Geothermal energy for Nauvis: steam vents spawn near ore fields - tap them for fuel-free, low-pollution power. Pressurize vent steam to 500C and unlock steam turbines before nuclear. Distill coal under geothermal steam into synthetic crude oil, before finding your first oil field. Richness scales with distance, distant fields are jackpots.

Version: 1.0.0
Date: 2026-07-04
Major Features:
- Initial release.
- Geothermal fissures: infinite steam sources spawning near ore fields. Not every deposit gets a field - richness is rolled per fissure and scales with distance from spawn, like oil.
- Geothermal pump: early-game extractor placed on a fissure, outputs 165°C steam straight into steam engines. Fuel-free, grid-independent, far cleaner than coal boilers.
- Geothermal pressurizer: boosts vent steam to 500°C and unlocks steam turbines long before nuclear. Feeds 4 turbines but draws one turbine's worth of power - plan an independent supply.
- Coal still: distills coal under geothermal steam into synthetic crude oil, before finding any oil field. Deliberately less efficient than vanilla coal liquefaction, and produces waste to flare off.
Features:
- Distilling your first crude oil unlocks vanilla oil processing (with the proper research notification) - the synthetic and pumped routes converge into the normal tech tree.
- The pressurizer and the coal still must be built centered on a geothermal fissure - each fissure hosts a single building, pump or machine.
- The coal distillation technology also unlocks the Flare Stack, so distillation waste can be destroyed as soon as it exists.
- Runtime settings: vent field frequency, field size, spacing, richness range and distance scaling (applied to newly generated chunks).
