Could you carry a well-shielded container of near-zero K helium (or
whatever) across which the evaporated sweat passes? Would this be
mass-cost-effective compared with carrying water? Is the required thermal
shielding too heavy? Yes, clearly you'd need a powered system at *some*
point to re-freeze the coolant, but maybe this would get you further than a
bag of H2O you have to piss away?
