Terra-Gen lands major funding, expects to complete America's largest wind farm next year
And you thought that 1,000 megawatt wind farm planned for Lake Erie was going to be huge. Terra-Gen Power recently secured a staggering $1.2 billion in construction financing, which it fully intends to use on 3D projectors, PlayStation 3 consoles and parts necessary to build America's largest wind farm. Granted, only one of those points is actually true, but we suspect you're hanging with us. The latest round of cash will help build four wind power projects with a total of 570 megawatts of capacity at the company's Alta Wind Energy Center in Kern County, California. But when you put that with projects already in motion, you're left with a 3,000MW wind power initiative, which should be completed and operational "in the first and second quarters of 2011." So, anyone feeling up to topping this?
HP data center fueled by hopes, dreams and... cow dung
We've seen data centers use excess heat for greener purposes, but how's about injecting a little green into the other side of that equation? HP Labs is on that very wavelength, going so far as to publish details on how these centers could be partially powered by none other than cow manure. Yeah, cowpies. The essential thought process went a little something like this: "Data centers need a lot of energy. Dairy farms create a lot of methane. Let's make it happen." Purportedly, 10,000 dairy cows could "fulfill the power requirements of a 1-megawatt data center -- the equivalent of a medium-sized data center -- with power left over to support other needs on the farm," and heat generated by the data center could "be used to increase the efficiency of the anaerobic digestion of animal waste." The stomach-twisting details can be found beyond the break, but we can't be held responsible for any images you conjure up. Remember -- once your third eye sees it, you can't un-see it. [Thanks, Bob]
nPower's PEG Personal Energy Generator up for pre-order, starts kinetically recharging gadgets in June
Charging battery-powered things while traveling has always been a challenge, and while there's no shortage of portable solar chargers on the market, none have exactly tickled our particular fancies. Maybe the PEG from nPower will enable us to get some juice on the go, a kinetic-based "personal energy generator" that pledges to recharge gadgets by harnessing your movement. Sadly, the company lists no actual specs for the device beyond USB 2.0 compatibility, leaving us guessing when it comes to the all-important question of "How far do I need to run with this thing to recharge my celly?" We'll find out in June when the $149 wunder-baton ships. Order now and you can get yourself a limited edition model with "First Mover" engraved on there. Better than "Late Bloomer," we suppose. [Thanks, Daniel]
Tesla pulls in $465 million government loan to build Model S electric sedan
The Detroit News is reporting that Tesla has closed on a $465 million low-cost loans from the Energy Department to work on its next electric vehicle, the Model S sedan.The funds will apparently be used by the company to build manufacturing plants in California. The loan, which closed on Monday and was approved back in June, will come from the Advanced Technology Vehicle Manufacturing Program, which has about $25 billion to dole out to automakers manufacturing energy efficient vehicles. The Model S will, when complete, boast an up to 300-mile driving range, and will hit up to 60 mph in 5.5 seconds. It's supposed to hit production in 2012 with an output of 20,000 units (that means cars) per year.
New York gets its first solar EV charging station, you can't use it
What do you do when you've got two disused shipping crates, some photovoltaics, and a couple buckets of toxic green paint? Why, you make a solar electric vehicle charging station, the first in New York as it happens. It was created by Beautiful Earth Group, which whipped up this self-contained charging station to juice the company's car, a similarly painted BMW Mini E that just so happens to fit nicely inside -- so long as you don't want to open the doors too wide. About three hours charges the little sucker up for its maximum range of 100 miles, which ought to be just enough to get you out to the Hamptons. Not that you'd want to go there this time of year. Update: We searched for an earlier solar station and came up empty, but vyper0 commented to let us know that this is indeed not the first for NY state, just the first for NYC. There was one installed out on Long Island earlier this year, which would mean you could not only get out to the Hamptons, but get back!
