CarlAero Stirling Engine running on an ice cube

[ChemicalMikeUK]

does this thing generate any energy or is all of its energy consumed by the moving parts?

You could connect a small generator, but the engine was built for demonstration purposes only.

With regards to this and the hand-heated one: seems both engines generate work by stealing some of the energy flowing as heat from a higher temperature source to a lower temperature sink. The high temperature source in this case is the table, in the other case the hand. The low temperature sink in this case is the ice cube, in the other case the air at ambient temperature. So both are running as efficient heat engines.

Even an ice cube becomes energy. You showed me very very nice truth. Thank you.

Cool!!very sensitive one..who made it?

[MKUltraProject]

ok i thought they where 'heat' engines?

[carlaero]

Well... "heat" is quite relative.. :-)

Yes! It's all relative!
