Abstract: This is an application for a utility patent for a zero emissions turbine, suitable for use in aerospace, power generation, industrial, and marine applications, that runs on the combustion of liquid hydrogen and liquid oxygen and which is cooled by liquid oxygen. It is unique in that its only emissions will be steam, water vapor, pure oxygen, and ice crystals, with no pollutants or greenhouse gases of any kind. It is also unique in that it uses no air intake, no compressor, and simplified shaft and auxiliary drive systems. It has a unique tank and pump system that runs on electric motors and specialized lubricating systems. These turbines can be designed with powerful and reliable operating specifications with greatly reduced fuel consumption and greatly improved power-to-weight ratios.

Abstract: This is a utility patent application for the design of a large marine engine that is also suitable, in different configurations, for smaller marine applications and many different power generation and transportation applications. The drawings show a ten-cylinder two-stroke engine, cylinders with a 110-inch stroke and 36-inch bore, pistons, connecting rods, and a crankshaft. The pistons are driven by the combustion of liquid hydrogen and liquid oxygen ignited by a sparking system. The engine is cooled via coolant passages in the block and head and lubricated by three separate lubrication systems. It uses cryogenic fuel pumps, electronic fuel injection, and electronic actuators regulated by a remote engine control unit. It is close to a zero emissions design, with only steam, water vapor, and extremely minute quantities of burned lubricants and trace air combustion products heading up the stack.
