Hi All
One of my sons has asked me about Adam Trombly
http://projectearth.com/articles/21-homopolar-generator
Can anyone fill in a little history on this and the homopolar generator? other than what is on the net.
regards

I thought that homopolar generator innovation belongs to DePalma and Tewari, rather than Trombly. I cannot find any patent in USPTO associated with the name of Trombly.
The Thomas Valone book is pretty comprehensive:

The Rex Research page at
http://www.rexresearch.com/trombly/trombly.htm#trom1
gives more details on the patent application that is definitely in Trombly's name. The Project Earth page at
http://projectearth.com/about/adam-trombly
gives a bio on Trombly.
Incidentally that patent application (presumably it never got to be a patent) shouldn't work because the voltage induced into the rotating disc ought to be countered by the magnet gap rotating with respect to the fixed connection to the brush, that connection passes through the gap. So IMO it works because of something going on in the disc, that just happens to be Fe as it is part of the donut shaped closed magnetic circuit. I would guess that a combination of the homopolar induction and the Hall Effect in the Fe is really what is doing the business. Perhaps that combo has properties that are not fully understood. Maybe a rotation within the B field plus the Hall Effect has a multiplicative property rather than just additive. Anyone on for trying to see if this is true? Doesn't need a machine as complicated as Trombly's. A simple homopolar generator could be made with two interchangeable discs, one of Cu and the other of Fe, then see if they give identical output voltages.
