GE Sells Solar to Wind Farms

Jan 20th, 2012 | By John Waller | Category: Top Story

As renewable energy deals ago, General Electric’s announcement this week that it would supply 23 megawatts of solar panels for an Illinois photovoltaic farm was rather small change.

But it’s the type of thin-film solar panels and where the photovoltaic power plant will be built that foreshadows a potentially sizable business opportunity as well as a way to maximize renewable energy production.

Project to use volcano to make power

While Americans celebrated U.S. history on the Fourth of July yesterday, a company in Spain celebrated an historic moment for the solar industry: Torresol’s 19.9 MW concentrating solar power plant became the first ever to generate uninterrupted electricity for 24 hours straight. The plant uses a Power Tower design which features a field of 2,650 [...]

G.E. to Build Largest U.S. Solar Panel Factory

Apr 7th, 2011 | By John Waller | Category: Top Story

In a move that could shake up the American solar industry, General Electric plans to announce on Thursday that it will build the nation’s largest photovoltaic panel factory, with the goal of becoming a major player in the market. The plant, whose location has not been determined, will employ 400 workers and create 600 related jobs, according to G.E. The factory would annually produce solar panels that would generate 400 megawatts of energy, or enough to power 80,000 homes a year.

Brain Waves from Thoughts Used to Move Cursor

Apr 7th, 2011 | By John Waller | Category: Health, Top Story

A cursor on a computer screen can be controlled using thoughts about a range of vowel sounds, research has found. Brain signals have been translated into motion or even pictures before, but the current research showcases a nascent technique called electrocorticography using sensors placed directly on the surface of the brain.

Harvesting Waste Heat Could Boost Photovoltaic Power: Scientific American

Aug 5th, 2010 | By John Waller | Category: Top Story

Engineers at Stanford University may have developed a way to double or triple the efficiency of solar power, in a potential breakthrough that could drop the price of solar-generated electricity to a level more competitive with fossil fuels. Stanford’s Department of Materials Science and Engineering published a paper in the journal Nature Materials yesterday that [...]

New York’s Solar Thermal Plans

Jul 30th, 2010 | By John Waller | Category: Solar Thermal, Top Story

By unveiling a solar heating and cooling programme that could create 25,000 new green jobs, generate US$2.6 billion in revenue and see 2 GW of new solar thermal capacity installed in the state over the next decade, New York has revealed its ambition to become America’s national leader in solar heating and cooling. Thermal storage is also an area that, if effectively solved, would allow for additional advancement of the industry

Major decline in illegal logging

Jul 15th, 2010 | By John Waller | Category: Top Story

Illegal logging in the world’s forests has fallen by nearly a quarter since 2002, according to the most thorough analysis yet.

The London-based thinktank Chatham House says consumer pressure, legal restrictions by importing countries and media attention have all contributed.

Some important forest countries such as Brazil, Cameroon and Indonesia have seen much larger cuts.

Solar plane completes historic 24-hour flight

Jul 13th, 2010 | By John Waller | Category: Solar PV, Top Story

PAYERNE, Switzerland — An experimental solar-powered plane landed safely Thursday after completing its first 24-hour test flight, proving that the aircraft can collect enough energy from the sun during the day to stay aloft all night. Pilot Andre Borschberg eased the Solar Impulse onto the runway at Payerne airfield about 30 miles southwest of the [...]
