Description
Planetary Heat Exchange moves excess energy between regions to soften severe climate and industrial extremes. Open marginal systems early, then turn fragile settlements into durable and populous worlds.
Benefits
Population growth Empire-wide+5%
Class B systems Colonization access
Habitat Restoration Terraforming project
Climate Conditioning Terraforming project
Atmospheric Thickening Terraforming project
Orbital Mirror Deployment Terraforming project
Tectonic Stabilization Terraforming project
Strategy notes
Planetary Heat Exchange develops the Terraforming discipline within Expansion and Terraforming. Open marginal systems early, then turn fragile settlements into durable and populous worlds. Its immediate value is +5% population growth. The principal counterpressure is that planetary programs mature slowly and expose expensive frontier infrastructure before it can defend itself.
Player hints
This is a major commitment. Secure its required resources and protect the supporting infrastructure before assigning Critical priority. Favor this technology when its Terraforming benefits reinforce your current economy, fleets, or frontier. Pause the branch if its expected RP per tick is too diluted or its resource costs would stall higher-priority projects.
