Tesla Pancake Coil
2008-04-08 01:28:00 Thank you, thank you, thank you to all out there helping the cause of alternative energy discussion.We here really enjoy the youtube videos and hope it encourages people to move on from fossil fuel. It has us.We've put together a SSG Bedini wheel and this evening put 2 bearings on an upright block placed on a platform (all wooden) and have a Newman Motor running at least 1000 rpm. remember folks 600 rpm is only 10 cycles a second.So we want more and will get it tested and maybe modify the magnet arrangement beforehand. 5000 - 10,000 would be a nice target. All in the geometry.OK back to the you tube - it's that Tesla coil again.
