Pavegen taps pedestrians for power in East London (video)

by Joseph L. Flatley posted Oct 29th 2009 at 1:41PM

When we were kids, we assumed that in the future everything would be powered by tiny nuclear fusion reactors: automobiles, toothbrushes, time machines (apparently we read a lot of sci-fi from the 1950s). The truth, as usual, is more mundane than all that: some of the more promising advances we've seen in green energy has been kinetic, taking the movement of automobiles or the tides and converting it into electricity. Pavegen, for example, can be set in public walkways to generate as much as 2.1 watts of electricity per hour from the footsteps of grizzled pedestrians. Using marine grade stainless steel and recycled materials, just five of these bad boys distributed over a well-worn sidewalk should be able to generate enough energy to keep a bus stop going all night. If not put into nearby lighting, the units are equipped with lithium polymer batteries for storage. Currently being tested in East London, look for them throughout the UK in 2010. Video after the break.

US government lays out cash for wall-based, in-home 'smart meters'

by Darren Murph posted Oct 27th 2009 at 4:47PM

Google has its PowerMeter, Microsoft has its Hohm and Obama has his "smart meters." Got it? Good. Around two years after UK taxpayers began footing the bill for in-home energy monitors, it seems as if America's current administration is looking to follow suit. While visiting the now-open solar facility in Arcadia, Florida today, the Pres announced that $3.4 billion in cash that the US doesn't actually have has just been set aside for a number of things, namely an intelligent power grid and a whole bundle of smart power meters. Aside from boring apparatuses like new digital transformers and grid sensors (both of which are designed to modernize the nation's "dilapidated" electric network), 18 million smart meters and 1 million "other in-home devices" will be installed in select abodes. The idea here is to give individuals a better way to monitor their electricity usage, with the eventual goal set at 40 million installed meters over the next few years. Great idea, guys -- or you know, you could just advise people to turn stuff off when they aren't using it, or not use energy they can't afford. Just sayin'.

America's (newest) largest solar plant set to go live in Florida

by Darren Murph posted Oct 25th 2009 at 8:33AM

If all goes well, this 25-megawatt solar plant in Florida won't be America's largest for long, but it's not like we'd pass up the opportunity to let this $150 million facility bask in its own glory (and the sun, if we're being thorough) while it can. The Desoto facility is just one of three solar projects that Florida Power & Light is spearheading, and judging by the proximity of this one (in Arcadia) to the 75-megawatt facility planned for nearby Charlotte County, we'd surmise that the two are linked in some form or fashion. President Obama is expected to show up rocking a set of Kanye glasses underneath a welder's mask when the plant is fired up this Tuesday, and while it'll only provide power to "a fraction" of FP&L's customer base, it'll still generate around twice as much energy as the second-largest photovoltaic facility in the US of A.

Technocel PowerPak pulls double duty as portable battery and home charger

by Darren Murph posted Oct 15th 2009 at 2:37PM

Wouldn't it be nice if your home phone charger could double as a charging device itself when taken on the road? Yes, yes it would. Technocel undoubtedly agrees, as its PowerPak does just that. When plugged into a standard wall outlet, it can simultaneously charge whatever USB device is plugged into it (amongst others, considering the bundle of tips that are included) and juice up its internal cell; once unplugged, the integrated battery can provide enough power to a dead mobile to let you yap for around three hours, or just enough to make it through whatever sobfest your ill-willed SO has planned for you next week. It's expected to go on sale in around a fortnight at various retail locations and Sprint stores.

Mizzou's nuclear battery to power things smaller than your brain can imagine

by Darren Murph posted Oct 10th 2009 at 11:52AM

Oh yeah, everyone loves the extended battery, but are we really kosher with the added bulge? A team of boffins at the University of Missouri certainly aren't, as they've spent the last good while of their lives researching and developing a new nuclear battery that could be used to power devices much smaller than, well, most anything. The radioisotope cell, as it's called, can reportedly "provide power density that is six orders of magnitude higher than chemical batteries," and while some may question the safety of this potentially volatile device, the liquid semiconductor (used instead of a solid semiconductor) should help ease concerns. The current iteration of the device is about the size of a penny, and it's intended to power a variety of MEMS systems. Now, if only these guys could find a way to make a standard AA last longer than a week in our Wiimote, we'd be pleased as punch.

