Dean Kamen unveils revamped bionic arm and water machine, LED light bulb powered by Cree
Segway inventor Dean Kamen just stole the show at TEDMED 2010, with both a far-reaching lecture on how technology can save the developing world, and a peek at his latest projects. We'll spare you the wave of guilt for now and get right to the cool stuff, like the latest rendition of his Luke prosthetic arm and Slingshot water machine. Dean admitted he's having difficulty finding companies interested in manufacturing the former, but it's looking snazzier than when it last grabbed Stephen Colbert, with components like this shoulder piece printed out of titanium in a custom 3D printer, and it's slated to look like this. The Slingshot's seeing even more action, as Dean and company have pulled it out of the ugly box into these svelte tubes, and finally has a distribution deal (with Coca-Cola, of all companies) to bring the clean-water-from-any-source machines to developing countries in trials early next year. Last but not least, the man's got a product you might be able to afford for your home. In the quest for an item for his FIRST young engineers to sell -- a la Girl Scout cookies -- he tapped LED manufacturer Cree to produce an 450 lumen light bulb that draws just 7 watts and will retail for about $25 door-to-door. In case you're wondering, that's cheaper and more efficient than most any lamp we've seen before. Dean says they've already produced several hundred thousand of the bulbs thanks to a surprise $3 million investment from Google, and plan to have them in the hands of every FIRST kid soon. Keep on fighting the good fight, Dean. %Gallery-106215%
GE closes last US factory making incandescent light bulbs
There may still be plenty of competition among potential successors to the incandescent light bulb, but there's little question that the traditional light bulb is on the way out -- a fact now further backed up by GE's closing of the last major factory making the bulbs in the US. GE had apparently considered a $40 million investment to retrofit the plant -- located in Winchester, Virginia, and employing some 200 workers -- to manufacture compact fluorescent light bulbs, but it says that bulbs made at the plant would have cost 50 percent more than ones from China, which is where the vast majority of CFLs are made. Of course, that shift hardly happened overnight -- be sure to hit up the Washington Post article linked below for a brief history of what led to this point, and a closer look at the plant itself.
Swirly CFLs relax a little bit, get kind of cute in the process
We never really had a problem with traditional CFL design, but it's always nice to have options when you're looking for new ways to decorate. London-based outfit Plumen has bent the usual coil shape into a more abstract pattern that we're sure will fit perfectly in our quirkily stark / offbeat loft uptown. The Plumen 001 model shown here ships on October 5th in the UK for £20, or €30 in the rest of Europe, but mum's the word on a North American release. From the looks of their Flickr, there are even crazier shapes in the works, though. Hypnotic spinning bulb footage after the break.
Tea kettle concept almost boils your water with an incandescent light bulb
Incandescent light bulbs are definitely not in fashion these days (the last time we stepped inside Ikea we were greeted with their announcement that the company plans to stop selling them) because of their total lack of efficiency. Don't tell that to this concept for a tea kettle, however, which uses the wasted energy of the bulb (nearly 98 percent) to make water for your tea. Now, it doesn't actually bring it to a boil -- just to 194 degrees Fahrenheit -- but many tea enthusiasts will tell you that your water should be just off the boil anyhow. So there.
How nutritious is your light bulb? (in lumens, of course)
No joke -- starting mid-2011, US light bulbs will have nutrition facts of their own. Backed by Congress, the FTC has mandated that light bulbs carry the label at top, allowing buyers to clearly compare brightness, life expectancy and energy cost. Of course, many manufacturers call out these facts already, but hopefully this will keep the rest from confusing potency with power -- by advertising that a mid-range LED unit that slowly sips energy, for instance, is "equivalent to 40 watts."
