, ports, and breakwaters were destroying marine ecosystems.

Her vision was to redesign concrete so that infrastructure needed around cities and harbors could protect coastlines while creating habitat for fish, oysters, and other marine life. Her invention has been installed in breakwalls all over the world from New York to Tel Aviv.

In 2021, Shimrit was killed in a tragic scooter accident in Tel Aviv. She was just 43 years old. Her death sent shockwaves through Israel’s environmental and startup communities.

But her vision did not end there.

This week, ECOncrete announced a $14 million funding round led by Builders Vision, with participation from Barclays Climate Ventures, the Prince Albert II of Monaco Foundation’s ReOcean Fund, BDT & MSD, DCP, and Open Road Impact.

Now led by co-founder and CEO Dr. Ido Sella, the company is scaling globally. ECOncrete’s biodiversity-enhancing concrete has already been used in marine infrastructure projects from Rotterdam and New York to San Diego, the Mediterranean, and New Zealand.

Over the past 18 months alone, the company has delivered more than 20 projects and created over 90,000 square meters of marine habitat.

Shimrit believed that infrastructure should heal rather than harm. We are happy to see the dream is still alive.

Desalination experts debunk Aqua Solaire, the floating desalination barge

AI makes it easy to dream, develop, and create images of what could be world-changing ideas, until the reality sets in. A new project making the rounds is Aqua Solaire, an alleged French concept for a solar-powered desalination vessel designed to bring drinking water to coastal communities facing drought, storms, and infrastructure failures.

According to project materials attributed to the Agence Française de Développement (AFD), the French Ministry for Overseas Territories, and SUEZ Water France, the vessel is designed to produce up to 500,000 liters of WHO-standard drinking water per day using 1,200 square meters of bifacial solar panels and onboard battery storage.

The ship, they posit, would anchor offshore and begin operating within hours, pumping fresh water ashore through flexible pipelines. This mobile approach could help small islands, cyclone-hit regions, and remote coastal communities that lack permanent desalination plants. The technology itself is not new.

But the package looks fresh because desalination technology usually looks like a factory with pipes, pools and pumps. But commenters on LinkedIn are going crazy over the idea, practically willing it into existence. Aqua Solaire, at least the concept of it, uses reverse osmosis membranes, the same desalination process used in some of the world’s largest water plants, including those in Israel. What is novel is the integration of solar power, battery storage, and marine mobility into one platform.

Desalination is an extremely energy-intense method for creating drinking water. And water experts like Gidon Bromberg say it should always be used as a last resort. The brine disturbs and harms sealife. Carbon emissions are catastrophic. Paired with renewables already takes some of the pressure off but it’s not a golden ticket to free water.

Israel has become the world’s proving ground for desalination. The country now gets roughly 70–80% of its household drinking water from five giant reverse osmosis plants along the Mediterranean coast, including the landmark Sorek facility, which for years was the largest seawater desalination plant on Earth.

That experience matters.

Israelis know what it takes to turn seawater into affordable drinking water at scale. They understand the energy demands, the membrane fouling, the brine disposal, and the economics. So when Israeli water professionals reacted to the widely shared Aqua Solaire concept, their comments were enthusiastic but grounded in engineering reality.

Ravid Levy, an Israeli water technology consultant with more than two decades of experience in cleantech R&D and climate resilience, put the numbers in perspective:
“500 m³/day is not a lot but could be good for small islands or coastal towns and resorts.” We are thinking about Shebara in Saudi Arabia, but they’ve already built a sedentary system on the island.

Levy’s point is important. Aqua Solaire’s claimed production of 500,000 liters per day sounds impressive, but it is tiny compared to Israel’s utility-scale desalination plants.

For comparison:

Aqua Solaire: 500 m³/day
Sorek desalination plant (Israel): ~624,000 m³/day
Ashkelon plant (Israel): ~330,000 m³/day

In other words, Aqua Solaire would produce less than one-tenth of one percent of what Israel’s largest facilities deliver each day.

Levy added another sobering observation: “We can make this capacity in a 20-foot containerized RO system. So the new thing here, and the massive size of vessel, is for the PV and batteries.”

This is perhaps the most important reality check.

The desalination component is not novel. Companies around the world, including Israeli firms, already build compact reverse osmosis systems that fit inside shipping containers and can be deployed rapidly to remote communities.

What is different is the floating solar platform?

Nir Gartzman, Co-Founder and Managing Partner of theDOCK, Israel’s maritime and water innovation hub, questioned whether the vessel exists at all: “Can you share more, company name? Vessel registration? Can’t find anything that supports such in relevant databases.”

Green Prophet searched online and unless this is in stealth mode, we can probably just boil it down to another dream of wishful thinking.

This skepticism reflects a culture shaped by necessity. Israel built its desalination industry under severe water scarcity, where technologies had to perform under real conditions, not just look good in renderings.

Despite the skepticism, Israeli experts acknowledge that the concept could fill a niche. If commercialized, Aqua Solaire could become an important tool for humanitarian response, island resilience, and water security in a warming world. Pair it to a floating bar around the beaches of Sicily and it can help brew endless pints of beer without refilling for water back on shore.

Exploring Bangkok by electric bike with teenagers

Electric bikes and cycling around Bangkok

After six or seven trips to Thailand, I thought I knew Bangkok. I’ve visited the busiest roads, like Khao San Road and its side streets. I’ve been to night markets, flower markets, malls, aquariums, and temples. I’ve taken slow boats up the Chaopraya River.

In recent years, I’ve only used Bangkok as a place to sleep before launching to Chiang Mai or for family adventures to Koh Phangan, Phuket, and other islands where life slows to the rhythm of the sea. But I had never really explored Bangkok itself with teens until now.

