waderoush writes "There are plenty of waste-to-energy plants around the US, but most of them simply burn the waste, dumping carbon dioxide into the atmosphere. Gasification technology, by contrast, converts nearly all of the waste into gases like hydrogen and carbon monoxide that can be used to run generators and furnaces. The problem is that most gasification facilities are factory-sized. Now a startup outside Boston has built a combination shredder-dryer-pelletizer-gasifier that fits into 30-by-8-by-8-foot shipping container. The so-called 'Green Energy Machine' can be backed up to a loading dock by truck, processing 3 tons of solid waste per day and putting out enough synthetic gas to run a 120-kilowatt generator or a 240-kilowatt-equivalent furnace. The makers say the machine can eliminate 540 tons of carbon emissions per year, in large part by reducing the amount of waste that goes to methane-generating landfills."

Interesting, even though the really good stuff is presumably being kept under wraps." Relatedly, necro81 writes "The Inauguration of Barack Obama tomorrow is expected to put considerable stress on the cellphone network around Washington, DC. The expected crowd could top two million people, and many of them are expected to call, text, tweet, photo, and blog their way through the event. In response, the major wireless carriers in the area have spent millions of dollars upgrading their local networks and will bring in extra 'cells on wheels' (COWs) and 'cells on light trucks' (COLTs). They are also requesting that attendees limit their usage during the event, and avoid bandwidth-heavy activities — like uploading photos — until afterward."

holy_calamity writes "TechCrunch blogger Mike Arrington decided last year to invent a new class of low-cost internet tablet using open source hardware and software. The second prototype has been unveiled, sporting a 12-inch touchscreen powered by a Via Nano processor, 1 GB of ram and a 4 GB flash drive. It runs a browser and nothing else on top of a custom Linux build. 'Resolution is 1024×768, which means the vast majority of websites are viewed in full width without scrolling. The device also has wifi, an accelerometer (so when you turn the screen on its side you can view more of a web page), a camera and a four cell battery.'"

Michael Pyne sends in an article published at Reason Online 13 years ago, dismantling the entrenched myth that the Dvorak keyboard layout is a superior technology to QWERTY. The odd thing is that this 13-year-old article recaps research (refereed and published in a respected economics journal) 19 years ago. While we have discussed Dvorak many times over the years, I don't believe we have dug into this convincing-sounding refutation of the Dvorak mythology. The article is in the context of arguing against the conventional wisdom of "first mover advantage" — that the first product to market gains a large entrenchment benefit, such as VHS vs. Beta, MS-DOS vs. anything, etc. It's very much a pro-markets piece.

suraj.sun recommends a CNet post giving details of a still little-known energy technology: the ground source heat pump or geo-exchange system. This is distinct from so-called geothermal energy, which taps the heat in the earth to provide energy. Geo-exchange is suitable in scale for small industry — the article describes one commercial re-development of an old mill into apartment and commercial space that put in a geo-exchange at about half the cost of traditional fossil fuel-based alternatives. Even some individual homeowners are opting for this green method of heating and cooling, at a premium in price of about 50 percent (but costs are very much per-project, largely because drilling is involved). "Rather than use underground heat, geothermal heat pumps attached to buildings capitalize on the steady temperature of the ground or deep water wells. In effect, they treat the Earth like a giant energy savings bank, depositing or withdrawing heat depending on the time of year. "

An anonymous reader writes "Robot innovation continued its relentless advances during 2008. SingularityHub has a showcase of the best robot videos of the past year. These robot videos are really amazing, and they show just how far we have come in the field of robotics in recent years." The videos include toy robots, robot musicians (which we've discussed in the past), modular robots that work together to move around, robots doing synchronized martial arts, the BigDog robot that can walk on almost any type of terrain, and robot soccer. We've also recently talked about a couple of robots that will bring you beer.

grunaura writes "South Korean researchers have devised a way to create graphene sheets one centimeter square using a hydrocarbon vapor on heated nickel. It's touted as being more efficient than the current process where graphene sheets are pressed, and there is evidence that 'the quality of graphene grown by chemical vapour deposition is as high as mechanically cleaved graphene.' Graphene is relatively new, but not to Slashdot. This round of news highlighting the technology focuses on the bendable nature of graphene sheets, as opposed to the memory applications or capacitive properties discussed here previously. These films are the closest we have come to superconductors at room temperature."

remove office writes "I recently discovered that Belkin's lead online sales rep, Michael Bayard, has been secretly paying internet users to review his company's products favorably on Amazon.com and other websites like Newegg, whether or not they've ever used the devices. Bayard instructed the people he was paying to 'Write as if you own the product and are using it... Mark any other negative reviews as "not helpful" once you post yours.' Ironically, he was using Amazon's own Mechanical Turk service to hire his fraudsters. Did he honestly think he wouldn't get caught? Are Slashdotters aware of other examples of other such blatant astroturfing on behalf of a large tech company like Belkin?"

