Garrett carburator - Browns Gas
The late Henry "Dad" Garrett was a multi-talented Dallas inventor with a bent for electrical contrivances, and in 1935, he and his son, C.H. Garrett, patented and exhibited an automobile that ran on water -- actually, on hydrogen after the water was broken down by electrolysis.
Dad Garrett was already famous for his work. In 1920 he set up WRR in Dallas, the world's first municipal radio station, and was its first announcer. He was the first man to build a radio in his car, and he developed radio transmission from the car for police use. He also invented an automatic electric traffic signal, possibly the nation's first.
Eugene P. Aldredge recalled the Garretts: "I had rented a small office on the seventh floor of the Allen building in downtown Dallas for my letter service, and one of my early customers was the eighteenth floor National Electric Signal Co. owned by Dad Garrett and son C.H..
"I was informed that the two were experimenting with an automobile that used water for fuel, that they carried on their experiments in a workshop adjacent to their office on the top floor, and that two separate explosions (from dangerous hydrogen) had nearly blown a hole in the roof of the building...Neither was hurt."
On September 8, 1935, The Dallas Morning News first announced that the water-fuel concept worked -- at least it worked for "several minutes," the article reported.
