Conventional steam generation engines are inefficient in terms of energy use when converting liquid water to steam.
Innovation Solution
A cavitation engine is designed with an impact chamber and fluid injector to create cavitation bubbles in liquid water, which are then crushed at supersonic velocities onto a heated impact surface, generating high-pressure superheated steam by optimizing the angle, distance, and temperature of the impact, resulting in improved energy efficiency.

1Use of energy by moving object
If liquid water is injected onto a heated impact surface to generate steam, then steam production is achieved, but energy efficiency is poor
Solution Approach 1:
Cavitation bubbles are generated in the liquid water before impact with the heated surface. This preliminary cavitation action creates pre-formed vapor bubbles that dramatically reduce the energy required for phase transition, as the bubbles collapse and expand rapidly upon impact, efficiently converting thermal energy to mechanical work and steam generation.
Solution Approach 2:
The invention utilizes phase transition from liquid to vapor through cavitation bubble formation and collapse. The cavitation process creates vapor bubbles that rapidly collapse upon impact with the heated surface, generating localized high temperature and pressure zones that efficiently produce superheated steam, thereby improving energy conversion efficiency.
2Productivity
If water is injected at high velocity to create cavitation bubbles, then steam generation efficiency improves, but precise control of injection parameters is required
Solution Approach 1:
The system dynamically adjusts injection parameters including water pressure (hyperbaric conditions), injection velocity (supersonic range), and injection angle (85-95 degrees) to optimize cavitation bubble formation. The dynamic control ensures that cavitation bubbles are generated at the optimal moment and position for maximum energy transfer and steam generation efficiency.
Solution Approach 2:
The invention optimizes specific parameters: injection distance from impact surface (3.81-11.43 mm), injection angle (85-95 degrees), and water pressure (hyperbaric). These parameter changes are carefully controlled to ensure proper cavitation bubble formation and collapse, maximizing steam generation while maintaining system reliability.

AI summary
A cavitation engine configured to produce superheat steam from injected liquid water. The cavitation engine includes a funnel shaped impact chamber having an impact surface having a temperature of at least 375 degrees Fahrenheit, a small diameter opening at a bottom of the impact chamber, and an expansion chamber below the small diameter opening. The engine includes a fluid injector having an outlet positioned adjacent a largest diameter of the impact chamber and located to inject hyperbaric liquid water onto the impact surface of the impact chamber at supersonic velocities such that cavitation bubbles are present in the injected water. The outlet of the fluid injector and the impact surface are located relative to one another such that the outlet is spaced a distance from the impact surface of between 0.150 and 0.450 inches and the injected water hits the impact surface at an angle of between 85 and 95 degrees.
