Question of the Week: Electronics & Computers
Will Rectennas Reduce Our Need for Batteries?
Rectennas act a bit like your car antenna. Instead of picking up radio waves, however, the tiny optical devices absorb light and convert it into power. The rectenna featured in today’s top story, generated half a nanowatt – a small amount of power that its inventors hope to increase.
