Tesla’s patent for a stealthy, electromagnetic wiper is perfect for the new Roadster
A recently published patent application from Tesla has revealed that the electric car maker is designing a stealthy, unconventional windshield wiper system that seems particularly tailor-fit for the company’s upcoming halo car: the next-generation Roadster. Apart from looking the part of a futuristic wiper assembly for a futuristic vehicle, Tesla’s patent also allows optimizations in range.
As background, Tesla noted that conventional wiper systems usually utilize electric motors that move one or more wiper blades to clean the windshield of a vehicle. The assembly of such systems involves several mechanical components such as gears and bearings, which, in turn, enable the wiper blades to slide across the windshield.
This sliding motion of the mechanical components creates significant friction during operation. This results in the need for additional power to be supplied by a car’s in-vehicle battery, thereby reducing an electric vehicle’s range. Traditional wiper systems are usually prone to rust and wear as well, which could bog down a wiper assembly and make it inefficient in cleaning a windshield. This could be an issue in regions that experience a lot of rain or snow.
With this in mind, Tesla argues that there is a need to design an innovative windshield wiper system that cleans better, and lasts longer. Such a system was outlined in a recently published patent, plainly titled “Electromagnetic Windshield Wiper System.” Tesla’s design for its electromagnetic windshield wiper system involves the use of a “linear actuator that may include a guide rail and an electromagnetic moving block.” The design is modular, enabling easy installation. The wiper arm and blade could be attached to each other as well, forming a “linear mono wiper in an uncluttered design.” Tesla describes how its windshield wiper assembly works as follows.
“The disclosed electromagnetic wiper system may include a linear actuator that may include a guide rail and an electromagnetic moving block. The guide rail may include a plurality of permanent magnet bars that may be disposed horizontally along a curvature of the windshield of the vehicle. The electromagnetic moving block may act as an electromagnetic train, and may include a plurality of perforations and at least an electromagnetic coil that surrounds the plurality of perforations in the electromagnetic moving block.
“The linear motion of the electromagnetic moving block through the plurality of permanent magnet bars may be controlled to steer the wiper arm that may be coupled to the electromagnetic moving block, back and forth across the entire length of the windshield to wipe a defined region, for example, the entire transparent area (i.e., near cent percent area) of the windshield. This may result in minimal friction during the linear motion of the electromagnetic moving block.”
What is pretty interesting about Tesla’s electromagnetic windshield wiper patent is that the entire mono wiper assembly stows away beneath the hood of a vehicle when not in use. This, apart from giving an electric car windshield a clean, uncluttered look, improves a car’s aerodynamic performance during operations. Tesla notes that these optimizations will be particularly significant at high speeds.
Tesla did not state which of its present or upcoming vehicles will be using the electromagnetic windshield wiper system outlined in the recently published patent. That being said, a look at the benefits of Tesla’s design suggests that the innovative wiper system will be a perfect fit for the next-generation Roadster.
The Roadster’s static models sported a conventional wiper system, after all, and they look almost out of place in such a futuristic vehicle. Considering that the new Roadster is Tesla’s halo car, it makes perfect sense for the company to go all out in its optimizations, windshield wipers included. Couple that with the Roadster’s emphasis on aerodynamics and high-speed driving and this patent makes even more sense for the all-electric supercar.

SpaceX’s biggest earnings test yet lands Tuesday, and Tesla shareholders should be watching
SpaceX reports earnings Tuesday as Wall Street watches AI spending, Starlink growth and Tesla merger
SpaceX reports third quarter results after the market closes Tuesday, with a webcast at 4:30 p.m. ET streamed on X, and Tesla follows a day later. Bloomberg consensus, cited by Pepperstone, calls for revenue of $12.89 billion, adjusted EBITDA of $6.62 billion and adjusted EPS near $0.15. That would be about 65% growth from the second quarter and SpaceX’s first profitable quarter since its IPO. Analysts expect roughly $6.4 billion from AI and $4.9 billion from Starlink, which is projected to reach 14.3 million consumer subscribers. Capital spending is forecast at $19.6 billion, leaving free cash flow near negative $11.6 billion.
The numbers matter because SpaceX has spent months trying to win over a skeptical market. It priced its record IPO at $135, spiked to $225.64, then sank near $105 in early August. Friday’s close of $146.03 sits about 28% below the June high. The Q2 report beat on revenue at $7.8 billion and put Starlink at 12 million subscribers, but $18.4 billion of capex hurt the stock. Since then SpaceX reached orbit on Starship Flight 14 with 26 Starlink V3 satellites, agreed to buy 800 MHz spectrum for about $8 billion as part of its Starlink Mobile push, and signed a fourth compute hosting deal in four months worth roughly $13 billion a year from December. Management is targeting more than 2 gigawatts of compute by year end and a $100 billion annualized revenue run rate. Evercore ISI, which raised its target to $275, said the quarter may be judged more on those targets than the reported figures
All of this sits under the Tesla merger question. Barclays analyst Dan Levy expects an all stock deal in which SpaceX buys Tesla at a premium, using reference values of $2.1 trillion and $1.5 trillion, and said an announcement would need to come by late October or early November to be voted on at Tesla’s December 6 annual meeting. Barclays estimates Musk would hold about 37% of the combined company and 56% of the votes. Musk said in July that combining companies cannot be discussed on an earnings call, but an investor question asking when SpaceX will merge with Tesla is sitting on SpaceX’s Q&A platform, and Teslarati has tracked how the Roadster demo revived the talk.
If a deal happens, Tuesday’s result would effectively set the price Tesla holders would receive. Their shares would convert into SpaceX stock, along with exposure to a company with a heavy investment on AI, while Tesla itself expects 2026 capex above $25 billion. A strong quarter and calmer spending would make that exchange easier to sell. Another round of heavy capex and a falling stock would make it harder.

