1. A vaporizer for heating a liquid-phase fuel, the vaporizer comprising:
a reservoir having a least one wall for containing a heat-conducting fluid;
a heating tube, the heating tube having an inlet end through which liquid-phase fuel will flow and an outlet end through which gaseous fuel will flow; the heating tube being thin-walled such that the exterior surface of the heating tube is in contact with the heat-conducting fluid and an interior surface of the heating tube is in partial contact with the liquid-phase fuel before being vaporized;
at least one electric heating element within the reservoir, the at least one electric heating element being in contact with the heat-conducting fluid to increase the temperature of the heat-conducting fluid to a predetermined temperature, the predetermined temperature being such that the liquid phase fuel entering the heating tube will at least partially vaporize before exiting the heating tube;
a temperature gauge, the temperature gauge having a first portion in contact with the heat-conducting fluid and a second portion to indicate the temperature of the heat-conducting fluid in contact with the first portion;
a controller, the controller operatively connected to the at least one electric heating element to alter the heat output of the at least one electric heating element;
a first flexible hose;
a pressure regulator; and
a one-way valve fluidly, wherein the first flexible hose has a first end fluidly connected to the inlet end of the heating tube and a second end fluidly connected to an outlet of the pressure regulator, the pressure regulator further having an inlet fluidly connected to an outlet of the one way valve which has an inlet connected to a tank containing the pressurized liquid-phase fuel, the one-way valve permitting the liquid-phase fuel to flow in a direction from the tank to the heating tube only.
