Off-Grid Air Heater using a cast iron dutch oven, a 'camp stove heating over' (the cylinder) and some sand. powered with liquid fuel. looks cool. lots of heat. easy diy. the sand holds (and radiates) the heat for hours. 3 fuels tested. note: the top 'doubles' as a stove burner (boils water in only 3 mins). for indoor or outdoor use.
note: the main part of the video goes to the 5:35 mark. then from 5:35 onward i show the "progression" of the project (including how it all started, and several early models of the unit).