With two teenagers in tow and four nights to spare, we decided to give Thailand’s capital the attention it deserved. My son had one request: he wanted to rent electric bikes. A friend of his had explored Japan this way, and he was convinced Bangkok would be just as exciting.

He was right.

Getting the daily “medicine”. Well I didn’t let the kids take a shot.

After a quick search, I found Go Bangkok Tours (also known as Go Bangkok E-Bike), a highly rated small-group bike tour company run by a Dutch expat named Ray. The company is based in Bang Rak, one of Bangkok’s oldest and most fascinating neighborhoods, not far from Tower Club at Lebua, the gloriously over-the-top hotel famous for its sweeping city views and its cameo in The Hangover Part II. (Side note: I want to stay there next time.)

We booked online without prepayment, showed up with our passports, and were welcomed like old friends. The atmosphere was relaxed and personal. There was plenty of water to drink and even a coconut waiting in the fridge. This wasn’t a giant tour bus operation. It felt more like joining a local friend who happened to know every secret alleyway in Bangkok.

Is it safe to bike in Bangkok with kids?

Quiet side streets where Thai hipsters roam

This was the first question everyone asked when we returned home. “Are you crazy? How do you ride a bike in Bangkok?”

I hadn’t really thought about it because my kids ride bikes in major cities, and we know that in the busiest cities, cars get stuck in traffic and move slowly. I was mostly concerned about the pollution, and surprisingly, it was the least choking air I’d ever experienced in Bangkok.

Bangkok traffic is legendary. Motorbikes weave between cars. Tuk-tuks, which you can hail like an amusement ride, dart in every direction. Crossing the street can feel like a strategic exercise. But the tour was surprisingly safe, except when one rider ran out of power. More on that later.

Our guide was a local Thai, and the tour moved at a relaxed pace. We occasionally crossed busier roads, but most of the ride followed narrow lanes, quiet alleyways, and pedestrian-friendly pathways. Much of the time we were far from heavy traffic, weaving between the backyards and alleys of local communities.

If you’ve ever traveled with teenagers, you know the secret to a successful trip: to get them off their phones, you need to keep them moving, keep them engaged, and keep them from melting in the heat.

Bangkok in April was blisteringly hot, one of the hottest stretches of weather I’ve experienced in Thailand. The electric bikes solved everything. The pedal assist did most of the work. We still felt active, but there was almost no strain. My teens loved the sense of freedom, gliding through the city with just enough speed to feel adventurous without any real effort.

For families, this is the sweet spot between sightseeing and fun.

One caveat: your teen needs to be at least 160 cm tall.

Ebikes take you to the hidden Bangkok you’d never find in four days

The real magic was seeing parts of Bangkok we never would have discovered by taxi or train.

We passed through narrow canals and quaint neighborhoods where we saw turtles and peacocks. We pedaled through hipster cafés and street art districts, meeting Thai influencers along the way. We explored quiet Buddhist temples, stopped at the bustling flower market, visited a famous hipster coffee shop, and rode through riverside communities before returning by ferry with our bikes.

Another highlight was sampling a strong local herbal spirit nicknamed the Thai answer to Jägermeister. My teenagers were not allowed to join in, and they still haven’t forgiven me.

Feeding turtles in Bangkok

Feedling turtles

Oddly enough, the most memorable part of the day was feeding turtles.

We stopped beside a canal where there was a pond, and we were given a small bag of sausage pieces. For nearly twenty minutes, my kids and I sat together, placing the sausage on sticks and offering it to enormous turtles waiting below. They fought for our meat sticks, and we loved every minute of it.

It was simple, slightly ridiculous, and absolutely unforgettable.

A four-hour shortcut to understanding Bangkok

Looking up at every day family life on the river

Bangkok can be overwhelming. It’s enormous, hot, crowded, and not particularly walkable unless you know exactly where you’re going.

This electric bike tour gave us an insider’s introduction on day one. By the end, we understood the city better and knew which neighborhoods we wanted to revisit.

We also learned about Buddhism, temple etiquette, and the daily rhythms of life in Thailand.

Did you know that spirits in Thailand have a favorite treat?

Those little shrines outside homes, hotels, and businesses are there to attract spirits and ghosts so they don’t move in with you. And their snack of choice? Red Fanta.

If you want to make an offering, crack open a bottle and add a straw.

Don’t avoid Thailand during the rainy season

Placemarking holy trees

Warm tropical rain can be part of the adventure. Getting drenched in Bangkok while riding an electric bike sounds less like a problem and more like a story your family will tell for years.

Cost and value

There are several bike tours on offer in Bangkok. Ours cost around $50 per person, which felt very reasonable considering:

  • Four hours of guided exploration
  • Electric bike rental
  • Ferry ride
  • Snacks and drinks
  • Expert local guidance

And for the Dutch guest who ran out of power on his stand-up scooter, there was an extra battery pack fully charged and ready to go.

Near the end of the trip, there was one stretch along a busy road where our guide instructed us not to stop under any circumstances. That, of course, was exactly where his battery ran out.

For us, it was easily one of the best family activities in Bangkok.

Our verdict: 10 out of 10

We’ve done temples, beaches, jungle adventures, and countless city tours.

This electric bike tour in Bangkok stands out as one of our favorite travel experiences in Thailand.

Jailhouse Booze For Home Bootleggers

Pruno jailhouse homebrew

You don’t have to languish in jail to make Jailhouse Booze. It’s an easy, fun project you can make in your own kitchen, with fruit juice. Old-time jailbirds used to call it Pruno. We also have another, no-waste, alternative wine recipe: Pea Pod Wine.

