What is the operating temperature of the magnet?
What is the tensile strength of the magnet material?
Is the bearing assemble water cooled?
How much electrical power can one extract from a 200 HP
2.6 liter engine?

I'm guessing he has no intention of giving anything away before he can
commercialize on it.

I am inclined to think he has not thought it out.
As I recall magnetic materials lose their magnetism when heated.
He it certainly a bit naive about PR.

Paul /Chris,
Mark Nye of NTC suggests that Selenium rare earth magnets
are more suited to high temps. I haven't researched that yet!

Give the guy a break. The only sin he created if he wants to
commericalize an idea is putting his prototype on the net for everyone
to critize it. From my take he is an educator at heart and that is a
good thing. The answer to your last question, and his, is 'It
depends' But you knew that:)
Chris I have to be in Sacramento for a flight physical somewhere between
the 2nd and 4th of October. I`ll buy you lunch and keep my questions
brief. Please send me a contact Tel. number I can reach you at to
fir@gol.com
Thanks

No break.
He could have worded his response in a more gentlemanly manner.
When I put out an idea on the web I back it up with historical research
on the subject. Almost all ideas have been thought of and advances are only
made when materials or other changes occur. When people question my ideas I try
to answer to the best of my knowledge. His snide response indicated to me
he had no idea of the problems involved.
I don't think he has a clue judging by his hair brain
low speed gas turbine scheme.
If you want to see some credible work on the turbine integrated generators
put "small turbine powered generators" in google. A little google goes
a long way. That will lead you to this.

Also Caterpillar has done a lot of work on this subject.
Here are a few examples.
If I can find this stuff anybody can find it.

Paul,
Ok, remind me not to play in the sand box with you:)
Yes you are right on the search. Garrett has posted similar information
in their Power Point presentation when they first introduced the concept
and we have all (on this newsletter) seen it years ago. Maintaining
magnetic flux was thought to be a major challenge. On the other hand if
you physically separate the generator from the turbo and have an air gap
and some insulation in between, then the common shaft is the only item
transferring and or emitting infared heat. Fairly easy to water cool.
BTW, we will have to do the exact same thing mounting a traction drive
to a turbo. The traction drive oil needs to stay a relatively cool at
80 degrees C which I believe is under the Curie point of neodymium
magnets. Magnetic flux is also a factor of time or how long they remain
at a high temp. Our wind turbine high temp. sensor is set so activate a
software routine if the magnets stay at 100 degrees C for more than 4
secs. This then changes the duty cycle and brings the output down.
Clamping and inverting 1 to 4 kWs and controlling and inverting 20kw to
30 kWs is a world of difference in electronic hardware.
Perhaps Nye is just trying to demonstrate something that millions of
developing villages without falling water or wind nearby, but large
quantities of bio-fuel on hand could use. Nice dream IF their is an
abundance of bio fuel. The reality I have seen in Nepal and Africa both
places where I lived BTW, is quite the opposite. Nepal is on rolling
black-outs and fuel both biomass and petro-chemical have become scarce.
At least they learned how to make efficient mud wood stoves which
exhaust gas stream would be lucky to power a pin wheel. Turbo
electrics are for nations that can afford the hardware and fuel even if
the fuel is bio diesel or glycerin.
On his low speed axial turbine illustration, at first glance looks it
looks like it is attached to an asynchronous 3 phase motor. It is a
common trick in low cost hydro applications to use a large motor as a
generator and under size the load. The voltage and to some extent the
generator rpm can be then controlled by the load and a dump load. The
turbine would have to turn about 1450 rpm or slower I believe.
The analogy is a turbo-waste gate or even a Pop up valve except
electrical potential is being wasted or water is being heated.
