You know that to propel your car you are basically blowing up gasoline in your engine right? Well currently that is being done with a spark plug (or glow plug in the case of diesel) and it is (apparently) not the most efficient method. What is more efficient is firing lasers at the explosive mix — sounds cool.

Better yet if I read this article right there are two benefits to replacing spark plugs with laser guns1 :

  1. Better fuel efficiency.
  2. More power.

Number two is what interests me.

  1. Not really laser guns, but hey these things show lasers so am I that far off?
