one more thing i would like to know is "what metal should i use to make the top plate to catch the heat" should it be aluminium copper or steel. Or steel above the aluminium to lose less heat from above into environment. copper would be costly i guess.

thanks for ur reply and advice. I saw a multicylinder engine in which all pistons in same phase and all displacers in same but 90 degrees out of phase to pistons. But i may take your advice to work on this kinda configuration. Manual start is what I believe right now but may be I can use the same mo...

well i found the pics and posted I need help regarding the power it can generate. The size of displacer cylinder will be around 10 inches dia, 14 inches height, . I want to run a dc motor of car blower to charge the battery or may be the car alternator. There is no problem of sunlight in my place it...

I made a small ltd gamma stirling engine that runs with solar heat provided its lower plate is cooled with cold water or ice. You can see the video http://www.youtube.com/watch?v=rVA11giUIpk. Now i have plans to build a larger engine that yield useful energy to charge a battery atleast of 12v. This ...

I am working on ringbom with two diaphragms. One as piston other attached to displacer. Has any one else tried that. I guess it will give me an absolutely tight air seal where i could pump some air with valve. I would like to get any advice or comments. Hope to post the video when it gets ready or o...

well all my tries to make paper and plastic piston and cylinder to work failed as high resistance did not allow the engine to run though it moves a bit

Sorry

Please check the video here i accidentally deleted the previous video and uploaded a better one

I want to know whether any one had tried making ltd versions of beta and alpha engines using diaphragm. I would appreciate the help in this regard.

my first attempt is not very bad but i am planning to change the materials from paper to aluminium foil and glass tube

you are right about the materials but hard to get for me so trying somethig simple the feather weight of these might help

i have made an engine with diaphragm that ran. And felt why i failed with metal piston as it was heavy and the power this generates is low . I plan to make a light piston. I will get a cylinder plastic syringe and use a paper to make the piston. I will use a 1 cm wide paper strip to make a roll that...

you are right i did observe water vapour condensing in the plastic tube near the join with glass tube i will try some other liquid. What can be done to increase the power of this engine one is temp what other factors?

I made a water piston lamina flow in glass test tube and that works but its working is not reproducible all the time . Some times it works easily and some time it doesn't. I have sealed the thing pretty well and heating near the generator. Attached a plastic tube containing water to the glass tube. ...

Great to tell you that with the help of this forum and few others on the net I got the engine running finally. I enjoyed its first flight, and every bit of it. You can see that here http://www.youtube.com/watch?v=_PejtxgESLU
