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.

CEO of Tesla Elon Musk revealed in tweets posted on Saturday that he is giving serious thought to creating a social media platform.

“Given that Twitter serves as the de facto public town square, failing to adhere to free speech principles fundamentally undermines democracy,” Musk further tweeted.

Free speech

Meanwhile, on Friday, he put out a Twitter poll asking users if they thought Twitter adhered to the principle of free speech. Over 70% of respondents voted “no”.

An Ola Electric scooter caught fire while parked at the roadside in Pune, Maharashtra. In an unverified tweet posted on March 26, an Ola electric scooter could be seen in plumes of smoke, which ultimately led to the scooter catching fire. As per the tweet, it could be an Ola S1 or Ola S1 Pro scooter.

“We’re in constant touch with the customer who is absolutely safe,” said the startup. “Vehicle safety is of paramount importance at Ola and we are committed to the highest quality standards in our products. We take this incident seriously and will take appropriate action and share more in the coming days,” Ola said.

I have read about how you refuel an electric car is different. You don’t want to power an electric car on a power grid that uses fossil fuel. The goal is to have fully green refueling. I have theorized many things from my posts, such as using solar or wind with hydrogen storage. Also the components used to make batteries have an impact on the environment, unless I am wrong, as I can be wrong. I guess what I read must be wrong and Facebooks independent fact checkers are right. They always are right, and we must follow them. So please do.

Scientists astounded by performance of sustainable batteries with far-reaching implications for e-vehicles and devices.

Researchers at Bristol have developed high-performance sodium and potassium ion batteries using sustainably sourced cellulose.

Scientists at the Bristol Composites Institute have developed a novel controllable unidirectional ice-templating strategy which can tailor the electrochemical performances of next-generation post-lithium-ion batteries with sustainability and large-scale availability. The paper is published in the journal Advanced Functional Materials.

Starbucks is aiming to capitalize on the rising demand for electric vehicle infrastructure by installing fast chargers at up to 15 coffeehouses this summer, along a 1,350-mile route from Colorado to Washington.

The project, a pilot program with Volvo Cars, aims to build one DC charging station on each 100-mile segment of the western route.

Why install chargers at Starbucks? The coffeehouse chain is betting that it can score business from electric vehicle owners while they wait for their cars to charge — a process that can take a while, depending on the battery and strength of the charger.

USPS has been criticized for not ordering more EVs.


The United States Postal Service announced its initial order of 50,000 next-generation delivery vehicles, 10,019 of which will be battery-electric vehicles. It’s a notable number considering the agency’s resistance to calls for increasing the number of EVs in its future delivery fleet.

Originally, the postal service said it would purchase 165,000 next-generation mail trucks, only 10 percent of which will be battery-electric vehicles. President Joe Biden and congressional Democrats urged the agency to increase the number of EVs, but USPS determined there was no legal reason to change its plans.

Now, the postal service says it will increase its initial order of EVs from 5,000 to 10,019, determining it “makes good sense from an operational and financial perspective.”

Like electric vehicles – traditionally seen as expensive and niche – solar power is now becoming a realistic option for many households, as well as businesses wishing to decarbonise their operations. While the upfront costs of installing a photovoltaic (PV) rooftop system can be expensive, home solar will usually pay for itself within 5–10 years – and then provides the owner with an essentially free, limitless supply of clean energy, decentralised and unaffected by price volatility. Unlike the world’s increasingly scarce, finite supplies of coal, oil and gas, our Sun will continue to shine for another five billion years. Home solar can also be combined with batteries (which, like solar, are rapidly declining in cost) for energy storage at night.

At the utility scale, gigantic solar projects are now emerging in many countries. Recent years have seen the first gigawatt-scale (GW) facilities. The largest has a nameplate capacity of 2.3 GW. China is the world leader, accounting for 30% of all solar electric generation, followed by Europe (21%) and then the USA (16%). The vast majority is produced from PV modules, with a small fraction obtained by concentrated solar power (using mirrors or lenses to concentrate a large area of sunlight onto a receiver).

Following decades of rapid growth, the worldwide installed capacity of solar power has passed 1 TW this month, according to PV Magazine, an international trade publication headquartered in Berlin, Germany. The magazine has based its analysis on data from Bloomberg New Energy Finance (BNEF).
