Free air conditioning and heat


This is a very simplistic air conditioning/heat/fresh air system found everywhere on the internet. I found a patient date as early as 1903 on one version. The funny thing is it works as well today as it did then. This is the type of system that we will use in our underground housing project. If you can imagine, 63 degree temps coming from a simple pipe on a 95 degree day. Add to that >55 degrees coming from it on a otherwise freezing day in the winter. It wouldn't take no more than a wood stove or alternate heat source to make it very comfortable. In our underground house design it would take far less to make it a very comfortable 68 to 72 degrees, but who doesn't love a fire.
