Here we explore how we might generate power on Titan (Saturn, 9.5 AU). - **Nuclear fission (primary workhorse):** Compact 100 kWe–multi-MWe reactors give reliable baseload for industry and electrolysis. Waste heat is easy to dump into the frigid environment. - **Wind power (surprisingly good):** Titan’s air is \~4–5× denser than Earth’s. Even modest 2 m/s winds yield \~7 W/m² of rotor sweep (practical), with >100 W/m² in gusty events—scalable with tall masts or tethered kites. - **Solar (weak at surface):** Top-of-atmosphere flux at Saturn is \~15 W/m²; haze slashes surface yield to low single-digits W/m²—usable for distributed loads, not for industry. - **Combustion / fuel cells:** Hydrocarbon-rich environment lets you run **methane fuel cells** or even engines **if** you make O₂ from water ice. Useful as peakers or mobile power. - **Hydro/tide:** Small, local opportunities on seas (low head, modest tides) to complement the grid.
# Propellant & building Crack water ice to O₂, use **native CH₄** → **methalox** (storability far better than LH₂). Abundant organics enable polymers, composites, solvents; dense air eases aerostats and turbine logistics.
