This is the fundamental issue with this type of engine. If you work on a hot gas cycle, air wins. It starts at a far higher temperature when it is drawn into the cylinder. If you really want to make it hot you would burn it in the cylinder, and then you would have an internal combustion engine...

Ugly is good. My Stirling engine made from scraps of wood, lead sheet and cat food tins was no looker, but was a lot of fun If you think about it, the temperature difference between a flame gulper and a steam gulper are quite large. The steam gulper starts at 100C (steam at atmospheric...

Could we briefly go back to this bit please?: I have given you the benefit of my experience, together with some historical evidence to support my failure. I'm not trying to put you off trying something new, I'm letting you know that you may be in for a disappointing experience Richard

Yes, but... You are specifically making a condensing engine, that where you are starting from. And if you want to make such an engine you need to be aware of what that means i.e. much, much less power And if you want further confirmation, in a rash rush of blood to the head, I set to to make a...

Once upon a time there was an inventor called James Watt. He studied the steam engines of the time and made a major breakthrough - he separated the condenser from the working cylinder. This vastly improved the efficiency of the steam engine by reducing the range of temperatures in the working...

You are right, which is why every car engine in the world is built with piston rings Richard

Have you tried contacting them?: That is a very handsome engine Richard

There was a rhombic drive engine built by someone called Ross in the Model Engineer magazine in the eighties (I think) He was building 'serious' engines with largish power outputs Richard

Hi Tin, that's very nicely put. I like it Richard

How is it that John-Tom is offering these plans for free? Surely they are covered by copyright Richard
