if you isolate an
area of the planet .......
you will have all the radiation coming from the
nuclear power station earth
up to you ..... with out the dissipation from the
maybe cold day ..... in
your moderate climate ......
if you measure the temperature of the ground on a
hot day in your
moderate climate >
you will ... depending on the evaporation rate of
the water in this >
and the vegetation cover over it > be finding the
ground a lot cooler > as the air !
you can use these phenomena to have a
permanent air ventilation
50 ° f air ..... summer or winter ...... in your
with out the high power
consumption of a
regular .... air
or heating up all the way from winter temperatures !
so .... you can build a set up like this ..... above !
with a small
with capacitive down regulated
power supply eg
even will turn
the meter without
any thing else !
if you want to improve on this .......
then you take
the air in a
....... well and a copper pipe
up to 4' below ground water > because of the
now .... most ground water supplies .... vary in their
level .... so > this be low will adjust to this >
and .... to improve the effectiveness > we can add a geo
pre heater > be vor going into the well itself ....
if your ground water level is
30' or more .....
you can fashion this setup above >
where as the heat exchanger is burried in the damp sand >
transfering the energy from the ground water to the air for
ventilating your building !
if you are needing water as well >
you can add this at the same time or seperately ....
you will need a provision > to prime the pump > before
taking up operation !
