Tesla warns against wet towel charging trick two months too late

Posted on by

Tesla car culture is full of hacks and shortcuts, some more effective than others. One, known as the “wet towel” trick, required the Tesla Charging department — or whatever remains of it — to publicly tell customers to knock it off.

The “wet towel” trick involves wrapping a damp, cool cloth around a Supercharger cable handle as a way to presumably speed up the charging time. The Supercharger has temperature monitors that keep it from overheating as it charges Tesla vehicles. Some Tesla owners believe that cooling down the charging handle will trick the temperature monitor into topping off their vehicles faster.

Here's the problem, at least in Tesla's telling: If the sensor in the charging handle believes that the temperature is lower than it actually is while it’s charging, the towel-wrapped charger can create a "risk of overheating or damage" according to the company.

This may sound like the biggest “duh” statement in tech news history but it’s taken more than two months for Tesla to warn its customers not to do the “wet towel” trick on their cars, even after it became a well known “hack” on other auto news websites and Reddit forums. The official Tesla Charging account on X posted a warning on Wednesday in response to an article from InsideEVs.com explaining the dangerous car charging trick.

This kind of epic communication breakdown is what happens when a major automaker doesn’t have a public relations department. Tesla dissolved its entire PR team in 2020 and Elon Musk publicly refused to hire one on his X account the following year saying he didn’t want to “spend money on advertising & manipulating public opinion,” according to Electrek.

Rivian opens its first Charging Outpost, a crunchy not-gas station near Yosemite

Posted on by

Rivian just opened its first EV charging rest stop 24 miles outside of Yosemite National Park, complete with bathrooms, a lounge with a small library, a water refill station, free coffee and (not free) “make your own” trail mix. Only Rivian owners will be able to make use of the five DC fast chargers at the Rivian Yosemite Charging Outpost, but the other amenities are open to anyone.

The Charging Outpost is located in Groveland, California near the park’s west entrance and takes the place of an abandoned gas station. The shop area will be open from 7AM to 7PM, while the bathrooms and chargers will be available 24/7. It’s the first time Rivian has ventured into this kind of infrastructure, building on its growing network of regular charging sites — several of which are situated near Yosemite. The EV maker has 58 Waypoint charging sites, which support any electric vehicle that uses the standard J1772 plug, around the Yosemite Valley, and a Rivian-only Adventure charging site near the park’s east entrance.

Rivian says it has plans for more Charging Outposts “around national parks and other high-traffic areas across the country.” The first such building was designed with the intention of keeping waste to a minimum, and its retaining wall was made using materials from the old parking lot and sidewalk. It’s fitted with solar panels and has a passive cooling design that’s meant to reduce the need for AC or heating.

Beyond Charging Outposts, Rivian plans to eventually have over 3,500 of its Adventure Network DC fast chargers available in 600 sites across the US and Canada, on top of roughly 10,000 Level 2 chargers that will be open to the public.

Environmental groups accuse Amazon of ‘distorting the truth’ in latest clean-energy claim

Posted on by

On Wednesday, Amazon claimed that it reached its goal of sourcing all its power from clean energy sources in the past year. If taken at face value, the announcement would mean it hit the milestone seven years ahead of schedule, which would be a monumental achievement. But environmental experts speaking to The New York Times, including a group of concerned Amazon employees, warn that the company is “misleading the public by distorting the truth.”

The company’s claim of achieving 100 percent clean electricity is based in part on billion-dollar investments in over 500 solar and wind initiatives. The company’s logic is that the energy these projects generate equals the electricity its data centers consume — ergo, even Steven.

But the renewable energy sources it uses for those calculations are fed into a general power grid, not exclusively into Amazon’s operations. Environmental experts caution that the company is using “accounting and marketing to make itself look good,” as The New York Times put it.

“Amazon wants us to think of its data centers as surrounded by wind and solar farms,” the group Amazon Employees for Climate Justice wrote in a statement to The NYT. “[But] the reality is the company is heavily investing in data center expansions fueled by West Virginian coal, Saudi Arabian oil and Canadian fracked gas.”

