I have recently developed something that looks suspiciously like a free energy device, so much so that the physicists on scienceforums.com were initially reluctant to even evaluate it. All the info and links to discussions, the FreeCAD model etc are on my website: http://tomboy-pink.co.uk/SFT 

 Thanks for the zap. I give this to the world for free (which is how it should be) but I certainly appreciate anything offered back.
