i feel your pain ,
i had to grab some long pants , to go wit my t-shirt this morning...:)

Rotation to Heat?
Moderator: scott
Sweet relief!
Today is the warmest day so far this year. It has warmed up to 44ºF (7ºC) outside at 2pm in the afternoon. My wood furnace has almost shut off since the sun is shining brightly through my south facing windows heating my home to a toasty 77ºF (25ºC) temperature. I guess I don't need that Bessler wheel after all. (That's like the roof that doesn't need fixing because its not raining.) :))
I'm still looking for ideas for the best most simple way to turn rotation into heat.

re: Rotation to Heat?
Hi Jim .. I would say that if you have rotation there are many ways to get heat from it, generally thru mechanical friction of some sorts but solar is another option.
Perhaps if you are also looking for an efficient way to turn that rotation into heat [joules] then a transference system that uses a liquid or gas medium might be best - if that were the way to go then I would probably consider using the rotation to change the pressure in a vessel increasing the pressure & then using a heat exchanger to draw the heat energy out - I guess probably like how a fridge works, cools the interior & gives out heat at the back - another way might be to use the rotation to pump a liquid [say oil] thru pipes into a storage tank on your roof - as the oil flows thru the black pipes its absorbs heat then it is stored in the header tank to back flow at night etc, warming your house - just heat storage & exchanger devices basically.

re: Rotation to Heat?
I think using a generator and electrical resistance heating is the most logical and convenient way of doing it.
If you don't want to hear and feel vibrations from the operations of the wheel it needs to be located some distance away from your living space.
So electrical resistance will probably be the way to go.

Electric generators are never 100% efficient, so maybe I should use some friction device to heat a fluid such as water or oil and then use radiators to transfer the heat into the air of the house. I would expect that the wheel would be located in a wheel room outside some short distance from the home, say in back of a garage or even buried in the back lawn.
With houses (like mine) that are setup using forced air heating, a radiator would replace the furnace and the fluid could be pressurized so as to power an hydraulic motor to turn the forced air blower fan.
With houses (like my mother-in-law's) that are setup using hot water radiant heat the water would be heated in the wheel room and pumped through the radiators.
Since electricity is wanted as part of the output and since an electric generator would be required anyway, it might make sense to just use electricity to heat the house. A home electric generator always needs to be big enough to meet peak demands, so much of the time it is not be used at its maximum. If a house is well insulated and if it has sufficient mass then heating can be postponed during short periods of time so as to provide peak electrical capacity.
----------------
So it looks like there are basically just two methods to turn rotation into heat. One is friction and the other is electrical generation. All other options seem to be just variations of these two. In mild climates (not Michigan) heat pumps would be a third option.

re: Rotation to Heat?
Hi, Jim I'm wondering why. Are you saying you have something?
I've given it some thought and I believe the Carnot Engine is theoretically suppose to be the most efficient type of heat engine there is.

Since heat is everywhere a better option might be to create a cold front that could absorb heat, instead of the traditional other way around.

re: Rotation to Heat?
Rotation to elecrical potential= Yes there are losses but how about rotation to heat.
Is not the conversion nearly 100 percent to heat. I may be wrong here but don't the losses that happen in the generator and transmission lines show up as heat.
I would insulate the wheel room very well and house the generator within the confines of the room to keep the temp high enough to prevent condensation and freezing lubricants in very cold weather.
I would put vents at the top and bottom of the room that could be opened in hot weather. There should be plenty of air flow with the wheel rotating to keep the generator cool.
