Sugar batteries could be greener, cheaper and store more energy than lithium-ions

Sugar batteries could be greener, cheaper and store more energy than lithium-ions | Items of Interest | Scoop.it

Even today's best rechargeable lithium batteries do lose their ability to hold a charge after a while, and are considered toxic waste once discarded. In just a few years, however, they may be replaced by batteries that are refillable and biodegradable, and that will also have a higher energy density yet a lower price ... and they'll run on sugar.

"Sugar is a perfect energy storage compound in nature," says Virginia Tech's Prof. Y.H. Percival Zhang, who is leading the research. "So it's only logical that we try to harness this natural power in an environmentally friendly way to produce a battery."

Zhang's isn't the first experimental sugar battery, although he claims that its energy density is "an order of magnitude higher than others."

It's actually a type of enzymatic fuel cell. For fuel, it utilizes maltodextrin, which is a polysaccharide made from the hydrolysis of starch (polysaccharides are chains of sugars). The catalyst in its anode is made from inexpensive enzymes, as opposed to the costly platinum that's used in regular batteries.

When the maltodextrin is combined with air, water and electricity are produced. Unlike the case with a hydrogen fuel cell, however, the sugar battery is non-explosive and non-flammable.

Zhang envisions users refilling the batteries with sugar when they need refueling, "much like filling a printer cartridge with ink." He hopes that they may be powering electronic devices in as little as three years.

Everything we do and say is story. All standard story structures ask the question 'who am I?' and try to make the answer interesting - or we stop caring. The rules here contain some great visuals and a lot of thought-provoking ideas. Go be provoked.

Someday Somewhere Beyond

Imagine a city in space, a round structure miles across that millions of people would call home. Engineers working at NASA in the 1970s developed colorful proposals for permanent settlements in space, but their plans were shelved and forgotten. Decades later, a new generation of dreamers from high schools around the world aspire to mine asteroids, terraform other planets, and venture to the stars. The students have come together for a contest at NASA, and have big plans for the next millennium.

that shouldn't even be an option of theirs. Of course your information will be shared on the inernet but it's a person's right to show it or not, especially if it's being used without permission to advertise.

How a Radical New Teaching Method Could Unleash a Generation of Geniuses | Wired Business | Wired.com

How a Radical New Teaching Method Could Unleash a Generation of Geniuses | Wired Business | Wired.com | Items of Interest | Scoop.it
Students in Matamoros, Mexico weren't getting much out of school -- until a radical new teaching method unlocked their potential.

-

José Urbina López Primary School sits next to a dump just across the US border in Mexico. The school serves residents of Matamoros, a dusty, sunbaked city of 489,000 that is a flash point in the war on drugs. There are regular shoot-outs, and it’s not uncommon for locals to find bodies scattered in the street in the morning. To get to the school, students walk along a white dirt road that parallels a fetid canal. On a recent morning there was a 1940s-era tractor, a decaying boat in a ditch, and a herd of goats nibbling gray strands of grass. A cinder-block barrier separates the school from a wasteland—the far end of which is a mound of trash that grew so big, it was finally closed down. On most days, a rotten smell drifts through the cement-walled classrooms. Some people here call the school un lugar de castigo—”a place of punishment.”

For 12-year-old Paloma Noyola Bueno, it was a bright spot. More than 25 years ago, her family moved to the border from central Mexico in search of a better life. Instead, they got stuck living beside the dump. Her father spent all day scavenging for scrap, digging for pieces of aluminum, glass, and plastic in the muck. Recently, he had developed nosebleeds, but he didn’t want Paloma to worry. She was his little angel—the youngest of eight children

An answer to the 'Jane Austen problem': Kissing assesses the genetic quality of a potential sexual partner

An answer to the 'Jane Austen problem': Kissing assesses the genetic quality of a potential sexual partner | Items of Interest | Scoop.it

Kissing is a way for people to assess the genetic quality of a potential sexual partner and is especially important for women to size up a future husband according to a study into the “Jane Austen problem”.

Anthropologists have long argued about why humans are particularly prone to kissing which appears to be a near universal behaviour among potential lovers, and now they think they have come close to explain why it is so important.

A survey of 900 men and women confirmed that kissing appears to play a central role in assessing a future partner, which is especially important for the Ms Bennets of the world who are in search for their Mr Darcys, said Professor Robin Dunbar of Liverpool University.

“Mate choice and courtship in humans is complex. It involves a series of periods of assessments where people ask themselves 'shall I carry on deeper into this relationship?' Initial attraction may include facial, body and social cues. The assessments become more and more intimate as we go deeper into the courtship sage, and this is where kissing comes in,” Professor Dunbar said.
