Stirling Beta Engine - Low Temperature Version

And the "low temperature" feature should be underlined twice, because chinese designer used thermoplastic (it's NOT glass) for the transparent cylinder in the base. So it's really not very wise to place this device close to any other heat source than warm liquid, because this cylinder will quickly melt and will not seal the piston chamber anymore. :-(

Fortunately, I managed to repair mine (using two jam jars, with hot water inside, hot air gun) so the melted part is not visible anymore and the engine is functional again...
