^^^Seems like one of those ideas that's better on paper than in practice.

Personally, I think this idea would be suited for space, among other reasons, "the project will meet 15 per cent of Europe's electricity needs by 2050." If we would concentrate our energies (no pun intended) temporarily on space based solar power, we could solve a lot of energy woes without making the next energy leap (hydorgen, etc.). Average solar power per unit area (W/m^2) outside Earth's atmosphere during any given time period is about 136% that of Earth's surface during direct sunlight and is constant.

Although, going to the moon and mars would bring many benefits too.
