Let’s say you’ve gone and bought a high-definition LCD TV that’s as big as your outstretched arms. And perhaps you’ve also splurged on a 7.1 channel surround sound system, and an upconverting DVD player or maybe a sleek Blu-ray player. Maybe you’ve got a state-of-the-art game console or Apple TV or some other Web-based feed. Well, come 17 February, you just might want one more thing: a new antenna on your roof.

If you live in the United States and you’re one of the 19 million people who still prefer to pull their TV signals out of the air rather than pay a cable company to deliver them, you may already know that this month the vast majority of analog television broadcasts in the United States are scheduled to end and most free, over-the-air TV signals will be transmitted only in the new digital Advanced Television Systems Committee (ATSC) format. A massive advertising campaign is now telling people who get their signals from the ether that they’ll need a TV with a built-in ATSC tuner or a digital converter box to display their favorite programs.

Tesla’s Autopilot Depends on a Deluge of Data

But can a fire-hose approach solve self-driving’s biggest problems?

In 2019, Elon Musk stood up at a Tesla day devoted to automated driving and said, “Essentially everyone’s training the network all the time, is what it amounts to. Whether Autopilot’s on or off, the network is being trained.”

Tesla’s suite of assistive and semi-autonomous technologies, collectively known as Autopilot, is among the most widely deployed—and undeniably the most controversial—driver-assistance systems on the road today. While many drivers love it, using it for a combined total of more than 5 billion kilometers, the technology has been involved in hundreds of crashes, some of them fatal, and is currently the subject of a comprehensive investigation by the National Highway Traffic Safety Administration.

Wind turbines generate electricity at the Block Island Wind Farm on 7 July 2022 near Block Island, Rhode Island. The five-turbine, 30-megawatt project was developed by Deepwater Wind and began operations in December 2016 at a cost of nearly $300 million.

Early in July, Rhode Island’s governor signed legislation mandating that the state acquire 100 percent of its electricity from renewable sources by 2033. Among the state’s American peers, there’s no deadline more ambitious.

“Anything more ambitious, and I would start being a little skeptical that it would be attainable,” says Seaver Wang, a climate and energy researcher at the Breakthrough Institute.
