NOVELTY - Gas enrichment for a bio-fuel comprises: hydrogen enrichment of a fuel emulsions water-insoluble part as an aerosol product (1), including providing concentrated alcohol surfactant kerosine and vegetable oil in partial solution within a liquid petroleum gas (LPG) aerosol propellant as produced by electrolysis of a gas store or catalytic fuel reforming; and oxygen enrichment of a fuel emulsions water-soluble part as (1) including providing water dilute alcohol and surfactant with an oxygen gas propellant produced by electrolysis or a gas store, with mixing, and a means of production.    USE - The process deals with the gas enrichment technique for the bio-fuel.    ADVANTAGE - The method is a safe, clean and versatile method for enriching the bio-fuel.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following:    (1) a means of producing stable gas propellant-enriched fuel and oxidant emulsion products comprising a surfactant to create the emulsions on mixing with agitation and a starch derived gel to set the emulsions on gentle cooling and then chilling to below 0degreesC;    (2) a bio-fuel, where the mixed fuel emulsion comprises fuel oil, a surfactant and pure alcohol as product with LPG and pressurized hydrogen propellant producing an aerosol vapor with constant composition forming a ternary azeotrope;    (3) a pre-mixed oxidant emulsion comprising water, a surfactant, ethanol solution, methanol solution, fuel oil and pressurized oxygen in binary or ternary azeotrope constant composition vapor product form;    (4) a combined heat and power (CHP) application comprising a means of improved thermodynamic coupling of the expander turbine with the engines waste exhaust heat, a means of removing the moist exhaust and particulates from the exhaust and a means of cooling the expanders condenser walls by centrifugal filter action;    (5) an exhaust heat-driven CHP application, where the expander turbines are mechanically-coupled to electricity generators;    (6) a CHP-driven electrolysis, where the generators provide electrical power which can be switched between the fuel-oxidant electrolysis and the drive wheels via a hybrid drive system;    (7) an in-pipeline electrolysis, where the fuel line is divided into two extended differentially pressurized pipeline sections of different volumes via one-way flow valves the inner hollow surfaces of which are coated with any relatively electronegative conductive material to include copper as electrodes;    (8) an in-store electrolysis, where the dual fuel and oxidant in differentially-pressurized stores have insulated inner walls with charged conductive central pipeline electrodes collecting fuel and oxidant from the lower part of the pressurized liquid fuel stores comprising mixed oxidant tri-state and bi-state products;    (9) a fuel store or an oxidant store comprising a bio-fuel colloid or an oxidant colloid which is provided in de-pressurized form for periodic dispensing or exchange with additional compressed gas cylinders providing an alternative means of pressurized fuel enrichment or oxidant enrichment to electrolysis;    (10) a method of mixing a pre-mixed emulsion in store including a rotating stirrer armature suspended in-store and excited by a rotating magnetic field applied externally through the store walls by a static stator; and    (11) a means of gas enriched bio-fuel production comprising: alcohol from a multi-stage pressurized biomass continuous fermentation tower producing 10 v/v.% dilute alcohol in wort, a wort filter and settling tank, a solar-powered still to produce 95 v/v.% of concentrated alcohol from the wort, a refrigeration plant to produce LPG and methane combined production from pressurized producer gas carbon sequestration and natural petroleum gas well or piped gas by propane, butane and carbon dioxide liquefaction at 0, -42 and -44degreesC boiling point respectively, hydrogen gas production from wort electrolysis, oxygen gas production from wort electrolysis, a sworl mixing chamber for producing fuel emulsions with dehydrated concentrated alcohol 100 v/v.%, a further swirl chamber for mixing the fuel emulsion with a gel with a stirrer and chiller, stores containing kerosene, straight vegetable oil, filtered wort, the gel, enricher gasses and surfactants.
