An ore tank is a unique class of tanks that are empty by default in the Editor. They are used to store ore mined from a planetary body using a resource harvester, instead of propellant for the engines. The ore has no serious financial value, but can be used to produce fuel with a converter and vast amount of electricity. These tanks store the ore temporarily from extraction until conversion. Ore tanks were introduced in version 1.0. As of version 1.0.5 there are three Ore Tanks, the Large Holding Tank, the Small Holding Tank and the Radial Holding Tank.
With the buoyancy system overhaul in 1.0.5, an unorthodox use for the ore tanks has emerged: they are denser than water, which makes them suitable ballast for submarines.
