Energy Star 3.0 regulations set to impact TV designs
If you thought there was a row over the Energy Star 3.0 requirements for TVs, you haven't seen anything yet. Research firm iSuppli rightfully calls out some challenges for even the energy-miserly LCD TVs to duck under the numbers in the draft version of the Tier 2 (effective 2010) and Tier 3 (effective 2012) versions of the standard. For example, a 50-inch TV will have do limbo underneath a 153-Watt peak for Tier 2 compliance and 108-Watts for Tier 3. We're confident that some clever engineering will allow LCD to reach those figures; the real impact might be on plasma TVs, however. It pains us to say it, but plasma's going to have a hard time making that grade; of course, that's assuming that plasma TVs are still being made and marketed towards consumers who value the Energy Star label. For those of us who want efficiency and ultimate image quality, it's time to pull for LED-backlit LCDs.

Scientists purportedly improve blue OLED efficiency by 25%
The holy grail of OLED is upon us. With scientists around the world working to improve efficiency of the short-lived blue OLED in order to better align with lifespans of the green and red counterparts, a team from Pacific Northwest National Laboratory has reportedly taken a huge leap in solving the whole thing. These gurus have conjured up new host materials for a blue phosphorescent OLED that's at least 25 percent more efficient than existing blue OLEDs, but regrettably, details beyond that are few and far between. Word on the street has it that PNNL scientists are expected to gather and discuss the findings before heading to a meeting of the American Chemical Society later this spring, and we'll be crossing our fingers that whatever they've found is both a) cheap and b) easily implementable.[Via OLED-Display]
Baby steps: new solar cell efficiency record isn't awe-inspiring
Granted, we've no idea what it takes to really push the efficiency level of a solar cell, but we're getting pretty bored with these incremental improvements year after year. If you'll recall, the record for solar cell efficiency sat at 40.7 percent in 2006, and that was raised to an amazing 40.8 percent last August. Today, researchers at the Fraunhofer Institute for Solar Energy Systems have announced an all new milestone: 41.1 percent efficiency. According to team head Frank Dimroth, the crew is simply "elated by this breakthrough." Meanwhile, the rest of planet Earth is suddenly depressed by the thought of perishing from old age before this data point ever breaks the big five-oh.[Via Gizmag]
Plasmas from Hitachi, Pioneer, LG, Panasonic break onto the Energy Star list
Not to be outdone by their LCD brethren, plasma displays from Hitachi, LG, Panasonic and Pioneer have earned the right to wear Energy Star badges (or sashes). All told, 43 models from the manufacturers successfully navigated the 208-Watt "on mode" and less than 1-Watt "standby mode" limbo stick, and although the Plasma Display Coalition isn't crowing about smashing the requirements like JVC did with its LCDs, it's still a testament to advances to plasma efficiency. For us plasma-philes here at Engadget HD, knowing our obsessive pursuit of image quality isn't destroying the planet is a bit like having our cake and eating it, too.
New wind turbines at least 30% more efficient, Earth one step closer to salvation
Still addicted to oil like the rest of the world? You might reconsider wind power rehab now that a startup called ExRo has developed turbines that it says are consistently 30% -- and in some situations as much as 100% -- more efficient than the standard kind. The traditionally-used mechanical transmissions have been replaced with an inexpensive electric alternative that can adapt to changes in wind speed more efficiently. Also, many small generators are used instead of a large one, so the turbines can be customized in production to suit the intended installation site. If this is the real deal, it beats the 0.1% increase we saw in solar cell efficiency a few months ago, and those Maglev uber-turbines are still on the horizon. Hey Sun -- jealous yet?[Via DailyTech]
New solar cell efficiency record (barely) achieved at 40.8%
Just under two years ago, researchers at Boeing-Spectrolab managed to achieve 40.7% solar cell efficiency. Two years later, scientists at the US Department of Energy's National Renewable Energy Laboratory have demonstrated their nerve by trumpeting an all new world record... one that's 0.1% points better than the last. Yes, your new record now sits at 40.8% -- tremendous progress, wouldn't you say? Looking outside of the numbers, you'll find that these cells differ "significantly" from the prior record holders, which enable them to be thinner, lighter, cheaper and altogether swanker. That's it for now folks -- come back in a couple years, we hear 40.9% is just around the bend.[Via CNET]
Wrath Hunter Talent Analysis, Part I: Marksmanship
Hunter talents are out, and there's definitely a lot to say about them, both good and bad. While we have discussed some of the changes to the lower Survival tree, what we haven't touched on is all the new talents and the talent changes in other trees. If I was to sum it all up in one sentence, I'd say this: The 51 point talents look lackluster, but most of the rest is downright drool inducing. Marksmanship's early tiers are now full of easily obtainable goodies for any Hunter, Survival's gained even more group and raid buff utility, and Beastmastery has even more amazing pet synergy. There's a lot to cover, so we'll tackle it one tree at a time. First, we'll look at Marksmanship, which was once premiere Hunter tree, but has fallen a bit to Beastmastery in Burning Crusade. It's certainly seen some marked improvement for Wrath so far, and even if you don't plan to spec Marksmanship, you'll at least want to know about the first few tier talents, as you'll probably want to grab many of them anyway.
