#ENERGY: "Fuel Cell Rechargers Finally Here"

Researchers have finally transferred experimental fuel cells from the lab to handheld recharging stations that can replenish batteries in regions where electricity is scarce—from campsites to third-world outback. Look for fuel cell rechargers to become standard backpack equipment by 2012. R. Colin Johnson @NextGenLog


The fuel cell from myFC AB uses a SiGNa PowerPukk cartridge.

Here is what my Smarter Technology story says about fuel cells: University of Michigan spinoff SiGNa Chemistry Inc. claims to have solved the fuel cell problem, at least for small devices, with a replaceable hydrogen-bearing cartridge that can be used to generate electricity anywhere a tablespoon of water is available.
Fuel cells were supposed to rescue automobiles from the need for fossil fuels by consuming clean hydrogen instead of gasoline, but unfortunately the rigorous specifications for safety and longevity has put all-electric cars ahead of fuel cells for transportation power. However, for small devices like cell phones, SiGNa's new Mobile-H2 cartridges can supply the hydrogen needed to recharge batteries anywhere that line power in unavailable.

#ALGORITHMS: "What's next for IBM's Watson?"

The stunning victory of IBM's Watson cluster computer over human champions Ken Jennings and Brad Rutter on the quiz show Jeopardy proved that artificial intelligence algorithms make the system capable of being an expert's advisor. Look for IBM to bring out a whole array of Watson-like helper applications or human experts over the next three years. R. Colin Johnson @NextGenLog


Watson was the last contestant standing after having knocked the humans out cold.

Here is what my follow-up story for EETimes says about Watson: IBM is currently adapting Watson DeepQA architecture to commercial applications, where it will act as an advisor to human experts, thus defusing criticisms that it is not an expert itself (after Watson asserted during the Jeopardy game that Toronto was a U.S. city). By filtering Watson's advise through the expertise of a human—to eliminate such obvious mistakes—IBM hopes to apply Watson to a variety of fields, including healthcare, financial services, government-mandate management and retailing...

#ALGORITHMS: "Augmented Reality: From Zero to Billions in No Time"

The augmented reality market, which overlays tactical information onto real-world objects when you point your cell phone camera at them, is poised to rise from a paltry $21 million in 2010 to $3 billion by 2016. Look for app developers to reaping the lion's share of that windfall over the next five years. R. Colin Johnson @NextGenLog


The Wikitude World Browser can supply information about sites of interest; here, the Statue of Liberty.

Augmented reality (AR) will transform mobile computing by enabling "zero-click interfaces" that append information on things in the real world when users point their camera phones at them. Eventually, everything from ice-cream shops to server farms will pop up information on demand using AR. For example, retailers will offer special deals you can see only in AR, and equipment suppliers will append specifications and upgrade information directly to their products.

The world’s largest maker of micro-electro-mechanical systems (MEMS) chips announced it has teamed with pico-projector pioneer bTendo to develop the world’s smallest, lowest-power pico-projector for smartphones and other portable consumer electronics devices. Look for pico-projectors to become standard equipment on smartphones by the end of the decade. R. Colin Johnson @NextGenLog


Israel's bTendo marries lasers with beam-steering using micromirrors that combine the illumination from three lasers (red, green, blue) then deflect it to the proper pixel by steering the laser beams in two dimensions—fast horizontal and slow vertical.

Here is what my Smarter Technology story says about MEMS trends: Pico-projectors promise to enable even the smallest-screen smartphones to project 50- to 100-inch displays onto any flat, white surface. Texas Instruments (TI, Dallas, Texas) currently leads with its digital-light processor (DLP), but now STMicroelectronics (Geneva, Switzerland), the world's largest MEMS chip maker, has thrown its weight behind a relatively unknown startup with a novel, two-mirror design...

Here is what my Smarter Technology story says about photosynthesis: The Department of Energy's Oak Ridge National Laboratory claims to have found a way to combine synthetic polymers with living proteins to create a self-repairing solar-cell technology whose efficiency will not degrade over time. Today solar panels are available using a wide variety of materials whose prices are set according to the efficiencies obtained. For instance, the highest achieved efficiencies to date (as high as 25 percent) come from expensive multi-band gallium arsenide (GaAs) solar cells, which are only affordable by military and space applications. Next in efficiency comes pure crystalline silicon solar cells (about 15 percent efficient), then amorphous silicon (about 10 percent) followed by thin-film polymer-based solar panels, which are the lowest in both cost and efficiency (as low as 5 percent)...

#MATERIALS: "Phosphorescence boosts solid-state lighting"

Switching to purely organic phosphorescent emitters could drastically cut the cost of solid-state lighting panels, according to a team of researchers at the University of Michigan. Look for solid-state lighting (SSL) to replace incandescent and even compact fluorescent tubes over the next seven years. R. Colin Johnson @NextGenLog


Organic phosphors developed at the University of Michigan could one day lead to cheaper organic light-emitting diodes. Here, they glow in blue and orange when triggered by ultraviolet light. Credit: Marcin Szczepanski, U-M College of Engineering.

Here is what my EETimes story says about this solid-state lighting breakthrough: A University of Michigan team claims to have found the first example of a purely organic—and thus ultra-cheap—compound that can compete with an metal-doped emitters in terms of brightness and color tuning capability. Unlike fluorescence, a phosphorescent material does not immediately re-emit the radiation it absorbs, but rather continues to glow for up to several hours after the original excitation—a property that has previously been seen only in compounds doped with metals, called organometallics. However, these new metal-free organic compounds developed at the University of Michigan, which appear white in visible light, radiate blue, green, yellow and orange after absorbing ultraviolet light.

