why they say a perpetum mobil its imposible what about the drinking bird?

[raaaid]

missleading excess of info to hide this fact:

the eficiency of the dinky bird doesnt matter a dumb since it USES NO FUEL

the ultimate utility of a big eficiency is to get the maximum from the LIMITED fuel

the dipping bird as mr galway pointed works in total dark so its even better than solar panels and obviously much easier to build and they work on fridge fluid like r12

also i would like to know what people think of that ufo on the giant dippy birds video

hey look at what those humans are doing there, will they see it?

a barometer gives hardly any energy but you could build a 100000 m thick barometer that would produce huge energy from atmospheric changes in pressure, the same you could do with the dinky bird, increasing thickness changes nothing but work output