Mage buffs on the horizon
Here's some more good news today for mages. On top of Hypothermia going back from 45s to 30s, Kalgan has stopped by the mage forums to promise some additional buffs in person. These probably won't make it into 2.3, but he says they'll go in "in the near future." My guess is that translates to 2.3.X or 2.4. It looks like Blizz is basically in a "buff" swing recently, which fits in with their general design philosophy -- start underpowered, and then build the classes up as necessary. Buffs make far fewer people angry than nerfs do.What are these buffs, you ask? Trainable Ice Block, and "to-be-finalized improvements to mana issues in longer fights" (source). We've been seeing more and more skills moved to trainable as the game has matured, from Evocate to Holy Fire to Improved Sap. Ice Block mades good sense to add to that list. Kalgan's reasoning is that IB is something they want to be able to design PvE encounters around all mages having, and that it helps open up the range of viable specs for PvP. As far as the "mana issues" improvements, it's hard to comment too much on that without any details, but efficiency is good. Any speculation on what they're going to do there?Oh, and in a later post, Kalgan lets slip that mana gems are also slated to be buffed. Let that be a sort of after-dinner mint of buffage.
Marvell chip claims to make PCs more energy efficient
Mark this down as a little out there, but a new Marvell chip claims to improve the efficiency of desktop and laptop power supplies by determining and then optimizing the amount of energy each particular application needs. Named a "power factor correction controller," the chip enables computers to comply with new Energy Star guidelines that require computers to use at least 80 percent of the energy supplied to power them. It's not the only chip out there that claims to improve efficiency using this method, although Marvell has already started producing the chips with the aim of hitting full volume production in Q1 2008, and seeing them in PCs thereafter.
Can saltwater be burned as fuel?
A gentleman from Erie named John Kanzius made a somewhat "shocking" discovery while he was working on a radio-wave generator he had developed for the treatment of cancer. While attempting to desalinate sea water using radio frequencies, he noticed flashes, and within a few days, had saltwater burning in a test-tube as if it were a candle. The discovery spawned interest from the scientific community, mostly concerned with whether or not the water could be used as a fuel, and of course, healthy doses of disbelief. Last week, a Penn State University chemist named Rustum Roy held a demonstration proving that the science is sound, noting that the water doesn't burn, though the radio frequencies weaken the bonds holding together the salt, releasing hydrogen which is ignited when exposed to the RF field. Mr. Kanzius and Dr. Roy say the question now is the efficiency of the energy, and are presenting the technology to the US Department of Defense and Department of Energy to investigate how useful the technology will be. Of the plentiful maybe-fuel (which apparently burns so hot it can melt test-tubes) Dr. Roy says, "This is the most abundant element in the world. It is everywhere," and (without recognition of the poetic irony, as far as we can tell), "Seeing it burn gives me chills." Check the TV report after the break to see the water in action.[Thanks, Paul]
Korean researchers develop uber-cheap solar cells
We'll go ahead and hand it to Spectrolab for crafting such an immensely efficient solar cell without regard to cost, but a team of Korean researchers have reportedly conjured up a rendition of their own that, you know, would actually be feasible to commercialize in the not too distant future. The team -- led by Lee Kwang-hee of the Gwangju Institute of Science and Technology -- has reportedly created a diminutive plastic solar cell that touts "6.5-percent efficiency," and while that number pales in comparison to other alternatives, it's the pricetag that's of interest here. Apparently, existing solar cells that use silicon semiconductors cost around "$2.30 to generate one watt of electricity," whereas this group's solution costs just ten cents per watt. Better yet, plans are already in motion to increase efficiency up to 15-percent, after which we could see these things hitting the marketplace at large "by 2012."
