Laser energy may soon be replacing spark plugs to make engines more efficient and environmentally friendly said a team of researchers from Romania and Japan. The team was said to be in talks with the Denso to commercialize products that look to be starting a revolution in the auto industry. They say that the cheap laser capable of lighting the fuel and air mixture in the combustion chamber of the engine. Disclosure would be made at the Conference on Lasers and Electro-Optics in Baltimore. Spark plug not received a lot of changes since created 150 years ago. One of the great weaknesses of the iron, which she had eroded over time. Previously, researchers found that laser needed to take over the spark plug is large and takes up space, as well as unstable and inefficient. However, the issues were resolved with the use of ceramic powders.
