Fascinating devices, I've just bought one of these http://www.banggood.com/Low-Temperature-...74187.html,.
The power piston is some form of plastic running in a glass cylinder.
It runs surprisingly well apart from a bit of knocking from the big-ends which are 'C' shaped and just clip over the journals.
The engine is shipped without he flywheel / crankshaft fitted, assembly consists of springing the pointed ends between the supports and clipping on the con-rods.
There's a nice explanation of the principle here... http://www.youtube.com/watch?v=Rd7nLOEsqj8.
(Beware 'Sixty Symbols can be addictive!)
