Rethinking meal possibilitiesin the 21st century.

We have decided to aim against cold climates. The heat they need, the taxes they carry and the light they lack all stack against a greenhouse. Every winter month is paid for twice — once in energy to hold temperature, and again in supplemental lighting to make up a deficit the sky will not cover.

It is simply more reasonable to grow in the south, where the climate does most of the work for nothing, and then solve the distance instead of fighting the weather.

Distance is a solvable problem. Electric trucks and self-driving automation turn the journey into a scheduling exercise rather than a cost centre, and the marginal cost of a kilometre keeps falling while the cost of a cold winter does not.

The plan is to ship an average of 3 tons per day from the south to the north — produce grown where growing is cheap, delivered where the people are.

Our focus is automated olive oil and vegetable production — crops that suit a passive climate, reward automation, and carry no commitment beyond the season.

Growing the food is only half of it. Produce still has to become a meal, and that step is where cost and convenience usually reassert themselves.

So the growing is paired with machines that cook the produce into water- and nutrient-dense, pesticide-free food, finished and ready to eat.

The target is $1 to $2 per meal. Not per kilogram of raw vegetables, but per meal on the plate — which is the only number anyone actually compares.

If the protein is not coming from an animal that has to be culled, it has to come from somewhere. It is better for us to focus on fish and shrimp, which live symbiotically with the aeroponic systems and take up very little space doing it.

The pairing works in both directions: the water carries nutrients the plants want, and the plants clean the water the animals need. Neither side is a by-product of the other.

They give high-quality, genuinely delicious protein, and they are relatively easy to automate — no pregnancy, no dry period, no long-term commitment attached to an animal that stops producing.

Cooked at low flame with olive oil — considered the best way to prepare it — that is the whole meal: protein and vegetables, both grown on the same site.

Shrimp is the part of the system we are actively building automation for. It is under development, not something we are running at scale.

The target is $2 per kilogram of shrimp, reached through automation.

Dense planting is what makes a small footprint productive, and it is exactly what makes harvesting hard. Conventional picking robots are bulky: they need aisles, and aisles are wasted growing space.

Ours is deliberately slender — a slim, articulated arm that slides between crowded stems and canopy without bruising leaves or knocking unripe fruit, reaching into the plant rather than pushing it aside.

At the tip, a soft gripper closes on the fruit, judges when it is ready and separates it with the same gentle twist a person's hand would use. Fruit arrives unmarked, and the plant is left intact to keep bearing.

Because the arm is thin, the growing beds can stay tight. The technology earns its place by taking away the reason to leave empty space.

Hydroponic fodder units are sold to dairy farmers at prices that never pay back — racks of steel, powered trays and control systems, for grass. We took the cost apart and rebuilt the machine around rope.

Rope carries the trays, sets the spacing and takes the load that expensive framework used to. It is cheap, it is repairable anywhere in the country, and it removes most of the metal from the bill of materials.

The result grows 500 kilograms of fresh grass every week — a steady supply of green feed regardless of the season outside or the state of the monsoon.

The whole thing costs $500 per machine, and that figure is honest: it includes the growing room and the grass, not just the frame. A dairy farmer can see the payback without a spreadsheet.

The only way to make genuinely local farming work is to produce your own fuel, and the only practical route to that is pairing the greenhouse with animals: their waste produces methane, and the milk pays for the animal. On paper it closes.

In practice, the animal must give birth, and both the animal and its calf are a long-term commitment — one that outlasts any single season's plan.

To stay open to the possibility, we invested in hydroponic fodder, which cuts silage and fodder operations down to almost nothing. That leaves a minimal operation built around milking equipment alone, and it cuts the land requirement sharply.

Pregnancy, milk harvesting and feeding can all be managed. Sourcing hay and storing it is possible. The hard part is feeding the animal once it stops producing milk — an animal that still eats every day and returns nothing.

That requires culling, and despite the advantages of meat and dairy, we are not able to support that. It is the one part of the system we cannot bring ourselves to operate.

We are also unconvinced it is necessary. The assumption that serious physical performance requires meat does not survive contact with the people actually doing it.

Frank Medrano is a vegan calisthenics athlete whose entire discipline is strength relative to bodyweight — planches, human flags, one-arm work. There is nowhere to hide in that sport: either the muscle is there or the movement does not happen.

Lewis Hamilton won world championships in Formula One after going vegan, in a cockpit that runs well past 50°C, under sustained cornering loads several times bodyweight, for two hours with no substitution and a weight limit that punishes every spare kilogram.

Alex Honnold free soloed El Capitan on a vegetarian diet — four hours of continuous climbing with no rope, where a single failure of grip strength or concentration is fatal. Nobody attempts that undernourished.

Three different demands — raw strength, heat and endurance, and strength-to-weight under total consequence — and none of them required an animal to be culled.

So we have decided to move away from dairy personally, to support dairy animals with hydroponic fodder instead, and to put our own effort somewhere we can be certain of the outcome.