Clean energy experts say Amazon’s inclusion of renewable energy certificates (RECs) in its calculations can be highly misleading. This is because if any power plants on a grid burn fossil fuels, businesses can’t know that the grid uses only clean energy. The Amazon employee group told The New York Times that, after subtracting the company’s use of RECs in its calculations, its clean-energy investment was “just a fraction of what was publicized.”

“Buying a bunch of RECs doesn’t help anything,” Leah Stokes, associate professor of environmental politics at UC Santa Barbara, told The NYT. “You just have to be investing in real projects.”

To be fair, any movement toward clean energy should be applauded. Amazon still received a “B” grade from the nonprofit CDP (formerly the Carbon Disclosure Project), which was lower than Google and Microsoft’s “A” but still a passing grade. The problem comes when companies use the smoke and mirrors more often associated with marketing and PR to mislead the public into believing they’re doing more for the environment than they are.

“A company needs to actually outline, what are the sources that you are accounting for in that calculation?” Simon Fischweicher, a CDP director, told The NYT.

With the meteoric rise of AI and the financial pressures to compete in this new gold rush, companies are now reshuffling their decks and finding new ways to meet their climate goals. However, if that shakeup offers less tangible movement and more weasel words and sketchy logic, then that’s creating a new problem on top of their alleged solutions for a genuine crisis.

Google’s greenhouse gas emissions climbed nearly 50 percent in five years due to AI

Posted on by

Google’s greenhouse gas emissions spiked by nearly 50 percent in the last five years thanks to energy-guzzling data centers required to power artificial intelligence, according to the company’s 2024 Environmental Report released on Tuesday. The report, which Google releases annually, shows the company’s progress towards meeting its self-proclaimed objective of becoming carbon neutral by 2030.

Google released 14.3 million metric tons of carbon dioxide in 2023, the report states, which was 48 percent higher than in 2019, and 13 percent higher than a year before. “This result is primarily due to increases in data center energy consumption and supply chain emissions,” said Google in the report. “As we further integrate AI into our products, reducing emissions may be challenging due to increasing energy demands associated with the expected increases in our technical infrastructure investment.”

Google’s report spotlights the environmental impact that the explosion of artificial intelligence has had on the planet. Google, Microsoft, Amazon, Meta, Apple and other tech companies plan to pour billions of dollars into AI, but training AI models requires enormous amounts of energy. Using AI features uses significant amounts of energy too. In 2023, researchers at AI startup Hugging Face and Carnegie Mellon University found that generating a single image using artificial intelligence can use as much energy as charging a smartphone. Analysts at Bernstein said that AI would “double the rate of US electricity demand growth and total consumption could outstrip current supply in the next two years,” the Financial Times reported. Last month, Microsoft, which also pledged to go “carbon negative” by the end of this decade, reported that its greenhouse gas emissions had risen nearly 30 percent since 2020 due to the construction of data centers.

Google’s report said that the company’s data centers were using way more water than before to stay cool as a result of expanded AI workloads. Some of those workloads so far have involved Google Search suggesting that people eat rocks and put glue on their pizza to prevent the cheese from falling off, as well as Gemini, the company’s AI-powered chatbot, generating images of ethnically diverse Nazis.

In 2023, Google’s data centers consumed 17 percent more water than the year before. That’s 6.1 billion liters, enough to irrigate approximately 41 golf courses annually in the southwestern United States, according to the company’s strangely kooky measure.

“As our business and industry continue to evolve, we expect our total GHG (greenhouse gas) emissions to rise before dropping toward our absolute emissions reduction target,” Google’s report stated, without explaining what would precipitate the drop. “Predicting the future environmental impact of AI is complex and evolving, and our historical trends likely don’t fully capture AI’s future trajectory. As we deeply integrate AI across our product portfolio, the distinction between AI and other workloads will not be meaningful.”

