A gas generator includes an oxygen inlet, a gaseous fuel inlet, a water, steam and / or CO2 inlet and a water borne fuel inlet. The water borne fuel is combusted within the gas generator along with the oxygen and the gaseous fuel to produce products of combustion including substantially only steam and carbon dioxide. The water borne fuel can be a water fuel solution, emulsion, mixture or other combination. The water borne fuel can either provide only a small portion of the total fuel into the gas generator or provide up to all of the fuel input into the gas generator. The combustion products are discharged from the gas generator and then power is extracted, such as through a turbine. The products of combustion can then be separated, such as within a condenser. Carbon dioxide is thus removed and can be readily sequestered away from the atmosphere to avoid emission of greenhouse gases.
