I like machines that show their workings. You can see all the parts of a stirling engine doing their jobs. Stirling engines are simple, but use a principle that may be unfamiliar to many viewers. One thing that you have to remember from your science classes is that gases expand and contract very rapidly indeed, making this sort of engine practical.
Stirling engines are not very powerful nor do they have great power to weight ratios. I know of one annual boat race that takes place in England on a river using stirling engines, and it is somewhat sedate.

If you were to change gears on a car with this type of "Stirling Mechanism" how would you do it? I don't think its possibe.
Ashton Bialek-Kling
You would probably only need to supply the power from the Stirling Engine to a transmission like on a normal car.

14:00 - 14:17 : As he said, no free energy hocus-pocus, but energy that ONLY a Stirling-angine is capable of exctracting efficiently. So, maybe that was a bit more straight-forward than how Lindy said it... Electic Pelltier-Elements do the same, but are very bad compared to the Stirling 4:24 - 4:34 : Human life was nothing worth, compared to profit, that´s why murderous steam-engines won over secure stirling-engines in the beginn of the industrial revolution... Wellcome to Capitalism... Modern Stirling Engines: over 50% fuel efficient, Steam engines efficiency, forget it better... As Lindy said, Stirling is the future for stationary uses of generators and pumps. A firm building just for NASA has Stirlings small as a tiny cola-can, that are 40% fuel-efficient, i guess, high-tech-materials, but the bigger they get, the better they are... a "simple" cola-can-big one should be just 10% efficient, but Nasa has prooven otherwise. A Stirling in your central-heating-camin of your 3-person-family-house is pretty spread in Germany, althought the higher initial investment doesn´t let young families always buy this version of central-heating, but if they do, then they have electricity for free, and sell what they´ll not use, so reducing even heating-fuel-expences. Young families often don´t know of their existence, all they know is "cheap, please cheap", and Stirlings fight also against the competition named "passive homes", that need no heating system at all... State -of-the-art-low-tech-Stirlings are equaly efficient as the most efficient engines ever ( high-tech big diesel engines), much cheaper than their diesel-cousins, simple to build, bigger ( a small disadvantage), and exhaust pure neutral CO2. Diesels exhaust CO2, in combination with large amounts of hundreds other deadly gases, and if you manage reducing or capturing one of them, then, wish you luck by your struggle to reduce or capture the whole rest of them!!!

These would work well in the extremes (Arctic or along the equator and far from traditional electric generators) for recharging batteries, etc. With the use of gears and flywheels the efficiency could be improved greatly for other applications requiring more torque. Combined with solar and wind power, these engines could improve the environment greatly by reducing pollution...which is a step in the right direction if we plan to sustain a comfortable living environment for our home - Earth.
LifeUnder TheMicroscope
I could see the sleight of hand you are ready to dish out before it happens as you get everyone warmed up for the introduction of boiling water vs the ice. This is how simple it is to keep people ignorant to thermodynamics and the cold end that can boil as well. Fusion theory and atomism has ruined simple comprehension and replaced it with a lot of useless words of opinion. "Vroom-vroom" explosions in the combustion engine, that exit while no change in pressure is recorded.

Well considering flying the cooling gas of space the Sterling engine is the natural choice, well at least if you want biological entities to fly the ship. You will have a temperature difference of 200 degree celcius at least, and probably an impulse engine, because regardless what the muppet say you can't fly in vaccua using thrust engines and nor can you fly zero viscosity liquids. It is inertia that make thrust engine works without it in vaccua or zero viscosity liquids they are basicly useless there is no resistance to pressure all you get is flame thrower.

i thought the same immediately. Don't they always say it is so hard to do cooling in space, because it is hard to radiate heat off into nothing. Could we not use the heat generated by engines for trust to warm some gas and use that do generate electricity to power stirling engines? :D

The issue with Stirling engines is Carnot efficiency vs material durability. Carnot efficiency is the upper limit on the efficiency of a heat engine, related to the difference between the highest temperature in the engine and the temperature at which heat is rejected by the engine (I.e., the temperature of the environment). An internal combustion engine burns fuel explosively in a moment and then goes through a cycle, allowing the cylinder to cool down. An external combustion engine like the Stirling has a heater head that stays at the maximum temperature all the time. In the early days of Stirling engines the cast iron heater heads burnt out all the time. Now the heater heads are made out of special high temperature stainless. Getting a lot of heat energy in through a small area without melting anything is still a problem. Modern Stirling engines also use compressed gases like hydrogen and helium to increase heat flow. Tricky to maintain. The engine Lindy has is atmospheric and so limited in heat flow. There are a few on the market as yacht generators, but they are expensive.

