It's almost as if Airbus wanted to market a revolutionary hydrogen powered aircraft, just requiring only tanks filled with water and they said:
- A prototype will certainly fly and avoid calculations to be convinced ...
- But before, the only problem is to be able to find cheap water !!!
Not at allbecause it has been working elsewhere for a very long time,
using a well-known basic phenomenon: the diffusion of heat, respecting all known and established physical laws.
There are
almost 2000 years the Romans and others kept ice easily from winter to summer in large underground rooms with very thick walls (meters) which used this property of diffusion of cold (or heat) slowing down as the square root of time for have ice cream in summer, by storing a large volume (10m by cube)!
They didn't need calculations (no computer) but
they knew that the bigger and bigger it is underground the longer it is kept !!
My argument is strictly the same and the calculations seem to me hardly more essential, if the price of an increase in size remains reasonable for a personal achievement.
This works for:

http://www.dlsc.ca
with this very old elementary principle !!
This works in the caves by modifying the variations of external T.
it works very well in houses with thick walls, several meters, like castles (6m) which are never too cold nor too hot. (it is enough to preheat their interior all summer at 25 ° C, 30 ° C with solar thermal collectors, to be warm in winter (walls and roof over 6m thick, because of limestone or granite).
This is verified in bunkers with meters of earth on it, with the heat of summer arriving months late and preserved (phase shift over months):
Christophe had reported a case on econology after visiting such a bunker !!
So nothing revolutionary, nor excess energy, and the only problem is the lack of assimilation and understanding of the diffusion of heat by most people, who then do not believe it.
So, for them, it looks like a conjuring trick, supernatural, yet using only the well known natural physical possibilities !!!
So nothing to do with incredible supernatural energy, at all, but at the limit, an appearance of conjuring trick, very rudimentary, without the slightest manipulation !!.
Drilling has no problem with
www.dlsc.ca
For me, because I don't want to spend more on it than a boiler or a heat pump.
And above all the price of drilling is excessive, while I am sure that their price can be greatly reduced, by reducing their diameter and simple methods.
Anyway some on econology got there for their well for not a round and patience:

with different means to combine, drill tube, karcher, etc.
There are perforators and the most difficult is to find extension rods of small diameter to go deep, because most of the time it is used at low depth in fences or masonry.
