  • Publication number: 20230056889
    Abstract: High energy consumption and the negative impacts of hyper saline brine are the two biggest hurdles to a widespread adoption of seawater desalination. Taking advantage of the principal that fluid pressure increases in direct proportion to depth, this invention reduces energy consumption by relocating the process of reverse osmosis at depths where the weight of the water produces the pressure required to drive the reverse osmosis process thereby eliminating the high costs normally associated with raising intake pressure and by simply varying pumping rates, the brine stream can be pre-diluted to levels slightly above the original thereby reducing environmental impact. The simplicity of the design also reduces the costs of building and installation thereby making it likely that seawater desalination will proliferate around the world.

  • Patent number: 9022006
    Abstract: Many IC engine inefficiencies are linked to the relatively low mixture formation rates of current injection methods. Process intensification (PI) is excellent at high mixture formation rates, high mass transfer rates, and short residence times, therefore a wall integrated injection method and device featuring PI has been provided. It allows increased number of injection sites and interfacial surface area between fluid jets and the volume of the squash area, hence high mixture formation rates shorter Liquid Lengths and the use of micro nozzles to further intensify the mixing process by locally mixing fuel and oxidant. This allows high EGR and low compression ratios and better control of HCCI start of ignition. PI effectively achieves thermo and species stratification for extending the load range of the HCCI engine while permitting effective water addition for reciprocating and turbine for lower exhaust heat and less fuel burned hence less CO2 emissions.

  • Publication number: 20090223217
    Abstract: A method and apparatus for pressurizing a fluid within a combustion chamber and storing that pressurized fluid in a reservoir for later use to power a motor or do other work. The invention includes the apparatus to achieve the method. The method comprises the steps of determining and selecting the particular material or compound to be used as a fuel; one the type of fuel is selected the method involves selecting the reagents necessary to create the fuel; storing the reagents and raw materials; reacting the reagents and raw materials together; conditioning the output from the reacting process; purifying, separating and reusing the reagents from the finished fuel produced by the reacting process; conditioning the material; delivering the material or compound to the combustion chamber; combusting the fuel to produce a high pressure gas; recycling waste of the combustion; and storing the high pressure gas in a vessel.
