Storing Hydrogen At Room Temperature 152

cylonlover writes "Hydrogen storage, along with hydrogen production and the lack of infrastructure, remains a major stumbling block in efforts to usher in hydrogen as a replacement for hydrocarbon-based fuels in cars, trucks and even homes. But with the multiple advantages hydrogen offers, developing hydrogen storage solutions has been the focus of a great deal of research. Now an MIT-led research team has demonstrated a method that could allow hydrogen to be stored inexpensively at room temperature."

Self-Powered Microbial Fuel Cell Produces Hydrogen 58

donberryman writes "Researchers from Penn State have shown how microbial fuel cells can produce hydrogen without the need for an external source of electricity to power the process. It uses reverse-electrodialysis to capture energy from the difference in salinity between salt water and freshwater (abstract). Study co-author Bruce Logan explained the significance of the work: 'The breakthrough here is that we do not need to use an electrical power source anymore to provide a little energy into the system. All we need to do is add some fresh water and some salt water and some membranes, and the electrical potential that is there can provide that power.'"

Nvidia's Kal-El Tegra Will Have Fifth "Companion Core" 98

Blacklaw writes with an article in Thinq about the upcoming quad-core Tegra chipset. Quoting the article: "Nvidia has released a few technical details of its upcoming 'Kal-El' Tegra processor, including a secret it's done well to keep under its hat thus far: it's a five-core, not four-core, chip." The fifth core will be clocked lower and is intended to let the system use little power without having to fully suspend. A few years ago Openmoko had a vaguely similar idea to include a microcontroller for low-resource idle tasks (e.g. GPS logging), but this design is superior since it should be more or less transparent to user space programs.

Ask Slashdot: Recovering Data From 20-Year-Old Diskettes? 375

First time accepted submitter Zilog writes "The end of the 3.5-inch floppy and the disappearance of associated drives showed to me the need to backup the tens of diskettes that accompanied my youth. Carefully preserved, these diskettes have proved readable for the most part — while some are approaching 20 years old. However, some diskettes have shown surface defects in areas with compressed archives (zip). Any ideas on how to recover (as much as possible) these bad sectors?"

British Govt Debates Swapping Printers For iPads 237

An anonymous reader writes "The British government is examining whether it could save money by getting rid of its printers and giving civil servants free iPads instead. The head of the UK government skunkworks told silicon.com that if he got rid of all of a major government department's printers and gave staff iPads, the savings on printing costs would pay for the tablets in less than 18 months. The UK parliament has already let tablets into the debating chamber, with politicians already starting to choose to use tablets rather than bundles of papers in debates."

SMK Toughens Up Those Tiny Micro-USB Connections 137

An anonymous reader writes "If a gadget ships with a micro-USB port, I see it as a plus because it isn't proprietary — meaning I can easily and cheaply buy replacement cables. But the micro-USB ports aren't the strongest connectors in the world, so if the gadget is expensive (a smartphone) and you accidentally bust the port, you're in trouble. And that's easily done. Japanese manufacturer SMK may have fixed the problem, though, with a new double-strong connector design. They started producing them on Friday, and at an output of 500,000 a month, hopefully they'll be shipping with most new gadgets before long."

MIT's $1,000 House Challenge Yields Results 203

An anonymous reader writes "MIT's $1k House Project is an extraordinary challenge to provide safe and healthy homes for the world's burgeoning population. The Pinwheel House (PDF), a student project which helped serve as a catalyst for the challenge, has been completed in China by architect Ying chee Chui. Students have come up with a dozen or so designs to meet the challenge and improve living conditions for not just emerging economies but larger nations as well."

Intel's RISC-y Business 225

Esther Schindler writes "With the Xeon 7600 line, Intel is finally using the 'R' word: RISC. With the new chips, Intel is targeting the mission-critical market dominated by Sun SPARC and IBM Power, a first. Can the Xeon E7 processor deliver Intel's final blow to the RISC market, which includes its own Itanium? 'With the launch of the E7 earlier this year, it seemed Intel was finally ready to make its final push, calling out RISC by name. "The days of IT organizations being forced to deploy expensive, closed RISC architectures for mission-critical applications are nearing an end," said Kirk Skaugen, vice president and general manager of Intel's Data Center Group, in a statement announcing the E7 line. Bold words.' Andy Patrizio interviews several experts; what do you think?"

Arduino Goes ARM 144

mikejuk writes "The whole world seems to be going in ARM's direction. The latest version of Windows 8 will run on ARM processors, Raspberry Pi is a $25 ARM based machine and now the open source Arduino platform has a new member — the ARM-based Arduino Due announced at the Maker Faire in New York. The Due makes use of Atmel's SAM3U ARM-based process, which supports 32-bit instructions and runs at 96Mhz. The Due will have 256KB of Flash, 50KB of SRAM, five SPI buses, two I2C interfaces, five serial ports, 16 12-bit analog inputs and more. This is much more powerful than the current Uno or Mega. However, it's not all gain — the 3.3V operating voltage and the different I/O ports are going to create some compatibility problems. Perhaps Intel should start to worry about the lower end of the processor world."

