Abstract: A method of transducing energy from hydrogen, the method comprising: providing a chamber; maintaining a pressure of 75 psi to 30 in. vacuum within the chamber; injecting fuel into the chamber, where the fuel is hydrogen or a mix of hydrogen and oxygen; and igniting the fuel within the chamber.

Abstract: An energy transducer comprising: a cylinder; a piston within the cylinder connected to a connecting rod extending out of the cylinder and connected to a crankshaft; a chamber within the cylinder defined by the first end of the cylinder and the piston; a direct injector in fluid communication with the chamber and in fluid communication with a fuel tank such that the direct injector is capable of injecting fuel from the fuel tank into the chamber, where the fuel is hydrogen or a mix of hydrogen and oxygen; and an igniter located such that the igniter is capable of igniting the fuel within the chamber; such that ignition of the fuel within the chamber causes an explosion that forces the piston toward the crankshaft, causing the crankshaft to rotate 180°, followed by an implosion that forces the piston away from the crankshaft, causing the crankshaft to complete one full rotation.

Abstract: An energy transducer comprising: a body; a crankshaft; a rotor mounted to the crankshaft and housed within the body such that the rotor may rotate within the body along an axis defined by the crankshaft; one or more chambers located circumferentially around the rotor and angled inward toward the direction of travel of the rotor; an injector connected to the body such that the injector injects fuel into the one or more chambers; and an igniter connected to the body such that the igniter ignites the fuel in the one or more chambers, which causes the rotor to rotate. The fuel may be hydrogen or a mixture of hydrogen and oxygen.
