fuel without further conditioning while producing very high thermal efficiency and full rated power in comparison with engine operation on gasoline or diesel fuel this is a particularly important advantage for remote operation and to bring fuel and power to depressed economies where it is prohibitive to import fossil based fuels preferential production of hydrogen provides thermodynamic advantages based on faster fuel combustion wider air fuel ratio combustion limits and with smartplug operation the engine operates essentially without throttle losses these thermodynamic advantages provide much higher brake mean effective pressure or u201c bmep u201d for the same heat release in comparisons with gasoline or diesel fuel as shown in table 11 it is possible to actually clean the air with an engine generator running on hydrogen characterized fuel produced from landfill or sewage organic wastes the ambient air was cleaned by operation of an engine that is compared in operation between hydrogen and gasoline substantial amounts of carbon dioxide are produced along with hydrogen by operation of electro conditioned anaerobic digestion of organic wastes economical separation of hydrogen from the carbon dioxide is needed for fuel cell applications for increasing the storage density of hydrogen and for increasing the value of hydrogen produced such separation is provided by the embodiment of fig1 this embodiment also serves the purpose of providing for utilization 25 of the carbon dioxide for various purposes including use in greenhouses or hydroponics and is an important aspect of the invention the solubility of carbon dioxide in water is about 21 6 volumes of.
