In summaiy, diesel fuel with veiy low to no sulfur content is now possible with chemical and technological advances. Along with catalytic converters, electronic fuel systems, and sensors, the diesel engine for the new millennium will he capable of complying with ever more stringent EPA exliaust emissions. The diesel engine will continue to sei"ve as the main global workliorse for all of the many thousands of different applications of its power cycle.

These new fuel-desulfurization processes reject little heat at low temperatures. If a fuel gas is to be used in a combustion or if the gas is to be subjected to further processing at high temperature—e.g., CO shift —the new desulfurization processes have the advantage that the heat exchange required to cool the gases to a low temperature sulfur-removal step is eliminated. The processes are well-suited to schemes which produce a clean fuel gas to be burned at high pressure in an advanced power cycle. Indeed, the concept of the new processes was a result of a search... 

The scheme of Figure 8 is obviously more attractive if one needs high level heat, available to the heat-transfer surfaces shown in reactor A, as well as need for H2. This scheme would permit production of byproduct H2 in future power stations which use some combination incorporating pressurized fuel gasification, fuel-gas cleanup, and an advanced power cycle. 

The AHTR has a higher potential efficiency than the GT-MHR at the same reactor eoolant exit temperatures, because delivery of most of the heat at near-constant high temperatures allows the use of more-efficient Camot-like power cycles. The benefit of these advanced cycles is increased efficiency, resulting in up to 20% increased electrical output for the same thermal power. The cost of this improvement is some increased system complexity. Molten salt coolants present the most promising approach to take advantage of this potential benefit.

The field of propulsion deals with the means by which aircraft, missiles, and spacecraft are propelled toward their destinations. Subjects of development include propellers and rotors driven by internal combustion engines or jet engines, rockets powered by solid- or liquid-fueled engines, spacecraft powered by ion engines, solar sails or nuclear reactors, and matter-antimatter engines. Propulsion system metrics include thrust, power, cycle efficiency, propulsion efficiency, specific impulse, and thrust-specific fuel consumption. Advances in this field have enabled hiunanity to travel across the world in a few hours, visit space and the Moon, and send probes to distant planets.
