Tesla could replace its windshield wipers with laser beams

Say whatever you want about Tesla, but they’ve got some absolutely crazy ideas. In 2019, Tesla filed for a patent for laser beam window cleaners, and it was just approved this week.

The full name of the patent is “Pulsed laser cleaning of debris accumulated on glass articles in vehicles and photovoltaic assemblies”, suggesting its use also for solar panels. This makes sense because dirt build-up is a big problem when it comes to photovoltaic (PV) solar cells. The system would have sensors that would detect when dirt has built up and emit a laser until the dirt burns off.

Using pulsed lasers would help minimize damage to any other subject as it decreases the intensity of the laser. The patent states that the pulse “limits the penetration of the laser beam to a depth less than the thickness of the glass article” so that the driver would have nothing to worry about. Still, if these lasers are powerful enough to burn off dirt, hopefully they’re calibrated correctly. This could be a concern, as Tesla isn’t exactly known for perfect build quality and reliability.

Replacing the current and accepted design of windshield wipers is a good idea, but some have been blown away, saying the idea is just too unattainable at the moment. Critics have called it a “speculative patent,” that is, a patent that seeks to profit from future implementations of the idea without providing practical solutions. We have yet to see a practical demonstration of the laser wipers.

Since the Cybertruck was not seen with windshield wipers, laser beams could be the method used in the final design. However, Tesla filed another patent that would be much more practical: electromagnetic wipers.

Tesla seems to be quite unhappy with the conventional wiper design. In the electromagnetic wiper patent, they say that “Conventional wiper systems that use multiple wiper blades generally have a cluttered design and do not clear the windshield enough, which can hamper the windshield. field of vision clear of the path to be traveled. “

Their proposed design would only use a single side-to-side wiper blade, powered by a linear actuator. Apparently this would be more energy efficient and minimize friction.

Other Tesla patents have been filed, such as the idea of ​​using lasers to bend glass structures, but we have to wait and see if Tesla actually brings any of those ideas to fruition.
