Re: Dual stirling generators electrically heated
From a heat source with Sterling engines recovery is at most 35% - Very good efficiency compared to other motors.
What you are saying is fine, but all that heat is wasted - check out the other threads in this forum and you will understand.
Maybe some one from this forum can answer better than me.

Re: Dual stirling generators electrically heated
Impressive Engines - I am not sure of the electrical robust radiator running both engines to produce 20kW. It would mean you are getting more energy out than what is going in. If you accomplish this you will go into the history books. Give it a go and I wish you the best - There will be a lot of sur...

Re: Dual stirling generators electrically heated
Hi Melvin
Not sure what you want to do will work. If both engines are the same size and one is a heater for both, you will be trying to do the "Holy Grail", that is a perpetual motion machine. Physics show this cannot be done if you want the same power output to boyh.

Re: the volume ratio between displacer cylinder and power cylinder
Hello OscarmikeIan
Ian is correct with the ratios 1.5:1 for Stirling Engines. It is the optimal ratio that has been tested for a very long time.
When using LTD Engines then this will be different.
You cannot have a larger piston capacity that the displacer as the engine will not work at all

Looks very interesting. I would think this would be good for LTD engines if the product is lightweight.

Re: Propane burner design
Hi Ian - In the winter time you could possibly wrap a few coils of tubing around the hot end to make the cold frozen gas into a liquid for full firing.

Hi Thanh
Oh! What a nice engine mate. I like the work you did on the fuel tank and the gearing for the generator.
Well done, I love it

Re: What fastener to use on Hot Cylinder?
I would use high temp silicon (red). It comes in a handy tube and you can purchase from any bearing, engineering or even Bunnings stores.
Glass does not transmit heat readily so the adhesive will wok here quite well.

Good info Alfista. They were sure were heavy when they only used cast iron.

Re: Heavy or lightweight displaser for more horsepower?
Hi Wellington
A displacer that is extra light weight is very beneficial. Make it light as possible yet sturdy and do not use aluminium as the displacer as in high heat they will melt or distort badly. Ian can show you some photos of what can happen using alloy as a displacer.

Re: Stirling powered toy car
HI Ian
I have tried to get 3 and 4mm in heat fused plastic belting (polyurethane I think) but with no luck in Australia.
Do you happen to know where it can be purchased, even on Ebay it is hard to find and expensive.
Maybe others are having trouble trying to find the stuff.

I also have used rubber bands to drive my water pumps on my hot air engines. I have recently found some soft rubber that is used for sealing drums etc. Comes in 4mm up to 12mm. You glue it with super glues and it doesn't let go even when going around 20mm diameter pulleys under load. Better than usi...
