Heat Engines / Another nice novel stirling engine

The power piston is a long way away from the displacer.
Novel cooling chamber.

I made a very similar comment on the video and it was removed.  :-(

Maybe I missed it, but it seems they were very careful not to mention the amount of energy produced over the course of the year.

Heat Engines / Re: Linear solar engine ?

They could have made a prototype in the time it took to make the video. :-)  Looks like a neat idea.

Combining ideas
Just wondering about the thermal delay of the cylinder/gas etc.  It takes a certain amount of time for these materials to heat up vs cool down.  How fast could it run?

There's got to be a word for a material that heats up and cools down very fast, but I can't think of it.
Low specific heat?
A "Black body" may work like that.
