The Rotoverter is an overunity (“free energy”) generator invented by Hector D Perez Torres. I have not built one or seen it in action, so I do not know for sure that it works as well as people claim. However, I am planning to build one in the future.
Here is an excerpt from RexResearch.com about the Rotoverter:
