True Left

"So I'd like your advice on the entire community and how to build it,"

First you should formally write a budgeted proposal, which you can post a link to when it is ready. How much do you estimate the initial costs to be, and how much money do you estimate being able to raise (how?) towards these costs? How many people will initially populate your community, and what resources will be consumed per person per unit time? What are the qualifications for becoming a member? And so on. The more detail you can provide, the easier it will me for me to tell you if/where your plans may be deviating from our ideology, which you can then revise.

"Self Sufficient, Technocratic"

I find this extremely unlikely, considering that even entire present-day countries are rarely independently functional at a modern level of technology. The more complex the machine, the larger the network of global interdependence required to build or repair it. Take solar panels, for example. If your community is to be able to manufacture its own solar panels, it needs to be able to manufacture its own crystalline silicon FFS:

amorphous silicon is grown using traditional techniques such as plasma-enhanced chemical vapor deposition (PECVD). The crystallization methods diverge during post-deposition processing.

In aluminum-induced crystallization, a thin layer of aluminum (50 nm or less) is deposited by physical vapor deposition onto the surface of the amorphous silicon. This stack of material is then annealed at a relatively low temperature between 140 °C and 200 °C in a vacuum. The aluminum that diffuses into the amorphous silicon is believed to weaken the hydrogen bonds present, allowing crystal nucleation and growth.[53] Experiments have shown that polycrystalline silicon with grains on the order of 0.2 – 0.3 μm can be produced at temperatures as low as 150 °C. The volume fraction of the film that is crystallized is dependent on the length of the annealing process.[53]

Aluminum-induced crystallization produces polycrystalline silicon with suitable crystallographic and electronic properties that make it a candidate for producing polycrystalline thin films for photovoltaics.[53] AIC can be used to generate crystalline silicon nanowires and other nano-scale structures.

Another method of achieving the same result is the use of a laser to heat the silicon locally without heating the underlying substrate beyond some upper temperature limit. An excimer laser or, alternatively, green lasers such as a frequency-doubled Nd:YAG laser is used to heat the amorphous silicon, supplying energy necessary to nucleate grain growth. The laser fluence must be carefully controlled in order to induce crystallization without causing widespread melting. Crystallization of the film occurs as a very small portion of the silicon film is melted and allowed to cool. Ideally, the laser should melt the silicon film through its entire thickness, but not damage the substrate. Toward this end, a layer of silicon dioxide is sometimes added to act as a thermal barrier.[54] This allows the use of substrates that cannot be exposed to the high temperatures of standard annealing, polymers for instance. Polymer-backed solar cells are of interest for seamlessly integrated power production schemes that involve placing photovoltaics on everyday surfaces.

A third method for crystallizing amorphous silicon is the use of thermal plasma jet. This strategy is an attempt to alleviate some of the problems associated with laser processing – namely the small region of crystallization and the high cost of the process on a production scale. The plasma torch is a simple piece of equipment that is used to thermally anneal the amorphous silicon. Compared to the laser method, this technique is simpler and more cost effective.[55]

Plasma torch annealing is attractive because the process parameters and equipment dimension can be changed easily to yield varying levels of performance. A high level of crystallization (~90%) can be obtained with this method. Disadvantages include difficulty achieving uniformity in the crystallization of the film. While this method is applied frequently to silicon on a glass substrate, processing temperatures may be too high for polymers.

So your community would also need to be able to manufacture at least one of the following: a) aluminium; b) lasers; c) plasma jets. And each of these in turn requires other stuff in order to manufacture, which your community would also need to be able to manufacture. Do you see how crazy it becomes?

The whole point of promoting the value of self-sufficiency is to encourage people to be willing to give up complex machines for the sake of attaining self-sufficiency.
