NOVELTY - Economically converting agricultural by-product cellulose/lignite to methanol involves gasification of the by-product agricultural material to carbon dioxide; and reaction of the carbon dioxide with hydrogen gas obtained by the electrolysis of water, to form methanol with water as byproduct.    USE - For economically converting agricultural by-product cellulose/lignite to methanol used as alcohol fuel (claimed) in automobile engines and automobile servicing and repair industry and in automotive industry; and as motor fuel.    ADVANTAGE - The quantity of alcohol fuel produced by agricultural region is increased without increase in the area under cultivation. The method of co-producing methanol with ethanol fuel produces a manifold increase in the alcohol fuel produced from an agricultural region without increase in the area or tonnage of the crop under cultivation, typically to provide a six-fold to seven-fold increase in the quantity of alcohol fuel. The methanol used as alcohol fuel is cheap to manufacture; is suitable for use in existing four stroke piston engines of the spark ignition type (petrol) or the compression heat ignition type (diesel); can be dispensed in the normal way using existing equipment and primary and secondary fuel distribution infrastructures; is safe as or safer than petroleum and dieseline both as concerns primary and secondary distribution and in traffic accidents; exhibits drivability characteristics that are equal to or superior to the existing fuels, petroleum and dieseline such as acceleration, top speed, torque, idling, cold start and hot start; is as efficient or more efficient in terms of distance traveled per unit cost; exhibits pollution characteristics that are equal to or better than those evinced by petroleum and dieseline; is able to be introduced gradually into the existing worldwide transportation network and infrastructure, incorporating such diverse elements as technical college training, motor vehicle design, legal statutes, vending, road safety, bulk transportation capability and many others. The methanol exhibits superior fuel efficiency, cost and pollution characteristics. The alcohol fuel has lower pollution profile than traditional fuel petrol and diesel. The method secures a delivered electricity cost at a minimum level and minimizes the capital cost associated with the synthesis facilities themselves, together with raw material and finished product storage volumes. The use of wind power as the primary energy source for the production of hydrogen gas by electrolysis renders the entire process of methanol fuel production sustainable without recourse to the exploitation of fossil fuel or nuclear energy. The use of wind turbines to provide electricity for alcohol production stations, located on grid system throughout the corn belt minimizes reticulation problems.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) economically converting the carbon dioxide that is universally exhausted by the process of fermentation, and in particular the fermentation process to produce ethanol fuel, to methanol involving the process of reacting the exhausted carbon dioxide against hydrogen gas, where hydrogen gas is produced by the electrolysis of water; and    (2) producing hydrogen gas involving using electricity generated by external sources, and in particular wind turbines, in conjunction with electricity produced from power stations employing waste agricultural produce as the calorific fuel.
