I figured this would have been talked about before, but i couldn't find it in search. http://www.pureenergysystems.com/news/2004/06/30/6900029PerendevPowerMagneticMotor/ I know its not defying any real laws or anything and theyve been around forever, but im wondering if anyone knows any info on them. What sort of HP/Torque can they produce? What magnitude of stray B field is there? Why are they not researched as much? Limited supply of natural perm-magnets?
