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 […]
Parasites need to adapt to continue living off their hosts. Almost every type of organism on earth faces parasitism, including us humans. Ecologists have assumed that the parasite has influenced the DNA evolution of its host, and some new science from Israel explores how this relationship works at the gene level. In the course of […]
Research and development focused on the aerospace industry has spawned dozens of designs useful in everyday life. Now LifeBeam, an Israeli company that designs high-end gadgets worn by jet pilots and astronauts, has designed a “smart” cycling helmet fitted with sensors that can track your heart rate, gait, and associated calorie burn. Not a cyclist? Then check […]
Those of you who grew up in countries blessed with ample fresh water supplies may have fond memories of going fishing as a child with paper carton filled with small, wriggly earthworms. Most people in the Middle East, however; due to chronic water scarcities, have seldom seen this little squiggly creature that is often found […]
Nanoflow technology’s Quant e-Sportlimousine is fast. Its 920 horsepower engine can accelerate this sleekly luxurious car from 0 to 100mph in 2.8 seconds. Its maximum speed is 217.5 mph. Nanoflow claims this electric car has a range of 373 miles with a full tank. And when it does run low on fuel, you’ll need to […]
Almost exactly one year ago Green Prophet revealed that King Tut’s jewelry contains ancient comet dust. Now the ancient Egyptians will leave their mark on a passing comet as a spacecraft named after an Egyptian obelisk takes a selfie before attempting a soft landing on a comet.
Newspapers like Bloomberg are calling the newly “legalized” cannabis business in the United States the next gold rush. If legalized throughout the US, the cannabis business will eclipse wine. That’s something worth about $40 billion a year. So “prospectors”, inventors and investors there are laying down their stakes and claiming access to new territory. […]
Elementary and middle school students from schools across Qatar recently tested their robotics know-how.
Some news that Trekkies will love, and which could be applied to clean up our seas: tractor beams to the rescue!
The tide is turning on American cannabis laws. More and more states are opting for medicinal and recreational use of marijuana and whether you are for or against it, there is an interesting effect: technologies being applied for growing cannabis will help make our planet make better food.
Are grandma’s heirloom tomatoes Genetically Modified Organisms (GMO)? What about Lebanese cucumbers or the maize that Native Americans transformed from a meager ankle-high grass into long-eared mazes of golden corn? What is so scary about GMO?
China’s economy is growing exponentially. So is the needs of its population. To keep ahead of the food curve, China’s Yuanda Group just bought the Israeli company AutoAgronom for $20 million.
