Abstract: A method and apparatus for obtaining carbon fiber from carbon fiber waste (e.g., pre-preg and CFP waste). The method and apparatus selects, or is controlled to select, between using an oxygen free pyrolytic process to volatilize the epoxy resin or other matrix in which the fibers are held to liberate the fibers therefrom and, depending upon the type of pre-preg waste, using a reactor environment where the reactor atmosphere has about 1% to about 2% oxygen by volume. The reactor has a counterflow such that the carbon fibers are moved in one direction and the off gasses are moved in the opposite direction. A combination of steam at the reactor outlet and vacuum pressure at the reactor inlet create the counter flow.

Abstract: A water purifying and desalination system includes solar concentrators that receive a sunlight and direct the sunlight toward a collection element. The collection element absorbs and converts a solar radiation into thermal energy. A superheater tube enclosed by the heat collection element controls volume flow that partially fills the superheater tube with processed ocean water, which allows steam to escape into a portion of the superheater tube that generates electricity and additional processed ocean water.

Abstract: The sub-ambient solar desalination system includes a solar pond and a pressure reducing structure. The solar pond is adapted for receiving saltwater and heating the saltwater through direct exposure to solar radiation at atmospheric pressure. The pressure reducing structure is in fluid communication with the solar pond for receiving heated saltwater therefrom. The pressure reducing structure is configured such that pressure of the heated saltwater within a central portion of the pressure reducing structure is at sufficiently reduced sub-ambient pressure to undergo a phase change to produce pure water vapor and a concentrated brine solution. The pressure reducing structure has a vapor outlet for releasing the pure water vapor, which is collected in a fresh water tank and condensed into pure liquid water. The solar pond is in fluid communication with an outlet portion of the pressure reducing structure for recycling the concentrated brine solution back to the solar pond.

Abstract: The invention relates to chemical-based methods and products for mitigating the impact of an oil spill, that act via mechanisms which include reducing adhesiveness, herding, thickening and gelling. N-fatty acid amino acid (FA-AA) conjugates display oil-herding behavior when formulated as a salt, or the free acid in water-miscible organic solvents. Various salts of FA-AA conjugates are water soluble and can herd oils and increase the thickness of the oil layer. Replacement of the acid group of fatty acid ?-amino acid conjugates with other groups that act as hydrogen bond donors and acceptors results in potent phase selective organo gellants. The oil thickeners or gellants include can be prepared from biobased feedstocks, have low toxicity, high capacity for oil and reduction of the need to use an organic solvent to apply the thickener or gellant to an oil and water mixture in order to gel the oil phase.
