This is a very good demonstration of the Stirling engine cycle. You can clearly see the expansion and contraction of the gas while inflating and deflating the balloon. Near the end of the video he runs the Stirling hot air engine. He also talks about efficiency and heat lost. Quote from the Principles of a Stirling Hot Air Engine Description:

Tin Can Stirling Engine: How I built a hot air engine almost entirely from junk. I've wanted to build one of these ever since discovering stirling engines in about 2003. Spending the weekend making things in Steveastrouk's workshop gave me the opportunity to mak…

The principle of the Stirling Air Engine differs from that of Sir George Cayley (1807), in which the air is forced through the furnace and exhausted, whereas in Stirling's engine the air works in a closed circuit. It was to it that the inventor devoted most of his attention. A two horse-power engine, built in 1818 for pumping water at an Ayrshire quarry, continued to work for some time ...

 · Robinson Hot Air Engine. I am in the process of making a Robinson Sterling engine with a piston diameter of 39mm and a stroke of 34mm giving me a 40.6CC volume. My displacer cylinder is 69mm internal diameter (stainless Steel). With a ratio of approx 1.6:1 the displacer cylinder has a stroke of 18mm which isn't much and I am restricted to this ...

The displacer cylinders function is simply to help move the air from the 'hot' side to the 'cold' side and vice versa. There are versions of the Stirling that require no displacer cylinder at all. To run, the displacer cylinder must be at least 1.5 times the volume of the power cylinder, but I have run engines that had 10 times the volume.

The Stirling cycle (patented 1816) is a thermodynamic model, this time based exclusively on a gas state. Figure 14.3 presents in a P–V diagram an ideal cycle consisting of four steps, two isocoric (constant volume) heat exchange and two isothermal expansion/compression changes. Initially, the gas is compressed from P 4 to P 1 isothermally by removing the amount of heat Q C.

The hot air engine forming the subject of this paper was constructed by Mr. James Stirling, at the Dundee Foundry, in 1842, for the purpose of driving the machinery there, and was erected in room of the steam engine, by removing the boiler, cylinder, air pump and condenser, and making use of as many of the parts of the steam engine as could be made available, which will …

 · Left: The Stirling hot air engine principle. This is the Alpha configuration; it has the disadvantage that the sealing arrangements for the hot piston have to be able to cope with hot gas; this would not be a major problem …

 · Hot Air Engine Castings Kits (Kits include Drawings) The hot air (Stirling Cycle) engine is a unique style of engine cycle. Basically the engine functions by heating and cooling a captured volume of air. These engines have no intake or exhaust. At one end of the cycle the air is heated which builds pressure forcing the piston up.

Stirling again patented a hot air in 1841 ; the engine is known has the third Stirling engine. His son built the engine in 1842 in a foundry in Dundee. This Dundee engine is at the origin of Stirling's great reputation. This Stirling hot air engine …

 · COMING SOON!!! We are almost ready to introduce a line of Stirling hot air engines that range from toys to higher wattages of power. We are perfecting the Stirling engines in hopes to get an easy to manufacture Stirling model that fits different Fresnel lens sizes.

Stirling engine-based small- and micro-scale biomass CHP systems have been researched for more than a decade. Podesser (1999) reported the laboratory testing results of a biomass Stirling engine with air (nitrogen) as working gas and a shaft power of 3 kW. Biomass Stirling engine CHP systems rated 35 kWe and 70 kWe had been developed and demonstrated by researchers in …

The first Stirling engine I ever saw run was a low-temperature difference Stirling engine was running on a small container of ice cubes. I Couldn't Understand It The room was about 80 degrees F (26 degrees C) and there wasn't any fuel …

The following observations are intended to show, that the "regenerator," as it has been called, but which ought more properly to be termed the "economizer," is based on true principles, and is attended, in practice, with real economy of heat, and consequently of fuel — that Messrs. Stirling's Air Engine, with its economizer, has precedence, in point of date, of Capt. Ericsson's Engine ...

Hot Air Stirling Engine. $ 109.99. Awaken the science kid in you to explore the world with this hot air stirling engine. An external combustion engine powering a LED bulb sounds like the things you find only science nerds have crafted but …

The 'Stirling Hot Air Engine' was the brain-child of the Rev. Robert Stirling, who was an inventor of note as well as being a Minister of the Kirk. He was granted his first patent in 1816 at the age of twenty-six - the same year he was ordained to his first parish in the Church of Scotland.

 · A hot air driven thermoacoustic-Stirling engine is designed, built, and tested. The engine produces about 300 W of acoustic power with a performance of 41% of the Carnot performance at a hot air temperature of 620 °C. The performance of the engine can be improved by suppressing the heat leak down the thermal buffer tube and improving the HHX.

 · Further technological advancements by the Rev. Robert Stirling in 1816 earned him a spot in history as the "inventor" of the hot air or "Stirling" engine. John Ericsson, builder of the ironclad U.S.S. Monitor, developed many …

 · Hot air engines, often called Stirling engines, are among the most interesting and intriguing engines ever to be designed. They run on just about any fuel, from salad oil and hydrogen to solar and geothermal energy.

The Rev. Dr. Robert Stirling is the inventor of the regenerator, that became famous during the 19th century, to be used on hot air engines. Stirling invented also a close-cycle hot-air engine, that was different than what had been done until then. Stirling was born in the year 1790, near Methven, in Perthshire.
