TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The content of stabilizing additive is 1.5-15 volume%. The ratio of hydrogen peroxide and hydrocarbon is 31.3:6.9-46.9:6.3. The hydrocarbon is a hydrocarbon mixture. The hydrocarbon amount is chosen such that the stoichiometric amount of oxygen provided by hydrogen peroxide is approximately equal to the stoichiometric amount of carbon provided by the hydrocarbon. The fuel comprises (in volume%) additive chosen from anti-knock additive (2-5.7), anti-oxidant additive (10-15), static dissipater additive (0.6-4.5), icing inhibitor additive (0.1-0.15), corrosion inhibitor additive (0.05-0.2) and/or power boosting additive (0.02-2). The hydrocarbon mixture contains aromatic hydrocarbon (10-20 wt.%), olefinic or alkene hydrocarbon (0.5-1.5 wt.%), and saturated paraffinic hydrocarbons (80-85 wt.%), such as alkane and/or cycloalkane. The aromatic hydrocarbon is benzene derivative, such as toluene, xylene and/or ethyl benzene. The olefinic hydrocarbon is 3-15C hydrocarbons with 1-3 double bonds. The aliphatic hydrocarbon is linear or branched 4-15C hydrocarbon. Preferred Additives: The stabilizer additive is room temperature liquid alcohol, such as ethanol and/or propanol, or a surface-active agent having a hydrophobic and a hydrophilic group, preferably tenside. The anti-knock additive is propylene alcohol, ketone and/or aldehyde. The antioxidant additive is phenol, organic sulfide or polysulfide, dithiocarbamate, phosphate and/or phosphonate. The static dissipater additive is nitroso compound. The icing inhibitor is isopropanol and/or isopropylene. The corrosion inhibitor is phenol derivative, such as dibutylmethylphenol and/or butylhydroxyanisol. The power boosting additive is nitrated aromatic compound, such as trinitrobenzene. Preferred Method: The colloidal fuel composition undergoes chemical transformation process, in which atoms are re-arranged to produce water and carbon dioxide as output. The transformation provides reduction of the Gibbs free energy. The stabilizing additive participates in the chemical reaction. Preferred Apparatus: The vaporizing unit transforms the colloidal fuel composition into a fuel vapor or fuel cloud having particles, droplets or entities having size of less than 100 mu m, preferably less than 50 mu m. The vaporizing unit has expansion factor of 5-50, preferably 10-30. The activation unit has heating element or heating section designed to raise the temperature of the fuel to more than 50 degrees C, preferably 100-150 degrees C. The activation unit further has a catalyzer. The reaction unit has a reaction zone or chamber and an ignition system for triggering a reaction which transforms the fuel into the water and carbon dioxide. The reaction unit is maintained at pressure of more than 50 bar, preferably 60-80 bar.
