GE Weaving Fabric-Covered Wind Turbine Blades

read
Advanced turbine tech could put wind energy on equal footing as fossil fuels

If all goes according to General Electric's plans, the next generation of wind turbine blades will be wrapped in fabric. With a $5.6 million grant from the U.S. Department of Energy’s Advanced Research Projects Agency (ARPA-E) program, GE is developing a new fabric-covered wind turbine blade that the company says will perform just as well as conventional fiberglass blades,......read more

The Big SHFT: Harrison Dillon, Algae Baron

Solazyme takes algae-based biofuel applications beyond renewable energy and into cosmetics, plastics, lubricants, and... ice cream?

Ten years ago, when Harrison Dillon and his partners founded Solazyme in a garage in Palo Alto, CA, their goal was to create clean, renewable diesel fuel from algae. And so they did. But it was clear after a couple of years that they needed to find other applications for algae-based biofuel to make their business fly. Today, the San Francisco-based company's technology is being used to......read more

Graphene super capacitor could make batteries obsolete

Researchers at UCLA have hit upon on a scientific breakthrough that promises to change the way power is stored. The research team has found a way to create a non-toxic, highly efficient super capacitor that can be charged quickly and will hold more electricity than standard batteries. What's more, the team may well have found a way to make that process scale up to mass-production levels. The......read more

Obama Kicks Around an Energy-Producing Soccer Ball

The 'Soccket' ball converts kinetic energy to stored electricity

During President Barack Obama’s weeklong, three-country tour of Africa, he took the time to play some soccer, but with a far-from-ordinary ball. In Tanzania, Obama introduced locals to The Soccket, an energy-generating soccer ball created by recent Harvard alums Jessica Matthews and Julia Silverman. With every kick, the kinetic energy of the ball’s movement is converted into stored......read more

Holy scheizer! The new solar plant measures 27 acres--making it one of the biggest in the world

Germany is adding to its reputation as the world's solar energy leader with the completion of a 27-acre rooftop project near Mannheim. The system, built by Wirsol on the Pfenning Logistics distribution center in Haddesheim, has an installed capacity of 8.1 megawatts, enough to power 1,846 homes. It is Germany’s largest rooftop solar plant and one of the biggest in the world. “We are......read more

Dan Corson's interactive art installation showcases renewable energy tech

"Sonic Bloom" by Seattle artist Dan Corson is an interactive, solar-powered art installation recently erected outside the Pacific Science Center in the Emerald City. The work, commissioned by the Pacific Science Center with support from Seattle City Light’s Green Up Program, features five giant solar flowers that absorb the sun’s energy during the day and illuminate at night via......read more

Invention Harvests Electricity from Background Radiation

read
Device could be used to beam power to remote locations or recharge phones wirelessly

Engineers at Duke University have designed a gadget that captures background radiation and converts it to useable electricity. Operating on the same principle as solar panels that capture light energy, the "metamaterial cells" can harvest microwaves with an efficiency of 36.8 percent -- the same efficiency as modern solar cells. The Daily Mail reports: The development raises exciting......read more

Underwater Kites Harvest Energy From Tidal Currents

Minesto's 'Deep Green' tech starts producing electricity

A kite-like tidal power device off the coast of Northern Ireland has begun producing electricity. The technology, called Deep Green, consists of a hydrodynamic wing and a turbine tethered to the ocean floor. The tether also contains the unit's power and communication cables. As water flows over the wing, the turbine rotates and generates electricity. In an offshore control room, located in the......read more

California Doubled Solar Production in 2013

read
The Golden State continues to lead the country toward a clean energy future

Lydia O'Connor for the Huffington Post: California installed more megawatts of solar energy in 2013 than it did in the last 30 years combined, the California Solar Energy Industries Association reported. "It took California over 30 years to build 1,000 MW of rooftop solar, hitting that landmark in early 2013. Today, California is closing out the year with more than 2,000 MW of rooftop solar......read more
