How to make a Stirling engine to generate electricity – easy!

How to make a Stirling engine for generating electricity - easy ! A long time ago, clever heads invented steam engines, the boilers of which often brought trouble to others, they exploded. In addition, these engines are complex and require special maintenance. Therefore, Robert Stirling invented a new kind of engine and patented it in 1816.
How to make a Stirling engine to generate electricity - easy! Stirling engines have the simplest design. It is possible to assemble a low-power engine even without technical knowledge and special equipment. The engine itself runs on any type of fuel: solid, liquid, nuclear, as well as from the sun.
There are different constructs:
ALPHA –
How to make a Stirling engine for generating electricity - easy ! BETA –
 How to make a Stirling engine to generate electricity - easy! GAMMA –
How to make a Stirling engine for generating electricity - easy ! The author of the first option we are considering spoke about the assembly of a demo version, low power. He claims that only a specialist with a serious set of equipment can assemble such an engine, which has a purchasing power. We will check the correctness of this statement.
A titanium bar was chosen to implement the idea. Having leveled the workpiece with a cutter, the author first of all turned the displacer cylinder, in which he drilled a non-through hole with a drill.

How to make a Stirling engine to generate electricity - easy! How to make a Stirling engine to generate electricity - easy!  How to make a Stirling engine to generate electricity - easy! Then I made a hollow displacer piston from the same workpiece, the diameter of which is one millimeter less than the inner bore of the cylinder. This is necessary for the circulation of heated air during the movement of the piston. The hole in it is muffled with a threaded plug and the stem is pressed in. The rod guide is made of bronze.

How to make a Stirling engine to generate electricity - easy!  How to make a Stirling engine to generate electricity - easy! To complete the expansion cylinder, it is necessary to carve a cooling radiator, because this cylinder has two zones, one hot, the other cold. The radiator is made of the same bronze.

How to make a Stirling engine to generate electricity - easy!  How to make a Stirling engine to generate electricity - easy! How to make a Stirling engine to generate electricity - easy! Next, the author proceeded to create a cold loop. Engine power is derived from this cylinder and piston. To simplify the task, the author used a ready-made piston of an inoperative internal combustion engine for aircraft models, with a native connecting rod. I made a cylinder from bronze with a minimum tolerance, the piston, with a fairly easy movement, created tightness when the hole was closed from the opposite side, even without the use of oil.

The crankshaft is milled for balancing with the connecting rods. The flywheel is tightened by the fairing. After assembly, the model was installed on a plank and with the help of an alcohol lamp turned it into working mode.

How to make a Stirling engine to generate electricity - easy!  How to make a Stirling engine to generate electricity - easy! How to make a Stirling engine to generate electricity - easy!  How to make a Stirling engine to generate electricity - easy! complex and unnecessary toy. The generator is not applicable, very low power, if it cranks itself. This is the only manual by which you can understand the principle of operation of the apparatus. The downside is that production without a lathe is not possible.
But the second author claims that the Stirling engine is the easiest engine to repeat. Its engines are sold, and the models themselves are made from waste material that is lying underfoot. Its samples are now capable of generating five volts, 0.6 amperes, and a model is under development with the use of a generator from a car. There are assemblies for two and three working cylinders. Water cooling is applied.
How? But let's get acquainted with the device. I think there will be some craftsmen among the readers who will try to polish this topic.
And so, this is how these models look like
How to make a Stirling engine for generating electricity - easy !  How to make a Stirling engine to generate electricity - easy! Expansion cylinders are made from gas cartridges. They are not afraid of heat and are freely soldered with tin.
How to make a Stirling engine for generating electricity - easy! The piston is wound with metal wool on a bicycle spoke. The cotton wool pistons are fixed to the spoke with tin plates.
How to make a Stirling engine for generating electricity - easy ! How to make a Stirling engine to generate electricity - easy!  How to make a Stirling engine to generate electricity - easy! The cold side of the cylinder is closed by the same bottom of the cylinder, in which there is a hole for connecting to the working cylinder and a hole for the spoke, reinforced, as you think, with a simple ten-ruble coin sealed with tin.
How to make a Stirling engine for generating electricity - easy! And this is how the cooling system on three cylinders in the form of a bath was invented
How to make a Stirling engine to generate electricity - easy! And like this on two cylinders in the form of two cans and a radiator.
How to make a Stirling engine for generating electricity - easy! How to make a Stirling engine for generating electricity - easy ! The bodies are made of plywood, the crankshaft is made of a bar of eight millimeters and bearings.
Well, quite unexpected the solution for the project is the use of medical syringes as working cylinders.
How to make a Stirling engine for generating electricity - easy ! How to make a Stirling engine to generate electricity - easy! They are suitable for this as nothing else. The glass fit is perfect. It is only necessary to cut the syringe itself and its piston and connect it with an intermediate tube to the expansion cylinder.
How to make a Stirling engine to generate electricity - easy! A champagne stopper is inserted into the glass piston, into which a screw fixing is glued.
How to make a Stirling engine for generating electricity - easy! How to make a Stirling engine to generate electricity - easy!  How to make a Stirling engine to generate electricity - easy! The engines operate on gas through injectors made of syringe needles.
How to make a Stirling engine for generating electricity - easy !  How to make a Stirling engine to generate electricity - easy! As we can see: in order to achieve the set goal, it is not necessary to go uphill, you can bypass it without small funds and find fresh ideas.
Dmitry Petrakov's channel
Quite possibly. that in a few decades, an external combustion engine, namely a Stirling engine, can become a source of energy for mechanical movement for a car.
