How can we harness that energy? Is there any engine, heater, battery or other thing that uses it?
Could you explain more? From what I can tell from some very cursory research, I'm guessing that you are asking because the knot represents a different quantum state, but from what I've seen the knots are more stable states which suggests to me that it takes energy to untie them, not to tie them. So I don't think you could use them for energy storage, but I really don't know enough yet. Could you post some sources about them?
@Noduagga Can you give a reference for "quantum knots"?
