It Can Save The World - The Simple Genius of Hot Air aka Stirling Engines

That's right theses can produces electricity,use antifreeze or Superfluids
I know I'm a Genius !🙈🙉🙊 Can last 80 years , Kool without Refills.

You really should have oiled all moving parts while being assembled . It would run much more smoothly afterwards .

Quiet engines. 50% of Americans will never go for it. That many egos require noise to feel OK. Those same people will resist the switch to electric vehicles for the same reason - even after range anxiety is solved.

Not even a drop of oil upon assembly??? Why..

1) As I understand, modern Striling applications use pressurized inert gases, not just air. Of course, hermetization issues should be solved.
2) electrical (hybrid) schemes allow to use Sterling in cars

Hot Air engine!

Technically, you could put a Sterling engine in a car.
You could - with enough clever engineering - pair a sterling engine with a CVT and drive around.

Great info, well explained!!

I loved your explanation,
Bro is possible do this with a volatile liquid? And use a water to refrigerate?

Yeah why are we not using exhaust to charge the battery? Turbos are bad

My brain immediately thinks what would happen if u use a powerful Tesla battery as your "heat source" for ur Stirling engine

To get better power modulation, the system could be combined with a mechanical KERS. So it can take up excess energy when getting off the gas pedal and supplying additional energy when flooring the gas pedal. However, this also wouldn't solve the problem of getting the system initially started.

Could this be powered by Geothermal energy? If so we could dig for underground power plants that could make massive amounts of clean energy.

can't save the worlds with one of the most wildly inefficient engines, there's such huge amounts of powerloss in sterling engines, and they produce a miniscule amount of torque, making them essentially useless.

Another really cool and educational video. Many thanks.

Iv'e been thinking about using mirrors to focus sunlight into one of those. Would you try it and gives some insight into that?

I think the big missing reason on why these engines are not used is indeed their low power to weight ratio. But even with stationary applications, Stirlings tend to also be much larger than their equivalent power ICE counterparts, which in turn drives up costs. Those engines seem to rev quite fast, but the missing bit is the output torque, which will be very low for its size because air (and other gases) are very compressible, meaning that they don't push very hard on the pistons compared to steam or the far hotter air-fuel mix in ICE.

Wouldn't a potentially great application of these engines be to complement an ICE engine to propel a vehicle and charge a battery?

I could imagine, though I'm sure the real implementation is hideously complex, wouldn't having a Stirling engine heated with the waste heat from an ICE and a clutch to couple it to the drive train in order to improve highway efficiency?

Or going further, and perhaps too complex or heavy: but a Stirling paired to a hybrid vehicle which charges the battery or powers the drive train depending on conditions?

I feel like there has to be a startup working on this somewhere.
