Wow. Some people might think that software (programming) is impossible to understand, but to me (a programmer) I think that hardware is just insane, how someone can figure out all of the little joints and valves and weights to make something move like that in the physical world is beyond me...
@@watnoudan me too I looked some stuff up but it might be possible to have a engine halfway dipped in water and the other half out and the temp difference be great anuf to turn the engine
The soundwave of te "click"-sound when turning off the lighter, was enough to throw of the coin... Imagine now, how smooth this engine itself was...! Producing less vibrations, than the "click"-sound of a lighter...! ;-)
Stirling engines could possibly be used in charge hybrid cars to drive the generator if the drive train is all electric. A longer start sequence wouldn't be an issue then. A Stirling engine can reach 50% efficiency, a modern diesel about 40% and a petrol engine around 30-35%
check out the Engine of a Ducati Supermono. it has a Pseudo Crank (Counter weight) too to make it run smooth which is not so commen for a 1 cylinder bike.
Heat directly converted to mechanical movement, using air...amazing design! Unfortunately the efficiency of Stirling engines is low but you could use nuclear heat this way to make an atomic jet, car, ship etc.
Actually for heat engines they are the most efficient, their most major problem however is power density. To highlight this issue a Stirling engine that makes say 40 HP might need a cylinder the size of a 55 gallon drum to do it, while a much smaller and lighter IC engine you could entirely fit in a suitcase will easily use 2-3x (Diesel and Gasoline respectively) the fuel to make that same power.
The Sterling Engine only requires a difference in temperature between the chamber and the outside of the machine. You could power it on the top of your computer, though it wouldn't be as strong as one powered by a kerosene candle.
Hi Latheman666, perfect this engine and this magnificent balancing both horizontal and vertical. Excellent job. Congratulations On. Greetings from Brazil Armando Barlotti
Interesting design works well.🎉 So many different types they are definitely making a comeback with the Chinese making a 300kw sterling engine. Some large bore V4 versions are around 80kw.
These are very cool but I am interested in them for their utilitarian value. Have you tested how much torque it can produce, hooked it up to a generator to se how many watts it can produce, or otherwise tried to see how much useful work of some kind it can do?
Does it work with gears or is the static friction too much to overcome for the first cycle? I noticed you mentioned "if the belt breaks" it just goes until it cools off or destroys itself.
@@scotttaylor215 Nope, this is a dual cylinder style sterling engine, with a 'hot' and 'cold' cylinder. Both are required to run, as the engine operates on the principal that the gas will decrease in volume when moved to the cool cylinder and increase in volume when moved to the hot cylinder. There is another kind of sterling engine that has one cylinder, but it still works on the same principal as in this configuration, there is, in addition to the power piston, a large 'displacer' inside the cylinder that is like a piston, but lets the gas around the edges. It's duty is to displace the gas from one side or the other and force it to move between the hot and cold ends of the cylinder. However, in all cases, the sterling engine requires no valves whatsoever. In fact, the interior of the engine, whether one or two cylinder configuration, is one continuous volume that is sealed to the outside.
Incorporate it into a rocket stove to pump hot water produced from the rocket stove. You could circulate hot water through a cement slab to heat or switch the system and cool the home all by using this engine! ; )
that happens when the recording speed gets pretty similar to the engines speed(or in this case half of the engine speed). So the engine is probably doing around 15 rps (if this was recored at 30fps).
it's called the flicker frequency and happens at multiples of 24 ... 24 frames a second being what your eyes and brain can process at one time ... this is why video's make still pictures seem to move ... after 36 frames you wont recognize a change to quality until approximately 72 frames a second .. it happens to be on a logarithmic scale.
0623kaboom the flicker frequency is just about how small the time between two stimulations can be so your eye cant differciat them, thats not same as something feeling smooth, you can have a smooth picture but your eyes will start to hurt over time if the frequency of what ever device your looking at is to low. Alot depends on the person, the age, how strong the change is and many other things. Also the processing speed of your brain can increase temporary, that's what happens when you can feel time "slowing down" in a dangerous situation. But unfortunately this has not much to do with the effect you can see in this video because the effect of something standing still, because it has the same frequency as the recording only happens to cameras not the human eye. For the human eye fast moving stuff just becomes blurry.
