Scientists think it is possible to have a solar power plant in space and then use microwaves to transmit the power down to earth. In fact, the Discovery and Science Channels teams up and did something with new technologies like that to "fight global warming" but it would be really tricky and really expensive not to mention the national security aspect of it would be terrible. Imagine is someone sent a missile out into space and knocked one of them out.

If we deflect solar energy towards the Earth (which would otherwise have missed it), aren't we going to make the planet even warmer?

 

It's just microwaves, a lot like radio waves but I see your point.  Instead, compare vibrating the earth just a little bit with a coal plant belching out smoke, C02, etc which just can't be good for the environment can it?

 

Btw, the japanese are planning on launching a sattelite like this, or getting somebody else to launch it, mabey china or the US, but either way, the japanese look to have a really cool geeky way of getting energy in the future.  I think that it could work, I mean, the sun has to be a LOT brighter out in space where you don't have clouds or the atmosphere blocking the sun, so a lot more energy could get to the solar cells up in space.
