i like the 53 f phase change material. for evaporative cooling in humid
climates, we might have another desiccant layer to absorb water vapor,
eg a licl pad above a moist pad in a shiny hard hat.
other "non-compressive cooling" options might include cold tubs, exterior
window shading, fans, moving to maine, less clothing, a higher surface to
volume ratio, a bean bag chair or belt or collar filled with water or copper
bbs, one of those car seat covers with stainless steel vs wooden beads, knee-
high synthetic "cool sox" (tm) automatically dampened from a water bottle
on the waist, camel-kool (tm), a thin water-filled back pack worn under
a shirt with no insulation between you and the water, attached to a small
damp radiator built into a pith helmet with a battery/photovoltaic fan, and
head sink (tm), a close-fitting metalized heat sink hat with lots of longish
punk pointy heat pipe fins.
