In anyone here familiar with the work of Phillip Kanarev? A Russian physics professor and inventor who is more than a bit of an iconoclast.
http://guns.connect.fi/innoplaza/energy/story/Kanarev/ My interest is that he supports the work of a Russian engineer who claims that centrifugal force can be overunity as a power source ( Linevich). Both of these men claim to have built working models of off balance devices - that are in some cases self running. The story is that Linevich observed that a malfunctioning pump in a Greenhouse generated more mechanical energy than could be accounted for relative to its input power.
