Response to LDT Stirling and a heat pump
<r>Using a heat pump to increase the efficiency of the Stirling engine would decrease the total efficiency of the system. It would be like running your air conditioning in your car for a radiator system...it just doesn't work, you'd just be running your engine harder than using a radiator. 2nd law o...

Response to Neat way to make a piston
<t>Works like a charm. I just sprayed some cooking oil in the cylinder, put the mixed JB weld in and, voila, a nicely made piston. I just sanded the sides lightly and it is a nice close clearance fit but still slides easily. I'm sure using brass and aluminum or graphite is lower friction, but for th...

NASA Link
Here's an interesting link from NASA with the Stirling engines that
were developed for deep space applications.

In case anyone is interested.

Response to Stirling Engine powered Flashlight
<t>I have to say that I disagree about them being a dismal prospect. I recently watched a video on youtube from a french website where a man built a LTD using a diaphram piston that was running off of the temperature difference from the evaporation of water, and it had a small alternator he made tha...

Neat way to make a piston
<t>Now, I tried this once but I didn't do it correctly, but apparently it<br/> works. One way to make a tight fitting piston in a cylinder is to get<br/> some JB weld, mix it up, take the cylinder that you are going to use<br/> for the power piston, put a light coat of oil on in the inside of it<br/...

Response to Engine speed(rpm),volume ratio & pressure ratio.
<t>There are WAY too many design factors to easily answer your question. I would recommend finding the following books at your engineering library, I read these last year while in college and they helped me understand engines and all the factors that go into designing them much better. The first is ...
