CO2 to O2 Conversion

ATMOSPHERIC TERRAFORMING // OXYGEN RECOVERY

MOXIE ELECTROLYSIS REACTION
2CO2 → (Heat + Electricity) → 2CO + O2
Solid Oxide Electrolysis

Using ceramic membranes to pull O atoms from CO2 molecules at high temperatures. This was successfully tested on Mars via the MOXIE instrument.

Yield: High
Photosynthetic Algae

Deploying floating bio-reactors in the Venusian clouds (50km) where CO2 and sunlight are abundant. Algae consume CO2 to release O2.

Yield: Sustainable
Sabatier Integration

Combining CO2 with imported Hydrogen (H2) to create Water (H2O) and Methane (CH4), then splitting the water to extract Oxygen.

Yield: Dual Purpose

The Scale of Challenge

Venus has roughly 4.8 x 10^20 kg of CO2. Converting even 10% of this into Oxygen would require more energy than humanity currently produces in a century.
