    "device_name": "Synthetic Fuel Process",
    "goal": "Produce a renewable, low-emission synthetic fuel from inexpensive feedstocks with an energy return that exceeds the energy input.",
    "problem_addressed": "Dependence on petroleum fuels, high emissions (CO, NOx, unburned hydrocarbons) from conventional fuels, phase-separation issues in ethanol-gasoline blends, and high energy cost of fuel production.",
    "concept_summary": "The invention uses electroplating currents to polymerise a mixture of water, vegetable oil, methanol and activator chemicals into macromolecular colloids, followed by two distillations, to create an alcohol-type fuel. A related embodiment combines methanol, butanol, naptha (or other heavy hydrocarbons) with magnesium laurel salts as a colloidal stabiliser, producing a range of fuels (gasoline extender, diesel, heating oil, aviation fuel) with high oxygen content and reduced emissions.",
    "detailed_description": "In the first approach, 80-90 % water is mixed with soybean oil, methanol and a small amount of activator chemicals; electroplating current induces the formation of macromolecules/colloids, after which the mixture is distilled twice to yield a fuel with an energy content of ~85 000 BTU / gallon. The process reportedly returns 3 BTU of fuel energy for each BTU of electricity consumed. In the second approach (US 4300912), methanol, butanol and a heavy hydrocarbon (naptha, kerosene-type oil, vegetable oil, etc.) are combined with magnesium laurel salts, heated to ~300  deg F, and condensed to produce a stable synthetic fuel that can be blended with gasoline or used alone. The fuel's high oxygen content lowers the stoichiometric air-to-fuel ratio, reducing NOx, CO and unburned hydrocarbons, and the colloidal stabiliser prevents phase separation.",
