Some people expect these magnetic rectifiers to output pure DC and that was 
definitely not the case.  The output was mostly DC with a horrendous amount 
of AC "hum" riding on top.  This was perfectly acceptable for operating big 
DC motors, etc., but this isn't something you are going to use in your 
hi-fi home equipment!  I would expect this type of rectifier to be 
incredibly robust and impervious to voltage spikes.  The new neodymium 
magnets would probably work very well as a magnetic field "bias" source.  I 
see these rectifiers as being very useful to coilers who want to use DC to 
operate their coils - Tesla coil operation is very hard on semiconductor 
diodes, and I doubt that these could ever be blown in operation.
