Vespene Tank

Cost of the 1st level:

10 00010 000CRP 2
Huge cylinders for the storage of produced gas. They are usually located near the spaceport. The larger they are, the more Vespene they may save. Each new level of infrastructure development increases the capacity by 1%. If capacity is filled, the gas production is stopped. Gas that doesn't fit into storage is lost at a rate of 4% per day when the overflow is up to 5%, and at a speed equal to the overflow percentage per day otherwise (with a maximum of 10%).
Storage capacity can be increased by hiring Officer Storekeeper. Facility capacity can be increased by the capacity of the fleet at the facility (if hired Storekeeper), and by the capacity of the Colony Ship (regardless of the presence of Storekeeper).
