A system and method of making hydrogen from water. A cylindrical reaction vessel is provided with an outer shell, a central shaft, and one or more concentric inner tubes separated by annular spaces. Water is delivered to the annular spaces by a water pump through an inlet defined in the reaction vessel. The water courses along a tortuous flow path. That path begins at an inner annular space around a central shaft. It ends at an outer annular space. The water emerges from the reaction vessel through an outlet associated with a manifold. A high-frequency vibratory stimulus is applied to the reaction vessel and water. Water molecules are dissociated into hydrogen molecules and oxygen atoms. These reaction products are delivered through the manifold along an effluent flow path to a receiving pressure vessel before deployment to a sub-assembly for harnessing clean energy.

Resumen de: US20260035242A1
A hydrogen generation system with controlled water distribution is disclosed. The system comprises a reaction chamber containing a hydrogen-producing fuel, a liquid distribution mechanism, and a control system. The liquid distribution mechanism includes a rotating arm with liquid injection ports that move vertically through the fuel chamber. This allows for precise and efficient liquid delivery to unreacted fuel, optimizing hydrogen production. A proprietary fuel blend utilizes chemicals that store significant amounts of hydrogen in a solid-state form. A feature of the device is the arm's controlled vertical movement, achieved through a screw mechanism that adjusts the arm's height as it rotates, creating a spiral liquid distribution pattern. The control system regulates liquid injection rates, arm rotation speed, and vertical movement to optimize hydrogen production based on demand. The system can also operate at low pressures and be scaled to different sizes in a safer, more efficient, on-demand manner.
