I think that Greg Leyh posted this 2 to 3 months ago after measuring
his "Electrium" coil's I/V curves. Nobody has since commented on his
results.

see:	www.lod-dot-org and follow the links down to the electrium
stats/pictures.

check here:	http://www.lod-dot-org/electrum/electrumstatus.html but
don't miss his main page's links.
