Efficient, Clean Wood heat

Rocket Mass Heaters have a lot of advantages over a conventional wood stove. They:

• Let off heat gradually over the day, so you don't need to keep tending a fre
• They burn up the smoke, using that energy for heat, and not releasing nearly as many CO2 emmissions into the air. The exaust is nearly pure steam.
• They burn up the creasote, making the burn not only safter, but also more efficient.
• They generally require about 1/10 of the wood to heat your home.
• You can build a rocket mass heater at home, in a day or two.
• It releases less CO2 than natural gas or electric heat
• Even if you purchase the firewood, it still costs less to operate than natural gas

Here's a nice diagram of the inside of a rocket mass heater (from Paul Wheaton's article on Rocket Mass Heaters):

And here's the windflow in action, and a completed rocket mass heater (also from Paul Wheaton's article on Rocket Mass Heaters, which happens to be a wealth of rocket mass heater knoweldge):

DVDs:

Paul Wheaotn has now made 8 DVDs on the subject of efficient wood heat through the power of Rocket Mass Heaters. 

Here's a quick summary of what is on each of the DVDs (see this article on wood heat to find out more):

• DVD 1: Fire Science (learn how Rocket Mass Heaters work)
• DVD 2: Sneaky Heat (building an even more efficient Rocket Mass Heater)
• DVD 3: Boom Squish (the dangers of heating water in a pressurized system)
• DVD 4: Hot Rocket (making a rocket stove that cooks quickly and effieicently)
• DVD 5: Cob Style (building a cob-style rocket mass heater)
• DVD 6: Pebble Style (building a pebble style rocket mass heater that uses pebbles, instead of cob or masonry for it's mass)
• DVD 7: Shippable Core (how to make a ligher-wieght core of a rocket mass heater.)
• DVD 8: Innovators Event (rocket oven, rocket, an outdoor rocket mass heater/cooker/smoker; A "batch box style" rocket mass heater with measured output cleaner than anything we have ever encountered)
