WALLY MENTO'S WHEEL
1976 Popular Science Article posted by Bill Beaty
Minto estimates a slightly larger (40 ft.) wheel with 14 pairs of 1 ft. by 4.5 ft. containers would provide 10,240 ft/lb of work per container as each 269 lb of liquid responds to gravity through a 20 ft level arm. At only one rpm this is 8.69 hp; not spectacular, but low cost and capable of running steadily for generations. The slow rotational speed can be stepped up to whatever is needed, just as with the old-time waterwheels.
What could YOU do with 8.69 HP running 24/7/365 that only requires a little bit of heat to work and nearly no maintenance required?
