Using microwaves, scientists delivered 10 kilowatts across a 1,640-foot gap. The energy, shot through the air, was delivered with pinpoint accuracy, captured by a small receiver -- the successful transmission signaled by an LED light.

The gap was relatively small, compared to the distance between low Earth orbit and the planet's surface. The electricity received was just enough to power a small electric water-boiling kettle, but scientists say the demonstration promises the possibility of bigger and better feats.
