The permanent magnet starter motor gets its power from the same place any other electric starter gets its power from: the vehicle's battery. It doesn't magically create energy from the molecules of the magnets. Also, I don't think it's a true statement that it's more efficient. As far as I know, PM starters are used because of their light weight and high torque, not because they're efficient.
Just so we're comparing apples and apples, lets look at the equivalent starters produced by Sky-Tec, the leading manufacturer of starter for reciprocating Lycoming aircraft engines. Sky-Tec offers nearly identical starters in both wound-field and permanent magnet versions. Check out the link below. Compare the HT and PM/LS models. The 12 volt versions are rated at the identical horsepower while drawing the same current. With the 24 volt versions, the PM starter has a bit more horsepower (10 percent), but it draws a LOT more current (48 percent!). Conclusion: the permanent magnet starter is no more efficient than an equivalent wound-field starter.
Teddy, it's time for you to come clean. How much money do you have invested in Joe Newman's "Energy Machine"? I know you've claimed otherwise in the past, but there's no way you would continue down this path unless you have some skin in the game.

The soil is a rich dark brown and is well looked after. unlike some areas in the midlands it is also fairly flat, broken only by hedgerows and the occasional valley and brook. A copse of wildbreaking silver birch and oak trees surround the top si
