How much does it cost to just leave your HDTV plugged in?
While it's true that we waste plenty of electricity each year just so our electronics are ready to go when we are, we think it's worth it. TV Snob pointed us towards an article in Good Magazine which indicated that a Plasma TV was the worst offender -- and by a large margin -- but the math doesn't jive with ours. According to the article, leaving a plasma plugged in all year will cost you about $150, which seems crazy. So we grabbed a Kill-o-watt and hooked it up to a 60-inch Pioneer Kuro while it was off, and measured a 20 watt draw. Now we didn't major in math or anything, but according to our calculations that is only about $20 a year, (20 watts * 8760 hours / 1000 * $.11) not $150. In fact even if we actually used the TV for eight hours a day, at about 500 watts, it'd still only cost us $170 (including the standby draw). Either way, we're glad they got us thinking about how much power we're using, but at $20 a month to watch HD, as far as we're concerned, it is money/power well spent .
Another team figures out how to convert waste heat into energy
Not that mad scientists haven't figured out a way to convert waste heat into energy, but a team from Ohio State University has developed a new material that does the same sort of thing... just way, way better. The new material goes by the name thallium-doped lead telluride, and at least in theory, it could actually convert exhaust heat from vehicles into electricity. According to a new report about to hit the journal Science, the material packs "twice the efficiency of anything currently on the market," though it still seems as if it's a good ways out from being ready for commercial applications.

Sharp solar panels to be used in two Japanese mega plants
Sharp has certainly been an integral part of these solar installations before, but the latest endeavor by the city of Sakai and the Kansai Electric Power Company isn't anything to sneeze at. The initiative will see a pair of "mega solar plants" constructed, one of which will crank out around 10,000 kW while the other outputs 18,000 kW. Once the plants go online in 2011, expectations are that CO2 emissions will decrease on the order of 10,000 tons per year. Of course, a staggering ¥5.0 billion ($46.5 million) will be coughed up in order to make it happen, but you can bet Mother Earth will certainly see it as money well spent.[Via CrunchGear]
Offshore wind power park to energize Delaware homes
Unlike Rock Port, Missouri, the entire state of Delaware won't be 100-percent wind-powered after Bluewater Wind constructs a $1.6 billion wind park just off its shore, but the state will be able to "light about 50,000 homes a year" for the duration of the 25-year contract. Said agreement was just nailed down between the aforesaid firm and Delmarva Power, and it hopes to start powering homes via wind by 2012. The offshore site will sit around 12 miles off Rehoboth Beach, with a number of turbines to be planted 90-feet into the sea floor and sport three blades apiece measuring 150-feet long. It's noted that vacationers and locals alike won't be able to notice the park from the beach except on a few remarkably clear days, but if their energy bills sink because of it, we don't really think they'll mind, anyway.
MIT solar dish holds promise for low-cost energy production
Look out 1366 Technologies, you've got yet another solar-based MIT spin-off company vying for business in the alternative energy sector. The company's name is RawSolar, and in due time it could end up selling solar dish arrangements that could power factories or even heat / cool office buildings. Recently, a team of students and faculty celebrated as a prototype dish proved that it could concentrate sunlight by a factor of 1,000, which obviously bodes well for converting that into useful energy here on Earth. Another standout feature of the dish is its small size, and furthermore, the material required to build it is relatively inexpensive and accessible worldwide. Sounds like all the ingredients for a successful startup are there, now we've just got to wait and see if anything becomes of it. We're watching you, RawSolar -- don't let us down.[Thanks, Spencer]
Beacon Power hopes to juggle electricity more efficiently
Bay State startup Beacon Power isn't just another wind / solar / hydroelectric outfit. Oh no, this firm is more concerned with reducing the emissions from the energy plants we already have in place. Put simply, the company's 2,800-pound flywheels are used to store and output energy when needed, a service Beacon's CEO is dubbing "frequency regulation." Essentially, said devices will "match power supply to the grid with power demand from the grid," which curbs energy waste and keeps loads in perfect balance. As it stands, the only disclosed expansion plans include more of Massachusetts and New Hampshire, but if it can rope in enough customers, we reckon the sky's the limit. Video after the jump.[Thanks, John]
Green Plug starts small, signs on Westinghouse
