Mitsubishi Heavy Industries (MHI) has conducted ground testing of a wireless power transmission technology.

MHI says the tests verify the viability of long-distance wireless power transmission. Tests were conducted at the Kobe Shipyard and Machinery Works in Japan.

In the test, 10 kilowatt (kW) of power was sent from a transmitting unit by microwave to a receiver unit 500 meters (m) away. The transmission distance and power reportedly marked records for Japan in terms of length and power of wireless power transmission.

Mitsubishi says the testing also confirmed the performance of the advanced control system technology that regulates the direction of the microwave beam and keeps it on target.

MHI says that achieving wireless power transmission over long distances will facilitate transmitting power to locations where power cable installation has been difficult or dangerous. The technology also is expected to contribute to transmission of power from offshore wind turbines and possibly wireless transmission of power to electric vehicles.
