OMG, now I've seen it all. I think my knowledge of physics will never be the same

Anyone want to chip in on a Physics 101 book so that we can send it to this guy? Come to think of it, that may be too complicated for him.
There is not an OUNCE of physics on that site! If there was such an 'other' magnetic field it would have been found a long, long time ago. And the excuse that we're using these one-sided magnetic field detecting devices is a poor one at that. An artist with wishfull thinking and nothing else to do perhaps?
Last time I checked Ed Leedskalnin was debunked as a hoaxer. A photo of him was snapped and exists showing him working on one of his structures with a rather complex pulley system and A frames.
