Google Aids Green Action

Google has a focus on energy as I have discussed previously. Google has been working to provide a way for people to get information on energy use in their homes that can be used to reduce your energy use.

Power to the people

studies show that access to home energy information results in savings between 5-15% on monthly electricity bills. It may not sound like much, but if half of America’s households cut their energy demand by 10 percent, it would be the equivalent of taking eight million cars off the road.
…
We’ve been participating in the dialogue in Washington, DC and with public agencies in the U.S. and other parts of the world to advocate for investment in the building of a “smart grid,” to bring our 1950s-era electricity grid into the digital age. Specifically, to provide both consumers and utilities with real-time energy information, homes must be equipped with advanced energy meters called “smart meters.” There are currently about 40 million smart meters in use worldwide, with plans to add another 100 million in the next few years.
…
Over the last several months, our engineers have developed a software tool called Google PowerMeter, which will show consumers their home energy information almost in real time, right on their computer. Google PowerMeter is not yet available to the public since we’re testing it out with Googlers first.

Teen Goalie Designs Camouflage Pads

Teen goalie designs pads to trick shots

Leahy sketched out new leg pads that blend into the goal netting behind him. He wanted pads, a trapper, and a blocker that are white with a raised double-stitched design, just like the goal. He applied for a design patent and had them custom-made by a Canada-based pad maker.

“When the shooter comes down and only has a split second to shoot the puck, they’re looking for net,” said Leahy, a senior from Hampton, N.H., who grew up in Byfield. “If you put the net on the pad, they’ll shoot at the pad instead of the goal.”
…
Exactly what will happen to the pads after this season is unclear. Leahy said he would like to play hockey in college, probably at the club level, and wants to market the idea. “It would definitely be cool to get it out there and get other guys in the future wearing it,” he said.

MRI That Can See Bacteria, Virus and Proteins

IBM team boosts MRI resolution

The researchers demonstrated this imaging at a resolution 100 million times finer than current MRI. The advance could lead to important medical applications and is powerful enough to see bacteria, viruses and proteins, say the researchers.

The researchers said it offered the ability to study complex 3D structures at the “nano” scale. The step forward was made possible by a technique called magnetic resonance force microscopy (MRFM), which relies on detecting very small magnetic forces.

In addition to its high resolution, MRFM has the further advantage that it is chemically specific, can “see” below surfaces and, unlike electron microscopy, does not destroy delicate biological materials.

Now, the IBM-led team has dramatically boosted the sensitivity of MRFM and combined it with an advanced 3D image reconstruction technique. This allowed them to demonstrate, for the first time, MRI on biological objects at the nanometre scale.

That is very cool.

Student Invents Solar-Powered Fridge

Student Invents Solar-Powered Fridge for Developing Countries

21-year-old student/inventor/entrepreneur Emily Cummins has designed a brilliant portable solar-powered refrigerator that works based upon the principle of evaporation. Employing a combination of conduction and convection, the refrigerator requires no electricity and can be made from commonly available materials like cardboard, sand, and recycled metal.
…
Simply place perishable foods or temperature-sensitive medications in the solar refrigerator’s interior metal chamber and seal it. In-between the inner and outer chamber, organic material like sand, wool or soil is then saturated with water. As the sun warms the organic material, water evaporates, reducing the temperature of the inner chamber to a cool, 6 ÂºC [43 ÂºF] for days at a time!

After winning Â£5,000 from York Merchant Adventurers for her idea, Emily delayed going to college for a year to take her refrigerator to Africa for further development.
…
At 16 Emily won a regional Young Engineer for Britain Award for creating a toothpaste squeezer for people with arthritis, and the next year went on to win a Sustainable Design Award for a water-carrier made from wood and rubber tubing. In 2007 Emily was named the British Female Innovator of the Year, and last year was short-listed for Cosmopolitan’s 2008 Ultimate Women of the Year Competition.

Update: some readers seem confused by what related means below. Those links show previous post to related items and include previous similar designs to keep things cool, including “Refrigerator Without Electricity” which is a clay pot design by Mohammed Bah Abba of Nigeria for the Pot in Pot Cooling System that received the 2000 Rolex award.

Moving Closer to Robots Swimming Through Bloodsteam

Pretty cool. Tiny motor allows robots to swim through human body

James Friend, of Monash University, said that such devices could enter previously unreachable brain areas, unblocking blood clots, cleaning vessels or sending back images to surgeons. “The first complete device we want to build would have a camera,” Professor Friend said.
…
Professor Friend said they had shown the motor, which is a quarter of a millimetre wide, had enough power to navigate this type of nanorobot through the bloodstream of a human artery. Tests of their prototype device in a liquid as viscous as blood were also promising. “It swam.”
…
The team plans to conduct animal tests of a nanorobot driven by their motor later this year or early next year. But Professor Friend cautioned that many technical hurdles needed to be overcome.

