   I wish that was reversible. it's quite warm here today, and it would be pretty cool to have something that absorbed and consumed/converted heat into something more useful. I understand conversion of most forms of energy to heat can be very efficient, but the opposite... not so much :-/ ABC (*) anyone? :-)

      @lxo In the late 1970s and early 1980s, there were do-it-yourself designs that combined insulated underground tanks solar energy collectors, heat pumps, and water or some other heat dense fluid, with the idea that surplus Summer heat could be collected and stored.
