Does heat produce friction between air molecules producing thrust?

[angushall19]

I had an invention idea for thrust and I was wonering if signifigant heat would produce thrust through air friction.

Friction is a dissipative force, i.e. usually it slows things down. How would this work?

I have heard the idea that you can cool plasma so much that you can contain it. I would figure out a way to contain these molecules and harness their heat power in concentration of the air particles around it.

That's incredibly vague, to the point of not having any physics in it at all.

There have been related real inventions based off this knowledge.

Maybe you can provide some details.

That's true and harnessing the 'power' is already achieved in flourescent light tubes.

The gas inside is in the plasma state.

My idea was to keep its heat level high, but not high enough to melt tunstgen because that is what I would use to contain it.

Hello angus, do you know what plasma is?

 

Plasma is a state of matter where the atoms have (nearly) all lost their outer electron(s) so they are ionised.

I know what it is and I was explaining that there are certain versions(differences) in plasma that change their temperature.

If you created or manipulated sufficient friction, say, inside a piston, you could harness a small fraction of the energy expended and create some thrust.

 

So if you had an energy source for the friction that could not be utilized in any better manner you would have something, however inefficient.

 

Not sure why you would cool plasma to create air friction to create thermal energy. Sounds like you have more thermal energy than you can want to start with.