TDK unveils fashionable, colorful solar chargers (video)

by Ross Miller posted Oct 7th 2009 at 9:51AM

Solar power is something we've seen touted in every big tech trade show for as long as we can remember, but it's taken until recently to make it a bit easier on the eyes. Enter TDK's design-, color-, and sun-enhanced chargers, found hanging out under a hard light in the back of the company's CEATEC booth casually powering a fan. It's definitely a step up from dark paneling, so how long until we see this applied to some stylish mobile phones, eh world? Video after the break.

Toshiba's DMFC fuel cell seen 'powering phones' at CEATEC (video)

by Darren Murph posted Oct 6th 2009 at 5:58PM

Toshiba has been promising the world a healthy dose of fuel cell chargers for what feels like ages now, with its most recent swearing happening just two months ago. Here at CEATEC, the company's wares were being trumpeted by KDDI. We witnessed a standard handset have its stock battery removed and replaced with an admittedly bulky fuel cell container. The booth attendant proudly juiced up the cell, clipped it onto the phone's rear and mashed the power button. Within seconds, the device booted up normally, and a handy level indicator on the charger itself kept us in the know on how much life was left. Or -- you know -- maybe the whole thing was just an elaborate hoax to fool English-speaking media into thinking this stuff was really nearing its commercial release. Have a look at a brief video just beyond the break, but try not to get your hopes up too high. No need in having your heart broken again unnecessarily.

Sony dives into wireless power game, makes it way more interesting

by Darren Murph posted Oct 2nd 2009 at 2:17AM

We've been watching wireless power startups spin their wheels for years on end, and while we've netted a few contact-charging solutions along the way, there's still a dire need for bona fide wireless power. A most unlikely candidate has just shown up to deliver that very need, with Sony's wireless power supply system reportedly pushing some 60 watts of juice across 50 centimeters (nearly two feet) of crisp, cool air. Currently, the magnetic resonance setup is running at about 60 percent efficiency, but we're sure the engineers behind the breakthrough aren't satisfied yet. So, should we expect to see a prototype BRAVIA HDTV at CES 2010 that needs no AC cable to function? Please Sony, say yes. Say it emphatically.

Helix Wind launching wind-powered cellphone tower trials in US and Africa

by Laura June posted Oct 1st 2009 at 12:52PM

Helix Wind, a company that produces some very distinctive-looking wind turbines, is getting ready to start new trials in the US and Africa. These trials will involve testing the vertical wind turbines as a source of power for cellphone towers in areas where they may be off the grid, and carry much higher operating costs. The turbines should produce enough energy to power the cellphone towers, and pay for themselves within about six months. The trials are set to start at the end of the month with local Nigerian provider Eltek NSG as a main participant.

Carbon nanotubes find yet another purpose, could star in ultra-reliable batteries

by Darren Murph posted Sep 21st 2009 at 8:29PM

Carbon nanotubes are kind of like peanuts. They both seem pretty simple at first glance, but with a little work, you can make pretty much anything out of 'em. Take this case, for example, as MIT boffins have discovered that by forming the tube-shaped molecules of pure carbon into minuscule springs, they could be "capable of storing as much energy, pound for pound, as lithium-ion batteries." The real kicker is exactly how they'd do it -- "more durably and reliably." Essentially, these newfangled cells could be left alone for years on end without losing their charge, and unlike conventional batteries, these wouldn't suffer from performance degradation when exposed to temperature extremes. Of course, anything as pie-in-the-sky as this is probably at least a decade or so out from Walmart shelves, but considering that the group responsible has already filed a patent, we'd say they're pretty confident in the possibilities.

