For more than 150 years, spark plugs have powered internal combustion engines. Automakers are now one step closer to being able to replace this long-standing technology with laser igniters, which will enable cleaner, more efficient, and more economical vehicles. Researchers from Japan have developed the first multibeam laser system small enough to screw into an engine's cylinder head.