Yes it will get cold. If you supply external power to a Sterling engine, it acts as a heat pump, moving heat from one end to another. In fact, do a search for Sterling Cryocooler. Unfortunately, the Sterling engine isn't as efficient as a Rankine cooler for higher temperatures, but for -30 to -40 degrees Celsius, the Rankine coolers aren't effective since there are no refrigerants that boil at low a temperature. At that point, the Sterling engine is quite useful and a single stage cooler is capable of getting to about 73 K (able to liquefy nitrogen, oxygen, argon). You can get colder using a two stage system to get down to 20 K (hydrogen and neon), but there are other methods of getting that cold or colder more efficiently.
your question lacked clarity. if (rotational) force/energy is put in at the Crankshaft, what was the hot side becomes colder. what was the cold side, gets warmer. the affect is just a novelty. this is not an energy efficient way to produce cooling. in part, because there is an Excessive amount of heat produced, Along with the cool. googletranslate
If you took a 50 gallon drum, filled it about half full of pig droppings, ran a tube up to the place where you have the wick, I think you could have an engine run as long as you could get the pig to make your fuel. Might work with cow droppings too.
What is the purpose of the extra (bottom two) linkages connected to the crank shaft? And what is it called? Is it to balance the weight of the lobe in the verticle axis?
do you think this motor set over a bonfire or partially included into the side of the rock ring would be enough to pump air back into the fire to create a hotter fire?
a heat engine will not self-start. but, it would be simple to have an electromagnet mechanism move a drive wheel into place and cause the flywheel to start turning. btw, have you EVER heard of a SELF-starting engine. an engine is NOT a motor. googletranslate
Thanks! That would make a lot of sense, I know a German engineering student that told me they make motors as part of their coursework. I immediately found one for sale on ebay.de, now I will have to save some $$ for it
You can find many different kinds of Stirling engine models on Amazon. Here's the link: www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3Daps&field-keywords=stirling+engine
Hey Paul, I dont find it on ebay either, but I would be very interested in buying it, please could you possibly link me the offer? Would be really nice :)
+Jack Fergusen If all was made of brass it would conduct more heat to the cold part and thus waste it. The best would be to make only the part that is over the flame from a good thermal conductor like brass and the connection between hot and cold part of the displacer from a bad conductor like stainless steel and then the cold part again from a good conductor.
The power to size can be made just as good as IC engines if the operating temperature and pressure is high and proper regeneration of the heat is used.
I don't speak sign language!!! What is the idea of vertical bars, and why is it making that knocking sound? Is your displacer hitting the cylinder head?
@@woowooNeedsFaith okay. you did say 'vertical'. that is part of the vibration DAMPING system. it is Just MASS, going back and forth. energy is lost; damping Consumes energy. googletranslate
Hmm... you shouldn't loose energy just by changing direction of movement. That energy needs to be dissipated somehow, e.g. by making sound or producing heat. If it nothing but balancing masses going back and forth, it should simply transform energy back and forth between potential and kinetic energy - I guess.
putting in a thousands watts, and getting out a few watts to run at top speed? How about hooking up a generator, and a calibrated heat source, and demonstrating the efficiency?
couldn't some one use a lens too focus sunlight onto a Sterling engine too power it? maybe paint the part that the flame heats black so it absorbs better. Idk, just an idea.
You can clearly observe second order harmonic vibrations left to right due to the fact that the connecting rod is not of infinite length and the piston has different values for acceleration and deceleration at both ends (top and bottom or left and right in this case). This effect cannot be counterbalanced that easily. Also, it is also in the vertical plane, but there it is not that important, as the base is rigid enough.
From what I've been able to figure for an engine to be perfectly balanced, one way would be to have opposing pistons that connect to the same point on the crankshaft and go in and out and fire at the same time. One piston would have split connecting rod that overlaps the other's, with exactly the same weight. The connecting rods would drive the crank 180 degrees from each other on opposite sides. All up and down and side to side motion should then exactly be opposed and balanced by the opposing overlapping piston con rod setup. I have a picture on my other computer that I drew.
+sirgallium I thought so as well, but in my head I imagine that a twisting force would be applied because the pistons are not inside eachother, they are offset by the flywheel, so when one goes down and the other up, you will get a twisting force acting with the flywheel as the center? Probably pretty smooth, but not perfectly balanced
