Toyota’s Solid-State, Lithium-Ion Batteries Increase Electric Car Range

(p. B6) TOKYO–Toyota Motor Corp. believes it has mastered the technology and production process for a new lithium-ion battery that could slash charging time and double the range of electric vehicles, according to U.S. patent filings and one of the inventors.
On Tuesday [July 25, 2017] Toyota said that by the early 2020s it planned to sell cars equipped with solid-state batteries, which replace the damp electrolyte used to transport lithium ions inside today’s batteries with a solid glass-like plate.
Behind Toyota’s brief statement lay years of research aimed at solving issues that have long bedeviled batteries for electric cars. Current lithium-ion batteries can’t be packed too tightly together because of fire risk. That is one reason electric cars tend to have limited range compared with traditional gasoline-powered cars.
With the solid-state battery, “you can improve the output and reduce the charge time–hopefully,” said Ryoji Kanno, a professor at the Tokyo Institute of Technology. Prof. Kanno led a team including Toyota scientists that discovered the materials for the glass-like electrolyte.

Workers Are Empowered, Not Threatened, by Robots

(p. A15) Most computer scientists agree that predictions about robots stealing jobs are greatly exaggerated. Rather than worrying about an impending Singularity, consider instead what we might call Multiplicity: diverse groups of people and machines working together to solve problems.
Multiplicity is not science fiction. A combination of machine learning, the wisdom of crowds, and cloud computing already underlies tasks Americans perform every day: searching for documents, filtering spam emails, translating between languages, finding news and movies, navigating maps, and organizing photos and videos.
Consider Google’s search engine. It runs on a set of algorithms with input from a large number of human users who share valuable feedback every time they click on or skip over a link. The same is true for spam filters. Every time someone marks an email as spam or overrides a filter, it helps fine-tune the system for determining what is relevant.
. . .
Multiplicity is collaborative instead of combative. Rather than discourage the human workers of the world, this new frontier has the potential to empower them.

Equal Opportunity Gene Innovation

(p. R4) Kian Sadeghi has postponed homework assignments, sports practice and all the other demands of being a 17-year-old high-school junior for today. On a Saturday afternoon, he is in a lab learning how to use Crispr-Cas9, a gene-editing technique that has electrified scientists around the world–. . .
. . .
Crispr-Cas9 is easier, faster and cheaper than previous gene-editing techniques.
. . .
A do-it-yourself Crispr kit with enough material to perform five experiments gene-editing the bacteria included in the package is available online for $150. Genspace, the Brooklyn, N.Y., community lab where Mr. Sadeghi is learning how to use Crispr to edit a gene in brewer’s yeast, charges $400 for four intensive sessions. More than 80 people have taken the classes since the lab started offering them last year.
. . .
In the workshop, if the participants correctly edit the gene in brewer’s yeast, the cells will turn red. In between the prep work, the classmates swap stories on why they are there. Many have personal Crispr projects in mind and want to learn the technique.
Kevin Wallenstein, a chemical engineer, takes a two-hour train ride to the lab from his home in Princeton, N.J. Crispr is a hobby for him, he says. He wants to eventually use it to edit a gene in an edible fruit that he prefers not to name, to restore it to its historical color. “I always wondered what it would look like,” he says.
At the workshop, Mr. Wallenstein shares his Crispr goal with Will Shindel, Genspace’s lab director. Mr. Shindel is enthusiastic; he has started his own Crispr project, a longtime dream to make a spicy tomato. Both men say they aren’t looking to commercialize their ideas–but they would like to eat what they create someday, if they get permission from the lab. “I’m doing it for fun,” Mr. Shindel says.
When Mr. Sadeghi first wanted to try Crispr, the teenager emailed 20 scientists asking if they would be willing to let him learn Crispr in their labs. Most didn’t respond; those that did turned him down. So he did a Google search and stumbled upon Genspace. When he shared the lead with his science teacher at the Berkeley Carroll School in Brooklyn, Essy Levy Sefchovich, she agreed to take the course with him.
When Mr. Shindel describes the steps of the experiment, Ms. Sefchovich takes notes. She is hoping to create a modified version of the yeast experiment so all her students can try Crispr in class.
Later, Mr. Sadeghi recounts that the hardest part of the day was handling the micropipette, the lab tool he used to mix small amounts of liquid. He says he still feels clumsy. Ms. Sefchovich reassures him he’ll get the hang of it; he just needs to practice.
“It’s like driving,” she tells him. “You learn the right feel.” Mr. Sadeghi doesn’t have his driver’s license yet. He figures he’ll do Crispr first.

