How would people look at you if you do this in a public place like a restaurant?

i wonder if i can add a crank shaft and a small flywheel will it work?

[djdevil360]

[BaseAurajin]

I like this video. Maybe because I feel very interesting how it can work.

Would you please tell the viewer(s) along with Eng subtles some interpretation but in a casual way. For instance, is there hot or cold water inside the cup? What do you mean by the word 'free'? By the way, could you pardon me for asking such foolish questions (if any)?

[samtibbitts]

there is hot water in the cup. the motor is called a sterling motor and it is a free piston type, as in the part that is moving up and down is free to move as opposed to being attached to a wheel. your questions are not foolish.
