As an example of waste air conditioning
we looked at the cost and decided no installing instead an idea I

Pumping air through buried pipes results in very cool air for the

It did involve some trenching and finding some plastic pipe being
still cheaper than just the install labour cost of one split a/c
over all an immensly satisfing outcome at least 4 times a year


Great idea!


( 2 metres down the earth never gets above 5 Deg C) in Brisbane

I find that impossible to believe as the air temperature would hardly
ever or never get below that.
the physics is easy
] now go try it


I take you are saying this is not a mistake. So please explain the physics.
How can the subsoil be maintained well below the average annual temperature?
