It won't work. It won't be done. I think this was first suggested about
2006 (I remember it awhile back, or something very similar). Always
remember "if it sounds too good to be true, it isn't." If that
ever happens to be wrong, so be it, but it generally never is.
Besides, it would not be a good thing to have unlimited energy. That just
would continue the ecological disaster that is transpiring
already.
The real major thing that matters is decreasing our numbers. The chance
of us doing that "willingly" is about as likely as the chance
of solar panels over roads.
I spend very little time thinking about these issues anymore, I think the
inevitable was decided long ago.
