$10.-- Laptop

India's $10 Laptop | TechWatch | Fast Company
On February 3, the Indian government will unveil a $10 educational laptop intended to bring computing to the masses, reports the Times of India. By comparison, a computer-shaped cake pan is $20 plus shipping in the U.S. Will the $10 PC revolutionize educational computing?

First, the specs: Like a lot of cheap PCs, the device will sport 2GB of RAM, Wi-Fi and expandable hardware, and operate on a modest two watts of power. The current prototype can be produced for about $20, according to India's Secretary for Higher Education, R.P. Agarwal. Large-scale production runs should cut that price in half, he said, resulting in the $10 figure the government is touting.

That's about one tenth the cost of the cheapest available PCs in the U.S. that retail for about $100, and operate on the old razor-and-blade business model; they require costly subscriptions to mobile broadband subscriptions.

The Indian government hasn't broken down the cost of its components, but it probably cut the costs of research and development substantially by recruiting university students to help draw up the plans. Students at the Vellore Institute of Technology played a significant role, working with state-funded organizations like the Indian Institute of Science, Bangalore and a partially-public entity called the Semiconductor Complex. Despite a publicly-funded development, the notebooks themselves will be manufactured on contract by private companies.

According to the Times of India, the $10 laptop is a direct response to the MIT-developed nonprofit One Laptop Per Child program, that was viewed as grossly expensive in India. The OLPC devices cost about $100 each, but "hidden costs" bring that price up to around $200. OLPC has also been a victim of its own poor strategy, evidenced by recent layoffs and a failure to secure donations and orders in 2008. The program has also seen itself dwarfed by Intel's [INTC] Classmate PC program, that most recently took an order from the government of Portugal for 500,000 PCs. The company still has big plans for a next-generation touch-screen notebook, however.

New Bike Transmission Design

Bike designers resurrect a 500-year-old idea to change the way people pedal

n the late 1990s, Donald Miller was creating “unsafe and impractical” low-profile lie-atop prototype bicycles in his machine shop (that is, his garage). “I just wanted to build a more efficient bike,” says the San Diego cyclist and former realtor turned inventor. Eventually, Miller instead shifted his focus to the drive train, convinced that the traditional chain-and-gear system was the primary factor holding back the evolution of the two-wheeler.

Special LED emitters


OMG Thes Things Are Cool
"Aimulet LA is designed to be held up to your ear like a cellphone. When you stand over special LED emitters set into the ground, Aimulet LA receives the light signals via an array of spherical micro solar cells (called Sphelar by manufacturer Kyosemi) set into the bottom of the handset. Aimulet LA translates the signals into audio messages that are transmitted through a tiny speaker in the device. In Laurie Anderson’s installation, visitors used Aimulet LA to listen to poems in four different languages as they strolled through a Japanese-style garden."

Bendable Concrete












A new type of fiber-reinforced bendable
concrete will be used for the first
time in Michigan this summer- and
University of Michigan scientists hope
that their new material will find
widespread use across the country.
The new concrete looks like regular
concrete, but is 500 times more
resistant to cracking and 40 percent
lighter in weight. Tiny fibers that comprise
about 2 percent of the mixture's
volume partly account for its
performance. Also, the materials
in the concrete itself are designed
for maximum flexibility. Because
of its long life, the Engineered Cement
Composites (ECC) are expected to cost
less in the long run, as well. Read more...

Speakers as thin as fabric

PNI, a Korean research firm, announced yesterday that it has developed a technology for mass production of flat speakers that are as flexible as a piece of fabric.
"This product will cause revolutionary changes in how speakers will look in the future," said Koh Seok-geun, president of PNI. "It took four years of studies after we initially developed the technology to make it available for mass production."
These speakers are thin transparent sheets that move like cloth.
They can be hung on walls, draped over an object or hung in a frame. One only needs to cut out a piece of the "cloth" and connect it to an amplifier with a wire.
The speakers are made with a type of plastic that is studded with electrodes. Until now, scientists had been unable to figure out a way to secure electrodes onto the vinyl, but scientists here said they used plasma on the electrodes to get it to adhere to the plastic.
The speakers, however, can only support sounds in the upper end of the register.
For instance, in a 5.1-channel home theater, four speakers are for treble and one is for bass. This fabric-like speaker, however, cannot support bass sounds.

The New Light Bulb

The lightbulb has remained virtually unchallenged since Edison invented it more than a century ago, but now scientists believe that zinc oxide—the same chemical that keeps diaper rash at bay—could provide a much-needed alternative to the inefficient lights that dominate our homes. In its crystalline form, zinc oxide can be used to make a light-emitting diode (LED) that could convert electricity to light 10 times as efficiently as the tungsten filaments used in today’s incandescent bulbs. It also lasts 10 times as long.

Tungsten shines white only when heated to 4,500 degrees Fahrenheit, an energy-sucking process that converts just 5 percent of electricity to visible light. “A zinc-oxide-based bulb, on the other hand, doesn’t require heat to produce light,” explains physicist David Look of Wright State University. And it glows brighter and more efficiently than other LEDs, because it emits mostly ultraviolet light, which is easily converted to visible light. Switching from tungsten to light sources like zinc oxide could reduce global electricity consumption for lighting by more than 50 percent.

The catch? The conversion will require expansive infrastructure changes, which the industry may be slow to embrace. But the long-term financial incentives, Look says, will be hard to ignore. Upgrading to zinc-oxide LEDs could help save Americans more than $35 billion a year.

Spinach

A house powered by spinach

10:44 AM architecture + green

Seattle architecture/design firm Mithun won first place in the C2C Home Competition with their design for a house powered by spinach. The house will be built this summer in Roanoke, Virginia, along with other contest winners.

The competition asked designers to work on work on cradle-to-cradle design principles and create objects and processes that replenish communities, using materials that can be recycled indefinitely.

Mithun's house takes energy from the sun and uses spinach protein to generate electricity for neighbouring homes and street lighting infrastructure.

The house's skylight brings in the sun's rays, and the heat sink stabilizes temperatures, while a highly conductive material produces photosynthetic energy generated from the protein in spinach. The spinach proteins are sandwiched between the core's glass walls; their chlorophyll converts the sun's rays to fuel the home. Besides, a vegetated roof system collects and filters stormwater into the building core

The geekiest bit will be where we edit our XML file, but you can essentially think of it just like editing a plain old text file it looks like garbledy-gook, but it's not actually rocket science. If you are new to web development or new to XML, don't worry all we will walk you through it as best we can.

New Hydrogen Bike

The world's first purpose-built hydrogen-powered bike could be fitted with an artificial "vroom" because of worries its silence might be dangerous. A prototype of the motorbike, which could cost more than $8,300 (£4,500), was unveiled in London on Tuesday. The problem with the "fuel cell" bike, which produces no polluting emissions, is that it is too quiet. Read More

Shoppers Pay For Their Products With Their Finger Prints


A German supermarket chain has introduced a new way of allowing customers to pay using just their fingerprints. Shoppers have to run a finger over a scanner at the cash desk to confirm their purchases, and receive the goods. Customers have to register for the service by signing an agreement allowing Edeka to debit unpaid purchases from their bank accounts. Edeka spokesman, Gert Duschan, said that a trial will be conducted in Ruelzheim, near the Belgian border. If it proves successful the system will be made available for all branches. Read More
