Well, Tom Bearden has very recently gotten a patent on this sort of 
device, for what it's worth. You can check it out by looking up patent 
6362718* *on the USPTO server at http://www.uspto.gov/patft/index.html 
<http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=/netahtml/srchnum.htm&r=1&f=G&l=50&s1=%276362718%27.WKU.&OS=PN/6362718&RS=PN/6362718>

However, you won't get the claimed results if you do a simulation of the 
device with FEMM. In the model of magnetism used in FEMM, the permanent 
magnet doesn't/ do/ anything at. In the model of magnetism that FEMM 
uses (i.e. standard E&M theory that has been used to design quite a 
number of successful machines), voltage is only induced by a change in 
flux with respect to time. Since the magnet's flux is DC, it just 
provides an offset for the AC part of the flux that is created by the 
windings. That is, FEMM would predict that the MEG is acting like a 
tranformer, but without any of the unusual properties claimed by the 
inventors.

Now, I knew this topic was going to come up sooner or later, and I don't 
want to spark some sort of flame war. Therefore, I'm declaring martial 
law and pronouncing the MEG officially off-topic. There is already a 
Yahoo group dedicated to the MEG at 
http://groups.yahoo.com/group/MEG_builders/ where discussions about the 
MEG are appropriate.
