Paulownia might be superior to balsa for displacer construction. Balsa weighs about 10 lbs per cubic foot, paulownia about 18 per cubic foot (oak about 40, for comparison). However, the shear strength of paulownia 5,740 psi, more than twice balsa, 2,800. A 3/16 cut of paulownia gives the same streng...

Perhaps you are referring to the prototype of the Stirling Technologies engine? 5hp engine it hopes to put into mass production. http://cdn3.wn.com/vp/i/2f/2d63ae191678b7.jpg I am still too early in the reading/learning process to be talking design, but I am playing with displacer ideas: At the bott...

Thank you, Mr. Larsen for helping to put displacer shape, size and stroke into perspective. I have enjoyed visiting your website often and learned from it before joining here. A pleasure to meet you. It is you and other miniature builders who have preserved and refined the Stirling concept thru the ...

Ah, thank you. Importance noted. That prompts a theoretical (and I have observed in my reading how well versed you are in the formulas): Should we be concerned about extracting too much heat on the cooling side, reducing the overall temp too much and reducing output? I doubt we could be that efficie...

A pleasure to meet you, Ian SC. I have enjoyed reading and already absorded quite a bit from other contributions you have made to the forum. I especially enjoyed the machinist dislogues you had with a couple other forum members attempting to Stirling a heavy V airpump. Admired the ingenuity... clean...

Hello. I am a newbie and this is my first post. Mechanically inclined all my life but not mathematical enough for engineering calculations. I hope my ignorance and ability to misunderstand do not prove frustrating to those kind enough to prove answers and suggestions. Question 1: Understanding that ...