Australian Government’s Centrally Planned “Costly Internet Bungle”

(p. A6) BRISBANE, Australia — Fed up with Australian internet speeds that trail those in most of the developed world, Morgan Jaffit turned to a more reliable method of data transfer: the postal system.
Hundreds of thousands of people from around the world have downloaded Hand of Fate, an action video game made by his studio in Brisbane, Defiant Development. But when Defiant worked with an audio designer in Melbourne, more than 1,000 miles away, Mr. Jaffit knew it would be quicker to send a hard drive by road than to upload the files, which could take several days.
“It’s really the big file sizes that kill us,” said Mr. Jaffit, the company’s co-founder and creative director. “When we release an update and there’s a small bug, that can kill us by three or four days.”
Australia, a wealthy nation with a widely envied quality of life, lags in one essential area of modern life: its internet speed. Eight years after the country began an unprecedented broadband modernization effort that will cost at least 49 billion Australian dollars, or $36 billion, its average internet speed lags that of the United States, most of Western Europe, Japan and South Korea. In the most recent ranking of internet speeds by Akamai, a networking company, Australia came in at an embarrassing No. 51, trailing developing economies like Thailand and Kenya.
. . .
The story of Australia’s costly internet bungle illustrates the hazards of mingling telecommunication infrastructure with the impatience of modern politics. The internet modernization plan has been hobbled by cost overruns, partisan maneuvering and a major technical compromise that put 19th-century technology between the country’s 21st-century digital backbone and many of its homes and businesses.
The government-led push to modernize its telecommunications system was unprecedented, experts say — and provides a cautionary tale for others who might like to try something similar.
“Australia was the first country where a totally national plan to cover every house or business was considered,” said Rod Tucker, a University of Melbourne professor and a member of the expert panel that advised on the effort.

94-Year-Old Applies for Patent on Slow-Hunch Solid State Battery

(p. 7) In 1946, a 23-year-old Army veteran named John Goodenough headed to the University of Chicago with a dream of studying physics. When he arrived, a professor warned him that he was already too old to succeed in the field.
Recently, Dr. Goodenough recounted that story for me and then laughed uproariously. He ignored the professor’s advice and today, at 94, has just set the tech industry abuzz with his blazing creativity. He and his team at the University of Texas at Austin filed a patent application on a new kind of battery that, if it works as promised, would be so cheap, lightweight and safe that it would revolutionize electric cars and kill off petroleum-fueled vehicles. His announcement has caused a stir, in part, because Dr. Goodenough has done it before. In 1980, at age 57, he coinvented the lithium-ion battery that shrank power into a tiny package.
We tend to assume that creativity wanes with age. But Dr. Goodenough’s story suggests that some people actually become more creative as they grow older. Unfortunately, those late-blooming geniuses have to contend with powerful biases against them.
. . .
Years ago, he decided to create a solid battery that would be safer. Of course, in a perfect world, the “solid-state” battery would also be low-cost and lightweight. Then, two years ago, he discovered the work of Maria Helena Braga, a Portuguese physicist who, with the help of a colleague, had created a kind of glass that can replace liquid electrolytes inside batteries.
Dr. Goodenough persuaded Dr. Braga to move to Austin and join his lab. “We did some experiments to make sure the glass was dry. Then we were off to the races,” he said.
Some of his colleagues were dubious that he could pull it off. But Dr. Goodenough was not dissuaded. “I’m old enough to know you can’t close your mind to new ideas. You have to test out every possibility if you want something new.”
When I asked him about his late-life success, he said: “Some of us are turtles; we crawl and struggle along, and we haven’t maybe figured it out by the time we’re 30. But the turtles have to keep on walking.” This crawl through life can be advantageous, he pointed out, particularly if you meander around through different fields, picking up clues as you go along. Dr. Goodenough started in physics and hopped sideways into chemistry and materials science, while also keeping his eye on the social and political trends that could drive a green economy. “You have to draw on a fair amount of experience in order to be able to put ideas together,” he said.

Self-Driving Cars Would Help Older Adults Continue to Live at Home

(p. B4) Single, childless and 68, Steven Gold has begun to think about future mobility and independence. Although in good health, he can foresee a time when he won’t be a confident driver, if he can drive at all. While he hopes to continue to live in his suburban Detroit home, he wonders how he will be able to get to places like his doctor’s office and the supermarket if his driving becomes impaired.
For Mr. Gold and other older adults, self-driving cars might be a solution.
The number of United States residents age 70 and older is projected to increase to 53.7 million in 2030, from 30.9 million in 2014, according to the Institute for Highway Safety. Nearly 16 million people 65 and older live in communities where public transportation is poor or nonexistent. That number is expected to grow rapidly as baby boomers remain outside of cities.
“The aging of the population converging with autonomous vehicles might close the coming mobility gap for an aging society,” said Joseph Coughlin, the director of the Massachusetts Institute for Technology AgeLab in Cambridge.
He said that 70 percent of those over age 50 live in the suburbs, a figure he expects to remain steady despite a recent rise in moves to urban centers. Further, 92 percent of older people want to age in place, he said.

