Wireless Power Transmission System Transmits Energy Over 148km
Researchers carried out a test of a wireless broadcast of solar power, which was able to transmit Radio Frequency energy of about 20 watts over a distance of up to 148 kilometers.
The ability to broadcast the electricity supply wirelessly from a central hub could make rural base stations cheaper, and safer to operate.
The demonstration of solar-powered wireless power transmission used a solid-state phased array transmitter located on the U.S. island of Maui and receivers located on the island of Hawai.
