Tom,

- yes, it is quite a nice, readable piece of work with some nice photos. Also, there is a useful table showing how the LTD that she worked on varies in rpm as a function of temperature difference.

Turns out my "new style" LTD regenerator is not so new after all.

I just came across this video from 8 years ago, showing the assembly of a 3D printed Ringbom type LTD with essentially the same type of stationary regenerator on the sides, surrounding the displacer rather than being incorporated into the displacer itself.

That this is also a Beta type free-piston LTD Ringbom is also interesting.

There is a 3D print file for the above LTD Ringbom free-piston engine on Thingiverse
