How about a video?
Made from various junk. The displacer is floral arrangement foam, and the displacer chamber is a coleman lantern globe. The bearings are from dead hard drives. The flywheel is a masonry blade for a circular saw. The hot/cold end plates are pieces of one of those rapid thawing boards (just aluminum).
Thanks. Nice piece of work.