marciot writes "I live in a condominium where I get interference from my neighbors' WiFi. I understand that 1, 6 and 11 are the only non-overlapping WiFi channels, but how does this translate into real-life best practices? When you must overlap, is there a 'good' way to do it? With nine access points, for example, is it better to have three APs each on 1, 6 and 11, so that each completely overlaps with only two others? Or is it best to distribute those APs across nine channels such that they only partially overlap others (but potentially overlap more APs in total)? Do use patterns affect interference? For example, is it best to overlap a channel with multiple APs that rarely transfers data, or to share a channel with one person who downloads torrents 24/7? Does maximum data rate affect interference or robustness to interference? I found out by accident that setting my access point to '802.11b only' mode appeared to give me a vastly more reliable connection that leaving it in 'mixed 802.11b/g.' Is this a fluke? Or does transmitting at 10 Mbps when everyone else is using 54 Mbps (for their 3 Mbps DSL pipes!) give you a true advantage?"

AnInkle writes "Two months after acknowledging that their flagship 1.5TB Barracuda 7200.11s could hang while streaming video or during low-speed file transfers, Seagate again faces a swell of complaints about more drives failing just months after purchase. Again, The Tech Report pursued the matter until they received a response acknowledging the bricking issue. Seagate says they've isolated a 'potential firmware issue.' They say there's 'no data loss associated with this issue, and the data still resides on the drive;' however, 'the data on the hard drives may become inaccessible to the user when the host system is powered on.' If users don't like the idea of an expensive data-laden paperweight, Seagate is offering a firmware upgrade to address the matter, as well as data recovery services if needed. By offering free data recovery, Seagate seems to be trying to head off what could become a PR nightmare that may affect several models under both the Seagate and Maxtor brands."

snydeq writes "Texas-based Saxon Innovations has filed a complaint with the US International Trade Commission to bar six companies — including Research in Motion, Palm, and Nokia — from importing handheld devices into the US. At issue are three patents that Saxon purchased in July 2007; a patent for keypad monitor with keypad activity-based activation; a patent for an apparatus and method for disabling interrupt marks in processors or the like; and a patent for a device and method for interprocessor communication by using mailboxes owned by processor devices. Saxon, with five employees, purchased about 180 US patents formerly owned by Advanced Micro Devices or Legerity in 2007, according to its ITC complaint."

An anonymous reader writes to tell us that a company has demonstrated a new form of wireless communication that uses light instead of radio waves. "Its inventor, St. Cloud resident John Pederson, says visible-light embedded wireless data communication is the next step in the evolution of wireless communications, one that will expand the possibilities in phone and computer use. The connection provides Web access with almost no wiring, better security and with speeds more than eight times faster than cable."

Visceralini writes "NVIDIA is launching yet another high-end 3D graphics offering, an optimized version of their top shelf GeForce GTX 280 single GPU card, dubbed the GeForce GTX 285. This new GeForce is a 55nm die-shrunk version of the legacy GTX 280 with lower power consumption characteristics that don't require an 8-pin PCI Express connector, rather just a pair of more standard 6-pin plugs. Performance metrics are shown here in a number of the latest game titles including Fallout 3, Left 4 Dead, Far Cry 2 and Mirror's Edge. The new GTX 285 is about on par or slightly faster than a GTX 280 but with less power draw and some room for overclocking over the reference design."

An anonymous reader writes "Researchers have developed a way to network household and commercial fridges together in a distributed peer-to-peer fashion that lets them 'negotiate' with each other on the best time to consume electricity. A retrofittable controller is attached to each fridge and then a temperature profile is built around the unit. The controller enables communication between other fridges on the network and also the power source. It enables fridges to work together to decide when to cool down, and thus consume power, based on how much surplus power will be available, and to anticipate power shortages and change their running schedules accordingly to use as little power as possible during these times."

snydeq writes "InfoWorld's Logan Harbaugh follows up his '10 IT Power-Saving Myths Debunked' to argue in favor of using DC power in the datacenter. The practice — viewed as a somewhat crackpot means for reducing wasteful conversions in the datacenter just a few short years ago — has gained traction to the point where server vendors such as HP, IBM, and Sun are making DC power supplies available in their server wares. Meanwhile, Panduit and other companies are working to bring down another barrier for DC to the datacenter: a standardized 400-VDC connector and cabling solution. And with GE working to list 600-VDC circuit breakers with the Underwriters Labs, DC's promise of reduced conversion waste could soon be commonly realized."

ThinSkin writes "Slashdot readers may remember an article regarding ExtremeTech's Loyd Case's experiences with solar power for the home after one month of usage. During that time six months ago, it sure seemed like a great deal, but the tables have turned significantly once winter approached. While it's no surprise solar power generation is expected to dwindle during the winter, Loyd compares solar power data of the last six months to determine if solar power is still worth the time and money."

An anonymous reader writes "Sony's stand at CES had a small area set aside for flexible OLED screens, along with three mock-ups of possible OLED devices (including one stunning ultra-portable with no hinge and a single display for both screen and keyboard). There was also a working OLED screen being bent back and forth while playing a video clip. Does this mean roll-up, low-power colour screens will soon hit the market? Not unless OLED prices come down — Sony's stunning XEL-1 OLED TV costs $2,500, but only has an 11in screen ..."
