New dimension for solar energy: Innovative 3-D designs more than double the solar power generated per area

Posted: 27 Mar 2012 06:46 AM PDT

Intensive research around the world has focused on improving the performance of solar photovoltaic cells and bringing down their cost. But very little attention has been paid to the best ways of arranging those cells, which are typically placed flat on a rooftop or other surface, or sometimes attached to motorized structures that keep the cells pointed toward the sun as it crosses the sky. Now, a team of researchers has come up with a very different approach: building cubes or towers that extend the solar cells upward in three-dimensional configurations.

Nuclear power plants can produce hydrogen to fuel the 'hydrogen economy'

Posted: 26 Mar 2012 08:25 AM PDT

The long-sought technology for enabling the fabled "hydrogen economy" — an era based on hydrogen fuel that replaces gasoline, diesel and other fossil fuels, easing concerns about foreign oil and air pollution — has been available for decades and could begin commercial production of hydrogen in this decade, a scientist has reported.
