A new type of wind turbine harvests not only electricity from the wind, but clean water from the air, by condensing humidity from even the driest climes. One prototype turbine is apparently collecting 16.3 gallons of water an hour from the desert air over Abu Dhabi, according to the company that builds it.
We’ve seen plenty of concepts designed to lessen the physical burden of being a member of the military — Marines using portable renewable power stations, clothing that charges radios and GPS devices. But there’s not much being done to address drinking water, one of the heaviest yet most critical battlefield necessities. Now the Oak Ridge National Laboratory might have a solution that can help lessen the weight of water.
In a breakthrough so hot it's cool, Spanish researchers have figured out how to make water freeze at room temperature. By artificially manipulating the mechanisms by which water condenses in the atmosphere, the researchers found a means to trigger ice formation at far higher temperatures than water's usual freezing point, a development that could lead to better artificial snowmaking, more efficient ice skating rinks, and better freezer technology.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
