A retired Swiss biology teacher has built one of the most unusual diving devices ever featured on Green Prophet: a sleek, fish-shaped underwater breathing...

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 allged French concept for a solar-powered desalination vessel designed to bring drinking water to coastal communities facing drought, storms, and infrastructure failures.

The Hydrophilis rebreather is a new scuba system that could make diving safer and more fun.

All air conditioners release water. That's Physics. Cities like Los Angeles pour billions of water down the drain every year. And while home owners who are savvy to water reuse are finding ways to use AC water in the garden (here are 5 ways to use air con water at home), or in art studios (it's basically free distilled water), cities could save water in meaningful ways by using creative ideas. These are solutions you can send to urban planners and those running smart city accelerator programs. Pick one of them and you might win the grant! 

Current goals are to treat neurological disease like Parkinson’s and restore autonomy to people with severe physical limitations by controlling exoskeletons and prosthetics. There’s also huge potential to improve cognitive abilities such as memory, attention, and languages.

Hydrophilis, Oliver Isler’s experimental rebreather suit, reimagines diving by reducing drag, eliminating bubbles, and bringing humans closer to the natural movement of marine life.

Unlike solar power on Earth, which is limited by night cycles, weather, and seasons, the Moon offers something close to uninterrupted exposure to the Sun. By placing solar infrastructure in orbit or along the lunar surface, engineers could generate continuous clean energy at a scale that may exceed global electricity demand,  the Japanese scientists say.

Reliable light matters in more places than ever. It matters on a back road after sunset, in a cabin with limited power, and at home during a storm outage. Research across sustainability guidance, preparedness resources, and off-grid living coverage points to one clear takeaway: people want lighting that works well, lasts longer, and creates less waste.

AI and bio-plastics have a formidable crew looking to solve the plastics problem. It uses AI to match opportunities to existing machinery.

For millennia, the Middle East's water crisis seemed an immutable fact of geography — a region defined as much by what it lacked as by what lay beneath its sands. Today, a convergence of plummeting solar costs, advancing membrane technology, and hard-won engineering expertise is rewriting that story.

Stepping up to democratize the moon is an EU-funded company, Deep Space Energy, which has just raised more than $1 million USD as a seed fund to help it create energy generators on the moon.

For those unaware, SpaceX has already shifted focus to building a self-growing city on the Moon, as we can potentially achieve that in less than 10 years, whereas Mars would take 20+ years.

Israel’s water and agricultural technologies didn’t emerge from ideal conditions. They were developed under pressure: low rainfall, saline water, political isolation, lack of energy resources, and the constant need to feed a growing population with limited land. Over the years, I’ve written about many of these companies not as miracle-makers, but as problem-solvers. That’s what makes them relevant to places like Somaliland. Israel was the first country in the world to recognize Somaliland as an independent state although Ethiopia has been treating the nation as such for decades.

Masdar is the the UAE’s flagship renewable energy company. Compare it to Neom in Saudi Arabia. Masdar has become one of the world’s most active clean energy investors, with projects in more than 40 countries across six continents. Established in 2006 and jointly owned by ADNOC, Mubadala, and TAQA, Masdar operates and develops solar, wind, and green hydrogen projects with a current portfolio exceeding 50 gigawatts of capacity. Masdar also buys companies, and paid $50 million for this US business Terra-Gen last year. 

Berkeley-based startup Copper has raised $28M to scale its battery-equipped induction stoves, offering a practical, plug-in alternative to harmful gas cooking. By cutting indoor air pollution, eliminating costly retrofits, and doubling as energy storage, Copper’s innovation helps households shift to cleaner, healthier kitchens and a greener energy grid.
