Researchers at Fraunhofer-Gesellschaft have built a new type of steel blade for wind turbines formed from a 1.0 mm steel sheet and featuring integrated, folded reinforcement. Today’s wind turbines use very large rotor blades made with fiber-reinforced plastics that are almost impossible to recycle. But steel blades recycling ability exceeds 90 percent. Plus they cost […]

Vortex, founded in Spain by three men whose co-founder scientist David Yáñez, has developed a wind power generator without a turbine with wing blades. The Vortex generator uses vorticity, a word formed from the activity potential of a vortex. A vortex can be seen where water twists around going down a drain, in the air […]

A University of Texas at Arlington (UTA) research associate and electrical engineering professor have designed a micro-wind turbine that generates electrical energy.  Their target looks to be an innovative solution to cell phone batteries constantly in need of recharging and home energy generation where large wind turbines are not possible. Smitha Rao and J.-C. Chiao […]

Researchers at the Department of Energy’s Pacific Northwest National Laboratory (PNNL) and Bonneville Power Administration (BPA) identified two unique methods, one a hybrid energy production and storage approach at two eastern Washington locations to put them into practice. Using wind energy the PNNL calculates enough wind energy could be stored for about 85,000 homes each […]

One’s first impression is – it won’t work.  But some innovative and enterprising folks have driven the wind through a funnel idea to what seems to be a successful field trial. Brian Wang’s NextBigFuture site spotted the small firm’s press release and ran a post.  That in itself is an acknowledgment the technology is interesting. […]
