What makes you think that this will ever happen?

The laws of Nature can not be evaded or avoided. Launch costs may come down somewhat, but NEVER enough to make the solar power satellite economical.

        Surely you are right. Solar Power Satellite is a VERY BAD IDEA. (n/t) - David F Mayer - 7/12/2004 9:20:44 AM
