RE: Solar power back up batteries are best found by thinking outside the box, The lead acid box that is....
how are the satellites powered, solar power? Satellites last longer than 30 years?

Mostly solar on the long term units.
Voyager 1 and 2 are over four decades outbound and have left the Solar System, and are still reporting today.

holy cow and they're powered by what?
Solar, but as they leave the solar system that will become harder! Even atomic needs to be refueled eventually.
:)>I didn't know they had good enough solar 40 years ago to power things.
Yes solar is not new. More efficient now, but not new.
An Ion drive, with breeder reactor power, and a scoop for fuel collection would make a good star ship.
:)>ok..I suppose you're going to start building a star ship next.
I sure would like to! We could do it with what we have now. THAT would be Fun!
:)>we could do it now? then someone somewhere is working on one right?
