I ran across a concept called the Dyson sphere, where you have a series of interconnected satellites or machinery built in a 360 degree fashion around a star to harness its total energy output. What a cool idea! If I'm not mistaken, I believe Larry Niven wrote on this subject in "Ringworld."
There could be all kinds of stories driven by these star engines.

I've read a couple of the Ringworld books and there was an episode of Star Trek TNG that had a Dyson sphere. If you think about the planetary mass that it takes to create a ringworld, then a Dyson sphere is a ringworld on steroids. I've wondered about gravity on a Dyson sphere. If I remember correctly, the spining motion of a ringworld gives it it's gravity. If the same concept is true in a Dyson sphere, wouldn't there be areas that would have less gravity? Food for thought.

Yes. If I understand it correctly, you'd have more gravity at the equator where the sphere is moving faster to keep up with the rest of it. Less gravity at the poles.
