Metasurface-based antenna turns ambient radio waves into electric power
https://phys.org/news/2022-02-metasurface-based-antenna-ambient-radio-electric.html
"device, which measured 16 cm by 16 cm... changing the power and frequency of a radio source between 0.7 and 2.0 GHz... ability to harvest 100 microwatts of power from radio waves with an intensity of just 0.4 microwatts per centimeter squared... intensity of the radio waves 100 meters from a cell phone tower... placed a cell phone very close to the antenna during a phone call, and it captured enough energy to power an LED... more practical to harvest energy from cell phone towers"
