ENJOMOR Hot Air Stirling Engine Generator Model with LED Light and Voltmeter. - Horizontally Opposed Structure Gear Drive.
This model has a cool rhombic drive; most of the reason I picked this one. Takes a little more than 10-15 seconds of heat to get going, but maybe my fuel is not pure enough The voltmeter doesn't seem to work.
Pretty amazing toy for the price.
