Your Fusion Dollars at Work...

Yes, and Ringworld is the open alternative. We don't have to get greedy and capture all the solar output do we? At least not yet.

The first book I read of my own volition was Inconstant Moon, a collection of short stories by Larry Niven, closely followed by Ringworld and everything else he'd written at the time. I remember Niven stating that mathematically, a Ringworld can be treated as a suspension bridge with no ends.

Fusion reactors don't have to be big, expensive or exude xrays.

Fancy sparkplug not very far from me:

At one time some engineering students determined Ringworld was unstable. They sort of protested at some scifi conventions. Larry Niven simply used that and wrote another book about it. The Ringworld Engineers.
