(OIL PRICE) – In the latest ambitious project to use solar energy in space for powering the earth, a public-private Japanese partnership plans to test as soon as in 2025 if solar power generated in space can be beamed to the earth and converted into electricity.
The Japanese venture is the latest in a series of plans and experiments in recent months to test if solar power converted into microwaves could be beamed to receiving stations on the earth’s surface for large-scale use.

Scientists and science fiction writers have long dreamed of such a solar energy source: harnessing the sun’s energy regardless of weather or the time of day or night. This would overcome the constraints for solar power on earth, where generation can take place only when the sun shines. In addition, microwaves can pass through clouds, so beaming the energy via microwaves to the earth would not pose limits to solar energy due to weather conditions or the time of day.
