75-megawatt solar plant to power "first solar city" in Florida
Given that Florida has accurately been coined The Sunshine State, it's not at all shocking to hear that America's first "solar city" will be built in the state's southwest corner. Or, at least that's the plan. According to a new report, West Palm Beach-based Kitson & Partners is currently developing a new city near Charlotte County, which will get juiced by a massive 75-megawatt solar plant. Said plant will cost around $300 million to build and will be installed by Florida Power & Light; if all goes well, homes will begin construction on a sizable plot of land dubbed Babcock Ranch by 2011. If things don't go so well, we're told that the actual power plant will still be erected and fed into the larger grid. In other words, Florida's gettin' some solar power, with or without this newfangled concrete jungle.[Via Fark]
U.S. electrical grid penetrated by spies, hackers, or something unfathomably more terrible (update: China responds)
The Wall Street Journal has reported that the electricity grid in the United States has been infiltrated by "cyperspies," in an attempt to map the infrastructure, leaving behind software that could pose potential threats in times of crisis. Quoting anonymous "current and former" national security officials, the report claims that the spies, hailing from China, Russia, and "other countries" have not attempted to do any damage, but that they could, and that these types of intrusions are on the rise. Officials are of course worried about the potential implications of such penetrations, noting that much of our infrastructure, including nuclear power plants and financial institutions, are at risk. Unfortunately for the WSJ and its Cold War-era headline, the article goes on to state that it's not really possible to know whether a particular attack is "government sponsored," or just the work of regular old hackers from those regions running amok in cyberspace. Additionally, spokespeople from the Russian and Chinese Embassies vehemently deny their respective governments involvement in any such work. The Wall Street Journal, of course, fails to point out the most obvious of explanations: it's aliens. Update: China has officially responded to the report. From a WSJ blog post: "The intrusion doesn't exist at all," Chinese Foreign Ministry spokeswoman Jiang Yu said at a regular press conference. "We hope that the concerned media will prudently deal with some groundless remarks, especially those concerning accusations against China." "I have also noticed that the U.S. White House had denied the media reports," she said.
Piezoelectric nanowires could lead to blood-powered iPods, cellphones
You know what'll be awesome? Actual end products resulting from this presumably nonstop research on piezoelectric nanowires. Yet again we're hearing of a new group of researchers that have figured out a way to harness electricity from life's simplest things: walking, a heart beating or even the flowing of blood. Put simply, the gurus have discovered how to use zinc oxide nanowires in order to generate an electric current when "subjected to mechanical stress." The difference here, however, is that these critters could actually be implanted under the skin, though the scientists have made quite clear that there isn't a timetable for commercial production. In other words: yawn.[Via textually, image courtesy of NSF]
NYT: Google's PowerMeter to let users track electricity usage
The New York Times is reporting Google will announce a free web service tomorrow called PowerMeter that'll let users track energy consumption in their homes or business, provided there's a means to upload the data. That part of the equation's gonna be up to other companies to create compatible devices, and while no manufacturing partners have been named, we'd suspect strange bedfellow GE will probably jump aboard pretty quickly. The service is expected to roll out in the next few months. Ready to give the boys in Mountain View even more access to your life?Update: The official site has launched. According to the FAQ, PowerMeter is currently in closed beta. There's also a video about the program, which you can peep after the break.
Garbage-powered garbage truck now making its way across merry England
The Brits get all the cool stuff -- Queen Elizabeth II, The Sex Pistols... and now a rubbish truck that runs on rubbish (sort of). That's right: up in Huddersfield they've just unleashed a modded three-and-a-half ton Smith Edison Ford Transit garbage truck that tools around, picking up garbage, hauls it to a nearby Energy from Waste power station and recycling center which then burns the 'bage to make electricity for the next day's route. The garbage also produces about 10 megawatts of excess electricity per day which is dumped into the grid for added fun. The truck's got a top speed of about 50 miles per hour, and is apparently so quiet that the locals fear it could be dangerous to unsuspecting pedestrians. Maybe they could slap a speaker on there and pump some Oasis as a warning? Just a thought.
World's smallest working fuel cell has high potential, low voltage
University of Illinois researchers have developed what they claim is the world's smallest working fuel cell, and it's certainly a good bit tinier than anything we've seen. The itty-bitty battery measures 3 mm x 3 mm x 1 mm and is comprised of just four layers: a water reservoir, a thin membrane, a chamber of metal hydride, and an assembly of electrodes. It can produce 0.7 volts and a 0.1 milliamp current for about 30 hours, with a newer model boasting similar voltage and 1 milliamp of current. That's not gonna juice your BlackBerry anytime soon, but scientists suggest it could be used for simple electronics and microbots. As for future application, we're hoping one day can power a fingernail-sized smartphone.[Via Register Hardware]
Student charts electrical usage in real-time, much to Big Brother's delight
It's our best guess that University of Florida PhD student Jason Winters woke up at 10:00AM ET this morning and took an approximately 18-minute shower. How did we come to this conclusion? Using an AC clamp attached to an ioBridge, the biomedical engineering scholar measures the main electrical lines entering his house and sends the data to a Google charts widget on his personal blog that reports the kilowatt-hour usage in real time. As a footnote, he presents an example graph of when the hot water is turned on, which then produces close to 4500 watts. That's just over the amount of power he used this morning for about 1100 seconds. Of course, we can't say for certain any of these morning events really transpired, but then again, we don't exactly want to know. Hit up the read links for directions on DIYing this.