Remember Green Plug? That universal connector we detailed last month which aims to replace wall warts and help Mother Earth out in the process? Turns out, said outfit has just landed its first real believer as Westinghouse committed to using the smart power technology. Even Darwin Chang, Westy's CTO, admitted that his firm "wasn't the largest, but somebody has to be the first." Chang is hoping that utilizing said tech will help it cut costs by eliminating the need to ship power adapters with its wares, but we'd say that's being pretty optimistic. Really, the only way that will go over well is if hordes of other firms jump on the (currently desolate) bandwagon in short order -- any takers?[Via PCWorld]
ElectraTherm's Green Machine converts waste heat into electricity
Converting residual industrial heat into something usable (read: electricity) has proven to be more than a novel concept on more than one occasion, and ElectraTherm's giving the process one more vote of confidence by installing its Green Machine at Southern Methodist University. Just this past week, the firm flipped on its first commercial waste heat generator at the Dallas-based institution, with hopes to generate "fuel-free, emissions-free electricity at three to four cents per kW/hr during payback period and under a penny/kW hour thereafter." The 50kW rig has so far exceeded expectations, and the firm is now forecasting that its units will have a "subsidy-free payback period of three years or less." Of course, we aren't told exactly how many zeros reside on the left of the decimal or anything, but folks in the area can get a tour of the installation later this month.[Image courtesy of Jetson Green]
Tesla coils seen wowing onlookers, cooking hot dogs
Believe it or not, tesla coils are good for more than just creating lighting, protecting one's laptop or cranking out a sweet tune -- and the folks watching a dazzling demonstration at Maker Faire 2008 can attest to that. Apparently a group of prototype (1 / 12 scale, no less) coils were seen sparking up the evening in San Mateo, California, but it wasn't the visual energy or unmistakable hum that caused all that saliva to form in the mouths of onlookers. Oh no, it was the fact that a dozen hot dogs were simultaneously roasted and made ready for safe consumption. Check out a video of the action right after the break.
Piezing dress generates power, attracts nerds as wearer moves
Solar-powered dresses are so two years ago. These days, dames in the know are all about that piezoelectric material, evidenced by the incredibly flashy Piezing. Dreamed up and designed by Amanda Parkes, this piece of garb is all set to steal the show at the 2ndSkin expo in San Francisco, and according to CNET, it features electricity-generating fabrics around the joints of the elbows and hips. When the wearer walks, bends or gets downright nasty on the dance floor, the mechanical stress conjures up energy which is stored as voltage in a built-in battery where it can presumably be used later for charging your favorite handheld gizmo. Sure gets our electrons flowing.[Via textually, image courtesy of James Patten]Read - 2ndSkin expoRead - CNET article on Piezing
UCLA researchers create self-healing, power-generating artificial muscle
We've seen self-healing materials and artificial arms, but a team of researchers hailing from UCLA have taken two fabulous ideas and wed them together to create "an artificial muscle that heals itself and generates electricity." Put simply, the contracting / expanding of the material can generate a small electric current, which can be "captured and used to power another expansion or stored in a battery." The scientists have relied on carbon nanotubes as electrodes rather than metal-based films that typically fail after extended usage, and in an ideal world, the research could eventually lead to (more) walking robots and highly advanced prosthetics. Integrate an AC adapter in there and we're sold.[Via CNET]
Device converts controller rumble to electric shocks
"How much better would games such as Mortal Kombat or Streetfighter [sic] be if you were ELECTROCUTED each time you were hit!" No, that's not a rhetorical question (though our answer would be "not at all better") ... it's the web site introduction to the Mindwire V5, a new British product that replaces those annoyingly rough rumbling controller sensation with a series of gentle, soothing electric shocks. Ahhh, bliss.Using a special controller converter (pictured) and a series of five adhesive pads, the V5 sends force-feedback activated shocks that the web site compares to those of a muscle toning machine. While the device will work with practically any game, the site recommends using it to enhance fighters and first-person shooters (just be sure to stay away from Rez)Though the site advertises plenty of safety features, the litany of warnings makes us worry about how safe this device actually is. It's probably moot for us, though --- at £99 (about $196), this one is only for well-off masochists.Also see: Military sim "shoots" back[Via Pocket Lint, Thanks Foolio]
This Pikachu video is shocking
Ah, science. We're not exactly sure how this experiment works, at least this blogger isn't (being a history major and all), but we still love it. Why? Because Pikachu gets to shoot out electrical bolts in real life. We always knew the little critter had it in him, but what other Pokemon characters' powers would you like to see recreated scientifically? Also, if any of you Bill Nye types want to explain the workings of Tesla coils, go right ahead.[Via GoNintendo]
Ghana man killed by exploding handset?
