I came across it in an article today. A rocket showers (a chimney-like system that heats water by drawing hot air upwards using just a tiny amount of paraffin) and is very economical as it only heats the water being used.
Has any one come across this previously. There are a few mentions of it when you Google "Rocket shower". We may know it under a different name.