Waste heat close to becoming useful in cooling / lighting applications
Not that waste heat in general hasn't been repurposed for non-wasteful activities before, but researchers at Doshisha University are now edging ever closer to making useful the previously annoying thermoacoustic phenomenon. For those not really tied into the science realm, said phenomenon is a nonlinear one in which "heated air autonomously transforms into sound when passing through small mesh holes in a wire sheet." Gurus are now developing a cooling technology that would have heat converted to sound, where it would then be transferred through a tube and reconverted into heat; furthermore, other whiz-kids are looking to generate actual electricity from the racket. In related news, the thermoelectric conversion is being used to transform waste heat from candles into energy for LEDs, which would emit more light than the candle powering it. Pop on past the break for a demonstration of the former.
Prototype piezoelectric road could generate power by simply sitting there
By sitting there and getting ran over by motorcars, that is. In an effort to best other power-generating highway options that involve solar panels and enlarged blender arms, Britain's Environmental Transport Association is looking to test a prototype highway that's embedded with piezoelectric crystals. Essentially, the process would work much like the power-generating Tokyo station floors we saw earlier this week; each car that squishes a crystal would contribute a tiny bit of energy, and the collective effect could be enormous. In fact, it's estimated that a single kilometer of roadway could generate 400-kilowatts of energy, or enough to power around eight small cars. And we're no rocket scientists (nor physicists), but we're assuming these whiz kids already made sure these magic crystals weren't friction-generating, too. Right?
Piezoelectrics could lead to voice-powered cellphones
Just imagine -- yapping for hours on end to your dream lover could actually leave your cellphone with more juice than what it started with. This completely bizarre scenario could theoretically become a reality according to new research from a professor at Texas A&M University, and it's all thanks to the magic of nanoscale piezoelectrics. If you'll recall, we've seen this technology generate energy in wearable devices before, so it makes sense that sound wave energy could also be captured and converted into electricity. Of course, we're still a good ways away from this being ready for commercialization, but who knows how quickly this could come together if placed in the capable (albeit unpredictable) hands of Dr. Walter Bishop.[Via phonescoop, image courtesy of Rutgers]
Spanish entrepreneurs aim to kill standby power drain, get gold star from Mother Earth
The amount of power consumed from appliances and such left in standby mode is certainly up for debate, but what's not is the fact that they'd all be better off, um, off. That's according to Spanish inventors who have developed a technology to automatically detect when gadgets fall into standby mode and then shut 'em off completely; the best (read: differentiating) part, however, is that devices won't have to go through their boot-up sequence again after rising from the grave. Of course, this technology is worthless with devices such as security systems and DVRs, which obviously require at least some power at all times in order to effectively answer the call of duty. Still, the elaborately named Good for You, Good for the Planet is hoping to get its tech into power strips and individual gizmos soon, with one hotel chain in Spain already testing a prototype. Here's hoping these thoughtful entrepreneurs aren't squeezed to death by all of the collective hugging from trees that's surely going down.[Via WalletPop, image courtesy of GavinBell]
Plasma Plant turns your old junk into electricity, which can then be used to create more junk
The transmutation of garbage into energy is a particularly modern form of alchemy. We've seen it done on a smaller scale in the past, but now a company called Geoplasma is assembling the country's first plasma refuse plant in St. Lucie County, Florida. Scheduled to go online by 2011, the plant will process 1,500 tons of garbage a day, adding 60 megawatts to the power grid -- enough energy to power 50,000 homes. The plant works by vaporizing refuse with a 10,000 degrees Fahrenheit stream of plasma. The organic components (food, fluids, paper) create a pressurized gas that is then used to turn a turbine, while any inorganic refuse (metals) that may be present condenses, later to be collected for industrial uses. But will it power a Flux Capacitor?[Via Inhabitat]
Sanyo builds prototype pedometer that powers itself while you walk
These portable power generating options are a dime a dozen now, but we thought you'd still want to know that Sanyo has invented a device that'll let you turn your health obsession into electricity to power your health obsession -- a vicious cycle if we've ever seen one. It's a pedometer that generates just enough energy (40 microwatts) to keep itself ticking when the swinging motion of its health-nut wearer's body causes tiny parts to move around. Sanyo hopes to use the technology for other low-power devices in the future. As for us, we'd rather remain utterly otiose and let our battery slaves do the work for us, though we can imagine something like this might, with some improvements, prove useful to those villagers who have to walk 12 miles to charge their cell phones.

