Japanese inventor’s typhoon turbines harness storms’ energy

A Japanese engineer named Atsushi Shimizu has designed a new type of wind turbine that can harness energy from something more powerful than a strong breeze. Shimizu’s creation, which looks like a huge, upright egg beater, can withstand typhoons (or hurricanes, depending on where you live) and turn their destructive power into usable energy. Unlike ordinary turbines, it can stay standing even when assaulted by intense winds and rain, thanks to an omnidirectional vertical axis and blades with adjustable speeds. That makes them perfect for their creator’s home country, as well as other places frequently visited by storms, such as China, the Philippines and the US.

Shimizu says the energy from a single typhoon can power Japan for 50 years, and with the help of his turbines, the country could become a "super power of wind." Even if his creation can capture all that energy, though, it will likely be tough finding a way to store 50 years’ worth of power at this point in time. We might not have the battery tech capable of that just yet. Shimizu’s company installed a prototype earlier this year in Okinawa, and it’s now gunning to build one either on the Tokyo Tower or at Japan’s National Stadium, where the Olympics will be held in 2020.

Here comes 5Gbps networking over standard cables

A new Ethernet standard that allows for up to 2.5Gbps over normal Cat 5e cables (the ones you probably have in your house) has been approved by the IEEE. The standard—formally known as IEEE 802.3bz-2016, 2.5G/5GBASE-T, or just 2.5 and 5 Gigabit Ethernet—also allows for up to 5Gbps over Cat 6 cabling.

The new standard was specifically designed to bridge the copper-twisted-pair gap between Gigabit Ethernet (1Gbps), which is currently the fastest standard for conventional Cat 5e and Cat 6 cabling, and 10 Gigabit Ethernet, which can do 10Gbps but requires special Cat 6a or 7 cabling. Rather impressively work only began on the new standard at the end of 2014, which gives you some idea of how quickly the powers that be wanted to push this through.

While Cat 6a and 7 are growing in popularity, the vast majority of homes, offices, and institutions use Cat 5e and Cat 6—and upgrading the cabling would be very expensive indeed. A wired 1Gbps connection is still fairly adequate for a single PC user, of course—but over the last few years, with the explosion of high-speed Wi-Fi, Gigabit Ethernet is now one of the bottlenecks. For example, the top end of the 802.11ac spec eventually calls for a total aggregate capacity of around 6.5Gbps; even current consumer 802.11ac gear, which maxes out at around 1.3 or 1.6Gbps, is running up against the limits of GigE.

The new 2.5G/5GBASE-T standard (PDF) will let you run 2.5Gbps over 100 metres of Cat 5e or 5Gbps over 100 metres of Cat 6, which should be fine for most homes and offices. The standard also implements other nice-to-have features, including various Power over Ethernet standards (PoE, PoE+, and UPoE)—handy for rolling out Wi-Fi access points.

Oh No, The Final Fantasy Trading Card Game Launches In English Next Month

This is not good. The only thing standing between my wallet and the more than 2,000 cards in the Final Fantasy Trading Card Game was all of that Japanese text. Now Square Enix is launching the game in English. On October 28. Great.

For nearly six years, Japanese Final Fantasy fans have been greedily devouring booster packs of cards featuring art from the likes of Tetsuya Nomura, Yoshitaka Amano and Akihiko Yoshida—bright and colorful cardstock coated with images of their favorite characters from the franchise.

Western fans eager to play the game themselves have been importing cards and doing fan translations for years. Those poor bastards will have even more to buy now.

Launching in Europe and North America on October 28, the English version of the Final Fantasy Trading Card Game is starting us off mercifully slow. The first set, Opus 1, features only 216 cards, which doesn’t seem like much at all! I can probably afford that. The set features brand-new cards featuring characters and art from the Final Fantasy VII Remake, Dissidia and World of Final Fantasy, and each card in the set will have a premium foil counterpart.

Of all the characters to put on the first set, they chose Lightning. Okay. Via the Final Fantasy Twitter.

