BTW in my late night verbiage I said another stupid thing. Hanging

another

motor/alternator on the engine is just that.  Redundant generator unless

you

have something electrical you want to power. Charge the battery, and

then

drain the battery motoring one unit again is a net loss situation. NG.
Obviously to make a little turbocompound unit the second generator needs

to

be run by the turbo.

Funny I feel comfortable with electric mechanical motors or generators

but

not for oil and water pumps, in airplanes.  Call me silly.

One question for Vance. You mentioned homopolar motors once. I was

curious

if you had ever meet Bruce DePalma or seen any of his work? For those of

you

who don't know of him, Bruce was a very controversial physicist who

lectured

at MIT and had many theories that didn't agree with Newton's laws of
physics. I as well as Bruce hesitate to say the words free energy.

Actually

it is perhaps 'other energy' source. Before he died he made some

interesting

(but heavy) motors.

Doug in Japan

Well it is easy to check the alternators with no electrical load. Just

measure

the HP it takes to motor them at 10,000 RPM. I think you will find it

significant.

Most of them have a built in centrifugal air pump for cooling.

The one pound was arbitrary. It is some finite number but I would need
some details to estimate it.

I'll buy over 90% but call me skeptical about high 90's.

I have to admit that I am not familiar with the work of Bruce DePalma. My
exposure to homo polar alternators was for small, quick start power
generation systems driven by monopropellant (ie hydrazine, hydrogen peroxide
etc). Small, ultra high rpm turbines with direct drive PM alternators. The
rotor was a virtually homogenous cylinder to withstand the hi "G"
environment.
I owned a 1924 Buick which had a direct drive starter/generator, and of
course the Model T had flywheel magnets. I think both Revmaster and Monnet
integrate an alternator into the flywheel for VW conversions. But direct
cranking
is probably limited to some Hybrids. - Vance
