kitzilla writes: "Two research groups working independently have come up with what they say are cheap processes for growing nanowires to be used with solar cells. The "hairy" cells provide a direct path for electrons collected at the panel face to reach an electrode, something which has the potential to dramatically improve system efficiency. To be marketed by Hirsute Solar, no doubt."
"The fundamental principle of science, the definition almost, is this: the
sole test of the validity of any idea is experiment."