It’s said that the merry prisoners used to save up their lunchtime fruit juice, float a slice of moldy bread on it (for yeast) and ferment it in a milk carton, or even a garbage bag. To hide it from the jailers, they’d stash it behind the toilet, and break it out at night for a soirée in the cell.

I doubt anyone makes Pruno anymore. Today’s jailers know all about it, and know where to find that milk carton or garbage bag bulging with illicit alcohol. But if you’d like to try, I recommend fermenting the juice in a clean glass or plastic jug. Stash it in a dark, cool place instead of in the bathroom.

To get that old-time feeling, keep it under the kitchen sink. Best, and most hygenically, make room in the pantry or garage for it.

Don’t make a lot. And don’t use moldy bread unless you’re willing to risk getting sick. (Or maybe inventing Penicillin.) Pruno’s pretty rough, and there’s no quality guarantee at all.

Pruno, Or Jailhouse Booze

Equipment

  • A very clean plastic or glass jug of 7- cup capacity
    A long-handled spoon
  • A funnel or large ladle
  • A latex glove or a balloon, new out of the box
    A rubber band
    A saucer to put under the container in case of fermentation overflow

Ingredients

1-2/3 cup sugar
1 quart/ 4 cups/ 500 ml. fruit juice, any kind, at room temperature
1/8 teaspoon baker’s yeast
1 small handful raisins or grapes

Dissolve the sugar in the juice, stirring well. Funnel or ladle the juice into the jug.

Add the yeast and raisins or grapes.
Fit the glove or balloon over the mouth of the container.
Tie the rubber band around the glove or balloon: fermentation will make it swell and possibly pop off the container
With a pin or needle, poke a hole in the glove or balloon. This allows fermentation gases to escape while keeping bugs and dust out.
Set the container on top of the saucer and put that bad boy away in a cool, dark place.

The Pruno will be ready when the glove or balloon deflates.
Pour it off the sediment, chill it, and enjoy.

5 projects to help kickstart your company’s sustainability journey 

Blue City Rotterdam
Blue City, smart city, renewable energy city: Rotterdam has it all if you are looking for the sustainable model

True progress happens when environmental ambition meets action. Decarbonizing efficiently is possible for any business in any sector, but actually getting started can sometimes feel daunting.  

The trick? It’s to start small and build momentum. Here are five potential projects to help you get started.  

dakpark

  1. Measure your baseline energy consumption

You can’t manage something if you don’t measure it. That’s why the first step on any sustainability journey is to get data. Start with your utility bills to establish a clear starting point. Track usage over the period of a few months to spot any patterns.  

electric bike japan
Electric cycling in Japan
  1. Create a culture around sustainability

     

It’s one thing to talk about sustainability. It’s another to embed it into the way your company operates. Get your staff involved in the journey and talk to them about why you want to reduce your environmental impact.  

Encourage a culture where people reduce, reuse, and recycle as much as possible. Provide education on the environmental impact of decisions like taking public transport to work. Run challenges to make sustainability feel fun.  

Remember, sustainability only works if the leadership team also lives and breathes its values. Encourage employees to make the most sustainable choices. Having your team use public transit instead of driving, for example, can help lower your Scope 3 emissions. Make it feel like a team effort.

  1. Switch to electric options

     

If you have a company car or a fleet, consider switching to electric vehicles. Doing so will help reduce your reliance on fossil fuels and align your business with global standards.  

Even switching one company vehicle, or providing incentives for employees to switch to electric vehicles, can help reduce your Scope 1 emissions (and your Scope 3 emissions, in some cases).

  1. Look for partners to help you out

     

Sustainability is a global effort, and it takes a team to do it well.  

If you’re a larger business that’s ready to go through bigger decarbonization projects, it might be time to look for a sustainability partner to help you build a strategy that matches your goals.  

If you’re a small business that provides services to large global corporations, reach out and ask about their Scope 3 programs. They might have initiatives that can help you decarbonize.

  1. Invest in carbon credits

     

To fully achieve net-zero emissions, many companies need to invest in carbon credits. These are tradeable assets that let companies mitigate their residual emissions by funding verified carbon projects.  

The carbon market sounds simple, but in reality, it’s quite complex. It’s important that you source your credits from independently vetted sources that adhere to the highest global quality standards.  

Start with the first step 

The most difficult part of any sustainability strategy is moving from a goal on paper to the first entry on a spreadsheet. Once you bridge the gap between ambition and your first measurable result, the momentum of success makes the next action easier.  

Hydrophilis Rebreather: After the Penis Jokes and Shark Bait Memes, Oliver Isler Says His Underwater Dream Is Serious

Hydrophilis rebreather by Oliver Isler
Hydrophilis rebreather by Oliver Isler

When Green Prophet first wrote about the experimental Hydrophilis rebreather by Swiss inventor Oliver Isler, the internet reacted exactly the way the internet reacts to unusual design.

(We have an exclusive interview on the Hydrophilis rebreather here.)

People compared the sleek underwater breathing device to a phallus. Others joked that divers wearing it would become “shark bait.” Some called it ridiculous. Others said it looked like science fiction. But underneath the mockery there was something else: curiosity. A lot of curiosity.

The original article on Hydrophilis, Isler’s radically streamlined underwater rebreather system, sparked strong reactions because the device doesn’t look like normal scuba gear. Instead of bulky tanks and hoses strapped awkwardly to the back, Hydrophilis wraps the diver into a smooth hydrodynamic shape designed to move through water more like a dolphin than a machine.

