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.

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.

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.

Power generating backpack is a gift from the gadget gods, Uncle Sam

by Thomas Ricker posted Oct 6th 2009 at 5:49AM

Without a doubt, the military is home to some of the best gadgets. Fortunately for us, the non-lethal stuff often makes it into the hands of consumers after companies finish milking the government of its R&D budget. Case in point: this electricity-generating backup. Designed for the military, the kinetic energy pack is suspended on a rail that generates electricity as you walk. The power generated will charge a standard US Marine-issue lithium ion battery pack or can be directly routed to whatever device you want to charge. The obvious benefit would be limitless power in the field freeing troops from carrying extra batteries on long missions. A power meter on the shoulder strap lets you monitor performance while a three-stage resistance device lets you regulate the power output. A braking mechanism lets you lock down the pack when you want to keep the pack steady. Otherwise, it looks like it'll generate about 8 watts of power while walking or 44 watts of power when running. Do want. See it in action after the break.

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.

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.

Nagano Japan shows off yet another contactless charging system

by Joseph L. Flatley posted Aug 20th 2009 at 10:34AM

It's been little over a month since Showa Aircraft demonstrated a contactless charging system that boasts 90% efficiency over a distance of 60 centimeters -- and now what is this? Nagano Japan Radio Co Ltd. is touting a similar system that works up to one meter, with a pretty incredible 95% efficiency at a distance of 40 centimeters. According to Tech-On, the company is currently hard at work trying to ramp the output up from "several tens" of watts to several kilowatts. As opposed to Showa's recent outing (which relies on electromagnetic induction), this system uses magnetic resonance to achieve its effect. However, as this method "drastically lowers" its efficiency when the position of the sending and receiving units are displaced, the team designed a system that automatically detects coil displacement and reorients itself accordingly. The company hopes to someday charge electronic vehicles with the thing, although we'd be happy if it merely enabled us to stow our WildCharge pads out of sight. They seriously clash with the decor here at Engadget HQ.

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...

WildCharge brings 'wireless' charging to hundreds of devices

by Joseph L. Flatley posted Aug 14th 2009 at 4:33PM

We know you're jealous of your friends' ability to charge up their RAZRs and iPhones sans wires, so how would you feel if we told you that WildCharge's newest solution -- the PowerDisc -- would allow you to use its WildCharger with literally hundreds of devices? It's true! All you need to charge your previously incompatible hardware wirelessly is this one little wire that attaches the PowerDisc to the PowerLink adapter for your Nokia, Palm, LG, Samsung, Sony Ericsson, Micro USB, or Mini USB device. Available on its own for $19.99 or bundled with the WildCharge pad for $64.99. And it looks like the PowerDisc also includes a lanyard -- we know how much you love lanyards! So, have you ordered one yet or what?

Glass leaves sweat to generate electricity, get nervous in public situations

by Laura June posted Aug 3rd 2009 at 4:13AM

Researchers at the University of California, Berkeley, the University of Michigan and MIT have created glass "leaves" with networks of veiny channels filled with water. The smallest channels extend all the way to the edges of the leaf, where open ends allow water to evaporate, which draws water along the central stem of the leaf -- at a rate of about 1.5 centimeters per second. The glass leaves have been wired for electricity by adding metal plates to the walls of the central stems and connecting them to a circuit. Researchers then charge the plates and the water inside the stems creates two conducting layers separated by an insulating layer, which acts as a capacitor. The waterflow is then periodically interrupted with air bubbles, and every time a bubble passes through the plates a small electrical current is generated -- about 2 - 5 microvolts per bubble. The team thinks that on a large scale, artificial trees could be use to generate large amounts of energy entirely through evaporation.

Baryonyx to build largest offshore wind farms in the US, power massive data centers

by Darren Murph posted Jul 23rd 2009 at 8:27AM

Uh oh Mr. Pickens -- looks like you've got some competition down in Texas. With the aforesaid energy baron scraping plans to plant 687 massive wind turbines in Texas' panhandle, Baryonyx has stepped in to do the honors via a slightly different project. Just this past week, Baryonyx won a bid to create a pair of sizable offshore wind farms that Jerry Patterson -- Commissioner of the Texas General Land Office -- says "could be the biggest offshore wind farms in the nation." Additionally, another lease was granted for a prospective wind energy development in the panhandle, and now the company is eager to get going on the green energy gigs. The best part of this whole plan involves that actual purpose of the turbines; aside from providing juice for grids, they'll also be used to energize forthcoming Tier 4 server farms, with a minimum of 750 megawatts of power being pumped to two coastal areas all the while. Ma Earth would be proud.
