Self-Assembling Batteries:  "Researchers at MIT have designed a rechargeable lithium-ion battery that assembles itself out of microscopic materials. This could lead to ultrasmall power sources for sensors and micromachines the size of the head of a pin. It could also make it possible to pack battery materials in unused space inside electronic devices."  Earlier related story:  Batteries That Assemble Themselves: "Biology may be the key to producing light-weight, inexpensive, and high-performance batteries that could transform military uniforms into power sources and, eventually, improve electric and hybrid vehicles. Angela Belcher, an MIT professor of biological engineering and materials science, and two colleagues, materials science professor Yet-Ming Chiang and chemical engineering professor Paula Hammond, have engineered viruses to assemble battery components that can store three times as much energy as traditional materials by packing highly ordered materials into a very small space."  3:08:44 PM  permalink  

Researchers convert heat to electricity using organic molecules:  "Arun Majumdar, UC Berkeley professor of mechanical engineering was principal investigator of the study..  [His team] successfully generated electricity from heat by trapping organic molecules between metal nanoparticles, an achievement that could pave the way toward the development of a new source for energy."  While it's a long way from marketable form, it would have implications for energy, nanomaterials, and sensors (which need small amounts of energy to function).

Wireless Telemetry Growing to $25.3bn by 2009, as Enterprise Wakes up to Real-Time Efficiency Savings:  "wireless telemetry (or AMR – Automated Meter Reading) will [grow] - according to industry analysts Juniper Research - with revenues rising from $11.6bn in 2006 to $25.3bn by 2009.  According to Juniper, the substantial rise in revenues - expected to quadruple by 2011 to $40.8bn - will contrast with limited growth in telematics from $6.4bn to $11bn in the same period – owing to current widespread usage in many commercial vehicles due to legislation. Other outlets including security and surveillance, highway and public transport signs, and health care will show encouraging signs rising from a cumulative low of $2bn in 2006 to over $9bn by 2009."

Biofuels via cellphone:  "More people would be likely to refuel with biodiesel if they knew where to find a filling station .. NearBio delivers a database of more than 1,000 biodiesel sellers to mobile phones via WAP (wireless access protocol) or text messaging. The free applet and service from WHDC of Nevada City, CA, provides driving directions, the phone number and the blends available at the five closest locations.

Since most of the diesel engines in the U.S. are inside of trucks, truck drivers who can factor biodiesel stations into their routes are the most likely beneficiaries of this service. The number of biodiesel stations is increasing rapidly and NearBio says it will add new locations within a day. "

Taking the Measure: IT and Energy:  I've heard these numbers verbally before, but not online; I've asked the author for the reseach citation.  "According to researchers at MIT, less than 1 percent of all commercial and industrial companies use advanced technology to measure and manage energy spend. On the other hand, nearly 100 percent of companies use advanced technology to measure and manage telecommunications spend.  Now consider that, according to the MIT researchers, the U.S. spend in electricity is about $270 billion per year while the U.S. spend in telecommunications is about $125 billion per year.

Does your company know down to the fraction of a minute how your telecommunications bill is derived?  Probably, and you can probably produce pages of reports showing spending by person, department and project. .. Can you also break out by building, department, project and individual worker how your electrical bill is derived? Or your heating bill? Or your air-conditioning bill? I doubt it, but that is where your next round of cost savings resides."

Sensors watch Barrier Reef coral: Cairns, Australia:  "The Australian Institute of Marine Science (Aims) is working with James Cook University on a project called Digital Skins. Smart sensors, developed originally for use in nuclear power stations, are placed in the ocean and also in water catchments on the mainland.  They are able to communicate with each other to monitor events such as coral bleaching as they happen. ..
 
Each sensor in the skin has its own numerical address and operating system. Using a global position system, the sensors know exactly where they are. Parameters such as salinity, temperature and nutrient levels are measured. 

Communicating with the sensors is a challenge, particularly for those sensors located out on the reef.  Using a technique that was discovered by the British during World War II, microwave signals are sent along the surface of the ocean.  Initial tests have seen data sent as far as 70km (43.5 miles) in one hop.

The final link in the chain is grid computing. All these sensors create terabytes of data every day.  High-speed links allow the various institutions to share their computing power. "

When Pigs Wi-Fi:  Free WiFi works in rural Oregon:  "this chunk of arid farm country appears to be the largest Wi-Fi hot spot in the world, with wireless high-speed Internet access available free for some 600 square miles. Most of that is in eastern Oregon, with some just across the border in southern Washington .. Morrow and Umatilla Counties in eastern Oregon are far ahead of them in providing high-speed Internet coverage to residents, schools and law enforcement officers - even though all of Morrow County doesn't even have a single traffic light. .. [WiFi] is free for consumers and has been up and running for more than a year and a half.

One reason it sprang up here is that a nearby Army depot contains chemical weapons, so there is special concern about what would happen if a cloud of nerve gas escaped from the depot. That fear helped provide a pot of federal money to underwrite safety systems.  Usually, the police and fire agencies communicate just by radio, but Hermiston decided to go with a public-private partnership that established a Wi-Fi network. .. all police officers now carry [wireless computers that] download data and receive images from video monitors - and, if nerve gas ever escaped, display the cloud's direction and speed.

Fingerprint readers are now being added to these portable devices so a police officer can almost instantly run a person's fingerprint through a multistate database. And if there's a report of a burglary, the police rushing to the scene can download floor plans of the building, live images from video monitors and information about the alarm system. ..

Hermiston is already starting to introduce WiMax, the next generation of technology after Wi-Fi, offering much higher speeds and greater range."

