Researchers have developed a system of lasers that are small enough to replace the spark plugs in car engines.
The new lasers were created by Japanese researchers, and could enable a car's engine to burn more efficiently, cleaner, and with less smog producing nitrous oxide emissions. Previous laser systems have not been small enough to work with the spark plugs, but the new lasers are both small and powerful . They are also inexpensive to make, and can be mass produced.
