What Is Islam? Islam is not just another religion. It is the same message preached by Moses, Jesus and Abraham. Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God. It reminds us that since God created us, no one should be worshipped except God alone. It also teaches that God is nothing like a human being or like anything that we can imagine. The concept of God is summarized in the Quran as: { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4) Becoming a Muslim is not turning your back to Jesus. Rather it’s going back to the original teachings of Jesus and obeying him

Thank you, I wanted to fully understand how these work before having a go at building one. This is the best explanation I've found on the web so far. Thank you for all the effort you put into it.

The power derived from these engines is proportional to the temperature difference between the hot cylinder and the cold cylinder, so do everything to make the hot cylinder as hot as possible and the cold cylinder as cold as possible. To do this, the engine should be built to extract as much heat as possible from the hot gas over the flame, and to cool the cold cylinder as much as possible. With the open flame, as pictured, a lot of heat energy is lost in the hot air that does not heat the cylinder but just passes by. This is true of almost all of the working models on You Tube. The overall efficiency could be improved by increasing the heat transfer to the cylinder. One of many solutions would be to put fins on the cylinder, and then shrouds around the outside of the fins. Thus more of the hot air would pass over the metal and transfer a higher percentage of the heat in the air. An addition improvement would be to duct the outcoming air through a heat exchanger to preheat the air before it enters the combustion area. A second improvement would be to improve the transfer of heat from the cold cylinder to the surrounding air by putting fins on the cylinder. An additional improvement would be a ducting system like a stack to help speed up the cool air flowing over the cylinder. For maximum heat transfer, both cylinders should be made of copper, or aluminum. the former having the higher heat conductivity and higher cost, with the latter having a slightly lower conductivity but much lower cost. The principle value of the sterling engine is that it can use fairly low temperature heat, possible waste heat from a different type of heat engine. For example, the hot cylinder could be placed in the exhaust pipe of an gasoline engine, BMW used a similar idea; they added a steam engine to a gasoline engine where that water was heated by the exhaust gas and improved the overall efficiency. Back in the 1900's sterling engines were used to drive pumps and other machines because the heat could be derived from burning firewood. I have seen some of these working. Basically, there was a firebox with the hot cylinder placed in the chimney. If it were used to pump water, some of the water could be used to cool the cold cylinder, or the cold cylinder could be placed in the pump outlet.

Well, it's a demonstration. Although the often these demonstrations, many craftsmen have used as working scheme for the creation of engines. Because of this the Stirling engine is perceived as a toy. And appears myth about the low efficiency of the engine. But these demonstrations are far from effective working options. And an efficient heating. Often, many people do not think about that when heated by fire, a lot of heat escapes with hot gases. After all, their temperature is not lower than the temperature of the hot parts of the engine. Therefore, to increase efficiency, necessary to heat these gases air and fuel which enter the combustor to reduce the amount of fuel.

Dave Alexander correct but I believe the term you were looking for was "surface area" on the outsides of the cylinders. Also the higher thermoconductivity material would only be beneficial for the amount of time needed to initiate operation. After enough time all materials would approach the same temperature given the same fuel source. It may be more beneficial for longer duration to use a lower thermoconductivity material

@pierrearden7720

Based on thermodynamics laws, your explanations are not accurate. There is a limit to differential temperature between hot and cold sources. After this limit, no matter how high the differential temperature is, engine efficiency starts to drop.

Mr. Garvey; The way I read Dave's explanation "as hot as" & "as cold as" possible gave me an impression e.g. to make your hot source to +1,000,000 deg-C and your cold source to -270 deg-C; without considering how much energy you have to spend to get to those extreme temperatures. Sterling engines are one of the most inefficient engines (Eta = 15-30%) that were invented. After decades of research by thousands of academics, no one could make it reach Carnot Cycle efficiency. That was the reason for its extinction. Pierre Arden, PhD, PECaltech 77

Absolutely fabulous. I never knew how these engines worked, let alone the different types. Thanks for your superb production.

the best explanation of stirling engines! thank you very much for this

Beautifully made animation - clear, uncluttered and instructive! Thanks. Now I understand the principles of Stirling engines.

Thank you for the excellent video. I think I finally understand the sterling cycle now. Great animation.

Thank you for a very informative and graphic description of the Stirling Engine.Really enjoyed it!

