Comcast gets serious about DOCSIS 3.0 rollouts


Alright Minneapolis, you've had your fun. Now it's time for another swath of Comcast markets to indulge in the lavish joys that only DOCSIS 3.0 can provide. For those unaware, the aforesaid technology enables 50Mbps internet to be delivered over the cable company's infrastructure, which brings it up to speed (ahem) with offerings by fiber-based carriers Verizon and AT&T. In the next few weeks, the DOCSIS 3.0-based "Extreme 50" option will bring 50Mbps down / 5Mbps up to subscribers in parts of New England, Philadelphia and New Jersey. Better still, the company announced its intentions to bring the $139.95 per month service to ten other big markets where it will reach "about 10 million homes and businesses in the next few months." Oh, and if that's just too much intarwebz for you to handle, an "Ultra" 22Mbps downstream service will be available for $62.95 per month.

Photonic breakthrough could mean 60x faster internet speeds

Every so often, we get wind of some new "breakthrough" from a few guys / gals in a lab that promises to simply revolutionize the web. A team from the University of Sydney is the latest bunch to do so, claiming that a piece of scratched glass (or a Photonic Integrated Circuit, if we're being proper) could enable internet speeds 60 times faster than "current Australian networks." Essentially, the "circuit uses the scratch as a guide or a switching path for information," and the resulting product is "photonic technology that has terabit per second capacity." Call us when you folks get everything ironed out -- we'll be over at Sigbritt Löthberg's house.

Hydraulic transmission gives engines, wallets a break


Another day, another potential find to avoid the imminent fuel crisis. On the docket today is Ernie Brookins' hybrid drive system, which "captures, compresses, and stores wasted drive-train energy produced when a vehicle's engine is running." Ernie here has concocted a hydraulic transmission that can reportedly power vehicles without the engine running all of the time, and he expects the solution to save motorists around 50-percent in fuel costs. Better still, the contraption could theoretically work on nearly any vehicle -- from school buses to grain trucks to high-octane Power Wheel Jeeps. As these things seem to always go, the project has hit a roadblock without a source of funding, so if any VCs out there are looking for a somewhat solid place to shove $250,000, give this man a ring.

Tesla's original transmission maker sues for back payment


The drama surrounding the Tesla Roadster's transmission and the company's attempts to build a system that can transmit power from the motor to the wheels without breaking under the strain took another strange twist today, with the revelation the that first supplier Tesla contracted to design the part is suing the company for $5.6M. Magna Powertrain USA says Tesla hired it to develop a two-speed transmission in September 2006, and when things fell behind schedule, Tesla canceled the contract and walked away without paying. Saucy! Of course, problems with the proposed two-speed transmission are why Tesla plans to ship early production Roadsters with "temporary" one-speed units and swap them out later, but there's no word on where the two-speed versions are going to come from apart from Tesla saying "We need to have more control over our fate and manage the process in house." Sure, sure, just as long as we get one for "testing," okay?

Super 3G hits 250Mbps downlink in NTT DoCoMo field test


Just think -- this time next year, we'll all look back at this milestone and wonder how on Earth we thought it was impressive. For now, however, we wouldn't blame you for high-fiving everyone around, as NTT DoCoMo has stretched the boundaries again with a recent Super 3G field test. Reportedly, the outfit was able to record "a downlink transmission rate of 250Mbps over a high-speed wireless network in an outdoor test of an experimental Super 3G system," and while it's not quite the 300Mbps we'd heard about before, you won't find us kvetching. If all goes to plan, the firm is hoping to "complete development of the technologies required for the eventual launch of a Super 3G network" by 2009, but who knows how long we Americans will have to wait to indulge after that.

Tesla clarifies "temporary transmissions," say they're slower, not going to fail


We'd heard that problems with the Tesla Roadster's transmission were going to lead the company to ship the cars with "temporary" transmissions, but our friends over at AutoblogGreen were recently contacted by Tesla and told that while the company is indeed considering shipping cars with a different tranny than originally planned, they won't be designed to fail, as we'd originally heard. Rather, it'll be a single-speed transmission that won't allow the all-electric hot rod to run as fast as the planned two-speed version. Tesla still plans to swap out the units for the real deal when they're finally strong enough to handle the electric's massive torque, but at least now when Tesla owners are stranded by the side of the road they'll just need an extension cord, not a whole new transmission.

Tesla to deliver Roadsters with "temporary" transmissions?


The Tesla Roadster was supposed to be out before the end of the year, but it looks like the wicked-fast electric car won't make that target -- apparently the company is having problems finding a transmission strong enough to handle gear shifts while the car remains at full torque. The problem is somewhat unique to electric cars, and Tesla's got two different suppliers scrambling to find a solution -- but in the meantime, the company is considering providing vehicles outfitted with "temporary" transmissions that are basically guaranteed to fail after a few thousand miles. The first of these has already been built for company chairman Elon Musk, and Tesla is deciding whether to start shipping cars with the temporary units to other customers and then replacing them when a final transmission becomes available. That's the price of progress, we suppose, but something tells us quite a few people would rather just wait for the final product.