And while many commenters laughed, others were fascinated by the possibility of quieter, bubble-free diving with less drag and less physical effort. We reached out to Oliver Isler after the reaction online and asked him what he thought about the sudden attention.

We reached out to Oliver Isler after the reaction online and asked him what he thought about the sudden attention.

“Thank you for article, which explains very well the philosophy behind my prototype, designed to be as much as possible in symbiosis with its environment, moving easily with the least possible effort,” Isler tells Green Prophet.

“The greatest challenge was the miniaturization of everything that could be reduced in size, while still remaining comfortable from a breathing standpoint. I dive either on pure oxygen (0 – 6 m), with an autonomy of about 90 – 100 min., or on Nitrox 55 down to 20 m depth, with an autonomy of 45 – 50 minutes.

“I have completed 54 dives so far. My 2 mm freediving wetsuit is intended for warm water (above 18 degrees).”

Dive into the past... Palaffitic site of Preverenges Lake Léman. The pilots date from the ancient bronze (1770 - 1600 BC. J.C. ! ). These sites are UNESCO World Heritage Site. A big hat to MAURO ZURCHER for making these beautiful photos in difficult conditions. Bravo! A dive into the past... Préverenges Pile Dwelling Site, Lake Geneva. The piles date back to the Early Bronze Age (1770-1600 BC!). These sites are listed as UNESCO World Heritage Sites.

 

 

“The goal was never to make something provocative. The idea came from a dream I had more than fifteen years ago where I was swimming peacefully among whales and dolphins.”

That dream eventually became Hydrophilis, a chest-mounted closed-circuit rebreather system that attempts to rethink how humans move underwater. Instead of treating diving like hauling industrial equipment into the sea, Isler designed the system around hydrodynamics and low resistance.

“The ideal shape for minimum resistance is the NACA airfoil,” he explains, referring to the aerodynamic forms developed for aircraft engineering. “Everything was built around that principle.”

The Hydrophilis rebreather currently weighs about 10 kilograms and integrates ballast, breathing equipment, and streamlined body shaping into a single form. Unlike traditional scuba tanks worn on the back, the breathing system sits on the chest. Isler says this decision was partly made “to avoid Immersion Pulmonary Edema (IPE), a dangerous affliction whose risk is higher when inhaling from a back-mounted counterlung.”

The device is still experimental. There is no commercial model yet and no announced certification process. Isler says he has completed several dozen dives while continuing to refine buoyancy, visibility, and breathing performance underwater.

Some divers online questioned whether the design is practical. Others wondered whether the unusual shape could attract sharks.

“Suddenly I feel a little inadequate, wrote one commenter.”

But for many underwater enthusiasts, freedivers, futurists, and marine technology fans, Hydrophilis represents something refreshing: an attempt to rethink scuba from the ground up instead of endlessly refining the same tanks and hoses developed decades ago.

Traditional scuba equipment made humans capable underwater. Hydrophilis asks whether humans can become more natural in the water itself.

That difference may explain why people reacted so strongly.

“There is still work to do,” Isler says cautiously. “It’s impossible to say whether it will become a model for the future.”

Still, the project has already succeeded in doing one thing rare in the diving world: getting people to imagine a completely different relationship between the human body and the ocean.

And maybe that’s why even the critics couldn’t stop talking about it.

Green Prophet looks forward to following Hydrophilis as the technology develops and hopes to speak again with Oliver Isler in future interviews about underwater mobility, silent diving systems, and the future of human interaction with the sea.

AI data centers are triggering panic, instead of cleantech opportunities

An aerial view shows an Amazon data center last year in Ashburn, Virginia. Maryland officials are trying to balance between opponents of data centers and their environmental and energy demands, and the wholesale acceptance of centers by Virginia, for their jobs and tax revenues.

AI may unintentionally become the economic engine that finally modernizes America’s aging grid. California is experiencing a massive AI data center boom, ranking 3rd in the U.S. with 227 operating centers and 54 more in development as of April 2026, according to Stanford.

AI is triggering a new energy panic in America. Across the US states of California, Virginia, Texas, Arizona, and Georgia, residents are pushing back against the explosive growth of data centers powering artificial intelligence. People are worried about rising electricity bills, water use, backup diesel generators, massive transmission lines, and entire landscapes being transformed into server farms. They worry about the expansion and the business around it and believe that AI data centers will exploit the land, and give back little to the people in the communities.

The energy demand from AI is unlike anything the internet economy has seen before. Goldman Sachs estimates data center electricity demand could rise more than 160% by 2030. Utilities that spent years planning for flat electricity growth are suddenly scrambling to build power generation again. In places like Northern Virginia, now nicknamed “Data Center Alley,” local resistance has become fierce. Residents complain about noise, visual pollution, water consumption, and fears that ordinary households will subsidize the AI boom through higher utility costs.

But there’s another side to the story that should be getting attention instead of fear. Renewable energy projects like SunZia — the giant new wind and transmission project connecting New Mexico wind power to California — may show how the AI boom could also accelerate the renewable energy transition.

SunZia is enormous:

  • 3.5 gigawatts of wind energy
  • a 550-mile high-voltage transmission line
  • enough electricity for roughly 3 million people
  • one of the largest renewable infrastructure projects in North American history.

And it’s arriving at exactly the right moment. The question is how does it scale without becoming an out of date boondoggle like the Ivanpah solar energy project? We interviewed Moshe Luz, one of the executives and founders of the company who has ideas up for grabs.

California already produces huge amounts of daytime solar energy, but AI workloads continue around the clock. Solar fades in the evening just as electricity demand rises. So the innovation doesn’t need to come in adding more solar panels, it’s the need for better battery storage and nighttime renewables. Wind, wave, and geothermal might help.