Spectrolab designs highly efficient solar cell
While we certainly applaud the designers at Spectrolab for developing a solar cell that's reportedly "twice as efficient as typical rooftop solar panels," we're stifling most of our excitement until it actually leaves the laboratory. Nevertheless, the Boeing subsidiary has apparently cranked out a cell that utilizes metamorphic materials and is "designed for photovoltaic systems that use lenses and mirrors to concentrate the sun's rays onto small, high-efficiency solar cells." The unique semiconductors used are said to resemble ones that adorn satellites and planetary landers, and can capture three layers of the solar spectrum versus the single layer that traditional solar panels collect. Unfortunately, it seems that the eventual goals for this thing are rather ho hum, as the crew only expects the cells to hit 45-percent efficiency within the next six or so years. C'mon folks, you've already got alternatives at 40.
Big timers join up to launch Climate Savers Computing Initiative
Although a number of household name computer vendors have already inked their name on some sort of green agenda, now it looks like things are getting a bit more aspiring as Intel and Google have joined the likes of Dell, EDS, EPA, HP, IBM, Lenovo, Microsoft, PG&E, and the World Wildlife Fund (among others) to launch the Climate Savers Computing Initiative. The lofty goal is to"save $5.5 billion in energy costs and reduce greenhouse gas emissions by 54 million tons per year," which translates into an amount equal to removing "more than 11 million cars from the road" by 2010. Supposedly, vendors in agreement with the initiative will abide by the new 90-percent efficiency target for power supplies, which looks to be the main player in garnering such massive reductions. Feeling guilty about pulling the trigger on that 2,000-watt PSU yet?[Via ArsTechnica]
UK's Green Shift could result in dummy terminals galore
While a plethora of companies having already joined forces to create a modern day Captain Planet of sorts, England is making sure it doesn't fall off the green bandwagon just yet by launching a Green Shift taskforce to reduce carbon dioxide emissions. But the most intriguing aspect of the operation is how it could translate into more dummy terminal usage and lower sales of, say, more popular home PC software. Led by the Manchester City Council, the crew will reportedly "host functions such as office applications, email, and internet surfing on data centers rather than on individual computers," and it also aims to use 75-percent fewer resources in the actual production of computers. The initiative is said to be a full out assault on "cyber-warming," as local Government Minister Phil Woolas so eloquently put it, and the service should hit full stride late in 2009 after a brief pilot program gets executed early next year. Unfortunately, mum's the word on how these elusive data centers will connect with users and what types of hardware will be required to run them.[Via PCWorld]
LG shuts doors on A1 plasma manufacturing plant
While some may have balked at Sony taking an early exit from the PDP market, LG is becoming the fourth major player to reevaluate its investment in plasma after Philips was caught claiming that LCD TVs would likely shape its strategy and Hitachi began to look intently overseas for buyers. Reportedly, LG is closing the doors of its oldest plasma manufacturing plant in Gumi, South Korea as it hopes to "increase operational efficiency and reduce costs." The removal of the A1 plant will drop its plasma capacity from 430,000 to 360,000 panels this year, and it should save the company somewhere between "$22 million and $32 million per year." Notably, LG currently sits in second place in quantity of PDPs shipped worldwide, but considering the perpetual nosedive of HDTV prices over the past year or so, we can't say that Life looks too Good in the PDP arena right now.[Via PCMag]
Thermoacoustics behind all-in-one cooker, fridge, and generator
Sure, building up a campfire in order to roast some eats in the wilderness could be fun for awhile, but for the reported "two billion people that use open fires as their primary cooking method," we're sure it loses its luster somewhere along the line. The University of Nottingham is hoping to change all that, however, by attempting to develop an all-in-one gizmo that acts as a "cooker, a fridge, and a generator," and relies on biomass fuels for energy. The £2 million ($3.96 million) SCORE (Stove for Cooking, Refrigeration and Electricity) project seeks to create a "wood-powered generator capable of both cooking and cooling food," and it will purportedly rely on thermoacoustics to cut down on pollutants, increase efficiency, and be more reliable to future consumers in Africa and Asia. No word just yet on when this newfangled kitchen appliance will be ready to ship, but a portable version would probably do quite well in the camping market.[Via CNET]
enano's latest mini PCs tout Core 2 Duo, energy efficiency
