Absorbing All the Light and its Energy
November 10, 2011 | Leave a Comment
NASA engineers have developed a super black material that absorbs light across multiple wavelength bands. The material absorbs on average more than 99 percent of the ultraviolet, visible, infrared, and far-infrared light that hits it — a development that promises to open new frontiers in space technology. It also has implication for those seeking to […]

The Best Thermal Solar Panel Might Be the Cheapest
September 6, 2011 | 7 Comments
The MSRP is $2749.00 Canadian. One panel per 1000 square feet, more north than Maine’s northern tip. The basic collector is made using recycled soda pop cans. Amazing. This thermal panel works astonishingly well. Note – don’t test the thermal conductivity of an aluminum can with a heat source that can burn skin – the […]

Collecting Solar Heat to Make Electricity
May 10, 2011 | 2 Comments
Rice University researchers are describing a new way to harvest solar energy with a new paper this week in the journal Science. Naomi Halas, Rice’s Stanley C. Moore Professor in Electrical and Computer Engineering, the paper’s lead researcher explains, “We’re merging the optics of nanoscale antennas with the electronics of semiconductors. There’s no practical way […]

Progress in the Solar Cell Two Step Method
February 19, 2009 | 11 Comments
Robert DiMatteo, the CEO of a startup based in Boston named MTPV has a new approach to converting heat into electricity using solar cells could make a technology called thermal photovoltaics more practical. Thermal photovoltaics are solar cells that convert the light that radiates from a hot surface into electricity. The first applications will be […]
