Tesla 4680 production hits milestone of 868k cells in seven days

Posted by in categories: sustainability, transportation

It appears that Tesla’s 4,680 battery cell production line is hitting its rhythm. As recently announced by the company, its 4,680 team has managed to build 868,000 cells in the last seven days. That’s roughly equal to the battery packs of over 1,000 electric vehicles.

Tesla announced the milestone on its official Twitter account. The EV maker highlighted its appreciation for its 4,680 team in its post, while also including a couple of photos of the teams behind the milestone. “Congrats to the 4,680 cell team on achieving 868k cells built in the last 7 days—equal to 1k+ cars!” Tesla wrote.

While producing enough cells for over 1,000 electric cars may seem like a minor achievement considering the scale of Tesla’s overall operations, the accomplishment was likely achieved with just the company’s initial 4,680 production lines. Tesla currently produces 4,680 cells in its pilot line at Kato Road, close to the Fremont Factory. Giga Texas also has a 4,680 line.

New Technology Could Tap Into a Virtually Limitless Supply of Fresh Water

Posted by in category: sustainability

There’s not enough fresh water to go around on planet Earth, and it’s a problem that’s expected to only worsen in the coming years.

To meet growing demand, recycling and restricting our water will only get us so far. Scientists will need to find new sources of this life-sustaining liquid to meet our needs.

One currently untapped source is the water vapor above the oceans, which is almost limitless as far as supplies go. A new study outlines how harvesting structures could be used to convert this vapor into drinkable water.

Polar bear population dwindling at alarming rate in Canada: Report

Posted by in categories: climatology, government, sustainability

A new survey conducted by the Canadian government has found that polar bears in the country’s Western Hudson Bay, are dying at alarming rates. The researchers aerially surveyed the Bay and its nearby town of Churchill also referred to as the ‘Bear capital of the World’ in 2021 and found there were 618 bears only, compared to 842, five years ago when last counted.

The survey added that a significant decline has been noted in the population of adult female bears and cubs between 2011 and 2021.

“The observed declines are consistent with long-standing predictions regarding the demographic effects of climate change on polar bears,” said the researchers.

EPFL

According to a report by Euronews, researchers at the École Polytechnique Fédérale de Lausanne (EPFL) have discovered a way to create transparent photosensitizers, molecules that can be activated by light and adsorb light across the entire visible light spectrum. Previous versions of DSCs were largely dependent on direct sunlight.

Celebrating Energy Central’s Top Voices in the Community for 2022 — Energy & Sustainability Network

Posted by in categories: energy, sustainability

As our Energy Central Community thrives and grows with each passing year, it’s clear to us that we have something special here. This community of power industry professionals who so eagerly and openly share their insights, their lessons learned, and their questions to allow for constant collaboration is unparalleled anywhere else in our sector.

The most critical part of this successful undertaking, though, is of course the people behind it all. The voices in our Community who are driving those conversations and keeping readers and peers coming back again and again. To once again celebrate the importance of our community members in making Energy Central the powerhouse that it is, we’re ending the year by honoring the members on Energy Central who went above and beyond—frequently sharing news and content, reliably starting conversations across the site, and providing some of the most genuinely high-value contributions throughout 2022.

All week, we’ll be publishing articles highlighting the Top Voice of 2022 for each of our 6 Networks. As part of this tradition, some of those community members recognized were kind enough to answer a few questions to highlight what they found valuable in the sector in 2022, their predictions for 2023, and some personal insights to get to know the men and women behind it all.
