Frenette's heater

[hartiberlin]

Hi Dave,
would be nice of you,if you could upload a few pics in a ZIP archive
over here.
It could be, that with oil instead of water the efficiency of the Griggs
pump principle could rise and that Frenette has just seen this
with his heater version.

Many thanks and good luck.

In my researches I found this excellent site giving it a through check unfortunately, the conclusion is still up in the air...

Hello Chris Gupta,
the Frenette heater idea has become a flop !
The "vision",a cheap heater construction with a cheap heat production, did interest
me so ,as consequence,I phoned to the US to different people which has been
directly involved with the first prototypes and marketing steps !

I know also about the actual trial by the "fuelless-power"-people !

But:I never built a physical friction heater model !

My tip/link: try to reach the inventors like Frenette,McMurtry directly !

Hi Mike

Sure. I'll send a couple pics, but I ran into a warpage problem while building the unit, and set it aside. I think the Greggs hydrosonic device is a better option. Have a good day.

You can view the Griggs unit I built in the news section of this site.

If we develop cars that run on permanent magnet motors/electric motors in the future, they will need an efficient heater, since permanent magnet motors don't produce useable excess heat like a gas engine does to heat the interior of the vehicle.