Joining Epson and a growing host of others in the miniscule PC arena, enano is throwing its own offerings in the hat while boasting about greenness all the while. The generation e2 lineup sports "book sized" enclosures, a sleek black paint job, and four different models to suit your fancy (and budget). All four units rely on one of Intel's Core 2 Duo processors, but apparently, none are sporting the Santa Rosa love just yet. The machines can be configured with up to 2GB of DDR2 RAM, 160GB of SATA hard drive space, an integrated TV tuner, gigabit Ethernet, 802.11b/g, 7.1 surround sound audio, and feature Intel's GMA950 integrated graphics set, an SD / MS / MMC card reader, a total of four USB 2.0 ports, one 4-pin FireWire connector, DVI or VGA out via adapter, S-Video out, and audio in / out ports to finish things off. The box itself weighs in at just three pounds and measures 8.8- x 6.8- x 1.65-inches around, and while the company claims that you'll save a bundle on energy costs with this power sipper, the up front charges ranging from around $1,200 to near $2,000 probably makes up for it.[Via CNET]
Dubai Burj al-Taqa skyscraper to generate all its own energy
A skyscraper in Dubai is being designed so that it generates all of its energy through renewable means such as wind turbines and solar panels. On top of the tower will be a 200 foot turbine that harnesses the power of the wind, and an array of solar panels on the roof and a series of islands that stretches over 161,459 square feet. The tower will also feature a massive solar shield to protect it from the sun, and vacuum glazed glass that will reduce the amount of heat absorbed from the extreme temperatures (up to 50 degrees C / 122 degrees F), presumably meaning less reliance on traditional air conditioning. Talking of air conditioning, the main system for cooling the air inside the tower uses a convection system which pulls in cold air at the ground level, and sucks it up out of the top of the tower. The air conditioning will use seawater, and underground cooling units lower the temperature inside to 18 degrees C / 64.4 degrees F. This building may be a technological beacon for environmentally friendly skyscrapers, but as a commenter on metaefficient points out, new building designs don't do much to solve the inefficiency of older buildings in cities. Although that doesn't mean we can't imagine what it'd be like to work and live in a sea of glass and metal without feeling slightly bad about it.[Via Metaefficient]
Mileage maniacs hack Toyota's Prius for 116 mpg
In a presumed attempt to prove questionable reports about the Prius' true fuel efficiency dead wrong, a Japanese group of mileage maniacs (or nenpimania) have assembled to push their hybrids to the brink and utilize a sly combination of hackery and zen-ish ways to elicit extreme miles per gallon figures. One such enthusiast burns his gas money on special tires, cardboard surround for the engine bay (saywha?), and blocks of foam rubber that occupy the grill, and somehow manages about 100 mpg by "hacking into the Toyota's computer" and carefully manipulating the accelerator with just his large toe. One upping even him, however, is a fellow mpg freak dubbed Teddy-Girl, who has reportedly become such a master of the "pulse and glide" method of driving that she can crank out 116 miles on a single gallon of fuel. Of course, sustaining such numbers on even mild inclines is entirely unlikely, and we're fairly sure you're hearing best case scenarios with all these gaudy numbers, but until we're all cruising in purely electric whips, this doesn't sound like a half bad approach to keep those trips to the pump at a minimum.[Via The Raw Feed]
Software patch could boost MPG in gas-powered vehicles
No doubt, we've seen more than a few sensational sounding gizmos aiming to provide (nearly) limitless power and create energy out of thin air, but a simple software patch could enable the vast majority of the world that's still stuck in gasoline-powered vehicles to get better gas mileage. John Kessels at the University of Eindhoven has partnered with Ford to develop software to improve engine performance and save "up to 2.6-percent" in terms of miles per gallon. Quite simply, the patch dynamically switches the dynamo, (which charges the car battery) on and off when it is "particularly inefficient for the engine to power it, thus improving the overall efficiency of the engine." Mr. Kessels even stated that "a simple cable and a software upgrade" was all that would be necessary to boost MPG, and thankfully it's not exclusive to Ford motors. Notably, a fuel savings closer to six-percent could likely be achieved if a "powerful starter motor" was installed to allow your engine to cut off entirely and restart quickly in between long traffic jams, but both methods have a good bit of testing to go through before being deemed non-abrasive to batteries and engine components. But hey, there's nothing a firmware upgrade can't fix, right?
