Lasers Could Replace Spark Plugs, Increasing Efficiency, Cutting Emissions

Researchers based in Roma­nia and Japan have devel­oped a laser sys­tem that could replace bread-and-but­ter of vehi­cles’ motors — spark plugs. The researchers say their sys­tem uses small lasers that focus beams into cylin­ders at vary­ing depths, allow­ing for more com­plete com­bus­tion than occurs w/ con­ven­tion­al spark plugs, increas­ing effi­cien­cy and cut­ting emis­sions.
