He's claiming over unity for the GAP motor. However, my question is how much of its own energy is used to keep itself running. If he's got only enough extra to run a single lightbulb, it will have to be upscaled quite a bit, adding to the production cost quite a bit. And that is if he's correct abou...

Thank you, Ian. The dead space is the air in the center of the pipe, the air not touching the inner walls of the pipe? Is that why I see people putting steel wool inside the chamber, trying to get more surface area for heating? Would the steel wool work inside that pipe/radiator in the rocket stove ...

Hello, everyone. Looks like a nice place you all have here. Looking forward to going through the posts and learning about these motors. I've been looking at these motors for a while, now. My interest is in alternative energy. Stirling motors may fit well with that. Specifically, solar concentrators ...

The first is a question. I've seen that most Stirling engines out there use a fairly small chamber, which is heated to drive the piston with expanding hot air. Why not add a long, thin pipe to the cylinder and heat that, instead. For instance, a thin pipe could be bent back and forth to fit inside a...
