Taking public transportation in San Francisco is going to get even greener

You’re already reducing your carbon footprint by taking public transportation. Now the system itself is reducing its own carbon footprint. That is, if that public transportation is located in San Francisco.

The California city’s BART (Bay Area Rapid Transit) system has adopted “aggressive guidelines” enabling it to buy more power directly from renewable sources. Thanks to the newly approved Wholesale Electricity Portfolio Policy, the BART is going greener than ever.

“Every day, BART takes cars off the road and helps drive down our greenhouse gas emissions,” said BART Director Nick Josefowitz. “But especially now, BART and the Bay Area must shoulder even more responsibility to combat climate change. Even though BART is not required to comply with the state’s renewable energy standards, we have committed to purchasing 100 percent renewable electricity and taking a leadership role in decarbonizing our transportation sector.”

While BART already boasts a relatively clean portfolio in terms of its power sources, its newfound ability to buy its own power from various renewable energy sources including solar, wind, and small hydroelectric facilities, will make the transport system more environmentally friendly still. The hope is that the BART will derive its power from at least 50 percent eligible renewable sources and from at least 90 percent low and zero carbon sources by 2025. And a few more decades down the road, BART hopes to hit 100 percent in both these categories.

“Given that renewable energy supply costs have fallen significantly in recent years and have approached cost parity with other supply sources, BART has an opportunity to set clean energy goals that are both ambitious and realistic,” said BART’s Sustainability Manager Holly Gordon.

Thus far, BART seems like it’s the very first electrified public transit system to make the 100 percent renewable power pledge. And hopefully, it’ll set a precedent that transport agencies across the country (and the world) can emulate.

San Francisco won the battle, but the war on facial-recognition has just begun

could ai based surveillance predict crime before it happens us technology artificial intelligence

San Francisco has become the first city in America to ban facial recognition. Well, kind of.

In fact, the ban -- voted on this week by the city’s Board of Supervisors -- bars only the use of facial recognition by city agencies, such as the police department. It doesn’t affect the use of facial recognition technology in locations like airports or ports, for example, or from private applications orchestrated by private companies. Oh yes, and because the San Francisco police department doesn’t currently use facial recognition technology, this ruling bans something that wasn’t actually being used. While the department tested the technology on booking photos between 2013 and 2017, it has not implemented this use-case on a permanent basis.

Digital Trends’ Tech For Change CES 2023 Awards

Digital Trends CES 2023 Tech For Change Award Winners Feature

CES is more than just a neon-drenched show-and-tell session for the world’s biggest tech manufacturers. More and more, it’s also a place where companies showcase innovations that could truly make the world a better place — and at CES 2023, this type of tech was on full display. We saw everything from accessibility-minded PS5 controllers to pedal-powered smart desks. But of all the amazing innovations on display this year, these three impressed us the most:

Samsung's Relumino Mode
Across the globe, roughly 300 million people suffer from moderate to severe vision loss, and generally speaking, most TVs don’t take that into account. So in an effort to make television more accessible and enjoyable for those millions of people suffering from impaired vision, Samsung is adding a new picture mode to many of its new TVs.

Relumino Mode, as it’s called, works by adding a bunch of different visual filters to the picture simultaneously. Outlines of people and objects on screen are highlighted, the contrast and brightness of the overall picture are cranked up, and extra sharpness is applied to everything. The resulting video would likely look strange to people with normal vision, but for folks with low vision, it should look clearer and closer to "normal" than it otherwise would.
Excitingly, since Relumino Mode is ultimately just a clever software trick, this technology could theoretically be pushed out via a software update and installed on millions of existing Samsung TVs -- not just new and recently purchased ones.

AI turned Breaking Bad into an anime — and it’s terrifying

Split image of Breaking Bad anime characters.

These days, it seems like there's nothing AI programs can't do. Thanks to advancements in artificial intelligence, deepfakes have done digital "face-offs" with Hollywood celebrities in films and TV shows, VFX artists can de-age actors almost instantly, and ChatGPT has learned how to write big-budget screenplays in the blink of an eye. Pretty soon, AI will probably decide who wins at the Oscars.

Within the past year, AI has also been used to generate beautiful works of art in seconds, creating a viral new trend and causing a boon for fan artists everywhere. TikTok user @cyborgism recently broke the internet by posting a clip featuring many AI-generated pictures of Breaking Bad. The theme here is that the characters are depicted as anime characters straight out of the 1980s, and the result is concerning to say the least. Depending on your viewpoint, Breaking Bad AI (my unofficial name for it) shows how technology can either threaten the integrity of original works of art or nurture artistic expression.
What if AI created Breaking Bad as a 1980s anime?
Playing over Metro Boomin's rap remix of the famous "I am the one who knocks" monologue, the video features images of the cast that range from shockingly realistic to full-on exaggerated. The clip currently has over 65,000 likes on TikTok alone, and many other users have shared their thoughts on the art. One user wrote, "Regardless of the repercussions on the entertainment industry, I can't wait for AI to be advanced enough to animate the whole show like this."
