    White House misses deadline for solar panels By: Darius Dixon June 21, 2011 09:17 AM EDT The official onset of summer signals the Obama administration's unmet deadline to install solar panels at the world's most famous address: 1600 Pennsylvania Ave. Energy Secretary Steven Chu announced in October that after a nearly three-decade hiatus. the White House would once again have a solar water-heating system mounted on its roof, as well as photovoltaic cells. Chu said the panels would be up “by the end of this spring." Spring ended Monday, and the panels aren't there. "The Energy Department remains on the...

    Scientists from the California Institute of Technology (Caltech) have developed a new solar cell that they hope will cost a tiny fraction of current production. The new cells consist of tiny silicon wires that measure a mere 1-micron in diameter. These wires are embedded lengthwise and perpendicular into plastic plates where they convert light into electricity at an exceptional rate of efficiency. Any light that is leftover bounces around inside the wire matrix until it finds another wire that can absorb it, thus nearly all the light is captured and converted into electricity. Professor Harry Atwater at his namesake research...

    Here is what the acolytes of solar power don't want you to know... These are the essentials you need in order to appreciate the absurdity of using solar cell power systems as any kind of sensible alternative. After you read this, ask yourself again how much sense solar power really makes.
