This unusual solar tower was designed by Israeli architect Haim Dotan for AORA Solar. It is set to launch on June 24 in South Israel. The tower has 30 tracking mirrors (heliostats) that reflect sunlight towards the top of a 30-meter high solar tower. The top of the tower has a special solar receiver and… [Continue Reading]
We just featured the largest wind turbine in the world, now here’s something at the opposite end of the spectrum: a household wind turbine. In the last few years, we’ve seen a lot of mini-wind turbines that haven’t turned out to be very useful. But the Windspire turbine from Mariah Power sounds interesting. The Windspire… [Continue Reading]
We just wrote about the new LED streelights in Ann Arbor. Now we find these self-contained streetlights that generate 100% of their power from the sun and the wind. During the day, solar power is stored in a battery at the base of the light pole. At night, they illuminate while continuing to generate power… [Continue Reading]
The tallest wind turbines in the U.S. have been installed in Texas — the Vestas V90 turbines are 345 feet high, and are rated at 3 megawatts each. They are part of the 63 megawatt Snyder Wind Project, a wind farm that’s just been installed in western Texas.
The Navitas is a bike trailer that generates its own power using the sun and wind. Designed by Paul Smith, a student at University of Derby in England, the trailer has a rear wheel that splits three ways to become a vertical axis turbine. There is also a compact solar panel to help to provide… [Continue Reading]
Today, I wrote a post for TreeHugger about a company that is proposing to build a colossal magnetic levitation wind turbine. Magnetic levitation (or maglev) is an interesting technology that has been around for a while.
I first wrote about these wind micro-wind turbines for TreeHugger in March. Since then the microturbines have become available for sale through the Motorwave website (here’s a direct link to the store). Right now, shipping costs from Hong Kong are about $300, but Lucien Gambarota, the inventor says he hopes to offer the turbines for… [Continue Reading]
There’s a small town in Germany called Dardesheim, that relies almost entirely on renewable sources for its energy needs. The town’s goal is to use 100% renewable power, and become known as German’s “Town of Renewable Energies”. Dardesheim already has some huge wind turbines in place, and many solar roofs installed. Last year they installed… [Continue Reading]
Note: Images and Video © Lucid Dream Productions Wind turbines designed to be installed on rooftops are generating a lot interest lately. These compact turbines can be located on top of buildings, or attached to other parts of large structures like bridges. In turns out, though, that installing wind turbine in a city environment is… [Continue Reading]
Europe’s first concentrated tower open recently near the sunny southern Spanish city of Seville. The 11 megawatt plant took four years to build — it was created by a Spanish energy company, Solucar. The tower project is called “PS10″ and it uses 624 large movable mirrors called heliostats. Each of the mirrors has a surface… [Continue Reading]
