just 2. then again, you've imagined that:
this is "a revolutionary system,"
the indoor environment is "unhealthy," with "dripping wet ceiling slabs,"
100% rh, actual swimming pools, and mold and mildew,
bathtub experiments say a lot about house cooling,
psych charts and wet bulb temps are needed for understanding,
heat gain by sun on walls matters for understanding,
ashrae's 80 f with w = 0.012 and a cool slab isn't comfortable,
case a) with no fans and b) with fans are the same,
slow ceiling fans use lots of power,
air moving parallel to a cool slab loses no heat,
air can collect moisture without losing heat,
ceiling radiation and convection are linked,
using radiation conductance requires knowing a temp diff,
an 80 vs 78 f mean temp makes a "very significant difference."
heat required to evaporate water doesn't come from a house,
concrete cannot store coolth,
vapor barriers don't keep soil dry,
cool slabs lose lots of heat to dry soil,
they "attract water" up through 800 feet of dry soil,
cooling incoming air is unaccounted for here,
indoor swamp cooling requires "a high airflow,"
outdoor swamp coolers use "only a thousandth" of that, and
300-year-old physics is "unproven fantasy" :-)
