Its technology vaporizes germanium sulfide and cools it into 20-30 nanometer layers that, as they're combined, turn into nanoflowers: elegant structures that might look like the carnation on a prom dress or tuxedo, but are really energy storage cells with much more capacity than traditional cells occupying the same area.

ENGADGET: NC State nanoflowers can boost battery and solar cell capacity, make great prom accessories
