Abstract:
There is disclosed a hydrogen powered internal combustion engine (12) having cylinders (22) for driving crankshafts (28). The crankshafts are configured to drive water pumps (32) which are for pumping water into engagement with drive faces (58) of a drive water wheel (44). This water wheel is connected to, and drives, a main propulsion shaft (30) which produces the main propulsion of the engine, for example, for powering a vehicle. One or more ancillary water wheels (46, 48) are driven by the pumped water and are connected to generators for producing electric current for powering an electrolysis device (78) which produces hydrogen that can be used as fuel by the engine.

The fuel supply system may include a water recovery subsystem (6) coupled to an exhaust output (9) of the internal combustion engine, the internal combustion engine producing an exhaust including water vapor and CO 2 , the water recovery subsystem comprising a filter (13) for removing CO 2 , from the water vapor.
Abstract:
The present invention concerns apparatus, kits and methods for converting ICE vehicles to run on hydrogen fuel. Certain embodiments of the invention may comprise HIPAs (hydrogen injection port adaptors), hydrogen gas manifolds and hydrogen fuel sources. The HIPAs are designed to replace the spark plugs in internal combustion engines and may comprise a hydrogen input tap, hydrogen channel, spark producer and/or feedback sensor. In some embodiments, a computer and/or CPU may electronically control the timing of hydrogen ignition. In other embodiments, a mechanical timing system may supplement or replace electronic control of ignition timing. In various embodiments, any source of hydrogen fuel may be used. In preferred embodiments, the hydrogen fuel source comprises doped sodium alanate compositions. The hydrogen fuel may be packaged into cassettes or other modulara storage systems. Cassettes may be inserted into Decom units to provide hydrogen fuel to the vehicle.

Abstract:
Systems and methods involving monopropellant and hypergolic powered proportional actuators that may be used in applications such as robotics. A blowdown tank delivers fuel to a reaction site, produce gaseous products. Those gaseous products are transported to a pressure reservoir or directly to the actuator. The gaseous products are controllably introduced into the actuator to actuate a piston. The piston may be used to power a host of devices including robots.
Abstract:
A system (10) and method for converting light hydrocarbons into heavier hydrocarbons, such as with a Fischer-Tropsch process, are provided that use a gas turbine (16) and that uses at least two different sources (14, 44) of compressed oxygen-containing gas (28) for the preparation of synthesis gas (60). The system and method may also include a steam turbine (300) powered by process steam, along with the gas turbine, to provide additional power to produce the compressed oxygen containing gas.
Abstract:
An apparatus for feeding hydrogen into an intake (11) of an engine (1), including: an air inlet (23); a hydrogen inlet (21); a mixing chamber (20) for generating a fuel mixture from hydrogen and air introduced from the inlets, the chamber being adapted to couple to the intake of the engine, for introducing the fuel mixture thereto; and control means (26) for controlling airflow through the mixing chamber. The control means may include an air speed control for varying an effective cross-section of air flow through the apparatus.

Abstract:
A system for converting hydrogen into useful work comprising a combustion chamber, a source of working fluid, an accumulator, a propulsion system, and a control valve. A mixture of hydrogen and oxygen is ignited in the combustion chamber to act, directly or indirectly, on the working fluid to pressurize the working fluid. The accumulator is operatively connected to the combustion chamber such that pressurized fluid within the combustion chamber flows into the accumulator. The propulsion system converts pressurized connected between the accumulator and the propulsion system to control a flow of pressurized working fluid from the accumulator to the propulsion system