Google invests in Taiwanese solar company to boost green energy

Posted on by

Google is investing in a Taiwanese solar company with plans to build a 1 gigawatt (GW) pipeline of sustainable energy in the region. The company is placing a stake in New Green Power (NGP), part of BlackRock’s investment portfolio, for the project. The move could help Google and Taiwan move closer to their climate goals while stabilizing green energy production in one of the most crucial semiconductor hubs of our new AI-infused world.

Google already has a significant presence in Taiwan, including a data center. According to Amanda Peterson Corio, Google’s global head of data center energy, fossil fuels currently generate nearly 85 percent of Taiwan’s power grid. “To help overcome these obstacles, companies can play a pivotal role in finding new strategies to grow the supply of available renewable energy sources and promoting emerging technologies that enable the full decarbonization of regional electricity systems,” she wrote.

Google expects to use up to 300 megawatts of solar capacity to power its data centers in Taiwan. In addition, Peterson Corio says the company “may offer a portion of this clean energy capacity to [its] semiconductor suppliers and manufacturers in the region.” She said that would help its partners meet their green energy goals and reduce indirect (Scope 3) emissions from Google’s supply chain partners.

“A significant share of our Scope 3 footprint can be traced back to the electricity grids that power our suppliers and users, which is why broad decarbonization — and partnerships like this — continue to be core to our net-zero goal,” Peterson Corio wrote.

Regulators haven’t yet approved the deal. Google hasn’t said how much it’s investing in NGP.

China is plowing $11 billion into a solar, wind and coal energy project

Posted on by

A Chinese state-owned power company is splashing out 80 billion yuan ($11 billion) on an energy base that will generate electricity from solar, wind and coal sources. China Three Gorges Renewables Group, a subsidiary of the country’s largest hydropower company, plans to build a plant with a 16-gigawatt capacity and a five-gigawatt storage facility, Bloomberg reports.

This is part of China’s aim to build 455 gigawatts worth of renewable energy projects in the desert by 2030. This plant is being constructed in Inner Mongolia, which will get 135 gigawatts of the total planned output.

The China Three Gorges Corporation is looking to diversify its energy sources as building large hydro dams is becoming less feasible. According to Three Gorges, wind and solar generation from the plant will depend on grid accessibility. The coal plant is set to start operations in three years.

It’s somewhat disappointing that the new plant will have a coal power element, though it's not fully surprising given the way China has bristled at renewable energy commitments during climate summit talks with other countries. As Bloomberg notes, China has been struggling to put all of its clean energy into the power grid. It often relies on coal when renewable sources like solar and wind aren’t available.

Amazon says it’s cut down on those plastic air pillows in packages

Posted on by

You know those little plastic air bags in your more fragile Amazon purchases that make perfect popping noise makers when you crush them? Amazon says it's reduced its usage of them and plans to completely eliminate using them by the end of the year.

The ecommerce behemoth announced on its news blog that it has reduced the use of plastic air pillows by 95 percent and switched to crumbled paper filler instead. Amazon also says it plans to use paper filler for “nearly all” of its customer deliveries on Prime Day.

The company says its decision to phase out the use of plastic air cushions at its distribution centers aims to eliminate unnecessary waste and focus more on using recycled materials.

Plastic pollution has always been a concern when it comes to our environment but it has dramatically increased as a result of Amazon’s meteoric rise especially during the COVID pandemic. The nonprofit ocean conservation group Oceana released a study in 2021 showing that Amazon produced 599 million pounds of plastic waste in 2020. The group also estimated that the waste produced from plastic air pillows alone “would circle the Earth more than 600 times.”

Tesla shareholders have approved Elon Musk’s ‘unfathomable’ pay package

Posted on by

Tesla shareholders have again approved Elon Musk’s multi-billion dollar pay package several months after a Delaware court invalidated it. During the electric car maker’s annual shareholder meeting, the company's stockholders signed off on a proposal to reinstate Musk’s pay package, currently worth about $48 billion, according to Bloomberg.

