Abstract

Plusieurs susbtances chimiques constituant un combustible aqueux sont liés de manière organique entre elles et ne se décompose pas facilement. Selon l'invention, les liaisons sont cassées de force et les substances chimiques sont extraites individuellement ou brûlées. De l'eau sous pression est amenée dans un espace sous vide à une température élevée, puis elle est vaporisée et ensuite chauffée pour la transformer en vapeur d'eau surchauffée. Ainsi, le liaison entre l'hydrogène et l'oxygène est rendue instable, une quantité affine d'un combustible fossile nécessaire pour provoquer la réaction d'oxydation par l'oxygène est amené sous pression dans l'espace afin de décomposer sensiblement l'eau en hydrogène et en oxygène et permettre à l'hydrogène et au combustible fossile de brûler, ou d'extraire séparément l'hydrogène et l'oxygène.