Truth be told, we aren't exactly inclined to believe this here article is entirely accurate, but nevertheless, Modern Ghana is reporting that a resident was recently killed by an exploding cellphone. Notably, this unfortunate accident wasn't due to a faulty battery, or at least that hasn't been blamed just yet. Rather, the young man simply answered his ringing mobile while it was still plugged into the wall, and seconds later, electricity flowed into the cellphone unrestricted and threw the man back. Reportedly, he was pronounced dead on arrival at a local hospital, and we're sincerely hoping that investigators get to the root cause of all this if indeed the tale is true.[Via textually]
Researchers dream up rain-powered devices
There have certainly been gizmos to surface throughout the years that react in some form or fashion to rain, but Jean-Jacques Chaillout and colleagues at the Atomic Energy Commission in France are fantasizing about using those diminutive droplets of water to actually power useful creations. After using computer models to find out just how much energy could be created by rainfall landing on piezoelectric materials, they determined that between 1 nanojoule and 25 microjoules of energy could be generated per drop. Granted, that won't keep a WoW gamer crankin' through the eve, but it could be used in everyday sensors that just need a smidgen of power in order to beam back results or data to ground control (or Major Tom). So yeah, these may not work so well in Death Valley, but we hear Amazonia could really benefit.[Via NewScientist, image courtesy of ABC]
Researchers hope to charge up gadgetry with body heat
We've heard of firms tinkering with the idea of converting excess heat directly to energy, and apparently, a team of scientists from the US Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have done just that. Oddly enough, the researchers admit that they're still unclear on how their findings actually work, but they've nevertheless discovered how to increase the conversion efficiency of converting waste heat to energy "by a factor of 100." The authors of the report suggest that clothing constructed of material embedded with thermoelectric modules could one day "recharge mobile electronic devices off the heat of one's body," and while we're certainly stoked about the idea, we're already conjuring up awful images in our minds about what this garb will actually look like.[Via textually, image courtesy of FourEyesJokeShop]
Hackers reportedly targeting cities' power systems
We know, hackers tend to get a pretty bad rap these days, but with some of 'em out there creating ginormous gridlocks in Los Angeles and shutting down networks in enemy territories, we sort of understand the sentiment. Most recently, it seems that hackers are being blamed for "penetrating power systems (sound familiar?) in several regions outside the US, and in at least one case, causing a power outage affecting multiple cities." That's according to Tom Donahue, a CIA official, who failed to dole out critical details such as where or when the attacks occurred nor how many folks were actually left in the dark. 'Course, Bruce Schneier, CTO of security firm BT Counterpane, warns that these attacks could in fact be aided by individuals with administrative access to said systems, implying that "human vulnerability" could share at least some of the blame. Don't worry guys, we're faxing CTU right now, they'll be right on it within 72 business hours.[Image courtesy of WPS]
Super Soaker inventor looking to double solar efficiency
Did you know the inventor of the Super Soaker, Lonnie Johnson, is a nuclear engineer with more than 100 patents in his green-lined pockets? Really, you didn't? Well, now that you're all caught up with Basic Gadgetology 101, we'll fill you in what he's been up to lately. Johnson has developed a new solar technology called the Johnson Thermoelectric Energy Conversion System (JTEC for the acronym-inclined), which is "like a conventional heat engine." A closed box system takes heat as an input, creates pressure from heat differential, which generates electricity by forcing ions through a micron-thick ceramic membrane. The big news: this system purports to be as efficient as 60%, versus the 30% efficiency achieved through normal photovoltaic panels. While Johnson's invention may prove itself to be a game changer in the quest for cheap and renewable electricity, we don't think it'll be nearly as fun as using pressurized air to blast water at your pals. Now, maybe if he made a solar-powered water cannon ...
Free electricity meter to educate UK residents
By this May, the UK government wants to provide free clip-on electricity meter devices designed to show residents exactly how much they're spending on electricity, with the goal of encouraging them to reduce their consumption when they're made aware of the cost of the electricity they use. Of course, the government doesn't want to foot the bill for the project themselves, they'd like to see the energy companies pick up the tab. The energy companies, however, say the program is a stopgap on the way to more sophisticated "smart meters." Call us old-fashioned, but we prefer to break out the calculator and figure out the energy usage of our electronics manually, just like our great-great-grandfathers did.
Water-activated portable power generator on the horizon
We've seen our fair share of diminutive power generators, but rather than worrying with vibrations or hyperventilating, Millennium Cell and Horizon Fuel Cell have teamed up to deliver an iteration that's water-activated. The pair has been working together on this technology for some time now, and apparently, it's readying a beta that will be demonstrated at next year's CES. The portable power generator incorporates a "unique water-activated cartridge system," which is designed to quietly provide clean energy to consumer products in emergencies and when far, far away from an electrical outlet. Reportedly, the device will provide an AC socket alongside two USB connectors, an operating time of over 16-hours, infinite shelf-storage life and 400-watts of instant juice by just adding H2O. Regrettably, we still have no idea what this thing actually looks like, but considering that CES is less than two months away, we'll soon be seeing what this $400 gizmo can do up close and in person.
