Laser Spark Plugs Could Cut Auto Emissions

BALTIMORE (AP) — Laser spark plugs could help cut emissions from your car.

That’s what Japanese researchers say, and they plan to discuss their new laser spark plug system Monday at an Optical Society conference in Baltimore.

Lasers strong enough to use as spark plugs have been too big to fit under a car hood until recently. But the researchers say they are now small enough to screw in like conventional spark plugs.

Laser spark plugs are more powerful, so they don’t need as much fuel to create the explosion that pushes the pistons inside engines. The lasers can also be aimed at the center of cylinder, not the top where current spark plugs sit, further increasing efficiency. And laser spark plugs can be made inexpensively from ceramics.

    Just a a point and a few questions: This is not a story of reference. Who is researching these spark plugs. Will these sparck plugs reach the market at a reasonable price. If they are so efficient, how much less fuel, comparitably, will they use percentage wise verses regular spark plugs. Will these spark plugs be usable in all vehicle models, gas or propane even? Have any order been put in for these spark plugs by any auto manufacturers? What country will these spark plugs be manufacturered? What is the expected work life of these spark plugs compared to other models of spark plugs? Will present auto manufacturers resist supporting these types of spark plugs? will aircraft to lawn moyers use these spark plugs?

    Will these spark plugs stop the state of Maryland from charging a fee to go the rip off spot I call emissions testing?
