Just power your stuff on the cell towers.
New wireless devices need no power supply, can harvest energy from TV towers

Wireless devices and sensors capable of sending and receiving data may soon be able to also harvest the power they need, right from the air, thanks to the radio waves that already emanate from cellphone and TV towers.

The team at UW has developed a technique they call "ambient backscatter", which can let devices use the cellular and TV transmissions already being broadcast around us, reflecting those signals to send and receive their own data to similar devices, without the need for a battery or other power source.

To test the ambient backscatter technology, the researchers set up a small testing network in Seattle, and the devices were able to communicate with each other, as sensors would in a real-world application, even up to 6.5 miles away from a TV tower.
