  • Environmentally friendly methods and systems of energy production
    Patent number: 8383870
    Abstract: A process of energy production is disclosed. The process includes integrating three or more energy production technologies such that a first byproduct of a first energy production technology is applied to a second energy production technology and a second byproduct of the second energy production technology is applied to a third energy production technology. The process also includes operating the integrated energy production technologies to produce energy such that at least a portion of the first byproduct is utilized in an operation of the second energy production technology and a portion of the second byproduct is utilized in an operation of the third energy production technology.
    Type: Grant

  • Method and apparatus for monitoring physical integrity of a wall in a vessel
    Patent number: 6194890
    Abstract: An apparatus and method is described for monitoring the physical integrity of a vessel, such as a molten metal reactor. The apparatus includes a vessel for containing an electrically-conductive liquid having at least one electrically-grounded detection unit located within the containment wall of the vessel. Monitoring changes in electrical current flow of the detection unit relates to the physical integrity of the vessel containment wall and prevents unanticipated breaching of the vessel by the electrically-conductive liquid.
