Now that is cool (no pun intended). It suggests multiple additional possibilities as well. If a fireplace or stove was not available, or it would be unwise to create the smoke to use one, a passive radiator system could use this same concept to heat a small room in a house so at least one area was well above the outside air temperature. This could be expanded to a number of potential uses. Thanks for sharing that video Malgus.
