Well done, clearly the fundamental proportions are OK, but that leak!
Perhaps the time is now right, to slow down a little and spend more time on carefull assembly.

Re: solar air pump?
Hamster I'm getting the impression that buiding a gamma is of more interest than pumping water for your vertical garden? The video link I offered was a poor choice on my part although I'm sure the operator was using a propane torch for convenience. I would recommend reading the article by Dr Colin W...

I would have thought the application you have outline would be best served with a Fluidyne, silent, no moving parts, what more could you ask for?
Having built one many years ago I do remember having to spend some time 'tuning' the pulse pipe but that's just a matter of patience.

500w from NZ
Gentlemen
For those seeking ideas for a SE that does useful work, Peter Lynn's 2500cc beta in a very nice boat.

Re: large lamina flow build
Tom Where as I agree with much of your argument, I do have trouble with the idea of insulating the cylinder. The article I offered from the University of Gent, suggests that there is a performance advantage if the temperature rise during adiabatic compression can be reduced by a Desaxe offset to the...

Re: MYPOWER Stirling Generator !
Very commendable, but you fail to indicate the continuous electrical power output for this CHP, please advise.
It would also be of interest to see a video of this engine running so the low noise levels can be appreciated.

My sentiments exactly, didn't like to say as much for fear of being accused a cycnic, but I think you're spot on, sadly.

Re: Pressuriazation
Jon Like you I believe the double acting gamma offers many advantages and although I have yet to construct such an engine I have spent much time in preparation. I started by measuring the pressure changers on one of my engines using a laptop based osciloscope, then used this information to plot the ...

Re: 1kw engine plans
John Am so pleased to see you are still keen after such disappointment with the V8. I don't know of any plans for a 1Kw engine so you may well have to settle down on the drawing board and design around the facilities you have, which sound adequate for the task. I do believe the double acting gamma o...

Re: Hollow displacer
Chriske This looks like a version of a transferator although most users have the 'hollow pot' facing the other way (open end towards the heater) with the end of the heater formed to fit inside the pot, I fail to see the attraction due to radiant and conductive losses through the displacer. The mass,...
