Huzzah! Yet another discovery for us to add to our ever-expanding list of “awesome things that’ll never actually happen!” Ibrahim Abou Hamad and colleagues from Mississippi State University have reportedly devised a method of charging batteries that could hasten the process rather significantly, and better still, it could provide “an increase in battery power densities” as well. The only problem? Lithium-ion batteries have been disappointing tech users for years, and so long as Energizer and Duracell are calling the shots, we kind of doubt a lot will be done to improve the longevity of ’em. Skepticism aside, the new method involves some fancy black magic surrounding molecular dynamics simulations, and researchers have found a way to boost charging time by “simulating the intercalation of lithium ions into the battery’s graphite anode.” We know we just went way over your heads on a Friday afternoon, but if techobabble’s your thing, all you can handle is right there in the Source link.

The renowned MIT Media Lab is a place where every project is an amazing, unbelievable glimpse into humanity’s technological future. Now, thanks to a massive $90 million extension, the architecture can match the wondrous excitement created within.

In case you haven’t had the opportunity to swing by this particular block in Cambridge, Massachusetts, here’s what the old Media Lab looks like. It’s still there. In fact, you can see the extension under construction, and marvel at the stark contrast in design.

Mensa Tetris

The six-level, interconnected extension, the work of the famed, award-winning architectural firm Fumihiko Maki and Associates, is like an immense Tetris puzzle. Every piece represents a functional element that is tightly connected to others, giving anyone inside the feeling of being inside a finished puzzle. Maki, himself the winner of a Pritzker Prize, was on hand over the weekend to officially open the MIT Media Lab. (It’s technically been in operation since December.)

As he described it, each piece of this six-level building connects to the next. Balcony offices overlook open air labs and work spaces. Colorful stairways bisect the central atrium, their red, blue and yellow coloring inspired by Piet Mondrian’s Composition with Yellow, Blue and Red.

Color aside, the trait hitting visitors in the face before they even walk through the door is glass. Cambridge building codes prevented a 100% glass exterior, so Maki came up with a loophole: bamboo. Inspired by translucent Japanese bamboo screens, Maki covered the remaining exterior with a mix of glass and aluminum tubes.

The result is at the same time beautiful and energy efficient, but also functional. We’re constantly reminded that this is one incredibly open, collaborative working environment.

From the street, especially at night, passers-by can literally see lab work happening within. Maki called this “filtered views,” inspired by the work of the pointillist artist George Seurat (lots of dots!). MIT played a part too, having provided Maki with an image of the Visible Man to further drive home the point that this lab space be open.

But enough architecture? What kind of world-changing stuff can we expect this multimillion dollar, 163,000-sq. ft. incubator to pump out in the future?

Well, if the past is any indication, plenty. The place that saw the beginnings of Guitar Hero, e-ink displays, OLPC and Lego Mindstorms is still driving much of the stuff that gets the Gizmodo editors, at least, sweating profusely in their blogging sweatpants.

The Media Lab will help “plumb the depths of how technology can have a greater impact on industry, society and business,” said Media Lab director Frank Moss.

To net denizens and geeks like you and me, that boils down to robotics, prosthetic limbs, AI and the obligatory Minority Report UI reference that any article mentioning 3D interfaces must include.

Fluid Media

As part of the opening, I was lucky enough to get a tour or some, but not all of the departments at the Media Lab. Departments like Biomechatronics, Cognitive Machines, Fluid Interfaces, Molecular Machines, Personal Robots, Smart Cities, Synthetic Neurobiology. It reads like Stephen Hawkings’ shopping list.

In any event, Fluid Media was one of the labs I got to tour first.

If you know Arduino, you’d be at home here, alongside the luminescent wallpaper, smart fabrics, “sewable computing” and inexpensive 3D fabricators that had me waxing nostalgic about Cory Doctorow’s Makers.

Above: No, not coasters or doilies. Sewable computers. If you aren’t wearing your mp3 player now, you will be soon.

Kindergarten Kids, Forever

The sense of play felt throughout the Media Lab’s open spaces owes itself to the students, of course, but it’s certainly assisted by the design. Moss called the atmosphere “serious fun,” in a building where bright minds “design by serendipity.” It’s pretty spot on. One lab leads into the other, encouraging social and professional interaction. Artists huddle with biomechanical engineers. Sometimes the union is short-lived, and sometimes it’s Guitar Hero.

But it’s serious fun: There’s a mission here, one that’s produced limbs for soldiers maimed in war; helped children learn robotics with crazy new Lego software; and created a paint brush, simply called I/O, that captures the essence of whatever you point it at—visual, musical or otherwise.

Even so, the fun, relaxed environment is apparent in this lab that director Moss says will change our futures. He and others, like Lifelong Kindergarten Department grad student Karen Brennan, were genuinely having fun while working with these high concepts and brain-bending experiments. The future, wild as it will be, looks pretty fun. Seriously.

Microsoft looks to be on a bit of a hot streak with innovations lately, and though this here project hasn’t received much hype (yet), we’d say it’s one of the most ingenious user interface concepts we’ve come across. Skinput is based on an armband straddling the wearer’s biceps and detecting the small vibrations generated when the user taps the skin of his arm. Due to different bone densities, tissue mass and muscle size, unique acoustic signatures can be identified for particular parts of the arm or hand (including fingers), allowing people to literally control their gear by touching themselves. The added pico projector is there just for convenience, and we can totally see ourselves using this by simply memorizing the five input points (current maximum, 95.5 percent accuracy), particularly since the band works even if you’re running. Make your way past the break to see Tetris played in a whole new way.

Solar cells are cute and all, but let’s be real — these things are far too inefficient for mainstream use. Scientists at the California Institute of Technology are working hard to remedy that very issue, and they’ve recently concocted a “new type of flexible solar cell that enhances the absorption of sunlight and efficiently converts its photons into electrons.” The solution relies on arrays of long, thin silicon wires embedded onto a polymer substrate, which uses just a fraction of the expensive semiconductor materials required by conventional solar cells. According to professor Harry Atwater, these cells have “surpassed the conventional light-trapping limit for absorbing materials” for the first time, and we’re told that the arrays can convert between 90 and 100 percent of the photons they absorb into electrons, and yes, that does mean that they have a near-perfect internal quantum efficiency. Hit the source link for all the technobabble, and cross your fingers for this stuff to get the honored approval of the Governator.

You don’t think the Robot Apocalypse is upon us, but we assure you, it is. The HUMAVIPS project, which will span three years and hopefully result in robots being developed with “social skills,” may seem innocent — even beneficial — at first blush, but let’s think about it. Will “humanoids with auditory and visual abilities in populated spaces” have more power than you, as an Earthling, would like? If all goes well, these robotic dudes and dudettes will be able to mimic what’s known as the “cocktail party effect,” which is better explained as “the human ability to focus attention on just one person in the midst of other people, voices and background noise.” So yeah, this definitely goes two ways — on one hand, you could finally have a live-in robot that pays attention to your feelings as the world around you crumbles, but on the other, these guys won’t have any issue overlooking your wailing when it’s them bringing everything down. Yikes.
