Tesla’s crazy laser windshield wipers have been published by the US Patent Office
Tesla’s idea for a crazy windshield wiper that would clear debris from a driver’s line of sight using a laser beam has been officially published by the United States Patent Office. Tesla filed the application for the patent in May 2019, and it finally was granted in late 2021. Now, the U.S. Patent Office has published the patent, making it publicly viewable.
Tesla has long been interested in some pretty crazy and revolutionary ideas for automobiles. Over the years, Tesla has looked at several different designs and ideas for windshield wipers, using anything from a single-wiper system for the Next-Gen Roadster that would utilize an electromagnetic linear actuator to rid the windshield of moisture, to no wipers at all when it unveiled the Cybertruck in November 2019. Most recent sightings of Tesla’s Cybertruck have indicated the vehicle will have wipers, but Tesla is still revising the design.
With all of the crazy ideas Tesla has thrown around for wipers in the past, the patent for the automaker’s “Pulsed Laser Cleaning of Debris Accumulated on Glass Articles in Vehicles and Photovoltaic Assemblies” is among the most interesting. Originally filed in May 2019, Tesla recently had the idea published by the U.S. Patent Office, meaning if the Office does not ultimately grant the patent, the public can still learn from the work and perhaps develop another system that could be granted.
Tesla describes the patent in the now-published filing:
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. The control circuitry calibrates a set of parameters associated with the laser beam emitted from the beam optics assembly based on detection of the debris accumulated over the region on the glass article, controls an exposure level of the laser beam on the debris accumulated based on calibration of the set of parameters associated with the laser beam, wherein the exposure level is controlled based on pulsing the laser beam at a calibrated rate that limits penetration of the laser beam to a depth that is less than a thickness of the glass article and removes the debris accumulated over the region on the glass article using the laser beam.”
It is not necessarily confirmed or known what plans Tesla may have for the laser windshield wipers, but illustrations within the patent do seem to display a Model S body. Tesla may be willing to test this type of apparatus on some of its vehicles in-house, but the automaker has never detailed specific plans for the idea.

Tesla’s flowchart describing the process for the patent is relatively simple, and also shows uses with clearing debris from solar panels. In five steps, the patent describes the use of the laser cleaning assembly:
- Detect debris accumulated on a region on glass article installed in vehicle
- Calibrate a set of parameters associated with laser beam emitted from beam optics assembly, based on detection of debris accumulated on a region on glass article
- Control exposure level of laser beam on detected debris accumulated on glass article based on calibration of set of parameters associated with laser beam
- Irradiate region associated with the detected debris on glass article by laser beam
- Remove detected debris accumulated on region by laser beam
It doesn’t appear to be operated by the vehicle itself, either. Tesla describes the potential for a manual system where the driver could control the laser with a touchscreen, joystick, or another medium to communicate with different operational components of the cleaning apparatus.
While it seems like an outlandish and potentially satirical idea, it would not be too far past Tesla’s realm of ideas to use a laser to clear a windshield. After all, CEO Elon Musk has said in the past that the Roadster will fly thanks to SpaceX cold gas thrusters, Tesla has filed a patent for the Cybertruck to have solar cells on its tonneau for additional electric vehicle range, and plenty of other insane ideas. However, the new laser patent, if ultimately used by Tesla, would only decrease the already-minimal maintenance costs owners deal with, as yearly keep-up costs on EVs are extremely low.

SpaceX issues statement on Starship V3 Booster 18 anomaly
The incident unfolded during gas-system pressure testing at the company’s Massey facility in Starbase, Texas.
SpaceX has issued an initial statement about Starship Booster 18’s anomaly early Friday. The incident unfolded during gas-system pressure testing at the company’s Massey facility in Starbase, Texas.
SpaceX’s initial comment
As per SpaceX in a post on its official account on social media platform X, Booster 18 was undergoing gas system pressure tests when the anomaly happened. Despite the nature of the incident, the company emphasized that no propellant was loaded, no engines were installed, and personnel were kept at a safe distance from the booster, resulting in zero injuries.
“Booster 18 suffered an anomaly during gas system pressure testing that we were conducting in advance of structural proof testing. No propellant was on the vehicle, and engines were not yet installed. The teams need time to investigate before we are confident of the cause. No one was injured as we maintain a safe distance for personnel during this type of testing. The site remains clear and we are working plans to safely reenter the site,” SpaceX wrote in its post on X.
Incident and aftermath
Livestream footage from LabPadre showed Booster 18’s lower half crumpling around the liquid oxygen tank area at approximately 4:04 a.m. CT. Subsequent images posted by on-site observers revealed extensive deformation across the booster’s lower structure. Needless to say, spaceflight observers have noted that Booster 18 would likely be a complete loss due to its anomaly.
Booster 18 had rolled out only a day earlier and was one of the first vehicles in the Starship V3 program. The V3 series incorporates structural reinforcements and reliability upgrades intended to prepare Starship for rapid-reuse testing and eventual tower-catch operations. Elon Musk has been optimistic about Starship V3, previously noting on X that the spacecraft might be able to complete initial missions to Mars.