SunZia’s New Mexico wind profile helps solve that problem because wind often strengthens later in the day and overnight. Instead of relying entirely on natural gas plants after sunset, California can increasingly balance its grid using distant wind resources combined with battery storage.

The project is already beginning to send electricity into California while final testing continues. SunZia is not alone.

Across the American West, a quiet clean-energy arms race is emerging around AI infrastructure.

In California’s Kern County, the Edwards & Sanborn project combines nearly 900 megawatts of solar with one of the world’s largest battery systems. In Nevada, the Gemini Solar project near Las Vegas pairs utility-scale solar with giant batteries designed to stabilize evening demand.

Texas has become perhaps the most radical experiment of all. Massive wind farms, sprawling solar installations, and grid-scale batteries are now increasingly handling short demand spikes that were once served by gas “peaker” plants. Texas leads America in wind energy, boasting over 30,000 MW of capacity from over 150 wind farms as of 2020, often supplying over 20% of the state’s electricity.

Meanwhile, Google and Microsoft are investing in enhanced geothermal energy projects in Nevada and Utah. Unlike solar and wind, geothermal can run 24 hours a day, making it attractive for AI-driven electricity demand that never sleeps.

Ormat’s geothermal energy providersa re leading in the world.

The bigger shift underway is that AI may unintentionally become the economic engine that finally modernizes America’s aging grid.

For decades, utilities hesitated to build large transmission systems because electricity demand grew slowly. Now AI companies, cloud providers, and electrification trends are forcing states to rethink energy infrastructure entirely.

Ironically, the same technology many fear could overheat the planet may also become one of the biggest drivers of renewable energy investment in modern history.

There are tradeoffs.

Projects like SunZia still face lawsuits from Indigenous groups who argue transmission corridors damage sacred landscapes and fragile ecosystems. It’s difficult to get ecological assessments across state lines. Renewable energy itself is now colliding with difficult questions about land use, mining prime materials, water, and who benefits from “green growth.”

 

Make Guarapo De Piña (it’s fermented pineapple juice)

Make fermented pineapple juice with barely no work at all

In Cuba, guarapo is simply freshly-pressed sugar cane juice, and is drunk on the spot, without waiting for it to ferment. But in Colombia, Venezuela, Peru and Mexico, they homebrew guarapo from pineapples or oranges, and the fragrant fluid sits on the kitchen counter top to ferment until it’s bubbly.

I learned to make guarapo de piña – pineapple homebrew – when I lived in Venezuela. It’s the most refreshing drink there is on a torrid summer day, and it has all the flavor and perfume of fresh pineapple. And it’s all natural, with a slight fizz that owes nothing to industrial additives. Venezuelan mothers used to ferment it only one day, and give it to their kids after school while it was still mild and non-alcoholic, to help them withstand the afternoon’s heat. It’s like ginger beer, but made from pineapples. Read below for the easy recipe.

Guarapo de Piña (Fermented Pineapple Juice) recipe

I like to let guarapo de piña ferment for several days and drink it as a mild tipple. But watch out. If ferments more than three or four days, it gets strong. You won’t notice it, relaxing and quaffing along…till you get up from your chair.

Traditionally, guarapo is made with papelón, aka panela or rapadura; a chunk of unrefined cane sugar. But lacking papelón, I’ve made delicious guarapo with brown sugar. The surprising part of guarapo de piña is that it’s made with the pineapple rinds, not the fruit itself. It’s a clever way to use every part of those expensive pineapples you buy as a treat, thus avoiding food waste too.

Related: make honey wine 

It couldn’t be easier to make guarapo de piña. Take a ripe, sweet-smelling pineapple, and scrub it, the rind still on, with water only. You want to get rid of any dirt, but not to destroy the natural yeast on the rind. That yeast is what will start the fermentation.

Now stand it on its flat end and slice the rind off, taking some flesh with it. You may want to cube and freeze some of the fruit to drop into the drink instead of ice cubes.

Related: Make pea pod wine

Place the rind pieces in a large bowl or jar with 2 liters (8 cups) of fresh, filtered water.

Stir a cup of brown sugar in.

Cover the jar with a clean kitchen towel. Preferably, the jar should sit in a dark corner. But covering it entirely with the towel will protect the contents from the light and keep houseflies off.

Stir the rinds and water once a day. White bubbles will form on the surface; that’s fine.

Wait 1 day for a mild drink that’s safe for kids to drink. Allow it ferment 2 to 3 days if you want an alcoholic kick to it. Taste the guarapo after 2 days and decide if it’s strong/sweet enough for you. Don’t let it go longer than 4 days, especially in the summer, or it will ferment out and become vinegar.

Strain into a pitcher and sweeten again if needed. Serve with plenty of ice. Transfer it to a clean bottle and store in the refrigerator, but drink it up over the next couple of days. And don’t close it hermetically; it will continue to ferment, even in the fridge. I found that out at dinner once when I opened a tightly-closed bottle of guarapo that fountained all over my lasagna.

Guarapo’s delicious – enjoy!

 

Meet Seramic Materials from Abu Dhabi

Seramic materials and the facade at Masdar, a zero-energy city that failed to create community but which passed tests in building standards

Seramic Materials is part of a new wave of companies rethinking what ceramics are made from and what they can do. Instead of digging raw materials out of the earth, they are using what industry throws away.

