Free Energy?

[narilyte]

Been seeing more and more stuff on "Magnetic Motors". That is, motors/engines/whatever you want to call them that has a central output shaft (not unlike a motor or engine, surprise surprise) that is continuously spun based on magnets continuously attracting/repelling each other with no outside energy input. It is, essentially, free energy. They will supposedly never stop spinning. Hook one of these devices up to an appropriately sized power generator and it will continue to generate power indefinitely.

Part of me says that there's no such thing as free energy, but I can't help but wonder about these things.

Is it possible? Could these "Magnetic Motors" really exist?