Tesla analyst maintains $500 PT, says FSD drives better than humans now
The team also met with Tesla leaders for more than an hour to discuss autonomy, chip development, and upcoming deployment plans.
Tesla (NASDAQ:TSLA) received fresh support from Piper Sandler this week after analysts toured the Fremont Factory and tested the company’s latest Full Self-Driving software. The firm reaffirmed its $500 price target, stating that FSD V14 delivered a notably smooth robotaxi demonstration and may already perform at levels comparable to, if not better than, average human drivers.
The team also met with Tesla leaders for more than an hour to discuss autonomy, chip development, and upcoming deployment plans.
Analysts highlight autonomy progress
During more than 75 minutes of focused discussions, analysts reportedly focused on FSD v14’s updates. Piper Sandler’s team pointed to meaningful strides in perception, object handling, and overall ride smoothness during the robotaxi demo.
The visit also included discussions on updates to Tesla’s in-house chip initiatives, its Optimus program, and the growth of the company’s battery storage business. Analysts noted that Tesla continues refining cost structures and capital expenditure expectations, which are key elements in future margin recovery, as noted in a Yahoo Finance report.
Analyst Alexander Potter noted that “we think FSD is a truly impressive product that is (probably) already better at driving than the average American.” This conclusion was strengthened by what he described as a “flawless robotaxi ride to the hotel.”
Street targets diverge on TSLA
While Piper Sandler stands by its $500 target, it is not the highest estimate on the Street. Wedbush, for one, has a $600 per share price target for TSLA stock.
Other institutions have also weighed in on TSLA stock as of late. HSBC reiterated a Reduce rating with a $131 target, citing a gap between earnings fundamentals and the company’s market value. By contrast, TD Cowen maintained a Buy rating and a $509 target, pointing to strong autonomous driving demonstrations in Austin and the pace of software-driven improvements.
Stifel analysts also lifted their price target for Tesla to $508 per share over the company’s ongoing robotaxi and FSD programs.

SpaceX Starship Version 3 booster crumples in early testing
Photos of the incident’s aftermath suggest that Booster 18 will likely be retired.
SpaceX’s new Starship first-stage booster, Booster 18, suffered major damage early Friday during its first round of testing in Starbase, Texas, just one day after rolling out of the factory.
Based on videos of the incident, the lower section of the rocket booster appeared to crumple during a pressurization test. Photos of the incident’s aftermath suggest that Booster 18 will likely be retired.
Booster test failure
SpaceX began structural and propellant-system verification tests on Booster 18 Thursday night at the Massey’s Test Site, only a few miles from Starbase’s production facilities, as noted in an Ars Technica report. At 4:04 a.m. CT on Friday, a livestream from LabPadre Space captured the booster’s lower half experiencing a sudden destructive event around its liquid oxygen tank section. Post-incident images, shared on X by @StarshipGazer, showed notable deformation in the booster’s lower structure.
Neither SpaceX nor Elon Musk had commented as of Friday morning, but the vehicle’s condition suggests it is likely a complete loss. This is quite unfortunate, as Booster 18 is already part of the Starship V3 program, which includes design fixes and upgrades intended to improve reliability. While SpaceX maintains a rather rapid Starship production line in Starbase, Booster 18 was generally expected to validate the improvements implemented in the V3 program.
Tight deadlines
SpaceX needs Starship boosters and upper stages to begin demonstrating rapid reuse, tower catches, and early operational Starlink missions over the next two years. More critically, NASA’s Artemis program depends on an on-orbit refueling test in the second half of 2026, a requirement for the vehicle’s expected crewed lunar landing around 2028.
While SpaceX is known for diagnosing failures quickly and returning to testing at unmatched speed, losing the newest-generation booster at the very start of its campaign highlights the immense challenge involved in scaling Starship into a reliable, high-cadence launch system. SpaceX, however, is known for getting things done quickly, so it would not be a surprise if the company manages to figure out what happened to Booster 18 in the near future.