Their miniature motor was connected to an electricity supply and a way would need to be found to power it remotely. The construction of the flagella also needed refinement.

Eliminate Your Phone Bill

I have written about Innovation Thinking with Clayton Christensen on the Curious Cat Management Blog previously. Here is an example of such innovation. All you need is a broadband internet connection and you can Kiss your phone bill good-bye:

The Ooma service uses so-called Voice over Internet Protocol (or VOIP) technology to deliver calls to your existing phone using a broadband connection. Consumers need only to buy a $249 Ooma Hub (it was a hefty $399 when the service launched last year); all domestic calls are free. (Ooma charges a few pennies a minute for international calls to landlines and 20 to 30 cents a minute for overseas calls to mobile phones. Calls from Ooma box to Ooma box are free.)
…
Replacing your phone service is, of course, just the start for Ooma. In some ways, calling is the Trojan horse to get the box in your house and then figure out other services to sell, like enhanced network security or kid-safe Web surfing.

I ordered mine from Amazon for $203 and have been using it for a little over a month; it has been great. Relatively easy to setup (they had a pretty good customer survey and I recommended they use colored cables – they color cables in the drawings in the users guide but give you 3 white cable to use – they are different types of cables so it isn’t tough to figure out but that would make it a bit easier).

I have been using Vonage for awhile and it is ok, but I don’t see any reason to pay each month when Ooma doesn’t charge a monthly fee (even on the lowest option on Vonage the bill is over $22/month).

I think gadgets are cool, but I will admit most of the time I don’t really want to be bothered to actually use them. But this is easy to you and saves me $20/month, that I like.

Making Magnificent Mirrors with Math

At Drexel, he designs amazing mirrors

Could math provide the path to better reflection? Perline asked.

Indeed it could. Eight years and numerous calculations later, Hicks is now testing a prototype mirror – for a car, not a bike – and he is in talks with a foreign manufacturer. As with the bike mirror, the rounded surface provides a wide field of view – so wide that it eliminates the dreaded, driver-side “blind spot” – yet the subtle mathematics of his design result in little or no distortion.

He didn’t stop there. The 42-year-old mathematician went on to design half a dozen other reflective surfaces for various applications – a few of them in collaboration with Perline – and they are like nothing you’d ever see on the bathroom wall.

Panoramic mirrors. Mirrors for use with high-tech surveillance cameras. Mirrors with odd, undulating surfaces that are fashioned with a computer-guided milling machine. And one wacky mirror that doesn’t yield a mirror image at all. If you raise one hand while looking into the curved surface, your reflection appears to be raising the opposite hand.

It’s not clear what use that one will have, beyond entertainment – Perline calls it “the vampire mirror” – but with his driver-side prototype, Hicks may be onto something.

Tiny $10 Microscope

Researchers at Caltech, who developed the revolutionary imaging system, say that the devices could be mass-produced at a cost of $10 each and incorporated into large arrays, enabling high-throughput imaging in biology labs. The device could also broaden access to imaging technology: incorporated into PDA-size devices, for example, the microscopes could enable rural doctors to carry sophisticated imaging systems in their pockets.

The Caltech device uses a system of tiny fluid channels called microfluidics to direct cells and even microscopic animals over a light-sensing chip. The chip, an off-the-shelf sensor identical to those found in digital cameras, is covered with a thin layer of metal that blocks out most of the pixels. A few hundred tiny apertures punched in the metal along the fluid channel let light in. As the sample flows through the microscope, each aperture captures an image. One version of the microscope uses gravity to control the flow of the sample across the apertures. Another version, which allows for much better control, uses an electrical potential to drive the flow of cells.

Solid-State Drives For Laptops

SanDisk Drops Price On Solid-State Drives For Laptops

The products are scheduled to be available in the middle of this year.
…
SanDisk claims the SSDs are more than five times faster than the fastest 7,200 revolutions per minute hard-disk drives used in laptops. The vendor also claims its devices are more than twice as fast as SSDs that shipped last year.

The latest devices operate at a 40,000 vRPM, or virtual RPM, a metric used to compare the speeds of SSDs and HDDs. The SanDisk drives read and write data at 200 MBps and 140 MBps, respectively.

“With large capacities and aggressive pricing, SSDs are poised to enter mainstream corporate notebooks in 2009,” Rich Heye, senior VP and general manager of SanDisk’s SSD business unit, said in a statement.
…
SSDs use flash memory chips to store data, so have no moving parts. As a result, the technology is quieter, uses less power and is more reliable than HDDs. In addition, SSDs are faster and are more rugged.