Lite-On's Mobile Lamp LED bulb works even when the power is out
We hate to break it to you, but those LED light bulbs that are shaped like traditional light bulbs? It's all a lie. LEDs are naturally pretty small things, and while there might be dozens scattered about inside a bulb there's still plenty of empty space in there meant only to make the things about the same size as a good ol' incandescent. Lite-On, however, has found something to make use of that space: batteries. The company's Mobile Lamp bulb can stay on for up to two hours even after the power is turned off, effectively turning it into a flashlight. To switch the bulb on or off you simply touch the copper part while something conductive makes contact with the metal part on the bottom, which could be a lamp socket or just a finger, as shown in the brief video after the break. The bulbs are due to be out sometime next year and should be hugely popular in areas with unreliable power -- or with an abnormally high rate of magicians per-capita.
Nokero debuts rugged, rainproof N100 solar light bulb for developing worlds
Oh, sure -- the world has plenty of those ritzy LED light bulbs to choose from, but how's about using the ultimate light source to create... even more light! That's exactly what Nokero is setting out to accomplish with its N100, which is being christened the "world's first" solar light bulb. Designed specifically for use in developing nations where continual electricity is a mere pipe dream, this bulb is housed in an ultra-rugged, rainproof enclosure that can provide around four hours of light when fully charged; if you leave it in the sun all day, it'll harness enough juice to provide illumination for around two hours. The unit itself is constructed from impact resistant plastic and includes a foursome of solar panels, five LEDs and a replaceable, nickel metal hydride battery that's said to last two years. The company informed us that these will run you around $15 if purchased one at a time, though the goal is to sell 'em in bulk for around $6 apiece and have them delivered to rural parts of India, Africa and possibly District 9. Go on and get schooled by heading past the break and clicking play. %Gallery-94767%
Philips' new LED light bulbs are brighter, more efficient, not cheap
Philips' Master LED bulbs may well have been forgotten in the US -- as far as we can tell, they never showed up for that hot date last July -- but it's hard to be miffed when the company's new bulbs, dubbed EnduraLED, are four times as bright. Due in the fourth quarter of the year, the 60W equivalent at left sucks down only 12 watts of electricity but emits a reported 806 lumens of soft white light -- a ratio green enough to save the world, Philips claims, if only you'll buy in. Problem is, people's generosity typically depends on price, and a company rep told us we'll shell out around $60 per bulb when the shiny silver socketables ship. Mind you, that's just an initial figure, but until we hear different we'll be going to Home Depot for our lighting needs, thank you very much. Press release after the break.
The Home Depot takes LED lighting mainstream with $20 bulbs
Slowly but surely, LED light bulbs have been getting brighter and more efficient, but price has always been a major factor staying their adoption. Back in 2007, a single 308 lumen bulb cost $65, and the more things changed, the more they've stayed the same. Now, out of the blue, The Home Depot has stepped forward with a cost-effective alternative. For $20, the new EcoSmart LED bulb promises a 429 lumen, 40W equivalent with a 50,000 hour expected lifetime, making it cheaper and nearly as powerful as the 450 lumen, $40-50 design industry heavyweight GE unveiled last month. Best of all, it's already available for purchase (though backordered) at our source link. Honestly, we're starting to wonder what the catch is. PR after the break.
GE's LED light bulbs look cool, last forever, cost a lot
Citizens of the Earth, you're looking at the lightbulb of the future. In the coming years and decades our lives won't be illuminated by simple spheres or coils of white. Oh no; future bulbs will have cool fins and flares that make them look almost worth the $40 to $50 we'll pay for the things. That's what GE plans to ask for its Energy Smart LED bulb when it ships sometime in the next 12 months, and while that is a lot compared to the exiting options, look at the benefits: GE's bulbs will last a whopping 17 years when used four hours a day, and they give off light in all directions -- not focused in one spot like previous designs. But, most importantly, they're very efficient, using nine watts to give off the equivalent amount of light of a 40 watt incandescent bulb. That's 10 percent less than a 40 watt equivalent CFL, and there's no mercury or other toxic goop involved here either. It's the future, folks. Start saving. %Gallery-90389%
Nanofiber lighting promises to be better, safer than incandescent or CFL bulbs
Well, it looks like you can add another contender to the great light bulb debate -- a group of researchers from RTI International now says that nanofiber lighter is more efficient than incandescent light bulbs, and safer than compact fluorescents. The secret to that, it seems, is a combination of nanofiber-based reflectors and photoluminescent nanofibers (or PLN), which together are able to form a lighting device that pumps out more than 55 lumens of light output per electrical watt consumed. That's five times more efficient than a regular incandescent light bulb, and since there's no mercury, the researchers say it's far safer than CFL bulbs. What's more, it's also apparently able to produce more natural light than CFLs, although there's noticeably no mention of potential pricing -- they do say that the first products using nanofiber lighting could be available in three to five years, though.

