Laser Spark Plug


  • Car engines could soon be fired by lasers instead of spark plugs, researchers say.
  • The approach would increase efficiency of engines, and reduce their pollution, by igniting more of the mixture.
  • The team has been developing a new approach to the problem: lasers made of ceramic powders that are pressed into spark-plug sized cylinders.
