Recent Research on Rocket Mass Heaters (and Bell Design)
There appears to be a huge amount of traffic and discussion through different internet forums about rocket mass heaters and reports from the authors on sales of the book on the subject confirm this incredible surge in interest. I am quite certain that this excitement stems from the tangible possibility that the rocket mass heater concept offers to individuals and families to build their own affordable efficient wood-fired heating system. I thought it would be interesting and useful to offer the following synthesis of recent research I have been directly involved in and links to information . . .
