Powercast transmists RF energy to a receiver module measuring about half the size of a AAA battery.

The transmitter in the lamp sends out a continuous, low RF signal. Anything with either AA or AAA batteries set within its range--and equipped with a Powercast receiver, which is the size of your fingernail--will be continuously charged.”
