Tesla’s a Game Changer When It Comes to Windshield Wipers
Electromagnetic blades are typical Tesla weirdness and innovation right in front of your face.

- Tesla has applied for a patent for a new electromagnetic windshield-wiper system that has a single wiper blade.
- The new system is designed for better wiping efficiency—and killer good looks, according to the patent application.
- Not for nothing, but the design also reduces the amount of battery charge needed to run the wiper function.
The last car part you'd ever think would change is being revolutionized by Tesla, which has filed a patent for a new windshield-wiper design. The basic windshield wiper hasn't changed in a long time. It's just a small gear set that rotates back and forth to move the wiper blade across the windshield. Sure, wiper blades have gotten more advanced as manufacturers have learned how to make better contact with the windshield and keep the view out less streaky, but Tesla shows in this patent application that it's looking at the problem in a fresh way.
MORE TESLA NEWSPublished on September 5, Tesla's patent filing describes an "electromagnetic wiper system for the windshield of a vehicle." This single-blade design is supposed to be more efficient and better-looking, according to Tesla's description, although from the drawings it appears it could also be adapted to a dual-blade setup. It works using electromagnets and guide rails. Picture high-speed maglev trains, named for the magnetic levitation they use to move quickly and efficiently from place to place; it's like that on a smaller scale.

Tesla Model S Spotted Lapping the Nurburgring

Did a Tesla Model S Really Set a Lap Record?
Tesla's design involves a block attached to the wiper arm and blade. The arm is connected to two guide rails to keep the system in place and to ensure that the blade makes contact with the windshield. The block is how the entire arm-and-blade assembly moves, since the block moves on a set of magnets surrounded by electromagnetic coil. When a current passes through the magnet and coil, the block will move across the windshield and take the arm and blade along with it.

It's no small point on an EV that, with this system, the wiper needs to draw less power from the car's battery. Tesla mentions that the mechanical components of the traditional wiper blade create a lot of friction, which requires more power to the motor that moves the arm back and forth. Electromagnets are essentially frictionless, so the only friction in Tesla's wiper system is from the guide rails on which the arm slides. This reduction in power being drawn could increase the already astonishing 370-mile driving range of a Long Range Tesla Model S, but we'll have to wait and see for ourselves to know how much of a difference this makes.
Tesla was also thinking about its Autopilot system when conceptualizing the patent for the wiper system. The argument is that traditional wiper systems aren't as robust as this new electromagnetic system; time and weather can lead to corrosion, making the traditional setup less effective over time. The resulting lack of visibility could hamper Autopilot and other autonomous-driving aids that use cameras to track lanes and objects around the car. Better visibility is better for the cameras and, of course, for the driver.
At the end of the day, Tesla is doing what it does best: revolutionizing. Having vastly expanded the idea of what an electric vehicle can be, the company appears to be taking that same mindset to the details, like windshield wipers.

Tesla is arguably the best at EV efficiency, which can be measured by MPGe. It’s a bunch of little things to improve aero and rolling resistance. I think Tesla is here to stay, but also think the stock price is wacko

Tesla is definitely the brand that made electric cars not only viable, but cool. No doubt helped along by those YouTube guys drag racing them and owning everybody. The EU is banning all internal combustion engine car sales by 2035. I know companies like Ferrari and Lamborghini are applying for exemptions there, but it will be interesting to see how this progresses. I think the battery technology still needs to progress a long way before they can fully replace gasoline and diesel vehicles.
Audi and Porsche now have shifting transmissions in their electric vehicles, which is interesting.

At first I thought the genius of Tesla was selling luxury electric cars. Everyone else tried to sell economy electric cars for BMW 3 series money. Starting up market was smart, but it turns out Tesla is good at the electric part

When Tesla began selling that roadster model in the beginning, I didn’t think that would lead into what they are today. Tesla is an American company and I think it’s great that they’re ahead of the game in electric power. Whether we like it or not, electric cars will be a reality for all of us in the future. I maintain that battery technology needs to make major leaps first for them to be viable for most people.

My brother who bought a S almost 5 years ago said that Elon said the initial buyers like himself would be paying a higher price
because they had to spend a lot to install the electrical charging infrastructure to support their cars, Ed said he paid $108,000
and the same model today is $20,000. cheaper and a better car.
But he was frank and honest how often do we see that with someone trying to sell you something.We have invented the world; WE see
