A system and method by which energy from ocean waves is converted into hydrogen, and that hydrogen is used to manifest electrical and mechanical energies by an energy consuming device. A portion of the generated electrical power is communicated to water electrolyzers which produce oxygen and hydrogen from water as gases. At least a portion of the generated hydrogen gas is transferred to a transportation ship via a hose-carrying, remotely operated (or otherwise unmanned) vehicle, and subsequently transferred to an energy-consuming module or infrastructur, where a portion of the hydrogen is consumed in order to manifest a generation of electrical energy, a mechanical motion, and/or a chemical reaction.

A vehicle propulsion system comprises at least two motors. Combustion occurs upstream of a first motor, and a second motor is downstream of said first motor. The first motor is a turbine that drives a primary propulsion element to effect propulsion and a compressor to effect compression. The second motor is an expansion device whose incoming gases arrive from said first motor. The first motor and the second motor intercommunicate energy via electrical, electromagnetic, and/or mechanical means. Pressurized gases that result from said compression, combustion, or both are rendered or wastegated for auxiliary usage such as aerial thrust, vertical takeoff and/or vertical landing, near-vertical takeoff and/or near-vertical landing, pneumatic storage for hybrid drive, pneumatic lift and/or drive for towing and/or raising another vehicle, aerial vehicle steering, aerial vehicle pitch stabilization or manipulation, aerial vehicle roll stabilization or manipulation, and/or aerial vehicle yaw stabilization or manipulation.

The packaging machine including the bag maker, a traction device and a heat sealing device are respectively arranged above the bag maker, and a width adjustment device adjusts the distances between different sub bottom plates in a front bottom plate and a rear bottom plate by using a leadscrew and slide block mechanism, and then adjusts the width of a bottom plate. The leadscrew and slide block mechanism is used as the width adjustment device of the automatic width-adjustable noodle packaging bag shaper system, and four bottom plates are respectively fixed to the width adjustment device, so the leadscrew and slide block mechanism in operation is accurate in range of adjustment, is suitable for various widths of packaging bags, and has very important significance for the three-dimensional shaping effect of the packaging bags.

The present invention relates to a method and system for increasing power output and enhancing efficiency of an internal combustion engine, which comprises: cooling exhaust gas of the engine in a recuperating heat exchanger by transferring heat to stored air; compressing the exhaust gas to a pressure requisite for admission into the engine utilizing a compander module powered by expanding previously compressed and stored air in an expander without parasitic power consumption; mixing the exhaust gas with expanded air; and cooling or heating the exhaust gas to a suitable temperature in a final trim cooler or heater and supplying the exhaust gas to the engine at a pressure requisite at an admission point, without the need for additional compression and concomitant parasitic power consumption needed for exhaust gas recirculation. Extra electric power output and higher thermal efficiency is facilitated by using the excess power generation from the compander in a synchronous AC generator.

A system in a water body uses buoyant force of gaseous Hydrogen and Oxygen to generate electrical power with one or more turbines that includes power resulting from the buoyant force while transporting the Hydrogen or Oxygen to a higher elevation, without loss of electrons, for conversion to electricity at the higher elevation. Conversion of Hydrogen and Oxygen to water through a Hydrogen Fuel Cell or by burning at the higher elevation may generate additional steam power, hydropower, or purified water. Portable submersible modules may transport the system below or above the water to and from the base of a plumbing portion of the system. The amount of gaseous fuel energy available at the higher elevation is not detrimentally impacted by the generation of electricity by the turbine.
