I was doing a little research on the town I will be staying in during Camp Jeep.
Believe it or not, this car runs on Kool-Aid. Over twenty years ago, during the energy crisis in the late 1970's, local inventor Roy Calloway devised a carburetor that overcame evaporation problems with sugar-based fuels in gasoline engines. Needing a soluble mixture for the sugar, his experimentation led him to the popular children's drink, Kool-Aid, which he discovered to have just the right properties. Eventually, Calloway perfected the fuel mix (80% Kool-Aid and 20% methanol or ethanol) which, together with his special carburetor, provided an alternative to gasoline in gasoline-based engines. Calloway's attempt to secure a patent, however, was blocked by the major oil companies, who enlisted the help of the powerful Washington Crude Oil Lobby in eventually getting laws passed that have kept Calloway's invention from seeing the light of day...almost that is. Calloway, in defiance of a little-known federal law that forbids the operation of any motor vehicle that burns a sugar-based fuel, can frequently be seen cruising around Lynchburg in his lime-green "Kool-Aid Kar." Risking arrest each time he hits the road, Calloway has decked his car out with signs and decals that bring attention to the unfair treatment he has received at the hands of the big oil companies and the Federal Government. In fact, from various convictions through the years, Calloway has spent a total of seven years in jail; but he refuses to be silenced. According to Calloway, grape-flavored Kool-Aid provides the best mixture and results in the best mileage - 89 miles to the gallon.