This really helped me understand the concept behind the Stirling engines, thanks so much and keep up the good work.

Beautifully done and explained video! Thank god for computer modeling and awesome channels like these, I wasn't even aware of the ALPHA Stirling engine until now, that's very clever adding a cold cylinder!

This is an excellent video. this is probably the best video or explanation I've seen to date very well thought out an excellent presentation.

Thank you Mr. Powell, I had only recently learned of the existence of the Stirling Engine while stumbling through U-tube video's. At first glance I had thought of it as just another trinket based upon the idea's of centrifugal forces of the flywheel rotating a crankshaft and manipulating a piston or pistons via connecting rods without a viable source of continuous power. Never the less I was intrigued and began to study into the concept of theory and operation of the Stirling Engine. Yet it has only been a few days since my initial introduction, I found myself in search of a basic simple understandable approach to the Stirling theory of operation. Over the past few days I have seen and read through literature and viewed illustrations that could only impress a Brain Surgeon or possibly a NASA Engineer, far beyond my current level of comprehension. Then I stumble upon your U-Tube video. All I can say is "WOW, I've got it!", It finally makes sense. Yes, after having viewed this very U-tube production of yours, I am comfortable with a very simple basic, rudimentary understanding of the Stirling concept and theory of operation. I thank you very much as I was quickly becoming frustrated as I discovered one scientific explanation after another, each one longer and deeper in depth than the last. None of which clearly demonstrating anything more than Illegible graphs and incomprehensible rhetoric. This video of yours easily explains the Stirling engine in such a way that a layman such as myself would be confident in purchasing one or to attempt to build one for display and to operate for friends and family and proudly explain how and why it works. Knowledge is power, Once again, Thank You

Yes you can get a little more RPM with the beta because of the smaller surface area vs the gamma. ( the more surface area the longer it takes to heat up).However the Gamma could output more power in a shorter time.(depends on what your gonna use it for but thats the pro's and cons :)

Excellent demonstration, thank you.

Good explanation with animation

Nice video, thank you. I'm interested in designing one of these using Solar to heat the hot side. I think to increase efficiency, it would help to put vacuum insulation around the hot side, use ultra black carbon nanotube to coat the hot plate with. Then for the cold side, use composites of super high thermal conducting material, with also also a evaporation unit connected to it, that you can put water, alcohol, or a blend in, to speed up the cooling down process. Everybody wants to use parabolic or Fresnel lenses as the solar concentrators, but honestly a funnel design while less efficient at concentrating the Solar energy to a point, you don't have to move it around as much to adjust for Sun shifting and it spreads the heat across the plate better, because it's more diffuse. If you're using vacuum insulation (double thick wall borosillicate glass) and ultra black/ultra light absorbing material, you don't need or do you want the crazy high temps that a parabolic or fresnel lens can produce anyways. That, and I'm curious if this could drive something like an ultra light weight scooter or the like, and neither parabolic nor fresnel could work for that. What's interesting is that at night time, theoretically, you could reverse the process and use the hot side as the cold side by radiation up to space. For the hot side that is more tricky. Maybe a cheap, light weight, chemical exothermic type reaction? And switch out the evap unit with a vacuum insulated unit to hold that heat in as long as possible.

Thanks. Very good work.

Nice Work Bravo !

That was excellent. Thank you.

All I have to say is the person who invented this idea is a complete genius. 'Robert Stirling'

Great video!

neat little idea: You lay the engine out so its flat like a subaru engine so the cylinders are as far apart from each other. Then you wrap the cold cyninder in copper and run it into a radiotor to keep it super cool. I winder if that would increase efficienty

@bobkoure

2 ай бұрын

By making cylinders plural you mean the alpha? If so, they need to be 90ish degrees apart to allow time for gas expandion / contraction - 180 could be too much. Agreed on a radiator (or fins plus fan driven by the flywheel).

very well explained. thanks

These type of stirling engines or similar, can be designed into a residential or industrial boiler system or combi boiler to run off the same burner or heat source as a boiler and be used to generate power. The power can be used in conjunction with solar panels to charge a lithium ion battery pack as an example.

thank you sir.

Great video, renderings and illustrations! However, it is hard to see (at least for me) if the Alpha config. has 4 strokes - it seems that it only has 2 strokes as do the other two!
