Sprint aims to boost network reliability with green sources
Sprint is looking to beef up its own network in hopes that failures like the one that just recently happened in Minnesota will be a thing of the past, and moreover, it's hoping to conserve energy all the while. Reportedly, the carrier is "actively testing and deploying sustainable and renewable energy sources at wireless sites across the country," which could act as both primary and backup energy sources. Hydrogen fuel cells, photovoltaic power and wind power are among the alternatives that Sprint is currently working with, and while no hard dates were listed for when these improvements would be implemented, it did suggest that some $7 billion were going to be spent to "further enhance its networks and meet the demand for more extensive mobile broadband coverage across the nation."
Excess wind energy to be stored underground for future use
We've seen some fairly impressive uses of wind power, but a group in Iowa is looking to actually capture and preserve excess wind energy for use when demand peaks. At the Iowa Stored Energy Park, a number of local utilities is "building a system that will steer surplus electricity generated by a nearby wind farm to a big air compressor," which will be held deep below the ground for future use. The project is being backed by the Energy Department, but more than a hundred municipal utilities in surrounding states are shelling out $200 million to construct the 268-megawatt system. As it stands, Iowa's compressed air energy storage (CAES) installation will be the first of its kind when it's completed in 2011, but there's already work being done in Texas to build a similar unit.[Via Ecotality]
Nissan takes wraps off conceptual Pivo 2 electric car
Apparently, one Pivo just isn't enough, as Nissan today unveiled the Pivo 2 concept car at the Tokyo Motor Show. The fully electric vehicle boasts a 360-degree turning cabin, 90-degree turning wheels and "employs by-wire technologies for braking and steering." Yes, that means that this thing can "drive sideways as well as forward," and thanks to the in-cabin Robotic Agent, you can now rest assured that someone, er, something will be along for every ride to give you tips on finding the nearest parking garage. As expected, there's no telling if this thing will ever show up en masse on dealer lots, but feel free to hit the via link for a smattering of photographs.[Via Autoblog]
Inventor claims electric van can cruise for 500-miles on full charge
We've heard some pretty zany claims when it comes to alternatively-powered vehicles, but Daren Luedtke is suggesting this his homemade electric van can propel itself some "500 miles" (despite other reports stating 150 miles) on a single charge. He also noted that it can be fully recharged in just eight hours, and he has apparently filed for a number of patents on the technology. The prototype Caravan, which took a few hundred thousand dollars to convert, is filled with batteries and also sports a computer that "monitors inputs such as amperage and voltage (his words, not ours)." Luedtke Enterprises is purportedly looking for manufacturers to help bring the technology to the public, and if you're interested in hearing more, you can hit the read link for a video interview with the head honcho himself.[Via CNET]
Toyota looking to develop recharging points for plug-in hybrids?
There's been no shortage of news surrounding Toyota and its hybrid plans of late, so it makes perfect sense to hear that the automaker may be on the verge of inking a deal to "develop recharging points for plug-in hybrid electric cars." Reportedly, Toyota and Electricite de France are set to "announce a deal next week to develop electricity infrastructure for the plug-in cars Toyota plans to launch in a few years." Notably, the agreement is only expected to cover France initially, but neighboring countries could be pursued shortly thereafter.[Via AutoblogGreen]
First all-electric police car takes to the streets
C'mon, fess up -- you'd be a lot less intimidated by a whisper quiet, all-electric squad car than one with a roaring V8, but it's hard to argue the fuel savings that would accrue if an entire precinct resorted to using the former. Such a car has now been loosed by the Connellsville Police Department, which had its combustion engine removed and replaced by a "pure-electric" alternative. The modified Chevy Impala will reportedly cruise for eight hours on a two-hour charge from a 240-volt outlet, but can't chase down baddies in heavy rain for fear of water "destroying its electrical circuits." Furthermore, Coherent Systems International (the car's converter) will be monitoring its effectiveness over the next two years as it aims to "work with other state agencies" and create more alternatively-fueled automobiles for public service.[Via Wired]Read - Connellsville plugs in police car Read - All-electric squad car makes quiet debut
Fujitsu installs hydrogen fuel cell on Sunnyvale campus
Always down for a little self-glorification, Fujitsu has just announced that it has become the "first Silicon Valley company to install hydrogen fuel cell power." The firm reportedly "dedicated a hydrogen fuel cell on its Sunnyvale campus," which aims to provide "clean, efficient power for the campus data center and other operations" and substantially curb carbon dioxide emissions. The UTC Power PureCell Model 200 system will provide half of the energy necessary to cool the campus data center and labs, and Fujitsu claims that it will have a payback "of about 3.5 years and a lifespan of closer to 15 years."
