SSPS envisages generation of solar power on a geostationary satellite at 36,000km above the earth. The generated power will be transmitted to earth wirelessly through microwave/laser beams.
MHI’s testing of the technology at the company’s Kobe Shipyard & Machinery Works, has validated the viability of long-distance wireless power transmission.
MHI sent a 10kW of power from a transmitting unit by microwave to a receiver unit placed at a distance of 500m away. Illumination of LED lights at the receiver point confirmed of the receipt of power.
The testing also validated the advanced control system’s performance to ensure that the microwave beam reaches the targeted receiver unit without deviations.
The test has been carried out as part of an agreement signed with Japan Space Systems (JSS), the developer of SSPS. JSS has been appointed by the Japanese Ministry of Economy, Trade and Industry for the 2012 Solar Power Wireless Transmission Technology Development Project.
The wireless transmission over long distances will facilitate supply of power to remote locations and will also enable power transmission from offshore wind turbines to onshore.
