Hello. 5kw for atmospheris kind of too optimistic way. On the other hand - you do need more than 100-150 watt constant power for lights and appliances if hot water/heating is done separately..

For sustained tractors - go for charcoal gasification..

Gamma part - it is gamma with very thick displacer rod. Kind of ringbom engine with displacer made so thick, to produce most of power. In long description (i think i will make a video on it) We have one expansion space. And two compression. One is at 90 degree, other is on 180 degree. In sum - its g...

Pre assembly of heater / cooler / regenerator

Did run more simulations, to find a configuration with same bore x stroke and cooler length. slotted heater and cooler 6x1 slots for cooler x 100 , 5.5 id tube with 3.5 internal tube for heater x 37, both 51 mm length https://i.imgur.com/BPFSPhD.png result: https://i.imgur.com/vGrQsJo.png Drilled co...

Give me you email, will send some exerts from book. It will be better to run pressurized, due to lower total friction loss -ie 1 bar at 1000 rpm is close to 2 bar at 500 rpm, but latest one have twice lower piston ring friction + aerodynamic losses too.. I did it ran with your current geometry - its...

You welcome. Do you have Senft book on mechanical efficiency of stirling engine ? Changing angle from 90 to 120 or 125 degree is not as hard. For our baby power level - aluminum crankshaft is totally ok. I was able to make new one for my first attempt in one evening turning session. Do you have bear...

Btw - my project was also born from similar china twin 65mm bore air compressor..

This is for 125 angle between expansion and cooling: https://i.imgur.com/qQQUiSW.png Red is force work area then buffer pressure is half mean cycle pre...

And regenerator od id

Working fluid pressurization ? Piston rings one way ?

Turned in lathe to give final touch.

~480 cm2 of area.

Heater cooler tube length, diameter internal and numbers. Regenerator size and fill..

Please provide you geometry data - will make some simulation run for you.

Btw thsi guy was able to make it. https://m.youtube.com/channel/UCe3fCFq8H2cVzbVA-_lzO6Q

Tomorrow happens:

Internal alternator taken from china 250w / 36 volts ebike motor. Plus some space left for extra flywheel.
