Stirling engines are having a bit of a revival. What are they, and how do they work? Could they generate our electricity in the future?

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.

They did found a lava lake in Antarctica, so this may work down there!

What if you made a boiler system for the winter month months and put one out side to spin a large alternator off of a truck or something and put a gear box in it. Would that work to make a good amount of electricity?

Diesel its just 20 % efficient not 50. Max efficiency now a days its reached by steam turbines and that @ 40 %.

The principle of generating small amounts of finite improbability by simply hooking the logic circuits of a Bambleweeny 57 Sub-Meson Brain to an atomic vector plotter suspended in a strong Brownian Motion producer (say a nice hot cup of tea) were of course well understood- and such generators were often used to break the ice at parties by making all the molecules in the hostess's undergarments leap simultaneously one foot to the left, in accordance with the Theory of Indeterminacy. - Douglas Adams (if this is the 5000th time for this quote do I win a prize?)

Thank you for interesting video. Micro cogeneration is still in it's infancy, but these things are slowly coming to residential market. In my case I am heating my house with natural gas (from pipes, not bottles), which is 3 times cheaper here, compared to electricity. So I started looking in to electricity generation from heat. Found your video. All is nice, youtube is full of these demonstration units, however I am still to find a working unit at 10kW or so.

paper is not dirty fuel to burn. paper is made of wood, wood is made of trees. the future is electric. the sun provides in one single day more energy that we all need for a full year. we harvest just a little.. because its "expensive"

in the USA a man created a combination between Stirling engine and Air conditioner and Electricity generator - result was Free Energy from Air. This man was killed soon showed this invention to the public...

Bravo, I love it, I add today to my knowledge in mechanics, the counter part of what I was familiar with the electric thermocouples, who can use the differences in temperature to create energy also.

I kind of want to see how much you could generate with a nuclear stirling engine

An entropy device, takes any differential in energy, pressure, temperature. or force, and converts it to motion.. an enthalpy device goes boom.

Something I have always wondered is could you use the same principles used in heatpumo air conditioners to power these. Geothermal heat pumps use the ground as a place to cool things down in the summer or warm them in the winter because underground temperatures are always between 10 and 15 celcius. If you made an alpha type Stirling engine (2 pistons , not in line) and had one under ground and one above would that be a sufficient temperature gradient to make an engine that could be useful.

Probably get a consistent 15 degree difference. Also I uncomfortable with celcius if any of my temperature math is confusing.

You mentioned volcanic heat in Antarctica but it doesn't need to be volcanic. Passive geothermal has just as much potential In Stirlings. Also if you add that dish to the goethermal cooled one in in the summer , and then in winter time cover the above ground piston in cold water. You get and even bigger temperature gradient

I'm pretty sure LB here isn't an engineer, or he'd see potential in a motor that can work from ANY kind of temperature differential. Stick to obsolete weapons.

At 2:22 predicting it runs on expanding gasses coming from the ice as it thaws. Will update after full viewing Okay I was wrong. Its even cooler

Seems to me this could easily be made into a bicycle assist...an insulated cold pack on one side and an insulated hand warmer on the other...attached at the drink holder and to the wheel..by a brake device that would disconnect when you want to slow and/or stop...more or less...lol..need to eliminate the need for heavy liquids...good video

could be used in space or mars were heat could be stored during day and cold of the night to generate electricity/heat to keep rover / greenhouse there warm

Sterling engines don't need much to any resources but heat and a little lubrication. Some people make sterling engines out of old air compressor pumps and pumps from cars, easy because you already have a sturdy cast iron base and the duel pumps are already designed 90 degrees out of revolution from each other. So it is already half made, just a couple modifications, to make it sterling! Also some people have put a valve in the air transfer tube to control the speed! How cool is that! You ask the clerk at menards you want just a air compressor pump, he replies "what?! Don't you want an air compressor ?" You just reply "I'm only obsessed with compressor pumps!" Of course mostly the whole sterling engine idea is extremely captivating! I want to make one myself.
