Deep Core Heatsinks (often referred to as "Ducks" by affectionate technicians) absorb heat and distribute the excess energy throughout a series of wells drilled deep into the planetary crust. Massive refrigeration units cool and prepare the heat for eventual dissipation. The presence of a Duck increases the Temperature Class Comfort Zone to 150 degrees on worlds that are hotter than your homeworld. Deep Core Heatsinks consume massive amounts of Power, eating up a whopping 25,000 per turn.
