Abstract:
A release of the frozen solvent trapped inside a solidified gel occurs when the temperature increases, followed by a dissolving of a reactive substance present in a membrane that is located in direct physical contact with the gel, resulting in the reabsorption of the reactive substance dissolved in the solvent into the solid gel layer within a constant time. In this manner, the components generating color change come together within the solid gel layer initiating a reaction to change the color of the indicator layer. Thus, the increase in temperature above a melting point of the solid gel layer is enough to activate the intelligent label with an irreversible color change.

Abstract:
Systems and methods for storing energy in gaseous form in submerged thin-wailed tanks (1, 7, 61, 82, 63, 67, 101) are secured to the ocean or lake floor but are open to the water at the tank bottoms (1a, 64) and are configured to be filled with gas while submerged. A conduit (2, 2a, 11) operatively connected to the tanks (1, 7, 61, 62, 63, 67, 101) provides flow from a surface source of an energy-containing gas to the tank interiors (1d, 101 a). Surface or subsurface pumping apparatus (3, 37, 42, 46, 48, 53) which may include piston-less pressure cylinders (37) or have leveraged pistons (48, 53) provide a preselected flow rate of the energy-containing gas into the tank interiors (1d, 101 a) against a back pressure essentially equal to the static pressure of the body of water at the location of the tank (1, 7, 61, 62, 63, 67, 101) to displace an equivalent volume of water through the open bottom (1 a, 64). The conduit (2, 2a, 11) can be configured to allow heat transfer to vaporize liquefied gas prior to storage. Hydrogen gas can be generated and stored within the tank (1, 7, 61, 62, 63, 67, 101) using Aluminum activated with Galinstan.
