I like the concept of ‘a wind turbine for every home’. It just makes more sense than building one gigantic one with blades as tall as the Statue of Liberty. So, for years, I have followed the designs — from 60s ‘hippie sustainablity’ to the 90s ‘zombie apokolyps’ types who kludge up new models in an effort to get more bang for their buck. Now, these ‘wind trees’ may not be cheap BUT, they just look cool and make a ton of sense to me.Quote:Picture a steady breeze blowing through the leaves of a tree. Now imagine these leaves could do more than simply churn in the current of air—what if they could capture the wind and transform it into renewable energy?
Energy from wind is the fastest-growing source of electricity in the world, according to the Union of Concerned Scientists, an environmental and social research institution. This development of wind power has mostly taken place on a large scale, usually by utility companies providing power to a grid of millions of customers. That’s because wind energy is most efficient when it’s capturing very strong winds, more common in remote areas and at heights greater than 50 feet off the ground. Those turbines need to be as tall as a five-story building, and they take up a lot of horizontal room, too—several hundred feet per turbine, in many cases. They also require more maintenance than solar panels.
All of these factors make it challenging to capture wind energy in small amounts. But that hasn’t stopped companies from experimenting in the hopes of one day allowing individual homeowners to capture energy from their own backyards or balconies, and reduce their reliance on fossil fuels.
Last December, two “wind trees”—or arbres à vent—quietly churned in a plaza in Paris, as world leaders met for the historic climate talks at the Le Bourget conference center nearby. Developed by a French company called New Wind, the “trees” had plastic “leaves” painted green, with curves that held dozens of tiny blades soundlessly harnessing the wind no matter which way it blew. Unlike larger industrial turbines, which need winds of over 22 miles per hour to function, the leaves captured energy from wind speeds of less than five mph.
There is a lot more to the article and a nice gif of two trees ‘in action’. imo, it’s pretty cool stuff… science imitating Nature to gain free energy. It just makes sense.August 25, 2016 at 10:28 pm #192504JKBargerParticipant

sorry, just reminds me of this:[video width=425 height=344 type=youtube]udwdNxDqScI[/video]
