!!!!!!!!!! solving the biggest carbon problem in a cold climate - webinar with Alan Booker

Happy 2026 permies community!
To celebrate a new year we are sharing with you Alan Bookers recorded webinar on
Carbon Negative Mass Heaters for free!

Alan Booker covers, from a scientific basis, how a home heat paradigm inclusive of a Rocket Mass Heater can be carbon negative.  
Includes a full 133 minutes of presentation, along with a 49 page .pdf file of Alan's slides and data.

Very useful and compelling presentation on ECOEI ie source  based energy cost comparison with RMH.
Some questions that resulted for me...
1. what was the climate zone and  therefore heating degree days of  the test site in case study? (that yielded 3KBTU/yr energy demand for heating.)
2. What costs were included in the poplar coppice wood fuel source? labour to cut/harvest/stack?
3. how could the super hot fuel gas be used to heat hot water or  drive a small steam generator? Is that really good idea for generating electricity off grid?  Hot water could be piped to radiators in a house with rooms divided by walls and doors, even on different floors.

Very interesting, thank you!
If I understand that carbon negative argument correctly, it is that coppiced trees sequester enough carbon in their root systems that even harvesting a certain percentage of the biomass leaves you with net negative carbon emissions. If that is correct, would any clean burning wood heater be carbon negative? Even if it takes more wood, that just means more coppiced land =more sequestered carbon, yes?

I am in the end process of planning my kitchen rebuild and thought I would incorporate either a rocket mass heater or just a masonry wood stove.  This was great information at the right time.

It's about 24 by 28 ft and will be as air tight of a shell as I can make it.  If I'd like to heat it quickly on a winter day and have it radiate heat for 24 hours, how much mass do I need to heat with a single burn?

I plan on incorporating thermal mass in the main room itself and additional passive solar and soil thermal battery on the south side for the shoulder months.  So I'll need about 3 months in deep winter for the RMH assistance.

The main heating area will be about 28 by 14 ft, 8 to 9 ft high.  How do you adjust the quick heating portion of the bell to the long heating mass of the rocket stove?

We do get down to -20's F on some nights.  While the USDA says we're zone 5 now I can't count on more than 4 in my particular location.

Any help with those 2 questions would be helpful.
