Tesla to use laser beams instead of windscreen wipers

Date:13 December 2019 Author: Lucinda Dordley Tags:,

Earlier this week, Tesla announced it has filed a patent to use high-tech windscreen wipers over the traditional aluminium and rubber sort. The electric car manufacturer believes using laser beams to clean windscreens is much more efficient, as it eliminates all dirt, unlike normal wipers.

The patent was recently filed with the United States Patent and Trademark Office, and stipulates that the process of removing dirt and debris with laser beams will not hurt the eyes of the car’s occupants. It also claims the process of removing dirt will take up less time than removing dirt with water and soap.

The patent goes on to explain how any glass surface on the car may be cleaned by the lasers, and this includes the cameras and sensors used for autonomous driving.

“The cleaning apparatus may be installed as a modular device in a vehicle and may provide a contactless means to clean different glass articles, for example, windshields, in-vehicle camera lenses, side windows, rear-view mirrors, and the like,” the patent reads.

Tesla is known for its history of pioneering new vehicle technologies, including its famous electric cars and their self-driving capabilities.

“Too often these days [patents] serve merely to stifle progress, entrench the positions of giant corporations and enrich those in the legal profession, rather than the actual inventors,” Musk said in a blog post. “Tesla was created to accelerate the advent of sustainable transport. If we clear a path to the creation of compelling electric vehicles, but then lay intellectual property landmines behind us to inhibit others, we are acting in a manner contrary to that goal.”
