TOKYO, March 12, 2015 (MHI PR) — Mitsubishi Heavy Industries, Ltd. (MHI) has conducted ground demonstration testing of “wireless power transmission,” a new technology presently under development to serve as the core technology of the space solar power systems (SSPS) that are expected to be the power generation systems of the future. With successful completion of the test at the company’s Kobe Shipyard & Machinery Works, MHI has now verified the viability of long-distance wireless power transmission.

In the ground demonstration test, 10 kilowatts (kW) of power was sent from a transmitting unit by microwave. The reception of power was confirmed at a receiver unit located at a distance of 500 meters (m) away by the illumination of LED lights, using part of power transmitted. The transmission distance and power load mark new milestones in Japan with respect to length and volume of wireless power transmission. The testing also confirmed the performance of the advanced control system technology used to regulate the direction of the microwave beam so that it does not veer from the targeted receiver unit.
