Why South Koreans Are Rushing To Stockpile Sea Salt (independent.co.uk) 89

Long-time Slashdot reader beforewisdom shared this report from the Independent: South Koreans have begun to hoard excessive amounts of sea salt and other items as Japan prepares to dump treated radioactive water from the Fukushima power plant into the ocean... Tokyo has repeatedly assured that the water is safe and has been filtered to remove most isotopes though it does contain traces of tritium, an isotope of hydrogen hard to separate from water.

Although Japan has not set a date for the release, the announcement has made fishermen and shoppers across the region apprehensive. South Korea's fisheries authorities have vowed to ramp up efforts to monitor natural salt farms for any rise in radioactive substances and maintain a ban on seafood from the waters near Fukushima... The panic buying has led to a 27 per cent rise in the price of salt in South Korea in June from two months ago, though officials say the weather and lower production were also to blame. The Korean government in response has decided to release about 50 metric tons of salt a day from stocks, at a 20 per cent discount from market prices, until 11 July...

More than 85 per cent of the South Korean public oppose Japan's plan, according to a survey last month by local pollster Research View. Seven in 10 people reportedly said that they would consume less seafood if the waste water release goes ahead.

Is the Obsession with EV Range All Wrong? (msn.com) 613

"The obsession with EV range is all wrong," argues a new article in the Washington Post's Climate section. "This year, one EV on the market — the sleek $140,000 Lucid Air Grand Touring — boasts a whopping 516-mile range. Toyota recently announced that it had achieved a breakthrough with solid-state battery technology, saying it will soon be able to produce electric cars that can go 746 miles on a single charge.

"But some analysts say that all that range — and all that battery — misses the point, and wastes resources." Only 5% of trips in the U.S. are longer than 30 miles. The vast majority of big batteries will never be used — particularly if the owner has a place to plug in their car every day... Those batteries are massive, in every sense of the word: the battery on the electric F-150 Lightning, which allows the car to go more than 300 miles on a single charge, weighs a whopping 1,800 pounds.

But is all that necessary? Americans drive a lot, but most of our trips are not very long. According to data from the U.S. Department of Transportation, 95.1% of trips taken in personal vehicles are less than 31 miles; almost 60% of all trips are less than 6 miles. In total, the average U.S. driver only covers about 37 miles per day. And there is evidence that much smaller batteries could do the lion's share of the work. In a study published in 2016, researchers at MIT found that a car with a 73-mile range (like an early version of the Nissan Leaf), charged only at night, could satisfy 87% of all driving days in the United States. Providing Nissan Leafs to everyone whose driving fit that pattern, the researchers found, would cut 61% of U.S. gasoline consumption by personal vehicles...

So most of the time, drivers are lugging around giant batteries but only using 10 to 15% of their actual power. And those big batteries require mining a lot of metals, damaging the environment and workers' health... In a report by researchers at the University of California at Davis, the Climate and Community Project, and Providence College, experts found that simply switching to smaller EV batteries — batteries that could give a small car a range of 125 miles or so — could cut lithium demand by 42%...


The article notes that the upcoming Dodge Ram 1500 REV, with a range of about 500 miles, will need a battery "roughly equivalent in terms of resources to 16 batteries for the Prius Prime plug-in hybrid..."

"For those who need to take frequent long road trips and don't want to have to plug in, a plug-in hybrid can be a good option. But for most Americans, an EV with medium range will do just fine."

Nine AI-Powered Humanoid Robots Hold Press Conference at UN Summit (apnews.com) 30

We've just had the world's first press conference with AI-enabled, humanoid social robots. Click here to jump straight to Slashdot's transcript of all the robots' answers during the press conference, or watch the 40-minute video here.

It all happened as the United Nations held an "AI for Good" summit in Geneva, where the Guardian reports that the foyer was "humming with robotic voices, the whirring of automated wheels and limbs, and Desdemona, the 'rock star' humanoid, who is chanting 'the singularity will not be centralised' on stage backed by a human band, Jam Galaxy."

But the Associated Press describes how one UN agency had "assembled a group of robots that physically resembled humans at a news conference Friday, inviting reporters to ask them questions in an event meant to spark discussion about the future of artificial intelligence. "The nine robots were seated and posed upright along with some of the people who helped make them at a podium in a Geneva conference center... Among them: Sophia, the first robot innovation ambassador for the U.N. Development Program, or UNDP; Grace, described as a health care robot; and Desdemona, a rock star robot."

"I'm terrified by all of this," said one local newscaster, noting that the robots also said they "had no intention of rebelling against their creators."

But the Associated Press points out an important caveat: While the robots vocalized strong statements - that robots could be more efficient leaders than humans, but wouldn't take anyone's job away or stage a rebellion - organizers didn't specify to what extent the answers were scripted or programmed by people. The summit was meant to showcase "human-machine collaboration," and some of the robots are capable of producing preprogrammed responses, according to their documentation.
Two of the robots seemed to disagree on whether AI-powered robots should submit to stricter regulation. (Although since they're only synthesizing sentences from large-language models, can they really be said to "agree" or "disagree"?)

There were unintentionally humorous moments, starting right from the beginning. Click here to start reading Slashdot's transcript of the robots' answers:
