Abstract:
This invention mitigates global warming substantially by combining elements from two separate fields in a novel way. It is based on the discovery that the volumetric rate of cold water upwelling that will result in a 1.08 C reduction in the Earth's Surface Air Temperature (SAT) is similar to the volumetric rate of cold water upwelling that would be produced by roughly 20,000 OTEC plant-ships of 400 MW size each. These can generate 7 terawatts of electric power converted to an ammonia energy carrier and shipped to on-land locations, where it can be "cracked" and burned as C02-free fuel for power plants. The large reduction in SAT enables proposal of an affordable financial strategy that would pay most of the costs of the system out of the revenue from C02 emission allowances granted by governing agencies for alternative energy systems that also cause a direct reduction in SAT.

Abstract:
A cold water piping system including a floating platform (50) having horizontal and vertical surfaces, the platform including a moon pool generally in the middle of the horizontal surface in the form of a vertical cylinder with four recesses (62) having a rectangular shape, an articulating interface (51) suspended directly from the platform, the interface including a tubular shape made of fabric and a bellows assembly disposed at a bottom portion thereof. The system also includes at least two suspension cable assemblies secured to the platform, where the at least two suspension cables cross the moon pool (58), vertically mounted modular elements (53), where ends of the suspension cable assemblies are fastened to a top modular element at four diametrically opposed points, and a strainer (54) having sea water intakes including a counterweight (64) connected to the lowest modular element. The system also includes winches (56) disposed on the horizontal surface of the platform and deployment cables (57) connected to the strainer and winches.
Abstract:
The invention relates to energy conversion and generation systems, and more specifically, to a system and method of generating and converting energy by way of a pressure differential in a working fluid. A Pressure Power System is described comprising a cold sub-system, a warm sub-system, a work extraction system, and a hydraulic pump arranged in a closed loop. The cold sub-system and the warm sub-system are respectively maintained at lower and higher temperatures relative to one another, so that a Working Fluid circulated through the closed loop by the pump, will have different equilibrium vapor pressures in the two sub-systems. The different respective state functions of the Working Fluid results in two different levels of elastic potential energy, and subsequently, a pressure differential between the two sub-systems. A work extraction system is positioned between the two sub-systems to convert the elastic potential energy/pressure differential into useful kinetic energy.
Abstract:
A process is described that employs what can be termed a friction surface stirring (FSS) process on the surface of a metal object. The FSS process occurs on some or the entire surface of the metal object, at a location(s) separate from a friction stir welded joint. The FSS process on the surface produces a corrosion resistant mechanical conversion "coating" on the object. The "coating" is formed by the thickness of the material of the object that has been FSS processed. In one exemplary application, the process can be applied to a metal strip that is later formed into a tube whereby the "coated" surface resides on the inside of the tube making it highly resistant to corrosive flow such as seawater.

Abstract:
Wave powered pumps have proven themselves to be a cost effective means of delivering a liquid to a hydroelectric plant on shore, the use of brine or a dense liquid (denser than sea water) as a gravity fuel can make use of a wave pump as the brine can be made to work in a closed cycle using the wave energy to change its potential energy offering the same advantages as an onshore hydroelectric plant which uses wave power but with much greater height potential.
