Jones thanks for the ref to the video. That's a pretty amazing gadget.

One further note, with speculation. High pressure hydrogen is by far the best working fluid for the Stirling engine. Containment of the working fluid during operation of the engine at high temperatures and at high hydrogen gas pressures is essential for the Stirling engine to be an alternative to the internal combustion engine. Most commercial iron alloys are permeable to hydrogen at high temperatures. There are easy solutions to this problem. For instance, many metal oxides are impermeable to protons. However, the interesting thing from the POV of anyone who has studied LENR, or the hydrino, is the possibility of combining an active metal matrix on the "hot side" for hot hydrogen in a Stirling.
I'm not sure but isn't the hydrogen gas *inside* the sterling engine? In other words the hydrogen gives up its heat fast once in a confined cylinder and thus collapses the cylinder. One side of the cylinder is pushed by pressure while the other is pulled by vacuum formation due to cooling.
One problem is having cool air for the cold side. Might be possible to "store cold" in thermal wells at night - at least in the desert.
