rocket mass heater

With it still being winter time, and with many mega-blizzards going on though out the USA, there will always be a need for alternative ways of keeping warm and cooking. Rocket stoves and rocket mass heaters neatly fit the bill here, what is really great about them is they don’t use up loads and loads of wood, in fact you can burn twigs in them quite nicely. Since I first wrote about rocket stoves, there have been many experiments and improvements made by industrious tinkerers, and fortunately for us, these tinkerers also have cameras and are putting up videos of their progress.