Based in Masdar City, Abu Dhabi, Seramic Materials was founded in 2019 by Dr. Nicolas Calvet and Dr. Jean-François Hoffmann, researchers working at the intersection of renewable energy and materials science. The company grew out of the Masdar Institute ecosystem and is supported by clean tech programs like The Catalyst, with early backing of around $150,000 and more than $2 million invested in research and development over time.

The Seramic Team

At its core, Seramic takes industrial waste such as steel slag, incinerator ash, and other mineral byproducts and transforms them into ceramic materials. These materials are then used to create building products like tiles and pavers, as well as advanced technical ceramics. Instead of extracting new clay or minerals, the company treats waste as a resource, reducing landfill use and cutting carbon emissions by at least 20 to 30 percent compared to traditional ceramics.

Seramic equiment

This is where the circular economy becomes real. Ceramics have always been made from earth. Seramic simply expands that idea by using what has already been taken from the earth and discarded. The result is a loop rather than a line. Waste becomes material, material becomes product, and eventually returns without adding new burden.

One of the company’s most important projects is ReThink Seramic Flora, a high temperature ceramic designed for thermal energy storage. It can store heat at temperatures up to 1250°C, making it useful for solar power systems and industrial heat recovery. This connects ceramics directly to the energy transition, allowing renewable energy to be stored and used when needed.

Seramic's material

The company is also working with partners like Bee’ah in the UAE to scale waste conversion systems and address growing volumes of industrial ash.

Where this is going is clear. Ceramics are no longer just tiles or bricks. They are becoming part of energy infrastructure, waste management systems, and low carbon manufacturing. Companies like Seramic are turning one of the oldest materials on earth into something that fits a future built on circular thinking.

24 7 renewable energy: how solar, wind, batteries and AI SaaS replace fossil fuels

AI can boost solar SaaS
AI can boost solar SaaS

Solar and wind were once framed as intermittent, unreliable, and dependent on fossil fuels to fill the gaps. That argument is fading fast.

A new report from the International Renewable Energy Agency based in Abu Dhabi makes something clear that many in the industry already suspected. When solar and wind are paired with battery storage, they can deliver reliable, round the clock electricity at costs that compete with, and often beat, fossil fuels.

In the best solar and wind regions, these hybrid systems are already delivering what used to be considered impossible. Continuous power. Stable pricing. Lower costs. The numbers tell the story. Solar paired with storage is now delivering electricity at roughly 54 to 82 dollars per megawatt hour in high quality regions. That is already below or competitive with new coal plants in China and significantly cheaper than new gas plants globally.

Costs have not just dropped. They have collapsed. Since 2010, solar installation costs have fallen by about 87 percent. Wind is down by more than half. Battery storage has dropped by over 90 percent. That last number matters most because storage is what turns intermittent energy into firm power.

This changes everything, especially for artificial intelligence.

AI systems and data centers are among the most energy hungry infrastructures ever built. They do not tolerate downtime. They do not accept fluctuations. They need constant, predictable electricity. Until recently, that meant fossil fuels or nuclear.

Hybrid renewable systems are being designed specifically to meet these demands. Solar generates during the day. Wind often peaks at night. Batteries fill in the gaps, shifting energy into the hours when it is needed most. The result is a system that can run continuously, without burning fuel.

In places like the United Arab Emirates, large scale solar plus battery installations are delivering gigawatt level power at around 70 dollars per megawatt hour. Wind plus storage is also becoming competitive, with costs expected to drop further over the next decade.

Projects that combine solar, wind, and storage can now be built in one to two years once permits are secured. That is faster than most new gas plants. Faster than nuclear by an order of magnitude. Speed matters when demand is rising as quickly as it is now.

Every new model, every data center, every layer of digital infrastructure increases the pressure on energy systems. AI companies are now quietly becoming energy companies, signing long term deals and building their own power strategies. They are not looking for green energy as a branding exercise. They are looking for reliability and price stability.

There is also a geopolitical layer. Fossil fuel markets remain exposed to disruption, whether through conflict, shipping chokepoints, or price volatility. Renewable systems, once built, draw on local resources. Sun and wind are not shipped through straits or pipelines. They do not spike in price because of a crisis.

When solar, wind, and batteries are combined, they do more than reduce emissions. They stabilize economies. They reduce exposure to global shocks. They give countries and companies more control over their energy future.

The next phase is optimization, and this is where AI comes back into the picture.

AI is not just a consumer of energy. It is becoming the system that manages it. Energy companies are increasingly using AI powered energy management platforms, predictive analytics software, and grid optimization SaaS tools to balance supply and demand in real time. These software as a service platforms allow utilities and developers to forecast solar output, predict wind patterns, and decide when to store or release energy from batteries.

AI driven demand response systems are already helping large users, including data centers, adjust consumption dynamically. Smart grid software, cloud based energy platforms, and machine learning models are optimizing when electricity is used, where it is sent, and how it is priced. These tools reduce waste, improve efficiency, and increase the value of every kilowatt generated.

For AI companies themselves, this creates a feedback loop. The same artificial intelligence systems that require massive amounts of energy are now being used to make renewable energy systems more efficient and more reliable. Energy optimization software, battery management systems, and renewable forecasting tools are becoming essential infrastructure.

Solar and wind with storage provide the physical layer. AI provides the intelligence layer. Together, they create an energy system that is not only cleaner, but smarter.

As costs continue to fall, with projections suggesting another 30 percent drop by 2030 and up to 40 percent by 2035, the combination of renewable generation, battery storage, and AI optimization will become the default model rather than the alternative.

 

A summer of sugar wax or time for laser treatments? The environmental answer

How to make sugar wax. It’s easy and edible.

