The Power token represents the electrical energy generated and consumed within the colony. It is the foundation of the entire resource chain, and is the only resource that can be produced by providing no other resource inputs to the items (Solar Panel Arrays produce it from sunlight reaching the Martian surface, and the Fission and Megapower reactors have enough radioactive material to last for a long time).
This electrical energy is used to power life support, equipment and machinery, along with all vehicles. There is a network of sub-surface power cables connecting the colony, coupled with battery storage facilities for times of low Power production.
Martia tokens can be staked to receive a share of the 3,000 Power tokens awarded each hour.
