Photovoltaic cells offer that capability today, but now researchers claim to have found a way to improve the efficiency of that process greatly, using a device called a "rectenna." This combines the functions of an antenna and a rectifier diode to convert light directly into direct current.

A new design of rectenna that uses carbon nanotubes with tiny rectifiers fabricated into them could form the basis for a more efficie...
