Shameless self-promotion here; but I think it meets your requirements.

Hexafarms (https://hexafarms.com/ )- an indoor farming startup which can match a throughput that will enable us to grow food in the urban pockets at an efficiecy between 10-200x (depending on what you're meauring).

The website is a bit flashy and not very detailed. Also it is only this month I'm gonna be working ~full time hours on it. Here's why it's radical:

* A empty single-floor 2000 sq. ft. space can produce ~200k KGs of produce. Hence also the idealization of distributed and small farms and not those 10-storey robot driven ones. * Possibility of growing 'crafted-produce', say low-sodium lettuce for diabetes, bitter and juicy lettuce for kids (apparently they like it), very high oil content mint plants so you get same amount of mint oil from half the weight. * All of this greatly affects (and positively) the current supply chain. * It's heavily data driven. And this is not just because it's cool. Think of it as openAI GPT, but for X produce.

This is rad but want to hedge that this sort of farming is only viable for some leafy greens and herbs. The site for instance only talks about lettuce which is rad but nutritionally void.

The sun is a lot cheaper at scale than LEDs unfortunately.

It may solve some specific urban farming issues but we haven’t got endless sunlight beat yet.

Do you have any images of how the setup would look? Also:

Per which unit of time?

Thanks for fixing the link. That's another little known thing- an average field (max) produces three harvests of lettuce. I don't have actual data, but based on my experimentations I think a realization of 13-20 harvests is possible; actually there's literature on this as well. How exactly? Just a basic application of the queuing theory. A lettuce needs to sit in the main hole for max 20 days. Before that, within the same 2k sq. ft. that I mentioned, keep it in separate 'incubator'space which will take much less volume.

In the coming weeks I'll add pictures too.

That's exactly the kind of stuff that I'm into. I'm not an authority but that sounds hella radical.
