Summary

Paul continues discussing the thing what he wrote “Oil and Water of the Mind” with Samantha, before moving on to his second piece “If you live in an apartment, what good is a Rocket Mass Heater?”.

“[…] I have become obsessed with documenting and sharing bits of information where if half the population did half the things I suggest (without sacrifice) it would solve most of these problems.  The staggering rates of cancer and other ailments, climate change, wars over energy, people having their lives destroyed so somebody can profit....  These thing seem more important than short term loan interest rates, the number of airbnbs vs long term rentals, or the unsightly homes by the river...  And when I try to share, people cannot hear it.  A bit like oil and water.  Over and over and over again...  They are utterly certain that payday loans must be banned...  but learning 60 seconds of rocket mass heater stuff is not possible.  […]”  

In the interest of condensing information to try to bring the time to learn about Rocket Mass Heaters down to under 60 seconds, Paul and Uncle Mudd are in the process of making an infographic comparing the costs of heating a standard Montana home for a year via various different methods.  A full list is in the link below, but some of the standouts are electricity (as a baseline, and all methods are about the same) at $2500, natural gas at $493, Wood stoves at $0 - $1500 depending on how much of the wood you buy in verses collecting yourself (or $0 - $750 for a modern version), and RMHs at $0 - $150 again depending on how much wood you buy in.

Moving on to the second thing he wrote, “If you live in an apartment, what good is a rocket mass heater?” it originated as a question he was asked on the forums, although the full question adds “… going to do if you can’t produce the fuel to run it”.  Samantha’s immediate response was much like Paul’s: you can apply the same argument to any form of heating, although Paul’s approaches it the other way: “What good is a nuclear reactor going to do you if you don't happen to already have uranium in your pockets?”.

Where does the figure for masonary heater wood use come from? I am bot clear on why an rmh, especially a batch box, would be able to extract twice as much heat as a masonary stove. Were these numbers from a side by side test? What style of rmh?

Thanks!

Thank you Samantha! Finally a new interesting podcast to listen. So I can do some hand-sewing, which I can not do while watching an interesting video ...
