Friction heater running in my house

[slapstick]

This friction heater I have built costs me around 5 cents a hour to run @ 14 cents a kilowatt. The inside temp of my house is at 70F day and night, the out side is around 30F to 10F. That would be a delta T between 40F and 60F. My house is around 1250 sq. ft.
Here is my youtube Chanel where I post my videos on it.

Very nice build. This is with many rounded plates from inside as I saw the other vid. What if those non movable plates would be one with those rings so that you're be sure that they're not moving?
Thanks for sharing.

Hi, and thank you

As far as the non moving plates and rings goes they are held down by the lid that has sliding springs on a guide that apply around 50 PSI on the discs and rings and the moving discs are also compressed at the same load so they all stay where they should and nothing bad will happen

I have not shown that part of the heater yet

When I upgrade the new bearing to stop the noise I will take a fast video of it.
I am going to install Swiss High Temp Bearing with a speed rating of 16,000 RPM

Dichronite

If you have Dichronite applied to the bearing, you'll have as close to a friction free bearing as you can get.

How does that compare in terms of other ways of heating your home using electricity (electric furnace, heat pump, etc)?

I am just wondering what the efficiency is, here. I can heat my home using $0, burning wood I pick up behind my home, but is it efficient?

Hi slapstick, looks good.

I sent you a private message.

Yes. What would be good to know is how much electrical power
is going in and how long it takes to heat a known quantity of water
from an initial temperature to the final temperature.

Unless you are using peltier chips to convert heat into electricity
or are generating enough steam to drive a smal turbine, it is hard
to know how you are going to get electrical power for lighting,
washing machines etc.

Would it be possible to produce these friction heating effects with a very small desktop scale model or is a there a limit on how much this could be scaled down? I find the possibility of cavitation generated excess heat fascinating.

I think the best way to measure it would be to put the thing in a tub of water of known volume and temperature. Run it for one hour (or any set amount of time), and measure the kWh consumption. Then, measure the temperature of the water.

BTU = the amount of energy to raise one pound of water one degree F.

There are 3.3 BTUs per Watt.

So, as you see, it could be fairly easy to see what sort of heat it was producing based on what sort of energy it was consuming.

You would want to run this experiment several times, and then average the values obtained.

You should check out the work of Peter Daysh Davey.

Also, John Worrell Keely was deeply involved with cavitation but not
specifically for heating.

Yes it is and I have some of them made up running off of a 12v motor.
There is no cavitation in this system.

Yea I will set something up and test it.

I think the formula actually is.

1KW-H (kilowatt-hour) = 1000 Watt-Hours =3413 BTU
Then 1 watt-Hr = 3413 BTU divided by 1000 = 3.413 BTU
So... bottom line is 1 watt-hour is equal to 3.413 BTU

Hope this helps.

Thank you for the tip m8.
