NOVELTY - Energy conversion apparatus comprise a reaction chamber (4) containing a supply of water (20), anode (14) disposed within water, cathode (16) disposed within water and proximal to the anode, a collector to receive hydrogen escaping from water, photon collection elements to collect photons emitted during arcing between anode and cathode. The anode and cathode selectively adjustably positionable within the water to bring the anode and the cathode sufficiently near for arcing to occur between the anode and cathode.    USE - As a energy conversion apparatus to power engine (claimed), particularly internal combustion engine.    ADVANTAGE - The energy conversion apparatus is highly efficient, and replenishes the carbon rods via a magazine as well as the recycling of the degraded carbon rods. The energy conversion apparatus improves the efficiency of the reaction by collecting the light and heat generated by the reaction and converting those energies to electricity to help sustain the reaction itself. The reaction chamber provides power in several different forms all stemming from a reaction chamber containing water. The energy conversion apparatus relays the captured energy to the power source, thus contributing to replacement of the electricity potential stored by the bank of batteries. The energy conversion apparatus is capable of aiding in its own replenishment of energy via capturing heat and solar energy produced in the reaction chamber. The apparatus provides energy for an internal combustion engine that will burn cleaner than traditional fossil fuel powered engines; and is capable of filtering carbon particles from the water in the system for a clean fuel supply and the recycling of the carbon particles. Arcing between the opposingly charged pairs of carbon rods facilitates the induction of plasma into the reaction environment. Once the plasma exists inside the reaction environment, the use of alternate-pulse width patterns, as well as power and voltage variable modulation, helps to sustain and propagate a plasmatic instance within the reaction environment. This provides the conversion of water by low-voltage electricity into gas at high volume and low pressure. The plasma reaction creates heat and photonic energy inside the reaction environment. The photonic emissions that are released are extremely bright and are collected by photovoltaic panels, which power a high-voltage circuit that helps maintain the charge on the battery as well as helps to power the next cycle of reactions.    DETAILED DESCRIPTION - Energy conversion apparatus comprise a reaction chamber (4) containing a supply of water (20), at least a first anode (14) disposed within the water, at least a first cathode (16) disposed within the water and proximal to the first anode, a collector to receive hydrogen escaping from the water in the reaction chamber, photon collection elements disposed relative to the reaction chamber to collect photons emitted during the arcing between the anode and cathode. The first anode is coupled to a source of voltage at a first potential. The first cathode is coupled to a source of voltage at a second potential. The anode and cathode are selectively adjustably positionable within the water to bring the anode and cathode sufficiently near for arcing to occur between the anode and cathode. The anode and cathode comprises a series of carbon rods electrically coupled together. The reaction chamber includes a photon transmissive sidewall and transparent sidewall (10). In the energy conversion apparatus, a duct (24) conveys hydrogen in the collector to an intake manifold of an internal combustion engine; and a Stirling engine receives heated water from the reaction chamber. An INDEPENDENT CLAIM is included for an engine comprising a reaction chamber containing a supply of water, at least a first anode, at least a first cathode, and solar collectors.