Judge Kathaleen McCormick of Delaware’s Chancery Court previously called the Tesla CEO’s pay, worth $56 billion when it was first approved in 2018, an "unfathomable sum.” Musk responded by threatening to move the company’s state of incorporation to Texas. During Tesla’s meeting, shareholders officially signed off on the move.

The approval of Musk’s compensation doesn’t guarantee that his eye-popping pay will be reinstated. As Bloomberg points out, the vote doesn't invalidate the judge's initial ruling, but Tesla will almost certainly appeal and point to the latest shareholder vote as evidence that the company’s stockholders have approved it.

Unsurprisingly, Musk seemed pleased with the vote. “I just want to start off by saying, hot damn. I love you guys,” he said after taking the stage at the shareholder meeting. He later said that the reinstatement of his pay wouldn’t affect his short-term commitment to Tesla. “It is worth emphasizing that it’s Tesla stock that I have to own for five years. It's not actually cash, and I can't cut and run, nor would I want to.”

New research places the sun’s magnetic field close to the surface, upending decades of theories

Posted on by

New research indicates the sun’s magnetic field originates close to the surface and not deep within the star, according to findings published in the journal Nature. This upends decades of prevailing scientific thought that placed the field more than 130,000 miles below the surface of the sun. It also brings us closer to understanding the nature of the sun’s magnetic field, which has been on scientist’s minds since Galileo.

The study, led by Northwestern University and a team of international researchers, suggests that the magnetic field actually generates 20,000 miles below the surface. This was discovered after the team ran a series of complex calculations on a NASA supercomputer. It’s worth noting that these are just initial findings and more research is required to confirm the data.

The sun’s magnetic field fluctuates in a cycle that lasts 11 years. During the strongest part of this cycle, powerful winds and sunspots form at the solar equator, along with plumes of material that cause the aurora borealis here on Earth. Previous theories that place the magnetic field deeper within the sun have had a difficult time connecting these various solar phenomena. Scientists hope that, given further study, they’ll be able to use this theory to not only explain the creation of solar events, but more accurately predict when they will occur.

This could lead to more than just earlier predictions of the next aurora borealis event. The sun’s intense magnetic energy is also the source of solar flares and eruptions of plasma called coronal mass ejections. When these ejections travel toward Earth, all kinds of bad things happen. This famously occurred back in 1859, when a giant geomagnetic storm created the largest solar storm in recorded history.

This is called the Carrington Event, attributed to British astronomer Richard Christopher Carrington. The solar flare, which was actually a magnetic explosion on the sun’s surface, briefly outshone the sun and caused colored lights to erupt all over the planet, similar to the aurora borealis. It also supercharged telegraph cables, shocking operators, and set telegraph paper on fire. It was pretty nasty.

Now, this was 1859, before the modern use of electricity and before computers and all related technologies. If something like the Carrington Event were to occur today, we’d have it much worse. The emitted X-rays and ultraviolet light would interfere with electronics, radio and satellite signals. The event would cause a solar radiation storm, which would be deadly to astronauts not fully equipped with protective gear.

It would also lead a coronal mass ejection to bump up against Earth’s magnetic field, which would shut down power grids, cell phone satellites, modern cars and even airplanes. The resulting global power outages could last for months. Last month’s smallish (relatively speaking) storm messed with electronics and that was no Carrington-sized event. Even worse? We are absolutely due for this to happen. It’s basically a ticking time bomb.

So these findings could, in theory, be used to prepare new early warning methods for large-scale solar flares hitting Earth. Someday, we might have solar flare warnings alongside hurricane warnings and the like. The research has already demonstrated some interesting links between sunspots and the sun’s magnetic activity.

“We still don’t understand the sun well enough to make accurate predictions” of solar weather, lead study author Geoffrey Vasil of the University of Edinburgh told The Hill. These new findings “will be an important step toward finally resolving” this mysterious process, added co-author Daniel Lecoanet of Northwestern University.