Vizio goes Energy Star 3.0 compliant, launches 32-inch EcoHD LCD TV
Following in the eco-friendly footsteps of Insignia, Vizio has announced that 100% of its HDTVs that are shipping now to US / Canadian retailers "meet or exceed Energy Star 3.0 requirements." The flat-panel maker claims that at least nine of its models actually exceed the specifications by as much as 25%, and every last one of its 22- / 19-inch sets use far less energy than a conventional 60-watt light bulb. In related news, the company is also taking this opportunity to officially launch its 32-inch EcoHD LCD HDTV, which slurps down 44% less energy than a typical 32-inch LCD TV. The set will pack a 12,500:1 dynamic contrast ratio, SRS TruSurround XT audio, multiple HDMI inputs and a stylish white piano colored bezel. If that sounds like something you'd be interested in, you can latch on later this month for $499.99.
All Insignia LCD TVs to meet or exceed Energy Star 3.0 spec
While Best Buy completely failed to issue a press release trumpeting the inability of its latest Profile 2.0 Blu-ray deck to pass Energy Star specifications, it didn't hesitate to pump one out extolling the power-sipping virtues of its Insignia LCD televisions. In case you weren't aware, the Energy Star 3.0 specification went into effect at the beginning of this month, and any Insignia LCD TV manufactured after November 1, 2008 will meet those requirements; in fact, six of the models will exceed the requirements by 15% of more. Um, cookie?
Updated Energy Star spec goes into effect November 1
The new Energy Star 3.0 TV specification -- this time including a test for how much electricity televisions use while turned on, not just while off -- goes into effect next month. According to CNET's tests, the difference in power saved by more efficient (but not necessarily ideal PQ) default settings could be as much as a $100 a year, although that will vary based on the TV and the settings. Of course the new rules mean only 25 to 30-percent of TVs are expected to be able to meet the standard, but when you see it on a box, it will actually mean something. Punch the read link for the final draft, we're just going to turn some unnecessary lights off.[Via Crave]
New solar generator system from Solyndra is totally tubular
We all know the internet is not a big truck, and the rolling blackouts in California not that long ago showed our power grid isn't either. Part of the solution could be a series of tubes, a new type of solar generator from a company called Solyndra that replaces the usual square solar roof panels with something that would make Senator Stevens proud. The company's photovoltaic rods are able to catch rays from any direction, meaning they don't need to be tilted to point at the sun. Also, since they're not shaped like a silicon kite, they don't need the same big, beefy installation brackets. This cuts installation costs in half and has helped to drive $1.2 billion in orders from eager would-be customers of this three-year-old startup. Want to see 'em for yourself? Head on down to the Solar Power International Expo next week in sunny San Diego.[Via Make]
AlertMe warns of energy vampires, kills them remotely
In-home power consumption monitors are trendy pieces of kit lately, with a new one popping up every few months. But, while they're all happy to just kick back and tell you what a wasteful pig you're being, a new service from UK security company AlertMe could actually make you more efficient. Subscribers to the company's monitoring plans, which start at about $260 plus another $17.50/month, will be able to purchase Smart Plugs for $43 each that can communicate wirelessly to an AlertMe Heating Controller. From there subscribers can monitor their energy usage online via computer or phone. That's all standard stuff, but the service also includes keyfobs that will automatically turn down the heat and deactivate devices when you leave, and allows users to manually control the plugs and the thermostat by text message, meaning you'd never be more than a few thumb-presses (and a 20 cent service charge) away from a warm and inviting home.

Einstein's eco-friendly refrigerator concept dusted off, put to good use
Given how large the green bandwagon has become, it's no real shock to see an energy-saving concept from the 1930s being exhumed and investigated further. Scientists at Oxford University have begun to take a closer look at an early invention from the great Albert Einstein in order to hopefully create refrigerators (and appliances in general) that could be used completely without electricity. Back in the day, Sir Albert created a mechanism that had no moving parts and used only pressurized gases to keep things chilly. Once compressors became more efficient in the 50s, however, the idea was tossed aside. Now, the idea obviously has greater appeal, and if things keep humming along nicely, a completed prototype should be erected by the year's end.[Via Physorg]
EnergyHub minds your electricity, saves you cash
We've seen electricity-monitoring / controlling devices similar to the EnergyHub before, but few have provided such a handsome interface or modular, expandable options. The device uses a touchscreen control panel (familiarly referred to as a "dashboard") to help gauge and adjust energy levels for satellite outlets that it communicates with. The data will be accessible and adjustable online, and users will also be able to compare their stats with other eco-tweakers or neighbors. The company claims the devices could reduce energy costs by 20 percent for homes that employ the system. There's no word on a release date or pricing, but we'll keep you abreast of any exciting developments.[Via Inhabitat]
