Food

High yield, low resource, climate resilient.

Food production is approached as a biological system integrated with water, air, and energy for predictable output in harsh conditions.

The problem

Food fails when water, power, and climate do.

Traditional agriculture assumes stable climate and abundant resources. In constrained environments, yield volatility becomes a critical failure mode.

Research focus

Resilient food output without seasonal dependence.

  • Crop genetics for high yield per unit of energy
  • Low-water and brackish-tolerant cultivation
  • Multi-crop co-cultivation in controlled environments
  • Vertical and modular agriculture for dense or remote sites
  • Aquaculture integration to close nutrient loops
Inside the loop

Grow, convert, return.

Food is the least-closed loop in every remote operation, on or off Earth — the ISS now recovers ~98% of its water yet recycles 0% of its food. Heliphere treats food production as biological infrastructure: the same organisms that grow calories also scrub CO₂, release O₂, transpire clean water, and digest waste.

Food loop process chain: four cultivation sub-loops feeding three conversion sub-loops, with labelled inputs from the water, materials, energy, and air loops above and outputs to crew, materials, water, and air below Mass flow Power Irrigation water + N/P/K from Water loop Compost + biochar from Materials loop Electricity — LEDs, pumps from Energy loop CO₂-enriched air from Air loop Hydroponics / aeroponics Nutrient mixing + EC/pH dosing LED growth to maturation Harvest + solution recapture Soil + compost beds Media prep — compost + biochar Drip irrigation + fertigation Harvest + media regeneration Aquaponics (RAS) Fish feeding + solids removal Biofiltration (NH₃ → NO₃⁻) Plant uptake + fish harvest Algae photobioreactor CO₂ sparging under LEDs Membrane harvest Dewatering + drying Inedible biomass + waste Food scraps from Crew CO₂ + H₂ from Air + Energy Insect protein (BSF) Larval bioconversion — 12-14 days Larvae / frass separation Kill step, drying, milling Fungal cultivation Substrate steam pasteurisation Colonisation + fruiting Spent substrate to compost Precision fermentation Gas or sugar feedstock prep Sterile fed-batch fermentation Harvest, drying, formulation Fresh harvest → Crew veg, fish, staples Larval protein → Crew + fish feed Frass (N-P-K) → Materials Mushrooms → Crew Spent substrate → Materials (compost) Protein + lipids → Crew Spent broth → Water loop O₂ + vapour → Air loop

The seven food sub-loops as one process chain: cultivation systems (top row) feed the crew and the air loop, while inedible biomass and waste streams cascade into conversion sub-loops (bottom row) that turn residues back into protein, mushrooms, and fermented ingredients. Every stream is coloured by the loop it exchanges with. Electricity is drawn once for clarity — every sub-loop draws from the energy loop.

System connections

The food system does more than feed people.

A well-designed cultivation system is simultaneously the air purification system, a major water recycler, and the primary organic waste processor — delivering multiple life-support functions from one biological process.

  • → Air — O₂ from photosynthesis; biological CO₂ scrubbing at no additional cost
  • → Water — 70–95% of absorbed water returned as vapour via transpiration
  • → Materials — inedible biomass, roots, and processing waste as feedstock
  • ← Air — CO₂ routed directly to plant canopies as crop fertiliser
  • ← Water — clean irrigation water and dissolved nutrient delivery
  • ← Materials — compost and biochar returned as soil amendment
Shipped as standard modules

The reference architecture packs each food sub-loop into standardised 20 ft ISO containers — one physical interface, one control plane, deployable by road, rail, sea, or launch vehicle.

Fold-out Greenhouse

Ships as a 14 m² box, grows as a ~120 m² tented canopy.

Sunlight does the work grow lighting otherwise has to — the single largest energy line in the food loop.

Development focus

Crops designed for the loop, not the field.

Controlled Environment Agriculture

Decoupling food from climate

Fully enclosed growing systems eliminate dependence on seasonal cycles, weather, and soil. Precise control of light, temperature, humidity and CO₂ enables continuous, predictable food output regardless of external conditions.

Hydroponics & Aeroponics

Growing without soil

Nutrient-film, deep-water culture and aeroponic systems deliver water and minerals directly to roots. These approaches reduce water use by up to 95% compared to soil cultivation and integrate directly with closed-loop water and nutrient management.

Aquaponics

Fish and plants in a closed loop

Integrated fish and plant systems see fish waste providing nutrients for crops while plant roots clean the water for fish. These systems produce both protein and vegetables from a single water volume, closing the nutrient cycle without external fertiliser inputs.

Algae Cultivation

High-yield micro-crop

Algae cultivation systems simultaneously produce protein and lipids for food, consume CO₂ from the air loop, and generate oxygen as a continuous byproduct. Algae offer the highest biomass yield per unit area of any known crop.

Crop Genetics

Optimising for the loop

Crop varieties are selected and developed for high yield per unit of light, water and nutrient input. The focus is on cultivars that maximise caloric and nutritional output in artificial environments while minimising waste biomass and resource consumption.

Insect Protein

Efficient protein conversion

Insect farming systems convert organic waste streams into high-quality protein and lipids. Insects convert food waste to edible biomass at significantly higher efficiency than conventional livestock, closing the loop between food waste and food production.

Precision Fermentation

Biology as a factory

Microorganisms are used to produce proteins, fats, vitamins and flavour compounds without conventional agriculture. Fermentation systems run on simple feedstocks, operate in small footprints, and integrate directly with organic waste and CO₂ streams from other loops.

Biochar & Soil Biology

Rebuilding biological fertility

Biochar production from food waste and its application as a long-lived soil amendment builds fertility from within the system. Biochar improves water retention, supports beneficial microbial communities, and sequesters carbon — closing the nutrient cycle without external inputs.

Beyond Earth

The same loop, off Earth.

On the Moon and Mars, food flips from the most open loop to the anchor of closure. There is no usable soil — Martian regolith carries plant-toxic perchlorates — so hydroponics, bioreactors, and insect and fungal conversion must carry the entire diet, with every gram of nitrogen, phosphorus, and potassium recovered from urine and waste streams rather than imported. Lighting becomes fully artificial: the 14-day lunar night and months-long Martian dust storms rule out reliable sunlight, making the ~90–140 kWh per person-day photosynthetic energy bill the single largest driver of the energy loop and pushing light-free routes — gas fermentation of protein from CO₂ and hydrogen — from novelty to necessity. In exchange, the crop modules become the habitat's primary biological air and water regenerators, and every kilogram of food grown in situ displaces launch mass costed at thousands of dollars per kilogram.
