Rocket stoves burn very hot, are energy efficient using little biomass and are almost smokeless – significant advantages for conserving wood, cooking efficiently and preventing respiratory diseases, a major problem in the two thirds world. Dr. Larry Winiarski shows you makes a clean burning rocket stove using just 16 adobe bricks. Adobe bricks are lighter as they contain organic matter (chopped straw, rice hulls) and provide much better insulation than regular bricks. With better insulation you'll get a hotter chamber, a cleaner burn and less (or no) smoke. You can make your own or alternatively use conventional fired bricks and coat them in a clay plaster for even more insulation*. You can build this outdoor cooking stove totally for free.
