Faraday Drum -- Homopolar Generator.

Beyond the boundaries of established science an avalanche of exotic ideas compete for our attention. Experts tell us that these ideas should not be permitted to take up the time of working scientists, and for the most part they are surely correct. But what about the gems in the rubble pile? By what ground-rules might we bring extraordinary new possibilities to light?

Their drum variation of the Faraday Disk is interesting.
They use Neodymium ring magnets, with N outside & S inside (not sure). Plastic cylinders fit inside & the magnets dont touch the axle rod. With this design the electrons are forced along axially (instead of radially in a Faraday Disk). In their 5 magnet design each ring magnet contributes 17 mV at 2000 rpm or 25 mV at 3000 rpm (5 magnets giving 125 mV).

At the end of Exx 005 they propose a drum using 40 ring magnets, but touching (ie no gaps), & ask us to estimate the resultant emf (which will be i reckon at least 47 mV & no more than 94 mV)(my guess is 60 mV)(at 2000 rpm).

The 40 magnets would each contribute say 48 mV giving a total of 1920 mV if they had gaps as wide as each magnet, instead of touching. They would then need a bridging wire at each gap.
And the 40 magnets would each contribute say 17 mV giving a total of 680 mV if they had gaps of say 10mm (using plastic washers)(with bridging wires).
