Do the best offshore wind turbines operate with a horizontal or vertical-axis mechanism? That question is being reexamined by Sandia National Laboratories’ wind energy researchers, who are now re-evaluating vertical-axis wind turbines (VAWTs) to help solve some of the problems of generating energy from offshore breezes using horizontal-axis wind turbines (HAWTs) […]
The London 2012 Olympic Games are being heralded as the “greenest games ever,” and one of the latest green boosts to the game has come to the centre of the Games, Olympic Park, home to eight Olympic venues, including the Olympic Stadium, Aquatics Centre, and Velodrome, and now seven … [continued]
Keele University recently had a new “flat pack” wind turbine installed on its campus. It is intended to address the problems that wind turbine setups have in urban areas. McCamley UK installed the turbine, which is the first of that product line to be installed in the UK, but previously, … [continued]
Chicago’s the “Windy City,” but EWP’s betting that, sited atop Boston high-rises, its vertical-axis wind turbines can make a sizable dent in buildings’ energy costs. […]
Say what? As you can see above, that’s a lamp. It was printing using 3D printing. And its design makes it produce electricity for its LEDs when it spins in the breeze. Nice? I thought so, too. The lamp was created by Margot Krasojevic. Here are more details from Archello: … [continued]
Some more top cleantech news from the past day or so. Solar 1. We’ve written about the large solar boat known as Planetsolar many times in the past. Our good old friend Tim Hurst of Live Oak Media delved into the boats features in good depth in a recent … [continued]
SeaTwirl has created a vertical axis wind turbine (VAWT) that is both direct-drive and stores energy using seawater. It also uses water as a bearing, which has the advantage of low friction. The generator is of the permanent magnet type. This means that it partially utilizes magnets (magnetic materials … [continued]
A company introduced a customizable VAWT called the WindSail.
OK, one more roundup post here — following up on my roundups of 10 new cleantech projects, 10 new cleantech consumer products, and 7 green jobs stories roundups, this one is on 10 new cleantech technologies in the works or just out. Zep Solar recently released an innovative mounting system for … [continued]
Wind energy is growing in use across the U.S., both small and large wind turbines are getting installed at record rates. And the trend is similar across the world. A new report by Transparency Market Research, “Global Wind Energy & Wind Turbine Market (2011 – 2016),” finds that there’s been a Compound Average Growth … [continued]