MotionPower speed bump installed at NJ Burger King, McDonald's and Wendy's feel slighted

by Darren Murph posted Sep 10th 2009 at 12:49AM

We can't say we doubted that New Energy's MotionPower speed bump would actually be installed at a New Jersey Burger King, but it's always refreshing to see a plan morph into reality. As of now, those in Hillside heading to have it their way will cruise over the kinetic energy harvester before retrieving their grub, which has the potential to create around 2,000 watts of electricity from a car hitting it at five miles per hour. As of now, the hump is simply there to test storage potential, but New Energy is hoping that the next generation of the tech could be placed at a variety of fast foot eateries, parking lots, toll booth plazas and anywhere else where folks need a little assistance in maintaining a sensible speed. Check out the read link for a plethora of shots, and feel free to splurge on a #4 combo today if you're in the area -- Ma Earth will thank you.

Power Bridge flips the strip upside-down, instantly kills ugly

by Darren Murph posted Sep 7th 2009 at 5:58AM

Oftentimes it's the most complex of designs that leads into the next level of a technology. Other times, it's the simplest of tweaks that completely revolutionize things. Take the Power Bridge concept, for instance, which simply takes the conventional power strip, turns it upside down and calls it a day. Designed by Hyukjae Chang, the immensely simplistic device keeps those gaudy plugs underneath the top bridge, and it also makes routing the connecting AC cables all sorts of simple. There's no telling when this thing will finally leave the drawing board and enter the production line, but you can rest assured Monster Cable will figure out a way to throw a "power conditioner" in there and charge two or three C-notes for it.

Solar Roads get small DoE contract, confidence to change the world

by Darren Murph posted Sep 6th 2009 at 6:06PM

Solar roadways? Yeah, we've seen 'em before, but we've yet to see America's own Department of Energy give any one development company such a notable vouch of confidence. Just recently, the DoE handed over a $100,000 contract to Solar Roadways, which is just enough to build a prototype of the "first ever Solar Road panel." The 12- x 12-foot panels could theoretically be embedded into roads, and when shined upon, could pipe good, clean electricity straight into the grid. Heck, they could even boast LEDs in order to alert drivers to upcoming accidents or changes in road conditions. Reportedly, each panel would cost around $7,000 (at least initially), and if these were used on the entire US Interstate system, we could pretty much forget about using non-renewable energy sources to power our homes and businesses. Of course, our government is simultaneously wasting money on repaving perfectly good roadways with antiquated asphalt, so there's a tremendously great chance that this won't amount to anything.

Ford's vehicle-to-grid communications system charges plug-in whips on command

by Darren Murph posted Aug 19th 2009 at 2:32PM

If you're dreaming of always plugging your future AC-friendly hybrid in during the wee hours of the morning in order to juice up for the lowest price, you're certainly using your noodle. But what about instances where you can't choose when exactly you'll be plugging in? Fret not, as Bill Ford and Company has you covered. The automaker, in collaboration with a slew of utility partners, has today introduced an intelligent vehicle-to-grid communications system that would theoretically enable vehicle owners to plug their ride in and tell it precisely when to begin and / or end charging via the navigation screen. Users could also define the completion time for charging or the desired rates in order to better control spending, though all that planning could be ruined by some random prankster who decides to yank your cable when you're not looking. And really, who cares about saving a penny or two on charging when you can get two hundred and thirty miles per gallon? Oh, wait...

OSU foresters swap tree fibers for rubber in fuel efficient tires

by Darren Murph posted Jul 26th 2009 at 12:41PM

Leave it to a gaggle of brilliant wood science researchers at Oregon State University to figure out that we've been doing this whole "tire" thing wrong for generations now. While studying some uses of microcrystalline cellulose, which can be made easily from practically any type of plant fiber, these Earth-loving gurus discovered that said material could actually improve the efficiency of vehicle tires when used in place of silica. Granted, only about 12 percent of the silica -- which is used as a reinforcing filler in the manufacture of rubber tires -- was swapped out, but the resulting tires gripped just as well in wet weather while decreasing the rolling resistance during those dry summer months. Furthermore, tires constructed with these fibers could be made with less energy, though long-term durability studies are still needed to prove that this whole plan is viable for more than a few thousand miles.