Vu1 Corporation sees bright future for ESL light bulbs
Rivalries. Controversy. Government intervention. The life of a light bulb isn't easy these days, and it looks like things are about to get even more complicated. While CFLs and LEDs may now be fighting it out to replace traditional incandescent light bulbs, Seattle-based Vu1 Corporation says it has developed a new type of bulb that's better than either of 'em, and could hit the market by mid-2010. Making use of ESL technology (or electron stimulated luminescence), the new bulbs seem to be the cure-all many folks have been looking for, with them promising to provide a more natural light than CFLs or LEDs, turn on as quickly as an incandescent bulb, and eliminate some of the pesky problems associated with CFLs (like their use of mercury). According to the company, they'll also be about as efficient as CFLs, although they will cost about $20 a pop to begin with, which Vu1 says is comparable to a dimmable CFL reflector bulb. Some bold claims to be sure -- claims made even bolder by the must-see "documentary" after the break.
Crapgadget: "Oh yeah, they're totally serious" edition
Every so often, we come across a gadget (or five) that's so offensive, so absurd that we simply can't help but stick it in our back pocket and show it to the general public. Today, we're rounding up the worst of the worst once again, proving that there literally is no end to the spewing of gadget-related garbage that comes from unknown caverns in undisclosed corners of the universe. We mean, just listen to these products: "fried eggs night light," "Bic lighter spy camera," "hungry caterpillar USB hub," and "half-eaten chocolate mouse." Does those even sound like kit that any partially sane individual would purchase? No, no it doesn't. Have a gander while shaking your head furiously below, and feel free to drop a vote for the king of the crap while venting in comments below.

Brando credit card light bulb fills the void in your wallet... not your heart
Tailored to fit inside a vacant credit card slot -- let's face it, we've all got a bit more room in our wallets these days -- Brando's latest offering is an unfolding LED light tastefully shaped like a bulb. You might point out the irony of replacing cold hard cash with a cute yet limited trinket, but do you really expect such subtlety to stop the company that brought you the sliced bread wrist rest? We'll let you to come up with viable justifications for its existence, but do yourself the favor of going past the break for a snap of the little wonder flicked on, while we decide whether to file it under pointless sophistication or sophisticated pointlessness.
Study says LEDs are about as efficient as compact fluorescents, all things considered
As we've seen with the slight resurgence of new and improved incandescent light bulbs, the amount of energy used to actually light up the bulb isn't necessarily the whole measure of energy efficiency. There's also the small matter of producing the bulb, shipping it around the world, and eventually disposing of it. With that in mind, the Siemens Corporate Technology Centre for Eco Innovations conducted a study that compared regular compact fluorescents to LED lamps -- using one 25,000-hour LED lamp as a constant, compared to 2.5 10,000-hour compact fluorescents (and 25 1,000-hour incandescents). While it's still holding back on some of the finer details, the group did apparently find that LEDs are no more or no less energy efficient than compact fluorescents when the entire lifecycle of the bulb is taken into account, although it is quick to point out that LEDs should eventually win out as they become more efficient to produce.
