This was the first 4-DVD set created by Paul Wheaton and his merry band of rocket mass heater innovators. It is a great introduction and shares lots of good information about fire in general, and what can be done with rocket mass heaters.
DVD 1: fire science
This is where Ernie and Erica set stuff on fire in all sorts of wacky ways. This is the foundation for understanding how rocket stoves and rocket mass heaters work the way they do.
DVD 2: sneaky heat
The wood burning stove built in this DVD is the result of a collection of experiments that led to a rocket mass heater an order of magnitude better than any previous rocket mass heater. For the first time ever we have a shippable core.
DVD 3: boom squish
Named after a series of podcasts where we discuss the dangers and strategies of alternative hot water. Caleb Larson and Ernie work together to talk about how to do this right. Caleb is a professional alternative hot water installer and is very familiar with the explosive properties of steam, flash point and vapor lock.
DVD 4: hot rocket
We set out to prove that a few twigs can outperform a huge propane turkey cooker. Mission accomplished. This is with a J-tube style rocket stoves. Other rocket stoves feature an L-tube style the requires constant manual feeding. The J-tube style is self feeding. This DVD will also have information on some tiny home made cookstoves, and several different pocket rocket designs.
If a person was going to get just one DVD, this would be the one. A cob style rocket mass heater is "the old reliable". We have two projects to demonstrate this technique - one in a log home and one in a tipi. We put one in a tipi as part of an experiment to test how warm a person can be with a rocket mass heater and zero insulation. We interview the couple that stayed in the tipi for the first winter, with a strong focus on how comfortable they were when it was 26 degrees below zero.
We will show the construction of three pebble style rocket mass heaters. The difference with these is that the mass is usually a wood bench filled with pebbles and rocks. A different aesthetic. These designs are (relative to cob style) easy to move and modify. They also tend to be lighter, thus, better for installing in places that have a wood floor.
DVD 3: Shippable Core
The kickstarter from two years ago showed an early prototype. We were certain that by the time the video came out, people could buy a shippable core and plug it in. In the time that has passed, that didn't happen. We ended up releasing a variety of information on how to make your own - and now, in this video, we supply the "how to" video for a variety of techniques.
DVD 4: Innovators Event
Last fall we put on an event where Ernie and Erica invited several rocket mass heater innovators that they thought were the best in the world. Each innovator was provided with the materials to create whatever they wanted. The results were: "the ring of fire" - a rocket mass heater shaped in a circle with glass to show the burn; an outdoor rocket mass heater/cooker/smoker; A "batch box style" rocket mass heater with measured output cleaner than anything we have ever encountered; An indoor rocket stove, griddle and water heater.
