Space-based solar power could eventually prove to be an alternative source of electricity for Japan, as the country struggles to find the best energy mix to lessen its dependence on thermal and nuclear power.

The Japan Aerospace Exploration Agency (JAXA) has been conducting studies in the hopes of erecting huge solar panels in space to generate electricity in the near future.

The basic idea is simple: Build a solar power station in geostationary orbit to gather sunlight; convert the energy to solar electricity, and then direct it via microwaves or laser beams to receiving antennas on Earth.

The Space Solar Power System (SSPS) would be able to collect the same amount of solar energy almost 24 hours a day, since it would not be affected by the weather. It could generate five to 10 times more power compared to solar power operations on Earth, JAXA says.

One SSPS with a 2.5 km by 2.3 km panel would have the capacity to generate 1 gigawatt of electricity, the agency says, which is about the same as a nuclear power plant.

Great idea! If it works, and is not too expensive.