SpaceX’s Gwynne Shotwell just made a quiet gesture toward Tesla
SpaceX president Gwynne Shotwell quietly followed Tesla on X, and merger watchers noticed right away.
SpaceX President and COO Gwynne Shotwell has started following Tesla’s official account on X, a small change that landed in the middle of a very loud merger conversation. Whole Mars Catalog joked about it on Sunday.
A follow is not an announcement, and neither company has said anything about a deal. What gives the moment weight is the timing. Barclays analyst Dan Levy has told clients that an agreement could come before Tesla’s annual meeting, which must be held by December 6, with SpaceX as the buyer in an all stock deal, as we reported after the Roadster unveiling. Wedbush’s Dan Ives has stuck with a 2027 timeline.
“Shit, I better start following their X account if i’m gonna be helping run the company”

Shotwell is the executive most worth watching if the two companies do move closer. When Musk was asked at the All In Summit why Tesla and SpaceX remain separate, Shotwell sat next to him and said SpaceX personnel had already moved into xAI to fill leadership and engineering gaps. The businesses were integrating “faster than I thought,” she said, though “not fully integrated yet.” Her responsibilities have also grown since SpaceX absorbed xAI, and she now oversees operations that include Grok and the company’s AI compute buildout.
The financial links are already there. Tesla’s $2 billion xAI investment turned into a stake of less than one percent in SpaceX, the two share the Terafab chip project in Austin, and Musk exercised his 2018 Tesla options a week after SpaceX began trading, a sequence analysts flagged as giving SpaceX public shares to use in a deal. Musk holds about 20 percent of Tesla and controls 85.1 percent of SpaceX’s voting power, according to our earlier breakdown.
The next test is close at hand. SpaceX reports its second earnings as a public company on Tuesday after the close, and Tesla follows on Wednesday. Musk told analysts in July that “we can’t talk about combining companies and that kind of thing on an earnings call,” so a direct answer is unlikely from either stage. Tesla shareholders can still submit and vote on questions through the Say portal until 4 p.m. EDT on Monday, and the merger is a recurring theme in the queue.

Tesla Roadster owners to get “Flying Stunt Mode” and looping track access
Musk says Roadster owners can command the unveiling stunts autonomously, with a Texas looping track.
Elon Musk says owners of the new Tesla Roadster will be able to ask the car to perform the stunts Tesla showed at its unveiling, with the car doing the driving itself. Musk made the comment Saturday in a reply on X to tech blogger Robert Scoble, and he added a promise of a looping track at Tesla’s Texas headquarters.
Scoble had argued that the person in the Roadster is not really driving it. In his description, the driver operates a computer that tells another computer what to do, with steering, braking and acceleration all handled by wire. Musk answered, “True. You will be able to ask the Roadster to perform any of the tricks shown autonomously, as it will be sentient. Also, we will have a wild looping track (crazier even than Hot Wheels) at our Texas HQ where you can test out your Roadster.”
@Scobleizer True.

At the October 15 event outside Waco, the car drove up a curved ramp until it was upside down, flew off on cold gas thrusters, flipped and landed. It also hovered over a Cybercab, Cybertruck, Semi, Model Y and Model 3 while moving. As we noted in our breakdown of the three Roadster configurations, Musk said at the event that the car “literally is just going to puff itself up” to perform the maneuvers whenever an owner wants. Saturday’s reply adds that the car would run them on its own.
Tesla has described some of the hardware that would make that possible. The Roadster uses steer by wire with a yoke, and its cold gas thrusters rely on electric actuators for small adjustments in flight. A fan system under the car creates suction, which Tesla says is strong enough to hold it upside down, a setup we covered in our look at the Roadster’s fan system and thrusters.
Musk did not say when an autonomous stunt feature might arrive, how it would work, or what he means by sentient. He also gave no size, location or opening date for the Texas track. Production is planned for Giga Texas in 2027 or 2028, and Tesla says the car is not approved for public road use. The Rocket version, the one built to fly, is invite only.
The comment follows a week of Musk teasing the event, including his claim that the demo would be a banger, which we covered before the stream. Tesla reports third quarter earnings on October 21, and shareholders can submit and vote on questions through the Say portal until 4 p.m. EDT on October 20, according to our earnings Q&A preview. A question about autonomous Roadster stunts and the Texas track would be a quick way to get specifics from management.
