This is more of a engineering question

How could you get a turbine to spin almost infinity. Like for it to spin a alternator or would the magnets on the turbine keep it from spinning non stop and make it freeze between magnets?

@g-m-f a true perpetual motion machine like you said isn't possible. but you might beable to do a setup using a motor, generator, solar panel, and a set of capacitors. the idea on this would be to make it run off itself until the solar panel is generating power again. not really useful but if you want something to screw with people it should do it

Perpetual motion is not possible. There will always be some kind of energy loss. This seems like a nice try: https://m.youtube.com/watch/...

You might get it to spin for a good while with a kickstart and magnet alignment, but as soon as you put a load on the alternator- it will come to a crashing stop