Ford Fusion Hydrogen 999 breaks 200 miles-per-hour
Looks like minuscule RC cars aren't the only alternatively powered vehicles trying to break 200 miles-per-hour, as Ford just became the "world's first automaker to set a land speed record for a production-based fuel cell powered car." The whip used to set the bar, of course, is none other than the Fusion Hydrogen 999, and it reportedly reached over 207 miles-per-hour at the Bonneville Salt Flats in Wendover, Utah without using a drop of gas. Apparently, Ford is hoping that this showcase of speed will somehow translate into advancements that will help us common folk get to work and back sans gasoline, and while we've no idea when a fuel cell propelled Cobra will roll off the line, it did note that a number of fuel cell propelled Focus vehicles were still burning down the roads as part of an ongoing study.[Via AutoblogGreen]
Miles XS 500: the $30000 all-electric sedan?
While a number of fancier all-electric automobiles have still not yet hit the streets en masse, quite a few companies are already looking at the prospects of bringing plug-in cars to a wider range of individuals. One of those folks would be Miles Rubin, who apparently hopes that his "$30,000 Miles XS 500" can deliver the gas-shunning attributes we crave sans the outrageous price tag. Reportedly, the sedan would sport a "top speed of 80 miles-per-hour and a range of 120-miles at 60 miles-per-hour," and the costs would seemingly be kept down thanks to low Chinese manufacturing costs. Of course, Rubin has yet to utter a date in which he expects these Chinese-constructed motorcars to pass our inspections (and earn our trust), and while a low-cost electric whip sounds enticing in theory, we're going to need a bit more evidence that this thing can survive some form of collision before we remove our skepticism caps.[Via AutoblogGreen, thanks Nick]
GM mulling battery rentals for the Chevy Volt
Tossing out the idea of renting / leasing the battery of an electric car isn't exactly revolutionary, but it sounds like GM may be hitching a ride on the ever-growing bandwagon. Reportedly, the firm is mulling the idea of allowing Chevy Volt buyers to "rent the vehicle's battery as a way of pricing the automobile at a comparable level to a traditional, petrol-driven family [motorcar]." Apparently, GM is hoping to get ten years of life from the battery packs and to price the Volt like a "traditional mid-market car." Notably, no further information regarding potential contracts or sales strategies were divulged, but considering the launch date for this sucka is just around the corner, we're sure relevant decisions will be made soon enough.[Via AutoblogGreen]
Think hoping to deliver web-enabled electric car
Wee electric cars such as the one pictured to the right aren't exactly uncommon, but if Think CEO Jan-Olaf Willums can get his dreams to pan out, his version of the urban green car may actually gain some serious traction. Reportedly, the firm has garnered upwards of $78 million from Silicon Valley and European investors who see promise in the carbon-neutral whip, and moreover, in changing the way we all buy and interact with our cars. Ideally, Think will only sell its vehicles online, which would reduce overhead dramatically, and will equip the cars with WiFi in order to become "a rolling computer that can communicate wirelessly with its driver, other Think owners, and the power grid." Notably, Think plans to "to sell the car but lease the battery as a way to overcome one of the biggest conundrums of electric automobiles," and while nothing is set in stone, the "City" could arrive in select locales as early as 2009.[Via Slashdot]
Researchers develop "paint-on" solar cells
The quest to builder a better, cheaper solar cell continues on, as researchers at the New Jersey Institute of Technology have developed a new type of solar cell that can be printed or painted onto flexible plastic sheets. Unlike traditional silicon cells, the print-on cells are composed of carbon nanotubes and buckyballs, which results in substantially cheaper manufacturing costs and greater efficiency, since apparently carbon nanotubes are terrific conductors. The scientists seem pretty pumped about the potential for their tech, with lead researcher Somenath Mitra quite confidently proclaiming that we'll all soon be printing "sheets of these solar cells with inexpensive home-based inkjet printers." Yeah, we're sure there won't be any shenanigans going on in that ink cartridge market.[Via Inhabitat]
Tampa Bay school gets pair of plug-in hybrid buses
From a kid's perspective, we're sure they'd much rather be cruising on the iPod-equipped bus than a vanilla version that gets significantly better mileage, but regardless, a Tampa Bay school will become the first to receive a pair of hybrid buses to shuttle students around while saving between 70 and 100-percent in fuel costs. The vehicles can be fully charged in around six hours, and while the aforementioned improvements are only so drastic for the first "50 miles or so," it's certainly not a bad start. 'Course, school district officials are hoping that fuel savings will eventually lead to more money for classroom improvements, but we reckon it'll be quite some time before the savings on fuel overtakes the up front cost of these (presumably pricey) machines.

