A low or no pollution engine (20) is provided which collects air from a surrounding environment. After removing a portion of the nitrogen, the remaining gas is primarily oxygen, which is routed to a gas generator (70). The gas generator has an igniter and inputs for the high pressure oxygen and a high pressure hydrogen-containing fuel, such as hydrogen, methane or a light alcohol. The fuel and oxygen are combusted within the gas generator, forming water and carbon dioxide with carbon containing fuels. The combustion products are then expanded through a power generating device (48). The combustion products are then passed through a condenser (80), and then is routed back to the gas generator. The carbon dioxide is compressed and cooled so that it is in a liquid phase or super critical state. The dense phase carbon dioxide is then further processed from which return of the CO2 into the atmosphere is inhibited. |
