Trials have just been finished on a new kind of wind turbine — an inflated, helium shell containing traditional blades that floats in the air stream. The airborne turbine is designed to capture stronger, high-altitude winds to provide a clean, portable and power energy option.
If you want to have a super green outdoor party that even Al Gore or Ed Begley Jr. would be happy to attend, make sure you get yourself some of these new wind-powered pendant lamps from Ikea.
Out in the ocean, stuff sinks. Usually this is a bad thing, but if you're a submarine or one of these newfangled wind turbine systems from WindFlip, sinking is exactly what you have in mind.
Of all the different kinds of renewable energy, wind might be both the easiest to manage and the most frustrating. Turbines are relatively cheap and easy to build and deploy, but wind is a fickle mistress, and an idle turbine is barely fit for birds to poop on. Solution? Send the turbine to the wind instead.
Called "Green Power Island," the goal here is to leverage not just one green energy solution, but mash a bunch of them together to create one whopper of a renewable powerhouse. It's more than what you see on the surface, too, thanks to some clever engineering.
In what can't possibly fail to be a symbolic gesture, old coal mines in Germany are being repurposed into giant storage tanks for wind energy.
Renewable energy's dependence on weather is one of the factors that's kept it from replacing oil and coal and nuclear and other nasty evil polluting power sources for day-to-day use. In a stroke of genius, scientists in the U.K. have stuck a solar powered generator onto a rain and wind-powered generator to make an all-weather power harvester.
Shepherds Flat Wind Farm, currently under construction in Oregon, is set to become the world's largest wind farm when it's completed next year. And that's thanks in part to a new $100 million investment by Google.
Some gadgets still require you to use AA batteries, like a Wii or Xbox 360 controller or a cheap digital camera. Wouldn't it be handy to not have to pop rechargeable batteries into a charger and wait for it to juice up? A new battery design concept would eliminate the wait time by letting you wind up the battery to recharge it.
Two Germans — engineer Stefan Simmerer and TV host Dirk Gion — recently set out on an epic 18-day road trip that saw them traveling over 3,000 miles across Australia. The coolest part? They did it in a vehicle powered only by a kite and wind turbine and broke three world records in the process.
