Hello in our small forum. On st05g stirling engine piston rings are made from iglidur with slice - just as an ordinary piston rings + plus have some spring to energise them. Their bore is 75mm as far as i remember. But they are kind of precious one. Same are used in whispergen, but made from graphit...

Big like from me for this document.

I think there are a number of companies marketing mostly large scale cogeneration systems, taking out old diesel generators and replacing them for large institutions, like hospitals, military bases, etc. so they are marketing where there is the most money. The residential market is much less lucrat...

Then do you need it ? You want to design it and build or just buy ?

Its all depend on targed "market" non concentrated solar stirling is just to big to ship.

But - 90 degree in alpha stirling is not equal to 90 in gamma :)

For ross yoke you got 90 phase angle.

Gamma works with less efficent drive system. Alpha have to be built using ross yoke or be twin action - 4 cylinder to be efficient.

I think a good small portable multi-fuel Stirling generator is something many people are looking for and would buy, if it were available. I know it is something I would love to have to take along on camping trips or living off the grid. Videos from link in opening post: https://youtu.be/T8OY43o1tL8...

Hello. I think only v160 or its current clone was mas produced. And it is in your power range.

The correct fixture to make it 90 degree V twin (milling angle + cylindrical square)



Hot piston / displacer assembly

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...
