Homopolar Generators (N-Machine) by Bruce de Palma

[Magluvin]

I had a discussion of this elsewhere and thought of aluminum disks. I wonder if the voltage would be higher due to less resistance than copper.  But then maybe a copper ring to the outside for commutator as AL. would prob not be good there. Off topic for some, hard drive disks, are the coated with platinum? Those may be great for hho.

Being not many have delved into these devices, I would like to consider some facts that may not be true. Maybe the magnets can spin and the disk stay still. This would be a great advantage. It is very possible the very simple to be discouraged. That said, if I take my pulse motor coils and mount them to my rotor magnets, add a commutator and brushes, will it generate power if it spins? If the answer is no, then I would like to see some facts on that. Or come up with my own. =]
Is it possible that suppressive actions on this go all the way back to Faraday? Could it be that the paradox does not exist? If we had 10 of these in series, would the voltage add up to a very readily usable supply?
My Great Grand Father, With ties to Westinghouse AND posibly Tesla had 2 motors connected at the shaft and all wires went to a box with a switch, give it a spin and it never stops accelerating. The switch would have to be thrown.  My Grand Father told me of this many times. GGF was approached and threatened due to showings all over town, about 60 miles from Pitt. where Westinghouse and Tesla had done some work. GF said that he tossed the box and that was that. Later when GF, who was young when this all happened and did not realize the value of such, searched for that box, but could never find. But maybe GGF was as clever as Tesla. Maybe one of those motors was just internally different, or both.

Just food for thought.

Anyway, Im glad there are some here whom are willing to talk about this, and I am willing to hang in if you are. =]

Some info about Tesla seems to indicate that it might, but that is not what I'm concerned about.

If  the machine can put out thousands of amps at two or three volts, driven by a comparatively small motor, that hi-amp lo-volt output can be directed to a separating electrolyser for H2 production, 24/7.

H2 has more potential uses than low voltage, in my applications

uh? yeah, or there's that thing Tesla patenteded on November 2, 1897,
for some other applications I can think of.

Good points.  Rotational dynamics must be tested in every embodiment:  Fixed mag, rotating mag, co-rotating mag and disk, counter rotating...  These differing configs will benefit from the simplicity of permags.

As fer resistance, I thought Al was a bit more resistive than Cu.

For economy's sake, I will laminate my 26 ga Cu to heavier Al and balance it.  I do not intend to intentionally electrically bond the Cu to the Al plate, at least at first.  I will use hi-dielectric epoxy and much pressure for the bond.

Too bad Gramps canned the motor.   Mebbe it's lore, but if it's real, then that just fuels the passion here.

I still think gravity comes into play in some measure.   To that end, I wanna run it on a vertical axis.

I correct myself, I meant to say as you did.  Al has more res than copper.  =]
Sorry.
Gf had more experience in mechanical vs GGF
GGF built radio transmitters, motors generators some of the first combustion engines of the time. In fact the first ones only had a cam on the exhaust valve and the intake was just spring and vacuum/pressure activated. And due to the amount of coal mining in the area, he even tried coal dust as fuel. He invented a special valve for the air brake on trains that he had a deal with Westinghouse that enabled the brakes to be applied more than once in a short period of time. Before that there had been many accidents with trains due to failure to be able to stop properly.
Where we are from, Ellwood city PA there was a park back then called Rock Point, that had ordered a merry go round from Switzerland, the first in the US, and GGF contracted to make the horses go up and down, of which he did and it was another first.
But since my GF told me of the 2 motors, it got me interested in perpetulal motion in 7th grade. I became involved in electronics even earlier but the gravity pulled me in. I learned a lot from it all.
Now Im here. It is very sentimental to me.

ah, so that's what the 'don't ask, don't tell' fuss was all about.
