Tesla files patent for lasers that clean glass, could replace car windscreen wipers

Article from Wired

Wired said:
The electric automaker shuns lasers for its self-driving features. But a patent application foresees using the technology to clean windshields and cameras.

---

A newly published patent application, for which Tesla filed in May, describes the “pulsed laser cleaning of debris” that tends to gather on car windshields and solar panels.

---

While windshield wipers may do the job for most people, Tesla’s patent application notes that the process of scrubbing away grime and letting the glass dry results in “unproductive time,” and that the chemicals in wiper fluid could damage a camera’s electronics. Using a laser to burn off any unwanted muck, the patent argues, would be faster and more likely to keep everything working as intended.
Elon also has plans for a revolutionary new car wash idea...

So it doesn't sound like these would actually deal with rain but just grime that would build up on a windshield over the long term?

I think it was McLaren wanted to have their cars with ultra sonic force field to replace wipers but don't know what ever happened to that idea.

How can Tesla solve the problem of lasers causing permanent damage to people's eyes???:


A 9-year-old boy in Greece permanently injured his left eye when he repeatedly gazed into a laser pointer's green beam, doctors say.

Examination revealed a large hole in the macula, a small area in the retina that helps with discerning detail in faces and while reading or driving, the doctors said in a case report published in the New England Journal of Medicine. Further imaging revealed two more injured areas below the macular hole.

Macular holes are typically treated with surgery that is accompanied with an almost 100% risk of cataract formation, Dr. Sofia Androudi, a physician involved with the case, wrote in an email. Cataracts cause blurry vision by clouding the eyes' clear lenses.

However, in this case, because the macular hole resulted from the laser burn, the nerves in the eye that absorb light were totally damaged, said Androudi, an assistant professor of ophthalmology at the University of Thessaly in Greece. "This means that even if the surgery would be successful, the boy would not be able to see."

The boy's vision was measured at 20/20 in his right eye and 20/100 in his left, according to the report. A person with a visual acuity of 20/100 would have to be within 20 feet of a point of focus in order to see what a person with normal vision can see at 100 feet.

See, the idea of using lasers for this is stupid, but this isn't a good argument. Technically cars can kill people, but that's not the use they're being sold for. Which is also to say, you shouldn't be pointing lasers at people's eyes.

So lasers strong enough to melt debris... in front of the unprotected eyes of drivers and passengers...

What could possibly go wrong?

Self driving cars that don't take dents now with destructive lasers. What could possibly go wrong. The automated factory is nearly online sir Skynet, just a few adjustments...

ITT people who don't realize patents don't mean an idea will be used or that the obvious "issues" they bring up weren't already brought up or considered

So uh, Elon heard the Top Gear joke about Lancia using laser beams to clean the windshield and decided "hey great idea"?

Not sure how they'll prevent eye damage from the beams there, but if they can actually manage a working system it'd be interesting to see.

I always thought it should be something like horizontal Kevlar threads that cycle around the windscreen. Wipers do feel oddly old fashioned. Anyone ever use Rain-X?

all lasers are not equal

so to answer your question, they could use a very low wattage and not point it at people’s eyes for starters

disclaimer: I am not a laser

You people think this is like a robotic arm that raises up and beams straight into to the vehicle? Come on. Lol.

This sounds like a reasonable thing to have for camera and solar panel installations.

Windshields I'm not so sure about.

Sounds safe. Rock chips in the windshield won't scatter the laser to anyone's eyes I'm sure.
Headlights sound safe. Your lights hitting someone crack and spreading then bouncing around inside their eye destroying all rods and cones in it's path!

Jesus. We seriously worried about some fringe case that would happen .0000000000001% of the time? Come on.

Most people in this thread must use this song as a theme song:

I'm more interested in what solution they have for the cybertrucks wing mirrors short of just sticking some cameras on sticks to its doors, but that would ruin its lines...

Elon Musk is an asshole, so yes.



Did Gabe Newell ever call anyone a pedophile for saying Steam was a bad idea?
Nope, but the original outrage at steam started because people were upset their favorite porn visual novels might be banned and valve didn't give a bullet point list detailing exactly every single possible scenario why their favorite 1000 year old dragon vn's wouldn't be allowed on the store.

People here really hate Tesla/Musk, huh?
Seriously. People's perception of Musk makes them revert to some Amish/Mennonite who think technology is some evil force. If this was the 1800s and someone tried explaining the internal combustion engine to them they'd scoff at the idea of using small explosions to push a horseless carriage.