Fuji Television demonstrates visible light communications system


It's not like visible light communications is the new kid on the block or anything, but Fuji Television was busy showcasing a new flavor of the technology at Inter BEE 2007 that could assist deaf / hearing impaired individuals when watching TV. In the demonstration, a LED-backlit LCD TV displayed content while simultaneously beaming out information sans wires to a nearby PDA; the handheld was able to receive the textual data and display words to accompany the on-screen action. Not surprisingly, the communications system was developed by NEC, and it even supported selective distribution in order to transmit the correct information to the appropriate individual. No mention was made of an expected commercialization date, but feel free to check out a couple more shots of the setup after the break.

ONFi 2.0 sets the stage for 133MB/sec NAND performance

Flash memory just keeps getting bigger, faster and more irresistible -- and that's just the way we like it. Now, the Open NAND Flash Interface (ONFi) working group is announcing the availability of the 0.9 draft of the ONFi 2.0 specification to member companies, which is a tell-tale sign that the updated spec will be officially loosed in just two months. What's important here is the newly defined NAND interface, which promises to deliver up to 133MB/second compared to the 50MB/second that the legacy NAND interface is limited to. As if that weren't enough to get you all jazzed up, ONFi 2.0 will also be backwards compatible, and infrastructure is reportedly in place to "reach 400MB/second in the third-generation." And just think, soon you'll be chuckling at yourself for asserting that 133MB/sec was "quick" -- onwards and upwards, we say.

Internet2 operators set new internet speed record

We all know that data transmission records don't hang around too long these days, but for operators of the Internet2 network, the final "official record" may have just been set. At the Internet2 consortium's spring meeting, it was announced that officials "sent data at 7.67-gigabits per second using standard communications protocols," but crushed even that milestone 24 hours later by achieving 9.08Gbps with IPv6 protocols. Notably, the data had to travel a whopping 20,000 or so miles roundtrip, and it's being suggested that the newest record may be there awhile, considering the theoretical 10Gbps limit on Internet2 transmissions and the requirement for new records to sustain "a ten-percent improvement for recognition." The best bit, however, is the mention of a "a new network with a capacity of 100Gbps," which could see a full-blown DVD shot practically around the globe "within in a few seconds."

Radiofrequency treatment curbs asthma attacks

Sure, there's quite a few way to circumvent the effects of asthma, but a new development coming out of McMaster University in Canada suggests that radiofrequency treatment can actually curb the amount of asthma attacks suffered by asthmatics. The device, which "uses radio waves to heat the muscle lining of patients' airways," is used to administer a trio of sessions, and while the actual root cause is still unknown, it seems to cause a reduction in the smooth muscle lining the airways, subsequently making breathing less of a chore. The probe isn't the most comfortable, however, as it must first make its way through your nose or mouth in order to reach the lung airways, after which the tip is "heated using radio waves." The procedure is known as bronchial thermoplasty, and while the funding company (Asthmatx) has yet to elicit a thumbs-up from the FDA, it could certainly become a viable alternative for asthma sufferers. It's about time these free-flying transmissions made up for the harm they've caused, eh?

Alcatel-Lucent blows past data transmission record: 25.6Tbps

Data transmission records were just made to be shattered, as we've seen the benchmark go from 2.56- to 14- and now to 25.6-terabits per second within a year (and five days, but who's counting?). The momentary record holder this time around is Alcatel-Lucent, which "successfully transmitted a world record 25.6Tbps of optical data over a single fiber strand' using 160 WDM channels. In case you were wondering, that's enough speed to send about 600 DVDs worth of information to your buddy in one single second, after which you'd likely destroy any and all functionality his / her computer previously had before the bombardment. Now, what's it cost to run one or two of these pipes to Sealand?

Matsushita demonstrates data beaming with visible light


Infrared hasn't exactly taken the wireless data transfer world by storm, and while it seems to still flank the sides of modern smartphones and the occasional laptop, we can't exactly recall the last time we found it particularly useful in a public setting. Matsushita is out to solve the data beaming quandary, and it's looking to add a little light to the situation all the while with a visible twist. The technology allows data to be beamed from transmitter to receiver via visible light, and aside from purportedly streaming information along at "optical fiber speeds," it can also pull double duty as an indoor lighting source if you're short on lamps. The firm is hoping to get the standard ratified soon, and ideally, would like to see kiosks set up to beam information onto consumer / client receivers by just walking up to the light source, pairing up their device, and walking away happy. Additionally, this system could have a leg up on other wireless alternatives in sensitive areas such as hospitals, as the Visible Light Communications (VLC) creation won't interfere with pulse-makers and other medical equipment. Now, how long before this stuff hits the handset market?
