A zero emission generation system uses a direct current electric motor (201) driving an electric generator (301) to provide inverted alternating current to a load. The motor draws its electrical energy from two deep cycle direct current batteries (101 and 102), one or the other of which is alternatively switched into a motor drive circuit with the motor. The other of the two batteries is disposed in a recharge circuit which includes an alternator (401), mechanically powered by the direct current motor (201). Accordingly, while one battery is supplying power to the motor and generator, the other battery is being recharged towards capacity. A comptroller (501) controls the switching between the two batteries and regulates recharging rates and extent by regulating the alternator field amperage draw and/or the alternator output to the charging circuit of the system. Further relays may be used to form a safety circuit to prevent both batteries from being removed from the motor drive circuit simultaneously. By switching the batteries between the motor drive circuit and the recharge circuit, the present system remains effective over a number of partial battery cycles, providing a sustained supply of electrical power to a load over a prolonged period of time. Further, such a system provides a built-in reserve should one or the other of the batteries become exhausted, inoperative, or otherwise require replacement.