Green Prophet readers know we write a lot about hair. We have covered the halal and the haram sides of hair removal for Muslims. We have written about sugar waxing, Persian sugaring, threading, and the beauty secrets that came out of the Middle East long before salons started calling them trends. Our articles on sugar wax broke the internet a few times.

We have also written about people who would rather grow it all out. For them there is Januhairy, where body hair becomes a statement rather than a problem. We have written about Persian women with mustaches, once considered beautiful in Tehran. We have even looked at natural ways to lighten darkened knees for women whose prayer practice leaves a mark on the body.

Januhairy bikini line no shavingHair is never just hair. It is religion, culture, modesty, rebellion, fashion, hygiene, sexuality, and sometimes just one more thing we are tired of managing.

(If you have come looking for a hair transplant, you’ve come to the wrong place, but we did see tens of people in the airport of Istanbul with new plugs in their scalp – so that’s probably the place).

Today we are talking about lasers.

Once a woman or man reaches an age where laser hair removal is appropriate, it may be one of the more ecological choices for people who already remove hair regularly. That part matters. If you love your hair, keep it. If you remove it for religious, cultural, personal, or practical reasons, then it is worth asking how much waste your routine creates.

Razors, plastic cartridges, shaving cream bottles, wax strips, applicators, salon paper, depilatory creams, packaging, and water use all add up. Waxing every month or shaving every few days is not just a beauty routine. It is a supply chain.

I have spoken with women and men who have used laser treatment to remove hair on different parts of the body. Most say the same thing. After years of waxing or shaving, five, six, or seven laser sessions made the whole business easier. Not always perfect. Not always permanent forever. But enough to remove much of the hassle.

For many Muslims, hair removal is recommended within a forty day rhythm, depending on practice and interpretation. For traditional Jewish women, preparation before the mikveh can include careful grooming and cleansing before immersion after menstruation. How much hair is removed is personal, but the body, water, and ritual all come into the conversation.

Laser treatment enters that space in a practical way.

Ask questions at the laser clinic. Before any treatment starts, know what you are getting into
Ask questions at the laser clinic. Before any treatment starts, know what you are getting into

There are different kinds of machines, and this is where things get real. Not all laser treatments are equal. Some of the newer machines have better cooling systems, skin sensors, and settings for different skin tones. Someone in my family uses a more expensive machine and is told to stay out of the sun for about three days after treatment. That is manageable.

Other clinics are far more restrictive. We tried one while on holiday in Canada and were told to stay out of the sun for two weeks. Two weeks in summer is not a small ask. That is not sustainable unless you are planning your life around your legs.

The common machine types include Alexandrite, Diode, and Nd:YAG lasers, along with IPL, which stands for intense pulsed light and is not technically a laser. Alexandrite lasers are often used for lighter skin with darker hair.

Diode lasers are common and can work across a broader range of skin tones.

Nd:YAG lasers go deeper and are often considered safer for darker skin tones when used by experienced professionals.

IPL is usually cheaper and more available, including in some home devices, but it is less targeted and may require more sessions. People can buy them online and teenagers use them often, but the efficiency is almost not worth it.

Januhairy, grow a unibrow, remove a unbrow, long armpit hair, janu hairy, black woman chest hair
Photos from Januhairy

This is why you should ask questions before booking. Ask what machine they use. Ask whether it is a true laser or IPL. Ask if the operator has experience with your skin tone. Ask how many days you need to avoid sun before and after treatment. Ask what cooling system they use. Ask if maintenance sessions are likely later. And how many? Laser treatments aren’t recommended for teenagers before they hit peak puberty. Chances are the overdrive hormones will not have any effect on rampant hair growth.

The American Academy of Dermatology warns that laser hair removal can cause burns, scars, or permanent changes in skin color when done badly, especially in inexperienced hands. Cleveland Clinic says tanned skin can make the procedure less effective and increase side effects. Mayo Clinic also advises avoiding sun exposure and tanning beds before treatment, using sunscreen, avoiding sunless tanning products, and stopping waxing or plucking before sessions.

That may sound like a lot, but it is better to know before you pay. The machine matters. The person using it matters more.

When in doubt ask a friend of yours with smooth arms if they have ever been hairy. If yes, ask them about laser treatments.

Are you tired of shaving cream, sticky sugar wax concoctions? Maybe it's time for a laser.
Are you tired of shaving cream, sticky sugar wax concoctions? Maybe it’s time for a laser.

From an ecological perspective, the logic is simple. Fewer treatments over time can mean less reliance on disposable products, less plastic, less packaging, less chemical runoff, and less repetition. It is not perfect. It is still a treatment. It still uses energy. It still costs money. But compared to a lifetime of razors, wax strips, creams, and salon waste, laser hair removal starts to look like a reduction model rather than a consumption model.

It is also not for everyone. Light hair, red hair, grey hair, hormonal conditions, darker skin tones treated with the wrong machine, pregnancy, medications, and recent sun exposure can all complicate results. A good clinic will tell you that. A bad clinic will sell you a package before asking enough questions. We actually had a clinic near Toronto turn us away because it was summer and the lasers might do damage if we came into contact with the sun.

So maybe the question is not whether you remove hair or leave it alone. That is personal. It can be cultural. It can be religious. It can be nobody’s business. The better question is how you do it.

Good luck and enjoy your summer. We love you.

Bake a New York Cheesecake for Shavuot

New York style cheesecake for shavuot
New York style cheesecake for Shavuot

This light, creamy cheesecake fits into your green Shavuot, especially if you make it with organic cheese and eggs. It’s also light on sugar.

