I like simple solutions ....

Others were not shy to apply them ... right down to the core!

Okay. But without capitalism, which you condemned above, who will pay workers and materials? Can we start a project the size of a thorium power plant without capital?

In capitalism, nothing can be done without capital.
it's the Palice that says it : Lol:
This is the unsustainable world in which we live.

In the durable version:
The resources are not limiting for building such plants, compared to the resources necessary to use the low-concentrated energy from renewable energies.
In a sustainable world, one can consider other motivations than wages.
(the ticket or the schlague work very well : Mrgreen:)
More seriously I don't have an assured answer, just intuitions, I'm looking for ...
Since the world is sustainable, the basic needs are met (yes, yes, by the work of real people, or even AI robotization in part, itself sustainable.)
A world with assured material comfort, is a world with a generalized climate of confidence (in contrast to the generalized insecurity with capitalism), one can imagine the advent of an individual desire for meaning, a desire to serve: service, to others therefore to oneself, since it would be a shared value and it is gratifying to render service.
Admittedly, this implies going beyond a psychological course ... : roll:
This desire to render service could be the motivation of those who work in the construction of these power stations, of others working in the food etc ... each one according to its aspirations and capacities.

A bit like the cathedral builders in their time.
To my knowledge, they perceived enough to live on but did not make a fortune. They were essentially satisfied with their work.

We are going to ask the Vatican to sponsor us.

In short: I would simply say for the interesting initial subject.

And I'm not talking about aquaponics : Mrgreen:
It will turn off topic

1/2 greenhouse covered with PV
Above-ground cultivation
aquaponics
Solar drip that works with cow dung or sea water (we recover after dry matter or salt)

It is neither for nor against global warming.
It's just a matter of common sense

It is not because I promote an abundant and concentrated energy source (gen 4) that I am against solar or wind, where it is relevant.
Although I am nuclearized at home, I use (intend to use) PV in the garden: no cable to draw and resilience on these uses, in case Mr. Globalization bug. : Wink:

The only criticism I would make of vegetables from aquaponics is the nonexistent taste.
We can also use herbivorous fish, fed with duckweed, itself fed with chicken droppings.
In short, recreate a mini planet Earth. : Lol:

you need more than a micro generator of liquid nitrogen to spend the winter and refuel your car with liquid nitrogen. : Lol:

With a 10 kW you can sell liquid nitrogen to your neighbor or exchange for potatoes.

Personally I prefer an electric compressor and hydrogen bottles at 300 bars / 4500Psi in carbon. Compressor + 1 bottle = 500 € minimum. I'm not sure how to get H2 from H2O. There are several methods, it seems.
But it's a matter of perspective and cost

I think that it is hydrogen or liquid nitrogen there is interest to be put in several to have a better output for a lower cost compared to the kw. Create a mini-network between neighbors in a way. While one produces energy the other consumes, it reduces storage needs
