mind showing the math on this? i really can't see how converting energy twice (ac -> motor -> magnets) can only be a few percent difference in efficiency instead of converting it once (ac -> electric stove).
- varjag 8y agoUsing the electric induction stove and rotating magnets achieve the same effect: alternating magnetic field in a ferrous mass. Electric motors have efficiency up to 95%, and there's no further loss in this system. If you are truly off the grid, you'd come about even using the rotating magnets from mechanical power (say, an ICE) vs converting that power via generator and powering a stove.
