    "title": "MIST Impact Steam Generator",
    "inventor_name": "Richard AHO",
    "publication_year": 2013,
    "device_name": "Impact Steam Generator",
    "goal": "Produce super-heated steam with far lower external energy input than conventional boilers.",
    "problem_addressed": "High energy and cost requirements for generating steam, especially super-heated steam, in power-generation and industrial processes.",
    "concept_summary": "Water is injected at ultra-high pressure (10 000-30 000 psi) through piezo-type injectors. The resulting hypersonic water-jet (1 700-3 000 m/s) strikes a hard surface inside an impact chamber, causing an instantaneous phase transition from liquid to vapor (steam) without traditional boiling. The kinetic energy of the water clusters is claimed to be amplified on impact, releasing additional energy from hydrogen-bond disassociation, yielding output steam power that exceeds the electrical input.",
    "detailed_description": "The system consists of a water source, a high-pressure injector (often a modified Ford diesel piezo injector with multiple orifices), an atomizer, an impact chamber with a hard contact surface, and an expansion chamber. Water pulses of 0.1-0.5 ml are injected at 10 000-29 000 psi, achieving velocities of 1 710-3 415 m/s. Upon impact, the water undergoes a virtually instantaneous phase change to steam, which is then expanded and can be used for cleaning, turbine drive, or other steam applications. Test data in the article claim conversion of 2 lb of water per minute into super-heated steam using a 10 HP motor (~=7.5 kWh) and delivering 1 139 W of steam power from only 124 W of electrical input, giving a cost of $0.00683 per pound of water. The inventor attributes the excess energy to the \"bonding energy of water molecules\" released during the ultra-fast impact (the so-called water-arc explosion or cluster electric effect).",
