Alternative Fuel Converter

Your ship is equipped with an alternative fuel converter which allows the conversion of materials to a potential fuel source. Over the course of 10 minutes, a crewmember can make a constitution (Regulation) check (DC = 10 or half the number of days since the ship's last refueling, whichever number is higher). On a success, the ship recovers one unit worth of fuel. This feature can be used a number of times equal to your ship's tier (a minimum of once). All expended uses are regained when the ship undergoes refitting.
