  • Patent number: 7328584
    Abstract: A method and apparatus for collecting fresh water through atmospheric water collection and salt water desalination. The apparatus is used for a method of utilizing deep ocean water to extract fresh water from atmospheric water vapor while producing a byproduct of deep ocean water salt. The apparatus and method may include multiple vertical stages that utilize siphons and heat exchangers to move vapor condensing means through a plurality of stages to produce fresh water at every stage.

  • Patent number: 7069689
    Abstract: A system and method for regulating plant growth according to the creation of temperature gradients within the vegetative portion of a plant and its roots or rhizomes. A system of pipes or conduits capable of thermally manipulating their surrounding environment is placed within proximity of roots or rhizomes to create a temperature differential across the selected plant species. Through temperature variations created by thermally conductive pipes or conduits, plant growth can be regulated.

  • Patent number: 5744008
    Abstract: A simple, portable and efficient water desalination device uses deep ocean water, solar energy and the dynamics of generated secondary vortices. The device includes a tower, a heat exchanger positioned inside the tower near the top of the tower, a cold water source, a cold water receiving tank, a condensate catchment grille, a freshwater collecting tank, a rotor extending upward between the side walls of the tower from a lower portion of the tower, a power source for driving the rotor, a warm salt water pan positioned in the bottom of the tower and a warm salt water source. The cold water source is cold deep ocean water that is siphoned to the top of the tower through rollable, transportable fabric pipes. The warm salt water source is solar heated ocean water. In the tower, a hurricane is simulated by a rotating column that induces a circulation of air which approximates that of a hurricane.
