Idea's from Dan Condon

Here are the idea's Dan sent to my email.

"Comments on research project

1. You may wish to try different materials for the pipe. Since this
is where the heat transfer takes place and will also be where
condensation or moisture absorption takes place the material and
thickness of the pipe will have a noted affect on the efficiency of the
system. For example if you use plastic pipe it will likely not transfer
heat that well and will not absorb heat that well compared to metal or
clay or wood pipe.

2. The best way to remove heat from air is through evaporative
cooling - by passing dry air over or through water, evaporation will
draw a large amount of heat from the air - in our climate for cooling,
the addition of water to the air would be a plus.

3. Pipes that pass through water will transfer heat better than a
pipe in contact with dry ground. Alternatively a car radiator that the
air passes through could work well.

4. The insulation under the building probably is not necessary as
that area will not reach the higher outside temperatures.

5. An alternative to laying serpentine tubing would be to install
fins on the inside of the tube to create turbulence.

6. An alternative to bringing the cool air into the bottom of the
cabin is to have it come in at the very top of the cabin where it will
mix with the air as it seeks out the lower level. When bringing cool
air in the bottom the bottom floor will be always cool and the top floor
will be always hot (like a conventional basement and upper floor of a
house). Or try both to see which works better.