Mini Hydro Turbine concept could bring renewable energy production to your bathroom
Environmentalists would have you believe that leaving the faucet running while you brush your teeth puts an unnecessary drain on the environment. We always disagreed, and if Jin Woo Han's concept Mini Hydro Turbine ever goes into production we might finally have something to back up our argument. The device would capture the "free" energy of your tap to spin a little generator, in theory producing enough juice to charge up an electric toothbrush or shaver. That actually sounds somewhat reasonable, but Han's suggestion of powering your boiler with this thing is probably a bit optimistic. It would also take quite an optimist to think this could some day appear in a bathroom made of tiles and not pixels, but we'll keep on hoping; pairing this with a turbine toilet might enable us to take our homes completely off the grid -- or our bathrooms at least.[Via Gadget Lab]
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]
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]
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]
Mitsubishi's i MiEV electric car to be tested in California
Mitsubishi's i MiEV electric car has spent some serious time on the streets of Japan, but before long, the fuel-shunning vehicle will be roughin' it here in the US of A. The auto maker is teaming up with Southern California Edison and PG&E in order to see how it fares in LA traffic and how to best integrate it with the power grid. As of now, the whips should be cruising down the carpool lanes in Q4, though a few modifications may be needed in order to comply with US laws. Plans are to test the i MiEV for three solid years, and hopefully the $30,000 ride will be made available for purchase shortly thereafter (or earlier, if we're fortunate). What now, MINI?[Via Wired]
Texas wind power initiative to blow other states away
Oh sure, Rock Port, Missouri managed to snag the title of being "100% wind powered," but Texas' new plan will make the Show Me state's gusty initiatives look awfully weak. Officials at the Public Utility Commission recently okayed a plan to "build billions of dollars worth of new transmission lines to bring pollution-free energy from West Texas to urban areas." The ginormous Lone Star state is already the nation's leader in wind power, but when said plan is fully implemented (pending final approval), it'll produce more wind energy than the next closest 14 states combined. Granted, customers will be paying a touch more ($4 per month is the current estimate) for all this clean energy, but pundits assert that the cost is minor when looking at just how much this will help out Mother Earth. Look for everything to go live in four to five years, barring any unforeseen setbacks.[Thanks, Adam]
Dyson actually not looking to build electric car, just a wicked fast vacuum
Look folks, just because Dyson can build a motor with enough oomph to power a vehicle, that doesn't mean it's actually going to. At least that's the message a company spokesperson wants you to believe. Contrary to earlier reports, James Dyson is not looking to enter the electric automobile sector in any way, shape or fashion. Said spokesperson was quoted as saying that "James Dyson did say that [Dyson's] new digital motor could power a car, but it is not working on, and [we] have no plans to create an electric car." Okay, but can you at least make the Ball 2.0 street legal?[Via AutoblogGreen, image courtesy of Telegraph]
Dyson looking to motor into the electric car arena?
Dyson (yes, that Dyson) could be looking to play a role in the next great electric automobile. Just let your brain simmer on that a moment, and see if you can stifle any forthcoming laughter. Believe it or not, the British inventor famous for his iconic vacuum designs is actually developing a "powerful lightweight motor that could enable electric cars to zoom along for hundreds of miles without causing pollution." In theory, the eventual vehicle would scoot about much quicker than the majority of sluggish electric vehicles and solar panels would be tacked on the roof for regeneration in sunlight. Of course, some analysts are suggesting that he continue to keep his innovative motors in household gizmos, and rather than strike out on his own to invent a new car, he could simply partner with an existing automaker and toss in his design genius to craft something that's not horrifically ugly. Sounds pretty good to us.[Via Core77, image courtesy of Telegraph]
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.
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]
Crystals hold promise of affordable solar energy, may have been purchased on eBay
We have no real way of verifying whether or not these so-calls crystals were purchased alongside some bizarre time machine on eBay, but we'll take this guy's word for it and assume not for the time being. Reportedly, University of Queensland professor Max Lu has teamed up with researchers in order to grow "the world's first titanium oxide single crystals with large amounts of reactive surfaces." Put simply, these very crystals can "absorb sunlight and convert it into electricity." It's said that Lu has been working on the project for some 15 years, and even now, he doesn't expect the creation to be commercially viable for another decade. Aside from morphing into fairies and making dreams come true, the things could also be used to "purify air and water." Pair this up with an invisibility cloak and we'll really be in business.[Thanks, Brendan]
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.

Lily-shaped pads could generate solar energy in Glasgow
We've seen some pretty far-fetched efforts meant to capture the sun's rays and convert 'em into energy, but this one holds a special place in our hearts. Rather than consuming acres upon acres of desert land or simply placing a plethora of panels atop some roof, ZM Architecture has an idea that would land a slew of large lily-shaped solar panels in the River Clyde. After winning the International Design Awards Land and Sea Competition, the concept has been passed on to the Glasgow city council in hopes of a trial going forward in the near future. Essentially, energy gathered by the discs would be transformed and exported to the national grid, and integrated motors could rotate the pads in order to "follow the sun for maximum output." Just gotta watch for those sunbathers sure to swim over and kick back on a panel of their own.[Via Inhabitat]Read - BBC reportRead - IDA winner report
E-Fuel's Micro Fueler creates Ethanol from sugar in your backyard
Far from being the first at-home biofuel kit we've seen, E-Fuel is hoping to target consumers with a hankering for fueling up their vehicle with homegrown goodness. The Micro Fueler claims to be the first backyard Ethanol brewer made specifically for use at one's abode, and according to the outfit's CEO, the premise behind it is quite simple. By mixing water, sugar and yeast, individuals can receive E100 Ethanol in a matter of hours. More specifically, it's noted that a gallon of fuel can be derived from ten gallons of sugar, and while that may not sound like the most efficient conversion rate in the world, the company is quick to point out that costs can be lowered via federal, state and local credits along with carbon trading coupons. Those eager to start fueling up before they even leave the house can order one now for $9,995, though we're told not to expect shipments until Q4.
