Frustrated with the inefficiencies involved in tracking multiple fuel types, Thukker logisticians pioneered the development of prepackaged fuel. In YC 111, after a successful trial period, they converted the Tribe's entire starbase network to use fuel blocks. Capsuleers were forced to wait for this innovation while CONCORD dithered over how to handle the transition period, but were finally granted clearance in YC113.
This is a block of fuel designed for Caldari control towers. Forty blocks are sufficient to run a standard large tower for one hour, while medium and small towers require twenty and ten blocks respectively over the same period.
