I know a guy that set up a food operation in a sea container in Toronto. It was a whole ecosystem of food producing organisms. Fish in the water, herbs like dill, tomatoes, all sorts of stuff. He'd sell it at 4x grocer prices to pricy restaurants near-by. His reasoning in putting it in a sea container was that he could always find a spare place to park it / electrify it with all his friends in the construction industry.

Made enough to live in Kensington Market, which is a hipster / hippy part of Toronto.

I grew up in Iowa, so my fascination with hydroponics is partly from the technical intrigue, but also an egalitarian philosophy.

A locales food security with conventional agriculture is heavily dependent on the quality of their soil, while with hydroponics and derivatives it's more a function of their engineering prowess (and available infrastructure).