Greenbox converts carbon emissions into biofuel
A breakthrough technology developed by three engineering lads in Wales could hold the key to converting carbon emissions into beneficial substances such as biodiesel, methane gas, and fertilizer. The cleverly-dubbed Greenbox was designed to be fixed underneath one's vehicle where it could gobble up carbon dioxide and nitrous oxide until the next fill up, at which point the box would be switched out for a new one while the filled canister headed to a bioreactor for processing. Sounds complicated, we know, but strapping these bad boys beneath every gasoline-powered vehicle in a given nation could boost its biofuel production exponentially -- all without spending another penny (or pence) on research. Unsurprisingly, the trio of inventors are staying mum until they (hopefully) convince the government or a private company to grab ahold, but unless these boxes learn to swap themselves, we can't imagine too many individuals bustin' out the creeper for underbody work at each fuel stop.[Thanks, Jamie]
NC State researchers working up longevous capacitors
If being able to recharge your future collection of batteries "a thousand times more" than your existing stockpile sounds enticing, a team of NC State physicists now have your attention. Thanks to their research on the electromechanical properties of the commonly used polymer polyvinylidene fluoride (PVDF), they have discovered that when combined with CTFE (that's yet another polymer), it may allow capacitors to store "up to seven times more energy than those currently in use." According to Vivek Ranjan, the process moves atoms within the material "in order to make the polymer rearrange with the least voltage," and this storage booster could even be used to allow electric cars of the future to sport the "same acceleration capability as a gas-powered sports car." Sounds like more than a few manufacturers are desperate for something like this, eh?[Image courtesy of Biopact]
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.
NSSO ponders harvesting solar energy via satellites
When you've already got colleagues dreaming up space sunshades, all of a sudden harvesting energy from outside of the Earth's atmosphere doesn't sound like such a stretch. Apparently, ambitious individuals at the Pentagon's National Security Space Office (NSSO) may "begin a study in the near future on the possibility of using satellites to collect solar energy for use on Earth." Notably, the plan actually seeks to not only provide an alternate source of fuel to the oil-dependent dwellers here on Mother Earth, but it would hopefully provide ample energy "to US troops in bases or on the battlefield." As impossible as it may sound, the present probably isn't a bad time to consider such an endeavor now that solar cells are becoming increasingly efficient, and since an actual deployment wouldn't even be in the cards until "around 20 years" from now, it's not like there's oodles of time to waste.[Via Wired]
Fat-burning members power Hong Kong fitness club
So we've heard of dance clubs powered by fresh moves, but now California Fitness, a Hong Kong-based health club wants to jump on the sustainable people-power wagon too. As a group effort between inventor Lucien Gambarota, Wharton grad and entrepreneur Doug Woodring, and California Fitness, "Powered by YOU" will offer exercisers the chance to use their own energy to power lighting fixtures, with excess energy to be stored in batteries. The 13 step, cycling, and cross-training machines will be soon be rigged to encourage members to reduce CO2 emissions as well as their waistlines. According to California Fitness president Steve Clinefelter, someone running an hour each day on a machine can generate 18.2 kilowatts of electricity and prevent 4,380 liters of CO2 from being released each year. It's hard enough battling the bulge on your own, so we're glad to see that these explorations in alternative energy can provide some extra motivation for living a healthy lifestyle. We, on the other hand, will continue to remain seated for the rest of our lives. [Via Inhabitat]
