In the middle of Harlem on a derelict plot of land where old men used to play cards, with no kids allowed, is growing one of the most exciting social projects I’ve seen this year. Harlem kids that were eating Twix bars for lunch are now eating fresh greens –– food that they and their mothers are […]
Now that I am developing flux, a space-age gadget for making hydroponics simple and efficient I can’t help but promote hydroponics everywhere — even and especially hydroponics from space! This week NASA scientists harvested their first space-grown food, grown on water with nutrients using hydroponics. This site is becoming a bit of an address for hydroponics, and we’re […]
There are loads of ways to unload your junk. You can haul it away to the landfill, leave it at the end of your driveway or lawn for others to pick up – or have a garage sale. When you go online you can go to Freecycle to give it away for free or navigate […]
Strong crop yields, higher productivity and slower growth in global demand should contribute to a gradual decline in real prices for agricultural products over the coming decade, but nonetheless, prices will likely remain at levels above those in the early-2000s, according to the latest Agricultural Outlook report produced by the OECD and the United Nation’s Food […]
As spring turns into summer, the Khalifa fund’s investment in Abu Dhabi hydroponic agriculture is beginning to pay off. The Khalifa fund for enterprise development was Launched in 2007 to help local enterprise in Abu Dhabi. At the beginning of 2015, Ahmad Kalfan Al Romaithi revealed that Dh 130 million (approximately 35 million US dollars) […]
A celestial tryst between the CEO of Roman gods and the Roman goddess of love and beauty? This seems hardly a match made in heaven. You might even say this relationship is star-crossed. But watch the western sky just after sunset on Tuesday, June 30th and you’ll see a rare conjunction between a beautiful bright […]
Here’s a story about ingenuity and creativity. About a man who uses a solar cooker to prepare meals. If you wish, you can see it as a testament to how the human spirit prevails even under the toughest conditions. If you’re willing, you can see it as an opportunity, a mutual interest, or a proposition […]
“My God, it’s full of stars!” Fans of Arthur C. Clarke’s classic science fiction novel 2001 A Space Odyssey might recognize these as the words of astronaut David Bowman, awestruck by revelations of the deep mysteries of space. A team of astronomers from Tel Aviv University and UCLA discovered more than a million newborn stars […]
Even the US Customs guy at the New Jersey airport gave me an approving nod: “A technology for hydroponics?” He flips over my business invitation from the NY company to see if there wasn’t something inside. “Well, you know, it’s still,” in a fake finger-wagging voice, “…illegal here?” he says, waiting for my reply. There […]
Oil prices have fallen considerably over the past two years. But this isn’t the first time the price of a core society resource has dropped so drastically. The economic history of salt is an interesting lesson for our time. Middle Eastern countries spend millions of dollars and consume more than one hundred million kilowatt-hours of […]
The flux team, one of the featured companies at the Innovation Pavillion at the annual Agritech Conference. Agrivest for investors kicked off the week of “agmania”. Steve Rhodes the CEO and co-Founder of the Trendlines Group opened this year’s Agrivest conference in Israel showing some interesting trends. Last year 2014 saw a steady increase to $2.36 […]
Eddy is like the “easy button” for hydroponics The United Nations is screaming it –– and California is feeling it: drought caused by climate change is killing the way we grow food. And it will only get worse. Thought leaders want a shake up of conventional agriculture, because large mono-crop farms are not producing enough to […]
With drought looming in California, but in many regions of the world include Yemen, Green Prophet honors this year’s Earth Day by digging into the archives so you can share 10 ways to collect and save fresh, potable water. 1. Sea “water cone” evaporation This low-tech method of collecting fresh water in involves placing an inverted plastic “water cone” […]
Harvesting water from the air is not a new idea. Arid countries like Yemen are already using low tech watercones to funnel sea water to drinking water. Another funneling device is being developed by an Italian designer to trap water vapor in a Warkawater tower to harvest potable water directly from the air. Still another device, called the […]
How can the environment around computers be used to hack data? Computer scientists have now determined that it’s possible to send data or “steal” data by using heat transfer between computers – those typically used as servers in high profile institutions like banks and police. Their exercise in hacking heat points out vulnerabilities in today’s […]
It’s already well known that manure or poop can be recycled for making products like paper as well as creating biogas power from methane gas. Turning urine or pee into electricity is another matter. This readily available “resource”, whether it be from animal or human origin, is now being experimented with to actually generate electricity by using our […]
Like Israel’s Softwheel for wheelchairs and bikes, Goodyear is asking: Can new ways of engineering tires extend the cruising ranges of electric cars to make them more saleable in the aftermath of the the demise of Shai Agassi’s Better Place electric car venture? Despite some success in selling electric cars like Nissan’s Leaf model and General […]
Drones, those small, unmanned remote controlled airplanes with cameras can now be ordered by anyone online. They freak some people out. Not everyone loves the idea of a drone honing in on you in your backyard, but in agriculture, forestry and even in conservation they are the hot topic of the year. How can we […]
Food Tech, on the surface of things, sounds like something you might not want to bite into, especially if you practice permaculture and organic gardening. But dig deeper as guests from Israel and France learned last week in Jaffa during the So French, So Food week, which hosted 20 top French chefs visiting Israel. They […]
The Doomsday Clock, which measures the likelihood of global catastrophe, last month ticked a minute closer to “midnight” — the apocalypse. The symbolic clock was set to 11:57 by a board of atomic scientists featuring 17 Nobel Laureates, who warned that the planet, beset by climate change and nuclear proliferation, faced extraordinary and undeniable threats […]
Finding ways to augment supplies of fresh drinking water have been around for years. These ideas vary from basic “low tech” ones like a Yemenite funnel water cone to extract fresh water from saltwater to using water created by aircon units. Purifying sewage systems to create safe, drinkable fresh water are also being tried; and have received visible […]
Engineers at Lockheed-Martin recently developed and patented a molecular filtration membrane called Perforene which can desalinate seawater using only 1/100th the energy of the best existing desalination systems. Perforene is made from graphene, the exciting new nanomaterial which comes in the form of one-atom thick sheets of carbon atoms. Like an overzealous nanotechnology, graphene seems […]
Investments in solar energy innovations are not dead! Remember those weird and wonderful solar energy harvesting tulips planted in Israel and Spain? Seen miles away the sky-high tulips have found a new commercial home – in Ethiopia, the company announced last week in a press statement. We’ve covered Aora over the years and thought possibly […]
British economist Milton Friedman once warned that if you put the government in charge of the Sahara Desert, in five years you’d have a shortage of sand. Whether governments or free markets are to blame, it is possible to deplete abundant resources such as Irish rain. Now thanks to global obsessions with concrete icons, fracking […]
You know you should have done it. The DropBox folder is there, the extra hard drive is on the shelf. Hey, your partner even set up a wifi link to help you back up your files from any room in the house, without cords. But you have fallen into the trap of laziness. You are […]
