Tesla patent laser beam cleaner for cars

Tesla's vehicles could one day be fitted with a laser beam that gets rid of dirt on the windscreens.

A patent for 'Pulsed Laser Cleaning of Debris Accumulated on Glass Articles in Vehicles and Photovoltaic Assemblies' has been filed in the United States.

The patent is for "a cleaning system for a vehicle includes a beam optics assembly that emits a laser beam to irradiate a region on a glass article of the vehicle, debris detection circuitry that detects debris accumulated over the region, and control circuitry".

And it is hoped that the new system could be "integrated with other cleaning solutions" included standard issue wipers, water, or air sprays or chemical solutions.

It read: "The cleaning apparatus provides a fast, robust, and chemical-free solution to clean different glass articles in vehicles and solar photovoltaic facilities. The solution can be integrated with other cleaning solutions that use wipers, water, or air sprays or chemical solutions to clean glass articles.

The filed patent would allow for these lasers to be used on all windshields, the car's side windows as well as its side and rear view mirrors.
