Join Alan Booker for the LIVE Webinar covering, from a scientific basis, how a home heat paradigm inclusive of a Rocket Mass Heater can, indeed, be carbon negative.
More about Alan Booker:
Alan graduated from Auburn University in Electrical Engineering with a focus on computer architecture and neural networks. He currently has over 25 years of experience as a systems engineer and systems architect working in digital telecommunications and large-scale computer systems.
As he gained experience in the industry throughout the 1990’s, Alan began to understand the long-term problems being created by modern design practices. In researching possible solutions, he became interested in Permaculture due to its holistic design approach and track record of creating workable solutions in a wide range of climates and ecosystems around the world.
Alan started studying Permaculture in 2002 and completed his PDC with Geoff Lawton in 2007. After several years of field experience and a variety of advanced training, Alan completed the Permaculture Teacher Training class with Geoff Lawton in 2012 and began to add Permaculture to the classes and workshops he was already teaching on community development, health and nutrition, and nature connection.
From early experiences learning edible and medicinal plants, Alan developed a love of being outdoors and observing natural systems. By his early twenties, he was teaching wilderness skills, survival, and other nature connection skills. Today, Alan uses this background to help students more deeply understand natural ecosystems in order to become better designers.
In addition to teaching the PDC, Alan also provides consulting and workshops on earthworks, soil remediation, composting, forest gardening, holistic management of pastureland, keyline design, aquaculture and aquaponics, off-grid energy systems, and natural building systems.
Alan is the founder and executive director of the Institute of Integrated Regenerative Design, which provides education and research in support of regenerative communities.

Here are our leftover questions. I will ping Alan to come share his thoughts as he is able.
Lori:
Will slides be available after for later perusal?
Jim:
What is the maximum practical storage mass temp?
Jim:
How do the economics work out with dry scrap wood?
Trevor:
Burn bans and mass heaters any issues?
foot slog:
from an earlier topic. What was the website for reforestation of deserts?
I will get with Beau and provide a PDF version of the slides that can be posted just for those who have access to the video. I am still working on parts of the white paper, so I don't want to post publicly yet.
See Ernie and Erica Wisner's book The Rocket Mass Heater Builder's Guide for a detailed discussion of the temperatures of the various layers of the thermal mass. The short form of the answer is that you normally don't want parts of the mass that people might sit on or touch to be much above 100 F. The core of the thermal mass, where the active heat exchange it taking place, will be much hotter, sometimes over 500 F.
Most types of dry scrap wood will burn quite well in a rocket mass heater, so if you have a cheap/free source then the economics would be quite good.
A properly constructed rocket mass heater should be just about the safest option in areas of high fire risk. It is almost impossible to get a spark out the chimney of a RMH, even if it is being operated sub-optimally. The fire is also well-contained inside the burn chamber, making it generally one of the safest options of any wood-burning device.
For reforestation of deserts, see the many resources about Geoff Lawton's Greening the Desert projects in Jordan, and Neil Spackman's Al Baydha project in Saudi Arabia.

For a stand-alone IAQ sensor appropriate for a home, something like the Awair Element works well. It connects to an app on your smartphone so you can see detailed results.
If you are doing large-scale projects such as multi-tenet units or commercial buildings, then multi-sensor systems are required. This would be something more like Awair's Omni or the various options available from Senseware (which just announced that they are rebranding as Attune). The sensors send results back to cloud-based servers, which then provide a portal to view and correlate results. These systems can actually do a lot more than just simple IAQ monitoring since they are designed to handle a variety of building monitoring and automation tasks.