The ancient Romans left a simple cheesecake recipe: ricotta cheese, honey, and eggs.  Pour into a clay saucer. Bake over coals. That still works, but for the Jewish holiday of Shavuot, we favor this recipe. It’s  got just that hint of lemon and vanilla that makes you feel like you need another slice now, before someone else lays hands on it. And it fits into your domestic Jewish eco-activities, because it’s home-made – much healthier and more delicious than margarine-laden bakery products.

Have three bowls at hand, 1 large, 1 medium, 1 small. Prepare a cake pan either with baking paper or by greasing it with sweet butter and coating it with flour.

And do not preheat the oven: you want to start baking cold.

New York Cheesecake

6 servings: double the ingredients and bake in a larger pan for 12 servings.

Ingredients:

6 eggs

3 Tblsp. sugar, plus 6 Tblsp. later

500 grams – 1 lb. – 2 cups –  soft, creamy white cheese – here in Israel I use 9% white cheese

1 tsp. vanilla essence

Juice of 1 lemon

6 Tblsp. sifted flour

Method:

1. Separate the eggs.

Keep the whites in the large bowl.

Put 3 of the yolks in the medium bowl; in the small bowl, the other 3 yolks.

2. In the medium bowl, beat the 3 yolks with the 3 Tblsp. sugar and all of the cheese. Mix well till smooth.

3. Whip all the egg whites till stiff.

4. To the whites, add the 6 Tblsp. sugar and whip till the whites make smooth peaks.

5. Add the flour, the lemon juice, the 3 yolks from the small bowl and the vanilla.

Mix very well. This is the batter.

6. Pour 2/3 of the batter into the baking pan.

7. Mix the remaining third of the batter into the cheese mixture. Mix well.

8. Pour this new mixture straight into the center of the batter in the pan.

Bake at  300°F – 150° C for one hour.  Turn the oven off, but don’t remove the cake: just open the oven door a crack and let the cake cool inside. Once cooled down, store the cake in the fridge.

There’s something quietly beautiful about what Rebloom Studio is doing, and it starts with waste. At wholesale flower markets, mountains of unsold blooms are tossed out at the end of each cycle. Perfect flowers, just not sold in time. Most of them are burned or dumped. Rebloom takes that moment and turns it into something else.

We know paper as something made from tree pulp, but in Asia, paper is made from rice waste, and in schools everywhere, kids are making paper with old paper –– and are adding flowers, leaves and other organic material to the mix. In Japan, they made newspapers with seeds embedded in the upcycled paper so when composted the waste turns into flowers.

How about flowers themselves turning into paper and clay?

Rebloom’s Petal Vase is made from discarded flowers, pulped down and mixed with Korean paper fibers and a natural binder. What you get is not a polished, perfect object, but something closer to the mushy, memory of a flower which is textured, uneven, a little unpredictable. Each vase carries the trace of whatever went into it: different tones, flecks of color, the ghost of the flower that was.

There’s a glass cylinder inside, removable, which holds the water and stems. That’s practical. It keeps the outer shell dry so the material doesn’t break down during use. The outside stays raw, untreated, almost fragile-looking, even though it holds its shape.

And when you’re done with it, really done, it can go back to the earth. No plastic, no long afterlife in a landfill.

There’s a design shift happening right now where imperfections are not hidden but exposed. For home decor, that could mean something. Instead of mass-produced sameness, objects tied to seasonality, to place, even to failure. A bad sales day at a flower market becomes a new product line.

For the floral industry, there’s a second life emerging. Unsold inventory doesn’t have to be a total loss. It can be aggregated, processed, turned into something with value.

Muslim potter shapes the 99 names of God into clay

0
My latest ceramic series explores the 99 names of God in Islam through 99 unique sculptures inspired by seed pods. Never forget the seeds planted by our ancestors that we can use now as sustenance and inspiration in a noisy and unjust world. What seeds are you planting that can nourish future generations in their times of trial and injustice? There are so many wonderful possibilities of what that can look like.
Ceramic tiles and the 99 names of God

In a studio in the DC Maryland Virginia area, ceramic artist Alison Kysia is working with clay in a way that feels both grounded and personal. She makes pottery and abstract Islamic sculptures, and one of her recent works focuses on the 99 Names of God in Islam, a concept borrowed from Judaism where there are 72 names for God. Christians have about 30 names for God.

Kysia, who shares her work as @786arts, identifies openly as a Muslim woman artist. Her practice includes handmade pottery, sculptural pieces, and socially engaged art projects that connect people through making.

A recent piece, Al Musawwir III: The Artist, is named after one of the 99 Names of God, often translated as The Shaper. The work includes 99 individual ceramic tiles. Each tile is painted by hand with teal bursts that look like small worlds or organic forms spreading outward. Together they sit in a single black frame, measuring about 17.5 by 21.5 inches.

Her idea is simple and strong. Each pottery tile holds its own pattern, but the full set builds something larger. It is repetitive but not uniform. You can stand close and look at one tile, or step back and take in the whole.

Kysia shared that the reaction from buyers has been emotional. One collector told her that the idea of living with a piece connected to the 99 Names gave them chills and felt deeply moving. She also recently sold a sculpture for a four figure price, a personal milestone.

Her work also carries a message about identity. She speaks directly about the way Muslims are treated and represented, and sees her art as a way to show something else. Not an argument, just presence through material and form.

Clay does a lot of quiet work here. It comes from the earth, it holds marks, it records touch. In Kysia’s hands it becomes a way to think about faith without needing to explain it too much.

99 seed pods for God?

 

She then went on to do the same with crafting seed pods. “My latest ceramic series explores the 99 names of God in Islam through 99 unique sculptures inspired by seed pods.
