Tesla Roadster’s revolutionary wiper design secures U.S. Patent approval
The United States Patent Office has approved Tesla’s revolutionary electromagnetic wiper design for the next-gen Roadster, documents show.
U.S. Patent Office documents reveal that patent number 10,889,267, the “electromagnetic windshield wiper design system” submitted by Tesla on March 5th, 2018, has been approved. Tesla published the patent over a year later on September 5th, 2019, and it was approved on January 12th, 2021.
Tesla’s Electromagnetic Wiper for the Roadster
Tesla’s patent shows a one-piece wiper design that is not typical or similar in any fashion to the “normal” two-piece windshield wiper architecture. Most vehicles, including all four of Tesla’s current lineup of cars, use two wipers that operate from the bottom of the windshield in an arc shape. This gives the driver coverage of the field of vision of the car they are operating, but it does not clear every raindrop from the surface of the glass. The top two corners, along with some other areas, are not affected by the traditional wiper design or range of motion.
However, Tesla wanted to install something slightly different onto its next-gen Roadster, which could be the fastest car to ever navigate on public roads. Instead of the traditional two-wiper blade design, Tesla’s patent details a one-piece wiper system that uses an electromagnetic linear actuator to rid the windshield of any rain or moisture completely. It will start from one side and move directly to the other side, cleaning the entire windshield with one motion.
The patent states:
“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.”
When the wiper blade is not being used, it will be hidden under the car’s hood. This adds to the Roadster’s clean and modern design, free of anything that could take away from its aerodynamically-advantageous design, including side-mirrors.
U.S. Patent Office Grants Approval
The United States Patent Office officially granted approval on January 12th, documents show.
“U.S. patent number 10,889,267 [Application Number 16/291,186] was granted by the patent office on 2021-01-12 for electromagnetic windshield wiper system. This patent grant is currently assigned to Tesla, Inc.. The grantee listed for this patent is Tesla, Inc.. Invention is credited to Nicolas Clift, Gonzalo Espinoza Graham, Maithreya Kedambadi Prasanna.”

Roadster Updates from Musk
Earlier this week, Tesla CEO Elon Musk gave some updates regarding the Roadster project, which has been delayed several times due to engineering modifications and battery constraints. Musk told Joe Rogan during his third appearance on the JRE Podcast that he wants the Roadster to hover and that he is still trying to figure out how to make that happen.
Musk said:
“I want it to hover. I’m trying to figure out how to make this thing hover, without, you know, killing people. I thought, maybe we could make it hover, but not too high. So maybe it could hover, like, a meter above the ground, or something. So, if you plummet, you blow out the suspension, but you’re not going to die. Maybe, I don’t know, six feet. If we put a height limit on it, it will probably be fine.”
Regardless of the Roadster will hover or not, Musk still plans to release a SpaceX package that will give three tons of thrust for insane acceleration. During the Q4 2020 Earnings Call, he also stated that production would likely begin next year.
Finishing engineering this year, production starts next year. Aiming to have release candidate design drivable late summer. Tri-motor drive system & advanced battery work were important precursors.

Elon Musk offers to pay TSA salaries as government shutdown leaves agents without paychecks
Elon Musk offered to personally cover TSA salaries as the DHS shutdown deepens travel chaos nationwide.
Elon Musk says that he is willing to personally cover the salaries of Transportation Security Administration (TSA) workers caught in the crossfire of a partial government shutdown that has now dragged on for over a month. “I would like to offer to pay the salaries of TSA personnel during this funding impasse that is negatively affecting the lives of so many Americans at airports throughout the country,” Musk wrote.

The offer arrives as Congress let funding expire for the Department of Homeland Security on February 14, amid a disagreement over immigration enforcement, leaving most TSA employees classified as essential and on duty but working without pay. The timing could not be more disruptive, as the shutdown is colliding directly with spring break travel season when millions of Americans are in the air.
This is not the first time TSA workers have endured this kind of hardship. TSA agents are being asked to work without pay until congressional action unblocks their paychecks, having previously held out through the longest government shutdown in U.S. history at 43 days. The pattern reveals a systemic failure in how Congress funds critical security infrastructure, and Musk’s offer shines a spotlight on that recurring failure at a moment when the public is directly feeling its effects through long lines and terminal closures.
Whether Musk can legally follow through remains unclear, as federal law generally prohibits government employees from receiving outside compensation related to their official duties.

Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry
Tesla, SpaceX, and xAI unveiled TERAFAB, a $25B chip factory targeting one terawatt of AI compute annually.
Elon Musk took the stage over the weekend at the defunct Seaholm Power Plant in Austin, Texas, to officially unveil TERAFAB, a $20-25 billion joint venture between Tesla, SpaceX, and xAI that he described as “the most epic chip building exercise in history by far.” The announcement marks the most ambitious infrastructure bet Musk has made since Gigafactory 1 in Sparks, Nevada, and it fuses three of his companies into a single, vertically integrated AI hardware machine for the first time.
TERAFAB is designed to consolidate every stage of semiconductor production under one roof, including chip design, lithography, fabrication, memory production, advanced packaging, and testing. At full capacity, the facility would scale to roughly 70% of the global output from the current world’s largest semiconductor foundry from Taiwan Semiconductor Manufacturing Company (TSMC).
Elon Musk’s stated goal is one terawatt of computing power annually, split between Tesla’s AI5 inference chips for vehicles and Optimus robots, and D3 chips built specifically for SpaceXAI’s orbital satellite constellation.
Tesla Terafab set for launch: Inside the $20B AI chip factory that will reshape the auto industry
The logic behind the merger of these three entities is rooted in a supply chain crisis Musk has been signaling for over a year. At Tesla’s Q4 2025 earnings call, he warned investors that external chip capacity from TSMC, Samsung, and Micron would hit a ceiling within three to four years. “We’re very grateful to our existing supply chain, to Samsung, TSMC, Micron and others,” Musk acknowledged at the Terafab event, “but there’s a maximum rate at which they’re comfortable expanding.” Building in-house was, in his framing, not a strategic option, but a necessity.
The space angle is where the announcement becomes genuinely unprecedented. Musk said 80% of Terafab’s compute output would be directed toward space-based orbital AI satellites, arguing that solar irradiance in space is roughly 5x greater than at Earth’s surface, and that heat rejection in vacuum makes thermal scaling viable. This directly feeds the SpaceXAI vision, which is betting that within two to three years, running AI workloads in orbit will be cheaper than doing so on the ground. The satellites, powered by constant solar energy, would effectively turn low Earth orbit into the world’s largest data center.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
Historically, this announcement threads together every major Musk initiative of the past two years: the xAI-SpaceX merger, Tesla’s $2.9 billion solar equipment talks with Chinese suppliers, the 100 GW domestic solar manufacturing push, the Optimus humanoid robot program, and Starship’s development. TERAFAB is the capstone that ties them into a single coherent architecture — chips made on Earth, launched by SpaceX, powered by Tesla solar, run by xAI, and ultimately extended to the Moon.
“I want us to live long enough to see the mass driver on the moon, because that’s going to be incredibly epic,”Musk said during the presentation.