Wireless reef monitoring: Five senior engineering students at UC Santa Cruz are trying to push the limits of low-power wireless transmission to facilitate the monitoring of remote natural environments.  The apparatus they are building will track conditions on coral reefs in distant locations and beam information back in real time to a land-based station.  The students named their creation SEA-LABS, short for "Sensor Exploration Apparatus utilizing Low-power Aquatic Broadcasting System."  SEA-LABS was originally designed to help UCSC biologist Donald Potts track environmental changes that affect the reefs of Midway, a remote atoll of the Hawaiian archipelago. But SEA-LABS also has the potential to become a low-cost tsunami-warning device, said Matt Bromage, a computer engineering student who acts as SEA-LABS team manager. ..

Now entering its final testing stages, the project should culminate this summer with a trip to the Midway atoll, 1,200 miles northwest of Honolulu, where the students will install and test their waterproof and salt-resistant prototype.  ..  The core of SEA-LABS is a Programmable Ocean Device (POD), which consists of a processor, a memory storage component, and a battery that can last up to two years, all housed in a waterproof casing about the size of a small wastebasket. The POD can be bolted to the seafloor near a reef. .. The POD has cable connections to sensors that independently record pressure, light, salinity, and temperature. The sensors are small enough to fit in any desired location on or within a reef and can be placed right next to plants, corals, and other reef inhabitants. .. The POD connects to a receiver/transmitter attached to a surface buoy. The transmitter broadcasts the data recorded by the sensors from the POD to a base station on land via a radio antenna. ..

The students use off-the-shelf components and develop nonproprietary open-access software. Depending on the number of sensors attached to each POD, SEA-LABS should cost between $500 and $1,000 per POD."

Samsung Builds Flash Based Disk Drive: "Samsung says it has developed a way to store up to 16GB of data using Flash memory, a development that could lead to extended battery life for notebook and tablet PCs. Flash memory has a power consumption that is five percent of today's hard disk drive, according to the company.  These solid-state disk (SSD) Flash-based drives will also provide faster access to data, at about two-and-a-half times the speed of current notebook hard drives. In tests, Samsung was able to read data at 57 megabytes per second (MBps) and write at 32MBps."  That's 2-3 GB/Min, comparable in my experience to desktop HD.

"Flash drives also offer the benefit of less noise and heat emissions. They are also less temperature- and humidity-sensitive, meaning Flash-based drives can be used in a wider array of applications and environments.  The disk drive itself will look much like a regular 1.8-inch hard disk drive, meaning manufacturers will have to make minimal adjustments to PC designs in order to incorporate the new drives. .. SSD Flash drives based on the new technology are expected on the market by August of this year."  They would be useful in off-grid locations, in developing countries or in sensor apps.  I wonder if the price will remain at today's $30-50/GB or will be lower.

How SMS Could Save Your Life: Cell phones are being used "to manage the treatment of HIV/AIDS in [South Africa] where health care systems are overburdened and doctors are scarce. ..

Therapeutic counselors fill a crucial gap at the Gugulethu clinic, where 525 patients taking ARV drugs are served by just two doctors and two nurses. They visit patients at home and count pills. They take note of conditions that interfere with treatment, such as the absence of food in the house. In short, they are the first line of defense against problems with side effects and drug resistance that can develop if treatment isn't managed properly. In the past, this job involved writing out the cumbersome details of each home visit by hand. But as the clinic data accumulated and the number of patients on treatment grew, the system became unmanageable..

They [now] use SMS to send all of this information to a central database, where Sister Mtwisha can instantly view it on her computer screen. With all of the relevant information compiled neatly in front of her, the irregularities stand out. .. "I used to pick up some faults in the system after a week or a month," she says. "Now I send a message and things are sorted out on the spot, without having to wait." ..

The system, which runs on open-source software, is inexpensive and can easily be managed remotely and adapted for various projects. ..

"If a patient in Gugulethu goes to the Eastern Cape and gets sick and goes to a clinic, they would need to know what drug regimen he's been on, what side effects he had, whether he was hospitalized," she says. "We need to get a system like an ATM where you can get money from every bank. We need something like that for HIV."  The Cell-Life project, started by civil engineering faculty and students at the University of Cape Town and the Cape Technikon, has enlisted engineers and computer programmers to provide just that. 

Meanwhile, a number of other clinics have expressed interest in using the system, but it has been difficult to raise funds to expand the program. Most donors would rather buy drugs than spend money on systems for distributing them, Rivett says.  Instead of donating money, however, she maintains that large companies like Coca-Cola could make an even greater contribution by sharing their knowledge in areas like distribution and product management.  "You find Coca-Cola in rural villages everywhere, but you don't find drugs," she says. "The Coca-Colas and the Unilevers can make sure their products get to these places. We need to use these guys to help us get drugs into every single clinic."

From your own email folders to healthcare history to fully functional work applications, U3 makes everything available anywhere without having to access multiple devices or lug around a laptop." 

Memorex, Kingston, and Verbatim have promised products: "Called a smart USB flash drive, these drives enable consumers to carry all of their personal computer settings, applications and data for use on any PC wherever they go. The new Verbatim smart Store ‘n’ Go USB flash drives will be availabe worldwide [in 2005]. .. The U3 platform includes three components.

The U3 Launchpad is a friendly graphical user interface that is used to access and run applications." 

This could improve the utility of internet cafes: users can keep an offline personalized environment and secure information store for a small purchase price.  Many of today's UFDs play and record sound; with U3, they could rapidly download and upload voice mail at an internet cafe to extend VOIP services (e.g., in developing countries).  The U3 could be added to an entertainment device, like an MP3 player, radio, game machine or camera, making the net cost per user negligible.
