?? so ... besides making the freight of infinite density so that it's potential energy will be purely gravitational, we probably want to make the atmosphere's potential energy purely _non_-gravitational ... again, to try to get things as simple as possible ... ?? so we're back to a sort of piston, but with the emphasis on there being some sort of "load" on the divider .... ??? and again, idea that ... ??? instead of focusing on "cycle" idea .... ??? keep "delivering loads" until no obvious "waste heat" is left .... ???? ..... ???? .... ?? same temperature and pressure ??? .... ??? ... ?? ...

?? silly idea of mystical "digital" interpretation of sequence of loads of size (?? ...) 2^[-n] .... ??? ....

?? so ... one silly idea that we had was that just mixing samples together might somehow produce macroscopic work, whereas now it seems pretty different ... you have to do something as the mixing occurs .... "impose a load on the divider between them" ... ??? .... ???? .... ???? .....

?? hmmm ... ?? kinetic vs potential approach here (...) ??? ....