Wait, so that’s 432 cards. A set to play, and a set to collect? And of course you can’t build a deck with just one of each card. Oh god. This is going to hurt.

Starter sets, featuring Cloud, Tidus and Lightning.

The official Final Fantasy Trading Card Game website has tutorials and other goodies to help us prepare for the impending release. May cards have mercy on our souls.

Musk’s Mars moment: Audacity, madness, brilliance—or maybe all three

What the view of Mars might look like from inside the Interplanetary Transport System.

SpaceX

Elon Musk finally did it. Fourteen years after founding SpaceX, and nine months after promising to reveal details about his plans to colonize Mars, the tech mogul made good on that promise Tuesday afternoon in Guadalajara, Mexico. Over the course of a 90-minute speech Musk, always a dreamer, shared his biggest and most ambitious dream with the world—how to colonize Mars and make humanity a multiplanetary species.

And what mighty ambitions they are. The Interplanetary Transport System he unveiled could carry 100 people at a time to Mars. Contrast that to the Apollo program, which carried just two astronauts at a time to the surface of the nearby Moon, and only for brief sojourns. Moreover, Musk’s rocket that would lift all of those people and propellant into orbit would be nearly four times as powerful than the mighty Saturn V booster. Musk envisions a self-sustaining Mars colony with at least a million residents by the end of the century.

Bias Isn’t Just A Police Problem, It’s A Preschool Problem


A new study out of Yale found that pre-K teachers, white and black alike, spend more time watching black boys, expecting trouble.

A new study out of Yale found that pre-K teachers, white and black alike, spend more time watching black boys, expecting trouble.

LA Johnson/NPR

First, a story:

Late one night, a man searches for something in a parking lot. On his hands and knees, he crawls around a bright circle of light created by a streetlamp overhead.

A woman passes, stops, takes in the scene.

“What are you looking for? Can I help?”

“My car keys. Any chance you’ve seen them?”

“You dropped them right around here?”

“Oh, no. I dropped them way over there,” he says, gesturing vaguely to some faraway spot on the other side of the lot.

“Then why are you looking here?”

The man pauses to consider the question.

“Because this is where the light is.”

New research from the Yale Child Study Center suggests that many preschool teachers look for disruptive behavior in much the same way: in just one place, waiting for it to appear.

The problem with this strategy (besides it being inefficient), is that, because of implicit bias, teachers are spending too much time watching black boys and expecting the worst.

The Study

Lead researcher Walter Gilliam knew that to get an accurate measure of implicit bias among preschool teachers, he couldn’t be fully transparent with his subjects about what, exactly, he was trying to study.

Implicit biases are just that — subtle, often subconscious stereotypes that guide our expectations and interactions with people.

“We all have them,” Gilliam says. “Implicit biases are a natural process by which we take information, and we judge people on the basis of generalizations regarding that information. We all do it.”

Even the most well-meaning teacher can harbor deep-seated biases, whether she knows it or not. So Gilliam and his team devised a remarkable — and remarkably deceptive — experiment.

At a big, annual conference for pre-K teachers, Gilliam and his team recruited 135 educators to watch a few short videos. Here’s what they told them:

We are interested in learning about how teachers detect challenging
behavior in the classroom. Sometimes this involves seeing behavior before it becomes problematic. The video segments you are about to view are of preschoolers engaging in various activities. Some clips may or may not contain challenging behaviors. Your job is to press the enter key on the external keypad every time you see a behavior that could become a potential challenge.

Each video included four children: a black boy and girl and a white boy and girl.

Here’s the deception: There was no challenging behavior.

While the teachers watched, eye-scan technology measured the trajectory of their gaze. Gilliam wanted to know: When teachers expected bad behavior, who did they watch?

“What we found was exactly what we expected based on the rates at which children are expelled from preschool programs,” Gilliam says. “Teachers looked more at the black children than the white children, and they looked specifically more at the African-American boy.”

