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!
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!
