Geodesic dome shelters are widely known for collecting to much condensation if not vented properly. Rocket Mass Heaters also expell steam. I wonder if we could use this guys take on running copper pipe through the ground in a spiral to collect all of this condensation!
I bet if one would be so inclined to bend some copper pipe inside of a PVC pipe for the downward spiral into the ground that the copper pipe could collect condensation on the inside and outside of the pipe thus making it more efficient. Using a ventilation turbine as previously mentioned in this post could also prove useful for sucking the air through the pipe and ventilating any evaporation from the well in the ground.
I am currently making a geodesic dome out of 1" EMT and do not have funds to test this idea at the moment. I shared the video to keep the cog wheels in our mind turning
Perhaps someone does have the time/funds to test it (or would like to recruit me into there intentional community to test it for them *wink wink*).
