Intel snags energy out of thin air, tinfoil hat crowd cowers in the basement

Put on your tinfoil hats, everybody, because Intel has discovered there's enough energy in radio waves to fry an egg. Well, maybe those radio frequency (RF) waves aren't that powerful, but as you can see in the picture above, it's possible to harvest enough energy from a Seattle TV station's broadcast signal (originating 4.1 km away) to run that wireless weather station with an LCD screen.

Besides experimenting with wireless electric power, Intel is also working on ways to soak up energy from body heat, ambient light, waste heat from machinery, and a lot more. Makes sense, because when electric power costs 10 times what it does today, grabbing any source of power will be worth the trouble.
