What it's not: A test sample of Eggo's new cotton candy-flavored waffles.
What it is: A grid of microscopic, carbon nanotubes, which Jud Ready and other researchers at Georgia Tech Research Institute hope photovoltaic manufacturers can one day use to build up instead of out. These tiny towers (about 32 billion could fit in the period at the end of this sentence) could substantially increase sun-harvesting surface area on the tops of silicon wafers, making it possible to do more with less. Notice we said “wafers” and not “waffles.” Put the butter and Aunt Jemima away.
