Mitsubishi confirms viability of wireless solar power transmission

Mitsubishi Heavy Industries, Ltd. (MHI) recently carried out a ground demonstration testing of wireless solar power transmission. Unlike the solar tech presently in use, this is a groundbreaking and potentially disruptive technology currently under development. It is expected that space solar power systems (SSPS) will be the power generation systems of the future, thus providing the planet with clean, wireless energy, and perhaps ending the reign of the environmentally and socioeconomically destructive fossil fuel cartels.


With the successful conclusion of this test, which was conducted at Mitsubishi’s Kobe Shipyard and Machinery Works, MHI has confimed that long-distance power transmission has the potential to become a reality. The testing was conducted in agreement with Japan Space Systems, the incorporated foundation which was consigned by the Japanese Ministry of Economy, Trade and Industry to man the 2012 Solar Power Wireless Transmission Technology Development Project.

The wireless power transmission under development for SSPS use is called radio emission technology, and MHI says that, once perfected, it will facilitate wireless transmission of power over unprecedented distances.

During the test, 10 kilowatts (kW) of power was sent over a distance of 500 meters from a transmitting unit to a receiver unit via microwave. Power reception was confirmed by the illumination of the receiver unit’s LED lights. In terms of length and volume of wireless power transmission, the power load and transmission distance involved in this test set new benchmarks in Japan, while confirming the performance of the advanced control system technology used to ensure that the microwave beam does not stray from the targeted receiver unit.

Wireless power transmission technology could eradicate the conventional cable connections presently required to transmit electricity, thus providing electricity to areas where it is difficult or hazardous to install cables. The technology could be applied across verticals and would be ideal for powering electric vehicles, which have yet to catch on in many places due to lack of charging points.

The Space Solar Power System will generate power on a geostationary satellite that is equipped with solar panels and situated 36,000 kilometers above the earth. The power it generates will be transmitted to earth by microwave or laser, while the power received on the earth will be converted to electricity. Since the energy source is unlimited and environmentally friendly, the SSPS is expected to be a permanent solution to the myriad problems associated with fossil fuels and nuclear power.

MHI says that it intends to pursue expanded practical applications of this technology to contribute to social progress, while simultaneously advancing Japanese technology in order to establish Space Solar Power Systems.
