Dirac Belt Trick Mechanism cleverly avoids twisting wire
« on: March 17, 2021, 04:45:46 pm »
This is an interesting video I ran across. A cube is turned continuously, but the string attached to it doesn't get twisted.

I wonder if you could somehow use that principle to construct a homopolar disc generator or motor that doesn't need slip rings?

Hmm, perhaps.  But is the solution worse than the problem -- how are you going to get all that current out?  Surely not through cables, the amount of flex requires a lot of slack and discourages large amounts of it. :-//