Incandescent bulbs making a comeback, GE still launching new LED lights
On the eve of Christmas 2007, quite a few obituaries for incandescent light bulbs were penned. News was slow, time was short and Congress had just outlined a new energy plan that would essentially force these energy-wasting bulbs out by 2012. Now, however, legions of scientists are racing the clock to develop new incandescents that will still meet the upcoming guidelines, with a Deposition Sciences technology paving the way for a post-2012 model from Philips. Without drowning you in technobabble, let's just say that said tech has seen 50 percent efficiency gains in the lab, which is more than enough to please even the most outspoken tree hugger in Washington. In related news, GE has issued two more LED light bulbs: the 7-watt Energy Smart LED PAR20 and 10-watt LED PAR30. Both of 'em are aimed more at commercial customers than at actual homes, but you'll be hard pressed to find a better option for lighting up your makeshift basketball court.Read - Incandescent bulbs stage comebackRead - GE Energy Smart bulbs
Sharp's remote controlled LED light-bulbs generate seven-shades of smart
While you're replacing your household incandescent light-bulbs with LEDs in a bid to save energy and possibly cash (over the 40,000-hour lifespan) you might want to consider these remote-controlled lamps from Sharp. The DL-L60AV gives you on/off and dimming functions as well as the ability to adjust the light in seven shades of white to warm up or cool down the glow. Best of all, they screw into a standard E26 socket for a one-to-one exchange with your existing ocean warmers. The features of the remote control are still unclear (lighting zone support, range of operation, etc.) but it appears to work with multiple-lamps in parallel which is a nice touch. However, we'd like to see Sharp integrate a Z-Wave or ZigBee chipset so we could link these directly (without special wall-switches) into a tricked-out home automation and power managment system. The DL-series start at ¥3880 (about $40) for simple LED lights before hitting ¥7980 (about $82) for the fully-equipped DL-L60AV and begin shipping July 15th in Japan.
Ultra-powerful laser could make incandescent light bulbs more efficient
Look, LED light bulbs are fanciful, great for Ma Earth and a fine addition to any home, barber shop or underground fight club. But let's be honest -- even the guy that bikes through blizzards to get to work and wears garb that he grew in his basement isn't apt to shell out $120 a pop to have what's likely the most efficient light bulb American dollars can buy. Enter Chunlei Guo from the University of Rochester, who has helped discover a process which could morph a traditional incandescent light bulb into a beacon of burning light without using nearly as much energy as before. In fact, his usage of the femtosecond laser pulse -- which creates a "unique array of nano- and micro-scale structures on the surface of a regular tungsten filament" -- could enable a bulb to increase output efficiency in order to emit 100-watts worth of light while sucking down less than 60-watts of power. Per usual, there's no telling when this new hotness is likely to hit the commercial realm, but one's thing for sure: we bet GE's paying attention.[Via Physorg]
GeoBulb LED light bulb uses just eight watts, rings up at $120
Ah, progress. Right around two years ago, we spotted a LED-filled light bulb that used "just" nine watts and cost a staggering $65. Now, we've got yet another option that sucks down even less power and costs nearly twice as much. C. Crane Company has been working on its so-called GeoBulb for a solid three years now, but at long last the device is shipping to affluent homeowners and headstrong Earth lovers. The bulb can provide as much light as a traditional 60W incandescent with just 7.5W, and it features a 30,000 hour (10 years) lifespan with typical usage. Now, the hard part: choosing between cool, soft and warm white.[Via Times-Standard]
Philips Master LED light bulb set for US release in July
Philips has been hitting us with some out-there lighting concepts lately, but the company's Master LED light bulb is actually already on sale in Europe and is set to brighten up Stateside lives around July. The 40W-equivalent bulbs should run between $50 and $70, and expected lifetime is set at 45,000 hours -- just slightly more than a CFL's 10,000 or a standard bulb's 750 hours. The Master is certainly a damn sight nicer looking than the other mutant LED bulbs we've seen, but we'll see if consumers are ready to jump on another more-expensive-upfront lighting tech so soon after CFLs have hit the mainstream.[Via Core77]
