What is the most volume-efficient way to produce 1000 edible kcal per week at home?

Microalgae bioreacotors seem to be quite efficient. Unfortunately, you can only eat 20g (= 60 kcal) of microalgae (Spirulina, Chlorella, ...) per day at max. So how would you produce the kcal?
It should be very volume efficient so that nearly every guy in Tokio could do this in their flat.

The producers of Spirulina and Chlorella powder recommend 3-5g per day. Most “extreme” study I could find was adults on 19g Spirulina per day for 2 months. The algae can have side effects.

Interesting. The potato box can push 45 kg during harvest time. 1 potato is about 0.17kg and 150 calories. Assuming harvest time is 90 days I get an average of about 450 calories per day from one potato box. Four potato boxes is all you need to survive, and if buckets are more efficient as you say then this figure would be improved.

I've had chickens since 7 years old. They are very easy to keep if you actually have a yard. Average around 1 egg a day from March to August in a temperate climate. Plus each hen over 1 year old will raise around 10 new chicks on average each year.
I had to sell or give away around 50-100 chickens each year or else eat them. You get overrun fast if you keep the coons, dogs/yotes, etc. away.

Kitchen scraps, a little cracked corn we grew in garden, etc. keep them supplemented. Give them a little oyster shell now and then to keep their egg shells strong so they don't break and glass easily.
We would keep around 6-10 5 gallon buckets of water-glassed eggs over the winter. Made a hella lot of bread, cakes, ommelettes, french toast, milk shakes, etc.

It is a big-pharma myth that eating lots of eggs = high cholesterol.
Inactivity and excess sugar, plus genetics = high cholesterol.

The people in charge of medicine, pharma, news media, etc. give the gullible masses false narratives to keep them weak and sick, and fearful. Ignore them if you are smart.

Why would you want to produce something at home? Way to expensive. You know that every dumb ass plant is just cellulose + extra stuff, and that cellulose is essentially just stacked glucose?

Inb4 this derails the thread, but I've been looking into suburban agriculture (for tech nerds to save money or survive collapse) a lot lately, and I honestly think crickets are the missing link to a lot of the discussion here. Maybe /sci/ will be slightly more focused on the technical question to not kneejerk. Crickets don't even need light; you can battery farm them in a way that makes chicken farms look like luxury resorts and they'll do just fine so long as they don't freeze. I'm working out the details of a design that will produce 3000 kcals/day in perpetuity by just supplying spirulina from roof panels and water (the one thing I need to source in bulk) to ~60 growing pods (one cricket life cycle is about two months) with attached dirt pads for the females to lay eggs in before I harvest that pod for the next cycle each day. A little insect animal brutality (lmao) means the whole thing could fit in the smallest model garden sheds available at home improvement stores to stay nondescript and protect from the elements. Tack some insulation to the inside for sound damping and throw in a tiny fuel radiator for heating and it's ready to crank out the flour in a fraction of a percent of the space it takes to make actual flour.

And if I about triple the size, it can feed my chickens instead so I don't have to eat the bug at all. I think this really is the way to go for people without the spare million dollars or so lying around to buy and tend a subsistence farm and who don't want to waste time on pinterest memes. Just turn sunlight into spirulina, spirulina into crickets, and crickets into chickens and eggs. You can then use the cricket frass to grow potato boxes or whatever else doesn't work at scale for some spice in your diet. Works either if you live in a middle-class detached house on your own or if you find a lower-class smaller-scale multiplex or apartment complex with neighbors who will help in exchange for food. High-rises are doomed, though.

I am sceptical about insects since many harbour helicobacter pylori. Mushroom growing is probably safer. And when the substrate is fully spent, you can use it for growing potatoes.

As per OP's question of 140 cal/day yeah it would still be a lot of undigestable raw material. This is really where juicers make a lot of sense.

Something to seriously consider is that insect populations are not fundamentally limited by food availability, but pathogens and parasites instead. But there are plenty of cricket farms out there, so maybe it's not as big a problem as I'm imagining.
For sure, we have a serious problem of wanting food to come from stores and not from our own plants and animals. We could change that with the right products and shifts in mindset.
