Friction heater running in my house

[Blargus]

It may be difficult to keep the system together structurally. You are going
to need bearings at each end.

The material is very weak. Can you find a couple of stainless steel
vessels, maybe in one of those cheap kitchen supply shops?

Hm, yes the smaller can is very thin aluminum but the big can I kept because it is quite thick--I'm sure it could support my weight without crushing, can almost support my weight without bending if I try to crush its side. I got it at a chinese grocery store. I'm hoping the thin inner can will not deform? Bearings hmm, that would probably be the best way to go. I was hoping I could get away with putting an "all thread" bolt through the smaller can and then mount a steel spacer that holds the bolt without too much side to side travel in the middle of the bottom of the larger can. No metal on metal if there's oil in there, right? But now that I think about it the top of the larger can probably needs a bearing cause a spacer would be up in the air. I'm trying to strike a balance with seeing if it works versus having absolutely tiny sums to invest . I think given the rpm it probably needs bearings. Thanks for the idea!

Build Detail Question

I watched all your youtube vids on this project and must say I am impressed. I would be interested in you showing how the 3/8" outer rings were made.
Also would like to say a 1HP motor should be using 750 Watts under a 1HP Load so @ 400 Watts your only loading a little over 1/2 horse. Another thing I see as a benefit with this heater is that at 180F all oils are pretty much the same viscosity and that is water like. So if the heater cycles and the oil is still around 180F when she kicks back on it will create less load on the electric motor starting as opposed to starting from a room temperature oil which would be different for each viscosity oil. We use oil viscosity in internal combustion motors for starting and at op. temps its all the same viscosity regardless of oil viscosity.

Hard Drive Disks

This might be a good use for used Hard Drive disks for a smaller diameter build if we could work out a good simple system for implementing them as the disks also have a inner aluminum ring that separates the Hard Drive disks in multiple disk Hard Drives. For the stationary Disks eliminate them in exchange for a square flat panel with a hole at center for drive shaft and stack these with outer spacers with a smaller diameter so they become outer fins. this then eliminates the outer drum which is now replaced with stacks of plates and spacers. This would then transfer heat from the stationary plates to the fins as they are one piece. If one was worried about leaking they could then put the whole unit bolted together inside a box with oil around it also so that same outer oil could act as a heat transfer medium so that the oil could be circulated through a radiator type system to draw off the heat faster

Don't forget that these are probably not magnetic. The interesting thing
about this new heater is the magnetising of the discs

Hmmm.. are you suggesting that its better to use steel for the disks? And also do the disks become magnetic?...interesting if that is the case.

That's what Gabriel has been doing. A big departure from Frenette.
Reminiscent of magnetic vortices, Victor Schauberger and so on.
Also, if the liquid is conductive, could there be shadows of unipolar
generators in some way?

Hello everyone,

I am back from vacation and getting back to work on my heater. I am making some new tools for the next build at the moment.
Also in the market for a new lathe and mill.

I am sure you are in the wrong thread

Hello everyone,

I am back from vacation and getting back to work on my heater. I am making some new tools for the next build at the moment.

I'm very much looking forward to hearing about your further developments, slapstick. Please keep us updated.

Interesting read! This thread has definitely caught my attention.

The design seems similar to a Tesla Turbine. I wonder, does anyone know where to buy a prebuilt hobby size tesla turbine, preferably all aluminum? It could simply be setup to recirc through some type of external heat exchanger.

Any thoughts on this?

Hello,

Yes this is using "some" of the same thinking and design of the Tesla turbine, with some light magnetism's and Frenette concept with my twist to it all.

The heat exchanger will come later to the system, I am working mostly on the core for now.
I am currently making some mod to it and will be posting some pics and a video in the next 48 hours.

Oh ya I skimmed over a couple of those posts regarding magnetism in the heater. I was a little confused as to why the magnets would be added. Is it to try n take advantage of the eddie currents?

Magnets were not added the discs were very lightly magnetized for the eddies but to the point to not make any real load on the motor. It did increase the heat out put by a few degrees after doing this with no extra load to the motor.
The very inner core is getting over the smoke point of the oil witch is at 450F. with still maintaining 600 to 800 watts input depending on ramp up from start to just run. My motor runs at 500 watts with no load, maybe a rotoverter style motor would help this even more. the main point is how much the core load is, 300 to 100 watts of load for 250F to 450F of heat.

Here is the new build

Very nice machine, good work. I would be interested to see a roto verter running this heater. Question: does the thickness of the discs matter? Is thinner better? Thicker? I was thinking about building one with hard drive platters as i have a bunch laying here. Was hold on to them for a tesla turbine but this would be more usefull to me. Some are 3 1/2" and some are 5". I think they would work for the purpose. Just have to come up with a solution for spacers for the outer discs. What type of material are your outer spacers made out of?

Regards!