#NANOTECH: "Nanogenerators to Enable Battery-Free Handhelds"

Forget super-sizing. Nano-sizing is the future of energy harvesters, according to researchers who claim to have mathematical proof that battery-free electronic devices can be powered by mechanical energy from vehicle vibrations to body movements. Look for battery-free mobile devices by the end of the decade. R. Colin Johnson @NextGenLog


Northwestern University researchers fabricated a micro-electro-mechanical system (MEMS) to test their piezoelectric nanowires. (Source: Northwestern University)

Here is what my Smarter Technology story says about battery-free mobile devices: Energy harvesting today is confined to a few niche applications, such as powering wireless sensor networks in remote areas where it is too expensive to send out crews to constantly be replacing batteries. However, by nano-sizing the working element in these energy harvesters, Northwestern University researchers claim their efficiency can be improved enough to enable battery-free mobile electronics.

#MEMS: "Disposable Lab-on-a-Chip Cures Diagnostic Debacle"

For over a decade, the laboratory on-a-chip has been touted as a solution to world-health problems, promising to provide affordable medical diagnostics even in remote areas. Unfortunately, their cost has never been reduced enough to realize the dream—until now. Look for disposable lab-on-a-chip technologies to greatly expand the number of medical diagnostics that can be performed, like home pregnancy tests, without a prescription. R. Colin Johnson @NextGenLog


Purdue University researchers have invented an inexpensive paper lab-on-chip using microfluidics to flow a patient sample to functionalized dots that glow for rapid medical diagnostics and chemical analysis. (Source: Purdue University)

Researchers at Purdue University's Birck Nanotechnology Center have created a dirt-cheap lab-on-a-chip technology that harnesses microfluidics to instantly diagnose medical conditions. The "labs" are inexpensive enough to be thrown away after use...instead of fabricating microfluidic channels on silicon or glass substrates with semiconductor equipment, uses lasers to make the tiny channels on cheap paper substrates. The result is a device that can test for dozens of maladies simultaneously, and yet it is inexpensive enough to throw away after a single use...

#CHIPS: "Can Touch-Screen Tablets Revive the DRAM Market?"

Touch-screen tablets could help resuscitate the DRAM market in 2011 and beyond if only three caveats can be avoided. Look for touch-screen tablets to become the leading market indicator for component integration success for the next five years. R. Colin Johnson @NextGenLog


DRAM sales for touchscreen tablets is rising quickly, from just 37.8 million gigabits in 2010 to a high of 3.5 billion gigabits in 2014, according to IHS iSuppli.

Here is what my Smarter Technology story says about DRAM and touch-screen tablets: The market for dynamic random access memory (DRAM) revived in 2010 from recessionary lows, but price-per-unit drops are causing analysts to predict an anomaly in 2011—depressed earnings despite growth in unit sales. DRAM exploded in 2010, increasing by 77 percent over the recession years, according to IHS' iSuppli Corp. (El Segundo, Calif.). Unit sales growth will continue in 2011, but declining prices-per-unit will likely depress DRAM revenues overall. However, touch-screen tablets will likely mitigate the overall dip in DRAM revenue by virtue of rising sales of low-power "mobile" DRAM, whose price has remained stable compared with "commodity" DRAM...

The high crystal quality of III-V nanoneedles grown on silicon are enabling development of practical silicon-based optoelectronics .

Here is what my EETimes story says about integrated silicon optics: Scientists have long been interested in integrating lasers onto silicon to enable on-chip communications using light instead of electrons, which would lead to faster communication and increased bandwidth. But, unfortunately, there is a lattice mismatch between silicon and the traditional III-V materials used to craft semiconductor lasers. Now, researchers at the University of California at Berkeley claim to have surmounted that obstacle by growing indium-gallium-arsenide nano-pillars vertically. The researchers claim their technique is adaptable to mass production of robust on-chip structures for optical interconnects, field emitters, nonlinear optical signal generation, sensors, solar cells, displays and nano-fluidics...

Look for a lively match pitting man against machine on Feb. 14-16. R. Colin Johnson @NextGenLog


Watson's father-figure, David Ferrucci, is principal investigator for IBM's DeepQA architecture.

The grand prize of $1 million goes to the winner, with second place earning of $300,000 and third place of $200,000. Instead of shipping Watson to Hollywood, this special edition of Jeopardy was taped last month at IBM's
 T.J. Watson Research Lab, where a mock-up of the original Jeopardy studio was 
constructed.


In trial Jeopardy matches with champions Ken Jennings and Brad Rutter, Watson (center) beat the humans.

Watson was built from the ground up to be adaptable to the kind of business applications for which IBM is famous. Unlike chess-playing Deep Blue, Jeopardy-playing Watson runs on a cluster of 90 commercially available Power 750 servers with 
2,880 Power 7 cores and 500Gbytes per second throughput.


John Kelly, director of IBM Research, claims that grand challenges provide focus for multidisciplinary efforts.

During trial sessions, Watson beat the humans—just barely--but you'll have to tune into Jeopardy to see who wins in the real contest. Check local listings on Feb. 14-16.
