I wasn't going to mention this, because it sounds like self-promotion and I
already do too much of that, but this is pretty much the device I used in
THE WHITE ABACUS, except that instead of a black hole I used a magnetically
stabilized metric defect and instead of a Dyson surround I used a hollowed
asteroid, but power was generated by feeding gas into the thing's accretion
disk. No, I didn't really do anything much in the way of calculations,
although it's modelled on a Hawking micro-hole.
