Space Based Solar Power is an actually viable idea. I am in debate in my high school and we have a good 500 pages of evidence just on SBSP, it is a real idea and can work.
Whats with all the debaters playing minecraft? Every tournament there are three people huddled in a corner searching for diamonds..
On topic: Space Based Solar Power is actually one of the more feasible forms of alternative energy. I think its addition in IC2 would be more than acceptable, but it has to be done well. But with the height limit being raised you could just make it a solar panel that has increased efficiency at higher elevation. It would make it more on par with the other forms of energy in IC2 currently.
