Remember those glass globes with the spinning black and white vanes in them? Well, this is SORT of like that, but on a larger scale.
Connect a set of solar sails so that the solar radiation turns the assembly the way wind turns an anemometer. Build in a coil that generates electricity by using the
earth's magnetosphere as a huge fixed magnet. Use the power generated for a satellite or space station, or microwave the power to earth.

isn't actually powered by light pressure, though opinions differ on what exactly does provide the motive force ... [batou, Apr 21 2009]

//using the earth's magnetosphere as a huge fixed magnet// I agree it is huge, but it is also WEAK and even weaker in space, so don't expect to get much power. |

The structure would need to be so unbelievably Dyson-sphere-level big and would produce such miniscule amounts of energy that it might just be the least efficient generator of all time. [+] |

Wouldn't actually work in high vacuum, but a bun anyway for both a fun idea (who doesn't love radiometers) and the magnificent scope of it ! |

It's actually a little-known fact that the Earth's rotation is
driven by assymetric solar radiometerish forces. |

one of those little known controversies.... |