Siemens To Exit Nuclear Power Business 400

jones_supa wrote in with a link about the future of nuclear power in Germany. The story reads: "German industrial giant Siemens is turning the page on nuclear energy, the group's CEO Peter Löscher told the weekly Der Spiegel in an interview published on Sunday. The group's decision to withdraw from the nuclear industry reflects 'the very clear stance taken by Germany's society and political leadership.' Along with abandoning nuclear power, Germany wants to boost the share of the country's power needs generated by renewable energies to 35% by 2020 from 17% at present."

Thin Film Transforms Any Surface Into Touchscreen 81

kkleiner writes "Open up a cardboard tube, roll out a transparent film just millimeters thick, apply it on a flat object and *tada* you've got an interactive touch surface. Cambridge-based Visual Planet just launched its new massive-sized multitouch thin film drivers so you can create touchscreens from 30 to 167 inches in size! Their touchfoil is a transparent nanowire embedded polymer capable of sensing the touch of a finger, or even pressure from wind and translating that to a computer interface. It works on glass, wood, and other non-conductive surfaces."

Artificial Blood Vessels Created On a 3D Printer 33

rallymatte writes "A team at Fraunhofer Institute in Germany has managed to create artificial blood vessels with a 3D printer that may come to be used for transplants of lab-created organs. From the article: 'To print something as small and complex as a blood vessel, the scientists combined the 3D printing technology with two-photon polymerisation — shining intense laser beams onto the material to stimulate the molecules in a very small focus point.'"

Printing a Building 112

RedEaredSlider writes "Researchers at the Massachusetts Institute of Technology are trying to push 3-D printing technology even further. Their goals: create whole working machines and perhaps even buildings. Thus far, 3D printing has been used to make shapes of plastic or metal that can be assembled later. These folks want to change that. One idea is to use concrete in a novel way: 'Not only would it be possible to create fanciful, organic-looking shapes that would be difficult or impossible using molds, but the technique could also allow the properties of the concrete itself to vary continuously, producing structures that are both lighter and stronger than conventional concrete. To illustrate this, Keating uses the example of a palm tree compared to a typical structural column. In a concrete column, the properties of the material are constant, resulting in a very heavy structure. But a palm tree’s trunk varies: denser at the outside and lighter toward the center. As part of his thesis research, he has already made sections of concrete with the same kind of variations of density.'"

Intel Experimental Processor Runs On Solar Power 104

An anonymous reader writes "For the IDF keynote, Intel showed an experimental processor that is solar powered (incandescent light shining on a solar panel). The whole computer itself still runs on regular power; only the processor itself is solar. From the article: 'The concept processor, code-named Claremont, can run light workloads on solar power by dropping energy consumption to under 10 milliwatts, said Justin Rattner, chief technology officer at Intel, during a keynote address at the Intel Developer Forum in San Francisco. That is low enough to keep a chip running on a solar cell the size of a stamp.'"

Robot To Slowly Run Ironman Triathlon Course 71

itwbennett writes "A robot designed by Panasonic will be running the course of this year's Ironman World Championship triathlon next month. But don't expect it to win. The diminutive robot won't even be competing in the actual race. It will start the Ironman course Oct. 24 and finish in about a week (168 hours), according to its designer. 'Evolta's height is just one-tenth of a grown man, so we figured out that it would take it 10 times more time,' Panasonic design engineer Tomotaka Takahashi told Reuters."

MIT Researchers Create New Tiny Energy Harvester 101

RogerRoast writes "Researchers at MIT have designed a device the size of a U.S. quarter that harvests energy from low-frequency vibrations, such as those that might be felt along a pipeline or bridge. The tiny energy harvester — known technically as a microelectromechanical system, or MEMS — picks up a wider range of vibrations than current designs, and is able to generate 100 times the power of devices of similar size."

Ask Slashdot: Clusters On the Cheap? 264

First time accepted submitter serviscope_minor writes "A friend of mine has recently started a research group. As usual with these things, she is on a shoestring budget and has computational demands. The computational task is very parallel (but implementing it on GPUs is an open research problem and not the topic of research), and very CPU bound. Can slashdotters advise on a practical way of getting really high bang for buck? The budget is about £4000 (excluding VAT/sales tax), though it is likely that the system will be expanded later. The computers will probably end up running a boring Linux distro and Sun GridEngine to manage batch processing (with home directories shared over NFS)."
