For the purpose of model-based analysis and control design, a dynamic physics-based model for free electric generator is developed in this paper. The physics-based model contains 17 states, which include piston dynamics, alternator current, runners and cylinder gas filling dynamics and thermal dynamics. Homogeneous charge compression ignition (HCCI) combustion is employed for better efficiency and reduced emissions, whereas spark ignition (SI) combustion can be used for quick start of the FPEG and higher power demand. Equipped with electric mechanical valves (EMVs) and direct injection, the free-piston engine generator is deemed to achieve optimized and clean combustion. Key features in this dynamic model include the runners and cylinder filling dynamics and cycle-to-cycle coupling between the piston motion and combustion process. Simulation results demonstrate that during a transition from SI to HCCI mode, the scavenging process needs to be properly maintained so as to achieve trapped mass balance between the opposite cylinders.

The disclosed portable water-powered free electric generator unit has a tubular form with opposite open inlet and outlet ends defining a longitudinal flow path for the moving stream water. The tubular form defines a converging venturi terminating at a throat between the inlet and outlet ends. An electric dynamo, having a sealed housing and external driving propeller means, is supported in the flow path downsteam of the throat, with the propeller means at the throat. The inlet end is between 2-5 times larger in area than the venturi throat, to speed up the water passing through the propeller means. The tubular form and housing together define a diverging venturi downstream from the throat, decelerating the water with minimal losses before exiting from the open outlet end. The open outlet end is 1.1-1.5 times larger in area than the open inlet end, whereby the slightly faster surrounding stream water blending with the exiting water at the open outlet end may tend to accelerate the exiting water slightly for added efficiencies.
A submerged reciprocating free electric generator is placed below the ocean surface and creates electric power from the surface ocean swells. The generator coil reciprocates linearly in response to an external force acting on a float by passing ocean swells. A cable connects the float on the ocean surface with the reciprocating coil of the submerged generator. A magnetic field is focussed through the coil as it reciprocates, creating an electromotive force in the coil. The magnetic field is created in such a manner as to provide uniform field of a single magnetic orientation throughout the entire length of motion of the reciprocating coil. The generator includes a base formed on the ocean floor supporting magnetic core having a generator coil movably mounted therein and connected to a float with a cable passing through cable alignment bearings. Electromagnetic windings are mounted at the closed end of the generator magnetic flux core.
Research towards improving the performance of free electric generators has become a great interest nowadays. Today, many applications require the generation of electric power without connection to the utility power system. For this purpose, the generator must be efficient, reliable and lightweight.

This gains significant improvement in efficiency as well as volume and mass reduction. This paper presents a fabrication of a linear electric generator that is capable of generating 5 kW of power. The concept of a free-piston generator and a free electric generator is reviewed. The design and fabrication processes are also covered. Performance evaluation is discussed as well.
Free-piston engine generators (FPEGs) have huge potential to be the principle energy conversion device for generating electricity from fuel as part of a hybrid electric vehicle (EV) powertrain system.
