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 […]

Eddy is artificial intelligence for vertical farms and hydroponics

flux-device-prototype-1.jpg

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 […]

10 Inventions to Save Earth’s Water

water-shower1.jpg

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 […]

Pee Power is making energy from urine in Africa

Pee-power-project.jpg

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 […]

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 […]
