I really should be more careful. Last night I was hurrying.
The mechanism behind the Minto wheel is nothing like what I described. It's
really an endlessly rotating "dunking bird" with a tube that conveys liquid
to the upper chamber from a lower one on the opposite side. Instead of a
cool head whose vacuum sucks the propellant upward, the Minto wheel
has a hot bottom chamber inside which pressurized vapor pushes the propellant
upward. It's actually a pretty cool idea.
But making one is totally beyond my capability.
