These are not perpetual motion machines, they are heat engines!

[jazepsjazeps]

super!!!! how much power they can generate?

[jazepsjazeps]

super!!!!

[josephdupont]

why not make energy from these???

[518schenectady]

so u can make that thing go forever with a little water why not put a little magnet and copper on it and see how much electricity u can get out of those big ones. probably enough electricity to charge a cell phone or run some led lights 24/7. with a few rooms full of them or an attic or basement maybe u can power the whole house. let us know if u do

[oomblikkies]

Would it be possible to generate electricity with this?

[thepianoaddict]

yea it is possible

[chobot00]

drinking birds arent powered perpetual motion, they use heat to move.

[phtmexplo]

+ water evaporating

[intbn]

what fuel from the enviornment does it use fakui? heat?

[knuckles575]

Yes heat, It is a heat transfer engine.

[Jimraynor45]

isnt this suppose be like impossible?

[lemuelbecc]

Cool. Seeing it oversized makes the principle more understandable.

[Psychild88]

haha i drinking birds they are sooo cool! =D

[rossjamesparker]

Free power baby.

[phtmexplo]

nope, same power as anything else that uses power.
