As for perpetual motion, I found this:
Cox Clock- When the weather changes, a barometer drives a mechanism winding the clock. The clock is basically a heat engine.
Atmos clock- basically operates on the same principle.
Not sure if he can be considered a perpetual motion machine. But if true, he certainly exerts more energy than he consumes:
Prahlad Jani, a holy man over 70 years of age, claims to have lived decades without consuming or imbibing food or water. "He spent ten days under
constant observation in Sterling Hospital... During that time, he did not consume anything and 'neither did he pass urine or stool', according to
the hospital's superintendent, Dr Dineshi Desai", according to BBC news.
As for practicality, no, I don't see it being used on a wide scale level. I am all for Helium 3 used as nuclear energy. It will give large
corporations the reason they need to spend money on space industries. I also want to see us mining large asteroids and exhausting those resources;
especially those that are at risk of striking earth. Though that capability is far off and another story altogether.
