  • Patent number: 10781099
    Abstract: An underwater hydrogen generator can include a watertight reaction housing enclosing a metering chamber. The metering chamber can have an upper portion that terminates at a piston opening, and a lower portion that merges into a funnel, which can further terminate at a metering opening. The metering chamber can be filled with an acid accelerator, and the watertight reaction void can be partially filled with NaBH4 in solution. The generator can further include a seawater float valve that can be in fluid communication between the external environment, the metering chamber and the void defined by the reaction housing. The float valve, metering chamber and reaction housing can cooperate to generate hydrogen when said generator is submerged, by allowing seawater to contact both the acid accelerator and the NaBH4. The size of the metering opening can determine the rate at which acid accelerator is added to the NaBH4 solution.

  • Publication number: 20180120690
    Abstract: A photoactive solution system for at least one of photochromic liquids and photoconductive liquids, involving a protonating solvent, comprising at least one of a first solvent and a second solvent, and an anthracene-derivative solute configured to dissolve in the protonating solvent, whereby a photoactive solution is responsive to light having a wavelength in at least one of a visible spectrum, a near-ultraviolet spectrum, and an ultraviolet spectrum, and whereby a photoactive response is elicitable.

  • Publication number: 20170369142
    Abstract: A system for supplying hydrogen gas to a lighter-than-air (LTA) vehicle includes a manifold having multiple vessels. Each vessel has a first chamber that is separated from a second chamber by a barrier. A trigger assembly integrated with the barrier allows a liquid to be combined with a reactant and a catalyst in the second chamber to form a chemical reaction to generate hydrogen gas. A pressure relief valve located on each vessel opens to allow the hydrogen gas to exit when a predetermined pressure is reached, and the hydrogen gas is supplied to the LTA vehicle connected to the manifold.

  • Patent number: 8771634
    Abstract: The present subject matter provides heat management while generating hydrogen gas from a hydride achieved by coupling a hydride with a hydrate. The present subject matter unexpectedly provides improved methods so that the heat released by the hydride during hydrolysis is accurately balanced by the heat absorbed by the hydrate as the hydrate undergoes a phase transition to a less hydrated or to an anhydrous form. Examples of heat-moderated hydrogen generating systems are provided, and include, among others: NaBH4/Na2SO4.10H2O, NaBH4/CoSO4.7H2O, and NaBH4/FeSO4.7H2O. The subject matter provides a methodology for determining the correct proportions of hydride/hydrate to use in preparing a hydrogen generator capable of operating at a nearly constant temperature at or near a phase transition temperature of the hydrate or at a higher temperature that is still within a desired temperature range, such as, for example, 30-90° C.

  • Patent number: 8250850
    Abstract: A pollution-free propulsion engine includes a rotating arm, a hollow axle defining a fuel delivery chamber, and hydrogen and oxygen sources. The rotating arm is formed with a detonation chamber, an opening and two tubular ducts therebetween. The axle is inserted into the opening. A pair of holes is formed in the axle to establish paths of fluid communication from the fuel delivery chamber through the ducts and into the detonation chamber as the rotating arm turns. The hydrogen source comprises a thin palladium binding layer deposited onto an aluminum sheet. Hydrogen molecules that are trapped in the binding layer are released, and the hydrogen is fed into the delivery chamber, through one duct and into the detonation chamber. At the same time, oxygen is delivered into the detonation chamber through the other duct, and the oxygen-hydrogen combination is detonated to release energy, which is converted into mechanical energy.

  • Patent number: 8240602
    Abstract: A lighter than air (LTA) balloon and payload for the LTA balloon are stored on or in an underwater launcher. The launcher provides a source for a supply of a lighter than air gas, which is operatively connected to the LTA balloon until release. On deployment, the lighter than air gas is generated. The LTA balloon is deployed by activating the launcher to fill the LTA balloon and then releases the LTA balloon.

  • Patent number: 7655115
    Abstract: An apparatus and method provide a solute-solvent solution that allows the solute to become photo-protonated by the solvent on absorption of ultraviolet light. The solute is 1,2,3,4,5,6,7,8-octamethylanthracene (OMA). The solvent is 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP). The protonated form of the solute absorbs visible light to change the coloration of the solution from a substantially clear state to a colored state.

  • Patent number: 6776971
    Abstract: A method and apparatus for initiating a rapid and long-lasting pH change to a pH dependent polymer or other pH driven reactant is provided by a pH jump molecule in solution. Visible light is used to excite the pH jump molecule. The attendant pH change occurs rapidly (in nanoseconds) and can be maintained by continuous wave light or by an appropriately pulsed light. Heat resulting from the light activation is efficiently discharged by radiative decay through room temperature phosphorescence lifetimes existing on the order of milliseconds.