Maybe add some aluminium fins to the cold plate so that a moderate breeze will cause more cooling, a bit like a computer heat sink. Something I wonder is that, if you look at the air chamber that has the disk, it's not very deep. I wonder how changing the depth/air volume so there's more or less would affect it. Longer way for the disk to travel, but might make for a longer "stroke" if the temperature differential was great enough.

I once postulated that the temp difference between the dark (minus some 200 degrees) and sunny (scorching) sides of the moon would provide an excellent source of unlimited power via the Stirling engines on a monumental scale. (Same thing for space stations. Behind those solar panels is a shadow area that is near absolute zero. Incredible temp differential.) On earth we have an incredible amount of waste heat extant in the enormous amount of spent nuclear fuel that has to be constantly cooled to prevent environmental harm from heat buildup. Stirling engines should surround every nuke plant to take advantage of that heat source and increase generating capacity by possibly a factor of tens. (Dare I say hundreds?) That heat source is perpetual.

Some decades later, people thought the world would be electrically powered by Peltier elements. Even today some people believe Peltier elements are the future to make electric cars more viable by placing them behind solar panels. It's ridiculous. However, these Peltier elements are very useful for recycling exhaust heat of factory chimneys or cooling towers for example.

So if you made the flywheel with permanent magnets and encased it in or between static coils and added a thermoelectric peltier plate to the top and bottom of the barometric differential chamber powered by the voltage generated by the magnet and coil assembly as it rotates, could you not approach 100% efficiency with the use of superconducting frictionless levitation bearings? Sorry if that's too obvious a question.

Unless you find a naturally occurring heat source near a naturally occurring cold source, the energy required to create the heat differential is always more than the engine could produce.

18:24 100 kilowatts from a stirling engine? 1 kilowatt already requires a stirling engine the size of a combustion engine (that would generate 100 kilowatts).Cooling a combustion engine with a stirling engine would remove more power than it would gain. It would be more efficient to drive a heat pump with any other type of motor than to try to use a stirling engine.

the main advantage of the stirling is that it can harness relatively small temperature gradients but still produce motion. That is good if there is a large volume of materials that have a small temperature difference that normally cant power anything. So for example, a big limitation of geo thermal energy is that most parts of the world only have wells that yield hot water, not super heated steam. But a stirling engine could still use a mere 100C temp difference to generate power.

Ignorance of the laws (of physics) is no excuse. Essentially, a Stirling engine capitalizes on subtle energy differentials, which makes for great toys, but mostly useless in large applications. Internal combustion uses vastly more concentrated stored energy, carried as fuel and burned in efficient engines. Stirling et al depend on environmental differences that aren't always consistent, or able to dissipate temperature changes that thwart the principle the engine relies on. The submarine application suggests silent trolling motors for fishing boats, other places where a larger, heavier unit providing steady but low-power might be utilitarian. As he describes, best uses where heat energy already created from another process would otherwise have to be managed, instead can be tapped for a purpose, without need for further energy consumption.

Would it be possible in a large power station scenario to preserve the optimum efficiency by running arrays of smaller engines rather than one big one? In the same fashion as tesla car batteries are just a large series of smaller units? also would running sterling engines in tandum with turbines work, given that you don't drive turbines off heat per say rather the movement of the steam that the heat causes. Surely they must lose heat as it is in the pipes and such so could efficiency be improved by a more fuller use of the steam?

Another place you could put a passive engine is on a mountain somewhere in the tropics, or on the equator. High up, where its colder, but you put a black foundation beneath the engine. Maybe a few mirrors around to bring sunlight to the areas of the black underneath the engine. Works only during the day, but could have fairly reasonable or even good efficiency.

I feel the presenter is great! As a teenager in Australia I discovered if my school teacher had a passion for which ever subject he was teaching this student, myself included, loved it as well. Then as an adult, now with my own children, I was aghast to realise that success in life or even proficiency in a given field came down to whether she had a teacher who loved what they were teaching! (between the age of 13 -17 I had only 2!). I was mortified!! I realised then that Government funded education in Australia was destined to always pump out mostly illiterate in educated students! Something reported in our media more and more in the last 10years. Think about it! In an era wen class sizes are going up&parents are needing to pay more and more towards something which used to be 100% state funded because even Gvmnts are now forced to cut costs and show as little debt as possible each budget what could be worse?! but a trait that can only be evaluated by another human I.e. whether or not they have a passion4wot they're teaching! Shit, if only they could figure it out in a questionnaire and kick it over to the HR Manage! It's cost only cents. So to my point - if only we had more passionate people like him to teach our youngest. Or great actors who could give the illusion day in and out. If you read ALL of this thank you. 😛

Not a lot of torque in comparison which is a pretty big downside for cars. Also diesel has enormous amounts of potential energy compared with a heat difference, so there's just more energy to harness, weight for weight.
