Improved Thermodynamics is a technology on the Exploration and Expansion technology tree with a research cost of 300 . It unlocks one Star System Improvement, requires research in Compact Fusion Reactors or in Sustainability, and allows further research in Baryonic Shielding and Adaptive Colonies.
"Useful in the analysis of heat and radiation exchange in everything from fire to steam engines to black holes, careful management of the exchange of energy, heat, and work on a nano-scale level opens the door to highly efficient miniaturized engines or condensers."
"The creation of buildings that absorb various forms of passive energy (ambient heat, radiation, light, etc.) and convert it into usable energy creates a boom in inexpensive, temperature-indifferent housing."
