022 The Strange Engine - An Easy Build Engine

[limpotamalgu]

thank you very much bro. you are so helpful for the world.

Idea. Make two such engines. One is bigger than the other. The larger one should be filled with water, the smaller one with methanol. Place the membrane with the mass on top of the smaller motor. The smaller motor should be placed inside the larger motor and the top should be closed. Thus, although the two motors are in one, they are actually coaxially opposite, and there is a membrane between them. In this way, the internal motor runs with the waste heat of the external motor. In essence, we use the heat twice, once with water and then with methanol. Overall, we get a steam engine that operates at atmospheric pressure with a temperature difference of 35 degrees Celsius. What do you think, could it be good?

That engine is used as the power generator in water boilers, its a atmospheric stirling engine the mass needs to be a magnet to generate power with a coil, they size the diaphram to match the 50hz mains

I wonder if the regenerator would work better with metal pellets or coarse steel wool.

I made one too, I posted a bunch of shorts a while back on it. I call it state change thermoacoustic engine. The chamber pressure modulates the boiling point and condensation point causing rapid oscillations in boiling and condensing, so as the load is free to move up, the water is free to boil, but when the load reaches TDC the chamber pressure starts to build, at a certain point, the chamber pressure is too high for the liquid to boil so it condenses and continues to drop until you get to BDC.

As a side note, it's quite efficient, this is probably just about as efficient as it's possible to get as you don't have a displacer to move around in the chamber. Bet it's damn near 70% efficient.

annnd with the ceramic its got a convenient handle for carrying hahaha so cool

[sierraecho]

Hypothetically speaking which method of energy conversion would be more efficient for this engine and why. Of course it is a linear generator.
1. Magnets moving through coil (or a coil moving through magnets, like in a speaker)
2. Piezoelectric crystal which gets deformed.

Come on now get some damn 55-gallon drums out there and get busy, , let's let's bake a big one now😂😂❤

Attila Blade coated a speaker spider with silicone rubber. It works great as a diaphragm.

I wonder if this could be scaled up with some steel drums and maybe cool the top one down with some running creek water so it stays rather cool and heat the bottom with a solar heater (methanol) or rocket stove (water). Could possibly produce quite a bit of power? Biggest issue I can see is a robust enough membrane.
I’d love to hear anyone’s thoughts on this.

[awesomewater]

could it be used to make a refrigerator ? that would cut down on some bills . great stuff by the way .

[reypolice]

If you do this with solid dry ice/ CO2 no fear of flammability. Too little or too much dry ice may be key to what is needed for a particular size container.
But once sealed, very little heat will be needed. Possibly better than water.

[mainegardenguy]

I'd love to see a build on a generator that can be placed on or near a wood burning stove.

[neilmcdonaldii]

LOL!! Fish tank I have ants that produce that stuff for free.... Now only if I could convince them to share it while also convincing not to eat my crops.

[gerryplayz]

Hi Robert, you had a video with something that looked like ceramic balls that reacted with water, can you tell me what they were? I went through all of them but can't find the one.

Did anyone catch how the 12 mm nut was attached to the balloon diaphragm?
