cooling a house with a rocket mass heater

Awesome Paul! I am looking forward to building a rocket mass heater on my next place. I had no idea until now you can also use it to cool the house. Today it will be around 115 here in Oregon and I sure could be using this. Thank you Paul!

Part of me wants to supercharge the process with a DC fan, but that adds complexity.

Any concerns with the condensation that will form on the RMH internals? Corrosion to metals or impacts on the cob mass?

I really wish that would work for summers here.  The night time temp doesn't always get much below 90 and the humidity is close to the same.  I hope that one day I can have this type of experimentation on my farm to figure out what works for cooling and a gajillion other things.  Paul, you inspire me.  Please keep on doing what you do!

I imagine that this could be improved in few ways...

1)   Paint the chimney black on the roof so you would get a solar chimney effect.


2)   Use of earth tubes to feed the rocket stove so cool air would be pulled thru the thermal mass.


3)   Use of a solar fan in the chimney via a venturi to help speed up the process for the summer months via a thermastat.

Heat by putting a metal rain collecting/heat collecting roof over the south berm.  Pipes circulating through the berm would have valves so that heated air could enter the top of the loops and exit the bottom but not reverse when the roof cools.  Of course you could reverse that if the climate or a storage space required cooling .  A challenge project for the appropriate technology jamboree; make a root cellar with a night radiating cooling roof on the north side.
