a DC power source in selective electrical connection with the DC electric motor to enable user control of the DC electric motor; a power generator electrically connected to the DC power source and capable of charging the DC power source; and an internal combustion engine connected to operate the power generator, the internal combustion engine including a mixing block having a gaseous fuel source to selectively provide a gaseous fuel/air mixture to the internal combustion engine upon detection of at least a partial vacuum in a cylinder of the internal combustion engine, where the detection of at least a partial vacuum in a cylinder causes gaseous fuel to enter the mixing block. ### Claim 2 (depends on 1) The machine as set forth in claim 1, further comprising a transmission mechanically connected to the DC electric motor at a first end and mechanically connected to a drive train at a second end. ### Claim 3 (depends on 1) The machine as set forth in claim 1, further comprising a source of gaseous fuel. ### Claim 4 (depends on 1) The machine as set forth in claim 1, where the gaseous fuel consists essentially of hydrogen. ### Claim 5 (depends on 1) The machine as set forth in claim 1, where the power generator comprises an AC generator electrically connected to an inverter converting AC power to DC power. ### Claim 6 (depends on 1) The machine as set forth in claim 1, where the power generator comprises an alternator providing DC power. ### Claim 7 (depends on 1) The machine as set forth in claim 1, where the vehicle comprises an automobile. ### Claim 8 (depends on 1) The machine as set forth in claim 1, where the vehicle comprises a mass transit vehicle. ### Claim 9 (depends on 1) The machine as set forth in claim 1, where the vehicle comprises a fork-lift. ### Claim 10 A machine comprising: a vehicle body for human transport on land; an electric motor operably disposed in connection with the vehicle body, the electric motor operably connected to a power source where the electric motor is selectively controlled through a user control in the vehicle body; a charger electrically connected to the power source and capable of charging the power source; and a hydrogen fuel control system including a hydrogen fuel source that selectively provides a hydrogen fuel and air mixture to an internal combustion engine physically separated from the electric motor upon detection of a condition in the internal combustion engine, where the internal combustion engine operates the charger, the internal combustion engine including a mixing block having a hydrogen fuel source to selectively provide the hydrogen fuel and air mixture to the internal combustion engine upon detection of the condition in the internal combustion engine. ### Claim 11 (depends on 10) The machine as set forth in claim 10, where the condition in the internal combustion engine comprises a partial vacuum.
