[Greenbuilding] Repurposing dried up tube/bore wells for geothermal cooling

[Norbert Senf]

Not familiar with the particular details of that system. However, if there
was a chimney or a tall house was used like a chimney for exhaust, it would
have to be warmer inside the house than outside, in order for the house air
to have any buoyancy.
