The hydrogen Nascar circuit may yet be a few years off, but in a warehouse in Philadelphia Sunday, the simple chemical reaction of H2 + O2 kicked the crap out of the competition in this year's Chem-e-Car race. The event tasks teams of college students to build RC-size cars that can carry one cup of water 60 feet, fueled only by a chemical reaction. It's sponsored, appropriately, by the American Institute of Chemical Engineers.
The winning team, from Cornell, used a fuel cell to generate DC current that powered a Lego motor. Other fuels this year included candy sours (citric acid), beetle liver (catalase enzyme), and fire starters (magnesium). The race's twist is that the car must also stop using a chemical reaction, and the closer to the finish line it stops, the better. The Cornell team is the first in history whose vehicle stopped directly on the finish line with a braking system made from an Iodine solution and a light sensor. When the solution turns dark, the light sensor triggers a circuit switch so that the power that had been driving the motor instead lights an LED.
Second place went to Louisiana State University for the above-mentioned citric acid engine, and the Texas A&M took third with a combo of sodium carbonate and hydrochloric acid.
whatever matter of fact could you do a train with multiple turbo reactor, reacted hydrogene propulsor,with no toxic emissions fumes,mercure or else,it will be high speed phenomenal power,the double rocket hydrogene of the space shuttle prove it,could be a.. way of locomotion for the future..ecologic dream.with low level of vapor fume.
