Imagine a massive planet spinning in empty vacuum. Can the inhabitants slow down their planet, and generate electricity?
I suspect that they can generate electricity with angular momentum with it, that can be only used to do work with the equivalent angular momentum.
- randomNumber7 2y agoMaybe if we use the moon (and ideally get 2 more) we can build a giant generator.
- drewolbrich 2y agoThe Moon's tidal forces are already slowing down the rotation period of the Earth, which was apparently only 5 hours long about 4.5 billion years ago.
- qnleigh 2y agoYes, but when you consider the combined system of the earth and everything that affects its orbit, angular momentum is conserved.
