The End of Power Cables? Plastic Power Sheet!
University of Tokyo researchers have created a sheet of plastic one millimeter thick that can deliver 40 watts of power to objects on it -- or EVEN NEAR IT! This fish bowl is sitting on the sheet, and the light inside is powered by it through the glass and water. The secret sauce for the plastic is pentacene, which is an organic molecule with controllable electrical conductivity. When this technology hits the market (in about five years), you'll be able to buy a desk that powers or charges any object sitting on it.

how come the fish doesn't get electrocuted?
That thing at the bottom of the glass is a power "receiver" that can contain the current and pass it to the LED. Think of it like an electric toothbrush charger (it's actually probably a similar principle but with some enhancements), you can't electrocute yourself by sticking your finger in there because you're just exposed to magnetic waves and not electricity directly.
Good question. Anyone have any ideas? -Mike
It's basically an AC/DC adapter, and functions like a transformer, like anonymous said.
