Quote Inkjet printers can print electronics that FOSS AI can operate to produce electrical power
What do you mean by this? Inkjets are standard paper printers. Why does AI need printed paper?
And what kind of electrical power are you talking about? Like solar and wind?

3D printing is something I have little experience with, but I know size of the printers determines how much you can do with them.
As far as I know, producing photovoltaic cells is still a "globalism"-dependent thing. Harvesting wind is simper, but the returns and scale are kind of tricky.
There is this black kid from the Pacific Northwest who claims to be able to turn plastic-waste into a fuel, but that could all be horseshit who knows.
I know people personally who built bio-diesel busses, and used oil waste from fast-food. But I think there's regulation involved in that shit now.

The concrete super-capacitors is an interesting idea.
Need sources of limestone and clay for cement, carbon-black is a waste-product of fossil fuels so I'm sure there's lots of it being made currently.
Building our infrastructure out of battery is a great idea especially if it's economically viable.
But also:

Risks and downsides of concrete supercapacitors include a trade-off between energy storage and structural strength, low energy density compared to batteries, limited voltage capacity, and a high self-discharge rate. Other challenges involve high resistance, potential for short-circuiting, and unknown long-term performance when used as a structural element.

On Oct 1 they announced they had gotten a 10x performance increase so still promising.
My father's neighbor built and ran a aquaponics greenhouse with fish, and sold the produce for a while. And it's definitely a good way to grow.
Chickens are an incredible thing on their own because they just convert the bottom of the food-chain into readily-available protein, fats, cholesterol with little effort.
It sucks living in an actual neighborhood because I have neighbors behind me who were forced to get rid of their couple of chickens a few years back.