“Mind-Bending” Automatic Braking Trickles Down to Cheaper Cars

(p. B4) I first experienced radar-assisted cruise control in a $70,000 Mercedes in 2001. Slowing automatically to keep from hitting the car ahead felt like a magic trick. In 2009, I was told to drive a new $50,000 Volvo into the back of a “parked car” (really, an inflatable mock-up). Every fiber of my body wanted to stomp on the brake pedal. Instead, the car did it for me. Automatic braking is mind-bending the first time.
Both of these technologies are standard equipment on 2017 Toyota Corollas, which start at $19,385. So is lane-keeping assist, which nudges the car back between the road stripes if you wander. Automatic high-beam headlamps, too.
Huzzah for technology trickle down!

Amateur Tinkerers Keep Steam Power Alive

(p. D4) Most people, when they think of steam power, they think of rusty farm tractors from 150 years ago. But there’s such a thing as modern steam power. Steam is the most direct way to get power out of heat. You can’t build an internal combustion engine in your garage. But you can build a steam engine, and the interesting thing is, it can run on anything that will burn, even sawdust.
At my farm, I have about 100 steam engines, many of them homemade, plus a library of technical papers, patents, and books on steam technology. I have Volkswagen engines converted to steam, outboard boat engines, etc. I collect and preserve this stuff. I get a lot of it from old widows whose deceased husbands were tinkerers; these women are so happy to get rid of it. Some of the engines are well built, others not, but you can learn as much from a bad example as a good one.

Nano-Enhanced Fabrics Can Clean Themselves

(p. D3) Scientists in Australia, one of the sunniest places on the planet, have discovered a way to rid clothes of stubborn stains by exposing them to sunlight, potentially replacing doing the laundry.
Working in a laboratory, the researchers embedded minute flecks of silver and copper–invisible to the naked eye–within cotton fabric. When exposed to light, the tiny metal particles, or nanostructures, released bursts of energy that degraded any organic matter on the fabric in as little as six minutes, said Rajesh Ramanathan, a postdoctoral fellow at RMIT University, in Melbourne.
The development, reported recently in the journal Advanced Materials Interfaces, represents an early stage of research into nano-enhanced fabrics that have the ability to clean themselves, Dr. Ramanathan said. The tiny metal particles don’t change the look or feel of the fabric. They also stay on the surface of the garment even when it is rinsed in water, meaning they can be used over and over on new grime, he said.

“Slow Is Smooth and Smooth Is Fast”

(p. B2) WASHINGTON — Jeff Bezos, the billionaire chief executive of Amazon, founded a rocket company as a hobby 16 years ago. Now that company, Blue Origin, finally has its first paying customer as it ramps up to become a full-fledged business.
Mr. Bezos announced that customer, the satellite television provider Eutelsat, on Tuesday. In about five years, Eutelsat, which is based in Paris, will strap one of its satellites to a new Blue Origin rocket to be delivered to space, a process it has done dozens of times with other space partners.
. . .
Blue Origin’s deal with Eutelsat is a “definite statement to the industry that Blue Origin will be a viable commercial launch vehicle,” said Carissa Bryce Christensen, the chief executive of Bryce Space and Technology, a consulting firm.
. . .
Mr. Bezos “is investing because he wants to transform people’s lives with space capabilities, but the expectation has always been that this will be a successful business,” Ms. Christensen said.
. . .
Mr. Bezos said he was approaching his space project with an abundance of patience.
“I like to do things incrementally,” he said, noting that Blue Origin’s mascot is a tortoise. With such high costs and risks with each rocket launch, it is important not to skip steps, he said.
“Slow is smooth and smooth is fast,” said Mr. Bezos, who also owns The Washington Post and a clock that will keep time for 10,000 years. “I’ve seen this in every endeavor I’ve been in.”

For $9,000, No Chicken Need Die, When You Eat a Pound of Chicken

(p. B3) A Bay Area food-technology startup says it has created the world’s first chicken strips grown from self-reproducing cells without so much as ruffling a feather.
And the product pretty much tastes like chicken, according to people who were offered samples Tuesday [March 14, 2017] in San Francisco, before Memphis Meats Inc.’s formal unveiling on Wednesday.
Scientists, startups and animal-welfare activists believe the new product could help to revolutionize the roughly $200 billion U.S. meat industry. Their goal: Replace billions of cattle, hogs and chickens with animal meat they say can be grown more efficiently and humanely in stainless-steel bioreactor tanks.
. . .
On Tuesday [March 14, 2017], Memphis Meats invited a handful of taste-testers to a San Francisco kitchen and cooked and served their chicken strip, along with a piece of duck prepared à l’orange style.
Some who sampled the strip–breaded, deep-fried and spongier than a whole chicken breast–said it nearly nailed the flavor of the traditional variety. Their verdict: They would eat it again.
. . .
The cell-cultured meat startups are a long way from replacing the meat industry’s global network of hatcheries, chicken barns, feed mills and processing plants. But they say they’re making progress. Memphis Meats estimates its current technology can yield one pound of chicken meat for less than $9,000. That is half of what it cost the company to produce its beef meatball about a year ago. The startups, however, aspire to produce meat that can be cost-competitive with the conventionally raised kind.
