I believe that those in power do not want a decentralized and practically autonomous system once manufactured.
more consuming nothing in perpetuity and therefore also without any taxes that come in, unless taxing the sun on roofs like swimming pools !!!
On the other hand in the Canadian documents I see nothing concerning the costs.
Do you have any info on that?
By searching well on Canadian research publications on the internet, one has to find, but I haven't spent enough time there.
Otherwise, I know on the internet that Canadians have given research grants on renewables which dlsc.ca benefited in part from Drake Landing Solar community, but I have no precise information on the price.
It does not have to be huge, given the simple technology, 30m2 solar collectors, basic drilling on 96m per pavilion (a shallow well), in comparison with nuclear power which benefits from all the enormous military research they almost completely bleed, that civil nuclear never paid !!!
In my opinion, we can greatly reduce the price, simpler sensors and very low price, with a larger surface area in summer (see the rudimentary forhorse test without glass 200l of water at 56 ° C:

)
and simplistic small diameter boreholes used by geosec or uretek:
This company has a good part of the solution to drill inexpensive small diameter (2cm) in foundations with significant depth and waterproof on its videos:

as well as others in this niche that pierce as cheaply as possible before deeply injecting a very expensive expansive resin per m3:

So in my opinion, we can greatly reduce the price to be at the level of a heating installation with usual boiler,
that she will no longer consume anything in perpetuity, and the current price has no valid meaning, as for the very first realization of a new concept.
So that we deign to consider it in France, we will need a Fukushima-Tcherno in France, with evacuation of an entire region for centuries, and with a catastrophic rise in seas from 2 to 4m per century (rate of 13000 years) engulfing all the coasts.
