Fuel supply system

A method for converting a fuel into mechanical energy and/or electric energy, the method comprising:

• changing a phase of fuel held in a fuel supply in a liquid phase to a gas or vapor phase;
• directing the fuel in the gas or vapor phase through one or more heat exchangers;
• cooling an operating temperature of an operating fluid flowing in one or more operating fluid circuits using the fuel in the gas or vapor phase and the one or more heat exchangers;
• and
• generating one or more of mechanical energy or electric energy using an energy producing assembly by directing the fuel in the gas or vapor phase from the one or more heat exchangers to the energy producing assembly.

A fuel supply system, comprising:

• a fuel supply configured to hold a cryogenic fuel in a liquid phase;
• a blower configured to change the fuel from the liquid phase to a gas or vapor phase in the fuel supply by directing ambient air through one or more conduits extending into the fuel supply;
• an energy producing assembly configured to generate one or more of mechanical energy or electric energy by consuming the fuel from the fuel supply while the fuel is in the gas or vapor phase;
• one or more operating fluid circuits coupled with the energy producing assembly, the one or more operating fluid circuits configured to manage an operating temperature of the energy producing assembly by directing operating fluid into and out of the energy producing assembly;
• and
• one or more heat exchangers configured to control an operating fluid temperature of the operating fluid in the one or more operating fluid circuits using a reduced temperature of the fuel in the gas or vapor phase prior to directing the fuel into the energy producing assembly.
