Pressurized alpha stirling engine. Balanced Ross yoke linkage. This is another attempt for making power producing Stirling engine. This model was made for testing fluid power capability. Design costs: 3 monts for design, 4 weeks for welding and mashining, 300$ for laser cutting all sheets. Engine weight is about 30 kg. To All stirling fans: In the project I used an Excel table that can be found at www.sesusa.org/GCS2002.xls . I made the engine in rigid correspondence to the table and I got a calculated power output and RPM. It is a Best Result of the engine, not plans or design.

@gotbread23 years ago Very well done. You are also one of the few persons who does a proper power test and not just let it spin in idle. Props for the power vs rpm curve. 15

@riderericsson2 years ago Very nice work. Maybe this is a stupid question, but why not use a much simpler beta design such as the philips genset from the 1940s? It also produced 200 watts at relatively low internal pressures.

@MakersEase13 years ago Hi - have you calcualted the acutal efficency? You have power in and power out. As you say - it will never be over 50% but i bet it is quite lower id="hidden8" than that. Oh 3kw in and 220w = 7. 3%just watched the video again) still very cool! Thanks sam. ...Expand

@Anvilshock7 years ago If you can get some, try using helium instead of air. It is a lot better in transferring heat and also much lighter, so has less pumping losses. 7

@RobertoBotticella10 years ago Good morning sir.
i' ve a question please. You said that max power is 220w@700rpm but you use an electrical heating system of 3kw.
so is it correct?

@flatout5815last year Very cool, only thing i was thinking that wasn' t shown here is that these engines would run quietly because no actual combustion is taking place and if they had a quite version of this that could run all the lights in our homes and maybe a fridge or more then with a simple woodstove having a system like this connected to it would mean you could run most electronics in our homes and heat our homes with just firewood.
perhaps i' m dreaming of an impossible system. Gasification might be a better route to run a bigger generator. ...Expand

now get it to spin that alternator (or better) at full speed, charging a battery, with a slight excess of kw/hp. While heating the top with something not electric. Think 90, 238, or 244 times for the answer. Or focused solar thermal collector, or heat reclamation from a

@morritox9 years ago Why not use an axial generator? The alternator is limited by their current regulator, so if the rpm increase over 800 approximately sends less voltage to the coil of the rotor to generate no more than 14 volts.
