Volocopter VC200 – 18-rotor electric helicopter takes flight

Volocopter VC200

Greener transportation options have become a priority in the modern world. Greener and more efficient vehicles of all types are eventually becoming the standard. Even helicopters are becoming greener. One German company, E-volo, designed several electric helicopters, and one of its models, the Volocopter VC200, recently passed its first flight tests.

Now, we are so fond of the flying cars, that even designers are trying their hands on some out of the world renderings of their own thought of a prospective roadable flyer. This one from the ZEEP Design show is a car that transforms into a helicopter, now that can be a realistic idea if for those cars start taking to the skies on a regular basis. (Pics)

Harnessing Direct Solar Power To Propel Tiny Nanomaterial Machines

Harnessing Direct Solar Power

A four-finned rotor (center) floating on a pool of water spins when exposed to sunlight.

The sun is the most abundant source of renewable energy. But all the technologies that capitalize on sunlight, including photovoltaics and biofuels, require intermediate steps and infrastructure to turn the sun’s rays into something that can be used to perform work in a machine. Researchers at the University of California, Berkeley, are using carbon nanotubes to build small, simple waterborne machines propelled directly by sunlight. In theory, they say, these machines could be scaled up to make energy-generating pumps directly powered by the sun.

Mini-Windmills Could Soon Be On Roofs Across Europe And US

Mini-Windmills Could Soon Be On Roofs Across Europe And US 
 Mini-Windmills

They are small and look more like art than innovation. But the mini-windmills built by a British company could soon be on roofs across Europe and the US — if German energy giant RWE has its way.
