Building a Cob Style Rocket Mass Heater - three copies of one DVD

UPDATE!  CLEARANCE!  Three DVD copies of the same thing will be sent.  So you might give them to people over the holidays or something.




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.

This DVD is available here as a standalone. We tried to make it dual purpose, something that could fit within the new 4-DVD set, and something that could also fit for people that want just one video.
