Compact Fusion Reactors is a technology on the Exploration and Expansion technology tree with a research cost of 130 . It unlocks one Empire Improvement and one Colonization option, requires research in Xenobotany or in Arid Epigenetics, and allows further research in Applied Casimir Effect and Improved Thermodynamics.
"While great leaps forward in fusion technology are on the horizon, the ability to miniaturize and simplify existing fusion technology also provides practical rewards."
Advanced Magnetics DriveEdit
"As the understanding of electromagnetic forces improves, higher energy magnetic coils and more powerful control systems are used to increase the speed of the basic string induction drive."
- -100% on Population growth on Star System
"The ability to colonize Arctic-type planets is largely thanks to the invention of portable fusion systems. Transportable, easily installable, and largely maintenance-free fusion systems permit explorers and colonist to survive previously deadly environments."
- Remove the colonization penalty on that planet type
Sowers can always colonize any planet type, but suffer a penalty until they research the appropriate technology.
