Nanotech Solar Collector: Revolutionary, With a Big Catch

"New Solar Collector So Efficient It Works At Night Of course, there's a catch..."

Nanotechnology: an energy collector that picks up visible light and infrared. That catch is a big one, though, as the author points out: Looks like current generated by the nanoantennas is an alternating current - that oscillates ten thousand billion times a second or so. Not exactly compatible with America's 60-cycle-per-second power grid.

Still, this shows promise.
