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.

Tesla Semi futuristic sci-fi acceleration sound will never get old

Videos that capture the Semi moving at speed are most notable due to their sheer cool factor.

The Tesla Semi is not yet in mass production, but the company has accumulated over 7.9 million miles across its test fleet. With Tesla using the Semi for its operations, it is no surprise that sightings of the Class 8 all-electric truck have been abounding. 

These sightings from Tesla enthusiasts vary, but those that capture the the Class 8 all-electric truck moving at speed are most notable, possibly due to their sheer cool factor.

Tesla Semi’s Roar

There is something that just stands out with the Semi, particularly on the road. While the Semi does not have the Cybertruck’s brutalist, angular design, it is still very striking because it’s such a massive machine that moves far too quietly for its size. This is, of course, one of the reasons why the vehicle also becomes extra noteworthy when it fires up its electric motors and accelerates.

Take this video from Tesla Owners Silicon Valley, for example, which shows the all-electric hauler accelerating while pulling what appears to be a full load. In these situations, the Tesla Semi actually becomes audible, but unlike traditional diesel-powered truck, the Class 8 all-electric truck “roars” with its own, unique futuristic, sci-fi sound. In such situations, one could feel the Semi’s raw power, which comes from its three independent motors on its rear axles.

Tesla Semi Ramp

Tesla has been promoting the Semi quite a bit as of late, and recent reports have suggested that the company is putting in a lot of effort to prepare the vehicle for its production in Nevada. Tesla’s Careers website has gone live with over 80 Semi-related job openings recently as well, and a recent report has suggested that Tesla has ramped the Semi’s factory workers in Nevada to over 1,000 employees.

The company has even shared an update video of the Semi factory’s progress near Giga Nevada, as well as the design of the vehicle’s new logo. The Semi’s updated logo is quite interesting as it features elements from the Tesla Model 3’s first logo, which was unveiled way back in 2016.

Elon Musk jokes he will join Mr Beast’s “100 Men vs 1 Gorilla” challenge

It’s a good sign, if any, that the overworked Musk is becoming a bit more lighthearted again.

Following the first quarter Tesla earnings call, CEO Elon Musk seems to have become a bit more relaxed—relaxed enough to joke about fighting a gorilla with 99 other people, at least.

It’s a good sign, if any, that the overworked Musk is becoming a bit more lighthearted again and not too busy picking fights with politicians on social media.

The Viral 100 Men vs 1 Gorilla Challenge

Over the weekend, a post on social media platform X went viral. The post itself was quite simple, with user @DreamChasnMike stating that he thinks 100 men could beat one gorilla. “Everybody just gotta be dedicated to the sh*t,” the X user joked. The post exploded on the platform, garnering 284 million impressions as of writing.

The silly question also triggered a massive debate about whether 100 men would really stand a chance against a literal gorilla. Some users even lamented that the premise was a sign of male hubris. Nevertheless, the question proved to be a fun topic on X, with some more dedicated users even posting simulated videos of what the “100 Men vs 1 Gorilla Challenge” could look like. 

Mr. Beast and Elon Musk Join In

The premise is quite similar to other viral videos from noted YouTube creator Mr. Beast, so it was no surprise that edited images of Mr. Beast YouTube thumbnails with “100 Men vs a Gorilla” also started spreading on the social media platform. Mr. Beast, who tends to be game to such silly ideas, actually reposted the edited image, joking “Need 100 men to test this, any volunteers?”

In true Elon Musk fashion, the Tesla and SpaceX CEO noted that he would join the challenge. “Sure, what’s the worst that could happen” Musk wrote in his post on X. Musk’s reply triggered quite a few laughs on X, with some stating that the world probably still needs the CEO.

While silly, Musk’s comment and his recent, more frequent posts about his companies’ products like Starlink and Grok have been received well by his supporters. Over the past months, after all, Musk has been very political and quite confrontational on social media. With Musk soon taking a step back from the Department of Government Efficiency’s (DOGE) daily operations, however, it seems like X will soon get a more tempered and lighthearted Elon Musk once more.

Possible first glimpse of Tesla “Model 2” affordable car in Fremont Factory

The models that Tesla will release in the coming months will resemble the company’s current lineup.

During the Q1 earnings call, Tesla VP of Vehicle Engineering Lars Moravy set expectations on the design of the affordable models that the company is expected to launch this 2025. As per the Tesla executive, the models that Tesla will release in the coming months will resemble the company’s current lineup.

Drone footage from the Fremont Factory earlier this month might have provided the EV community its first potential glimpse at Tesla’s affordable cars–fondly dubbed by EV fans and analysts as the “Model 2” or even “Model Q”–or at least their components and overall shape.

The Sighting

Tesla watcher and drone operator Met God in Wilderness, who has been posting aerial videos of the Fremont Factory for years now, recently shared some footage from his drone flyovers this month. While the Fremont Factory was abuzz with activity as usual, a couple of rather strange vehicles were quickly spotted by EV watchers on social media.

During the drone operator’s flyover on the 17th, for example, an unfinished vehicle could be seen parked next to what appeared to be fully-built Model S and Model Y units. What was especially interesting was the vehicle’s roof, which seemed to be slightly narrower than the Model Ys around it. Based on the video, at least, the vehicle seemed to be shaped like a crossover as well.

Footage from the 24th of April also proved quite interesting, with the drone operator capturing footage of another cryptic vehicle. Unlike the mysterious, unfinished, crossover-esque car spotted on the 17th, this particular unit seemed to have a more sloping rear, at least based on the shape of its covering.

What Lars Moravy Said

In Tesla’s Q1 2025 Update Letter, Tesla noted that “plans for new vehicles, including more affordable models, remain on track for start of production in the first half of 2025.” Tesla also noted that the new vehicles will utilize aspects of its next generation and its current platforms. They will also be produced on the same manufacturing lines as its present vehicle lineup, likely the Model Y and Model 3. 

During the earnings call itself, Moravy specifically stated that the new models that would come out in the next months would resemble the company’s current vehicles. They will, however, be affordable. “Models that come out in next months will be built on our lines and will resemble, in form and shape, the cars we currently make. And the key is that they’ll be affordable, and you’ll be able to buy one,” Moravy stated.

Watch the drone operator’s footage from April 17 below.
