A NEW HYBRID ENGINE

Next week at the Inventors Showcase in San Diego, Santana High School seniorJosh Smith plans to unveil an invention he hopes will hold an answer to the energyriddle.

Constructed from an old lawn-mower engine, the hybrid engine runs on fourdifferent types of fuel: gasoline, propane, methanol and hydrogen.

I built this engine to simply prove that its not difficult to run any engine onmany different fuels, the inventor said.

The machine is simplistic in appearance but performs a unique function alterating between four very different fuel sources with the flip of a switch, all while

the motor is running.Gas is used first because methanol, an alcoholic substance similar to ethanol, lacks the

punch needed to heat the engine for full ignition. Smith will demonstrate that process to the judgesat the Inventors Showcase.

The project started more than a year ago as part of an effort by Santana High School to findmethods of producing hydrogen fuel.

Jacob Bagnell, an automotive teacher who also taught Smiths father and older brother, donated thelawn-mower motor for the machine.

He assisted Smith in bringing his idea to life and said the young inventor worked hard toapply complicated scientific principles to his project.

Smith, 17, got the idea for the hydrogen energy while he was in the sixth grade, when helearned that magnesium could combust water.

Smith said hydrogen fuel may provide U.S. motorists a means of alternative energy for theirvehicles without having to eliminate the cars they love.

The public can start viewing the new invention at 9am, next Thursday. The awards ceremonystarts at 6pm, and admission is free.
