Battery Charger

[Word]

Hello, I watched a video on youtube awhile back, it was a man with an electric motor that was hooked up to an alternator. He claimed the electricity used to power the electric motor was far less than what was produced from the alternator. Allowing him to charge multiple batteries, using just the power from the first battery.


The reason im telling you about this video, I would like to see it again or find any information about this subject.. But I cant find the video!

Does anyone here have any information? Thanks !
