The Japanese Space Agency is planning to put prisms up in space by 2030 that will help to concentrate sun light and then the generated solar power will be beamed back to Earth.
This is futuristic thinking typical of the Japanese but very much a viable plan.
What the implications of this might be on the global environment is for scientists to study and understand.
The Japanese are of course very poor when it comes to natural resources, but they have more than made up for that poverty with their abundant human and intellectual resources.
One can only wish God Speed to the Japanese!!!