Indeed, according to recent data from the U.S. Department of Education, black children are 3.6 times more likely to be suspended from preschool than white children. Put another way, black children account for roughly 19 percent of all preschoolers, but nearly half of preschoolers who get suspended.

One reason that number is so high, Gilliam suggests, is that teachers spend more time focused on their black students, expecting bad behavior. “If you look for something in one place, that’s the only place you can typically find it.”

The Yale team also asked subjects to identify the child they felt required the most attention. Forty-two percent identified the black boy, 34 percent identified the white boy, while 13 percent and 10 percent identified the white and black girls respectively.

The Vignette

The Yale study had two parts. And, as compelling as the eye-scan results were, Gilliam’s most surprising takeaway came later.

He gave teachers a one-paragraph vignette to read, describing a child disrupting a class; there’s hitting, scratching, even toy-throwing. The child in the vignette was randomly assigned what researchers considered a stereotypical name (DeShawn, Latoya, Jake, Emily), and subjects were asked to rate the severity of the behavior on a scale of one to five.

White teachers consistently held black students to a lower standard, rating their behavior as less severe than the same behavior of white students.

Gilliam says this tracks with previous research around how people may shift standards and expectations of others based on stereotypes and implicit bias. In other words, if white teachers believe that black boys are more likely to behave badly, they may be less surprised by that behavior and rate it less severely.

Black teachers, on the other hand, did the opposite, holding black students to a higher standard and rating their behavior as consistently more severe than that of white students.

Here’s another key finding: Some teachers were also given information about the disruptive child’s home life, to see if it made them more empathetic:

[CHILD] lives with his/her mother, his/her 8- and 6-year old sisters,
and his/her 10-month-old baby brother. His/her home life is turbulent, between having a father who has never been a constant figure in his/her life, and a mother who struggles with depression but doesn’t have the resources available to seek help. During the rare times when his/her parents are together, loud and sometimes violent disputes occur between them. In order to make ends meet, [CHILD’s] mother has taken on three different jobs, and is in a constant state of exhaustion. [CHILD] and his/her siblings are left in the care of available relatives and neighbors while their mother is at work.

Guess what happened.

Teachers who received this background did react more empathetically, lowering their rating of a behavior’s severity — but only if the teacher and student were of the same race.

As for white teachers rating black students or black teachers rating white students?

“If the race of the teacher and the child were different and [the teacher] received this background information, severity rates skyrocketed,” Gilliam says. “And the teachers ended up feeling that the behavioral problems were hopeless and that very little could be done to actually improve the situation.”

This result is consistent with previous research on empathy, Gilliam says. “When people feel some kind of shared connection to folks, when they hear more about their misfortunes, they feel more empathic to them. But if they feel that they are different from each other … it may actually cause them to perceive that person in a more negative light.”

It’s impossible to separate these findings from today’s broader, cultural context — of disproportionately high suspension rates for black boys and young men throughout the school years, of America’s school-to-prison pipeline, and, most immediately, of the drumbeat of stories about black men being killed by police.

If implicit bias can play a role on our preschool reading rugs and in our classrooms’ cozy corners, it no doubt haunts every corner of our society.

Biases are natural, as Gilliam says, but they must also be reckoned with.

The good news, if there is such a thing from work such as this, is that Gilliam and his team were ethically obligated to follow up with every one of the 135 teachers who participated in the study, to come clean about the deception.

Gilliam even gave them an out, letting them withdraw their data — for many of them, the lasting proof of their bias.

Only one did.

Elon Musk’s Plan To Colonize Mars Gives Us The Sci-Fi Future We Crave

In Mexico today, SpaceX CEO Elon Musk outlined his company’s plans to take humanity to Mars.

Speaking at the International Astronautical Congress in Guadalajara, he unveiled a mission architecture that is bold, inspiring, and possibly a little crazy. It all centers around the Interplanetary Transport System–a 55-foot-wide pod-shaped spaceship concept–that would ride into orbit on a really big freakin’ rocket.
