    "problem_addressed": "Dependence on petroleum fuels, difficulty storing pure hydrogen, safety hazards of conventional oxy-hydrogen mixtures.",
    "concept_summary": "Water is subjected to low-frequency mechanical vibrations that break surface tension, producing nanobubble-laden water. Electrolysis of this \"broken-surface-tension\" water yields a stable H_2-O_2 nanobubble gas (OHMASA-GAS) containing hydrogen, oxygen, atomic hydrogen and traces of deuterium. The gas does not explode under pressure, liquefies at -178  deg C, burns at ~700  deg C and can vaporize tungsten. It is claimed to run engines and torches cleanly, emitting only water vapor.",
