Flybus consortium puts the brakes on energy waste, throws it back to the asphalt
For anyone who's logged time city bus surfing, you know there's a heckuva lot of power in those screechy stops and starts. So, it stands to reason there'd be a way to harness that kinetic energy and shuffle it right back to the auto, itself. Well, that's exactly what the Flybus consortium aims to do with a prototype that uses a Ricardo Kinergy flywheel to store energy created from braking, and redistribute it via a continuously variable transmission. The hybrid setup is purportedly much cheaper to produce than current, pricier EV rigs, and would also go a long way towards reducing fuel costs for commercial vehicles. Gearheads eager for a peek at the group's design can get a look-see when it's shown off this month at the Low Carbon Vehicle event in the UK. For everyone else, there are the source links below.
Inhabitat's Week in Green: pencil-tip generators, the Nissan Leaf, and the world's largest wind turbine
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. This week we saw renewable energy take the world by storm as Spain announced plans to construct the world's largest wind turbine and a team of engineers made waves with plans for an underwater turbine modeled after whale flippers. We also saw Boeing shine light on plans to produce a new breed of ultra-efficient solar panels that are suited for space, while researchers in Japan developed a potent new kinetic generator that's as tiny as a pencil tip. Innovative eco transportation also picked up the pace as China rolled out plans to produce the first fuel cell powered light rail train and the world's largest solar-powered boat made its successful maiden voyage across the Atlantic. We also applauded the Nissan Leaf as it took first place as the European Car of the Year and we were wowed by Mercedes' next-generation concept car, which may one day be grown in a lab. We also showcased several new ways that technology stands to wire our lives -- starting with an electronic smart wallet that curbs spending by clamping shut like a clam. We also looked at Harvard's plans for a laptop computer powered by biogas and we were impressed by Nike's next-gen design tools for producing environmentally efficient clothes. Finally, we wrapped up the week with two exciting advances in tablet tech - India is testing a solar-powered I-Slate tablet geared at children in need and Substrata rolled out a gorgeous wooden iPad case that goes light on the earth.
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]
Nokia wants patent on self-regenerating phone batteries, piezoelectrics and much magic involved
In Nokia's own words, what we're looking at is a "piezoelectric kinetic energy harvester." Working along the same principles as kinetic wristwatches have done for a long time already, Nokia's idea is to capture the energy generated by the phone's movements and to refashion it into beautiful, clean-as-a-whistle electric power. By allowing the heavier internal components to move on rails within the phone as part of a "force-transferring assembly," the Espoo think tank has figured out a way to capitalize on all the small forces of acceleration and rotation that we subject our phones to on a daily basis. It would seem overly ambitious to expect this to replace the trusty old charger, but we give credit to Nokia for even thinking about it. Check out some schematics of how this would work after the break. [Thanks to everyone who sent this in]
Conceptual Corky mouse gets charged through motion, doubles as a wine stopper
It's still in concept form at the moment, but America's own Adele Peters just might have a winner with Corky. This obviously cork-based mouse relies on "piezoelectric elements to generate energy every time you click or move it around on your desk," meaning that nary a battery would ever be used to power it. In case that's not sustainable enough for you, the whole thing is made from easily recyclable materials, so it shouldn't mar Ma Earth when it gets tossed at the end of its useful life. Too bad that design has been trumped forty times over by more ergonomic options, but hey, there's always v2.0.
Dancepants: the music stops when exhaustion sets in
We've seen some pretty tortuous fitness wares in our day, but few are as cringe-worthy as this. The conceptual Dancepants Kinetic Music Player is a rather vanilla looking pair of exercise pants, but the internal energy makers generate juice only when the wearer is in motion. In other words, kinetic energy is used to power the connected MP3 player, and so long as you keep hustling, the tunes will keep flowing. Not like you'll really notice that Mambo #5 has stopped right in the middle of the bridge when you're laying on the ground nursing a wicked cramp, but hey...
Pavegen taps pedestrians for power in East London (video)
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. [Via Inhabitat]

M2E Power turns movement into electricity
Looking for power in hard to reach places? Perhaps M2E Power can lend a hand. The company -- recently infused with a pile of money from venture capitalists -- is in the business of creating power through the kinetic motion of everyday human and / or mechanical movement. The idea is that by simply walking or driving, energy can be produced that will power devices on-hand, obviating the use of outside sources -- an idea that will be of particular use to soldiers on duty, as the technology could reduce their load by up to 30-pounds. The devices also contribute to efforts towards clean power and extended mobility on the consumer side, efforts your DS-playing kids will go bonkers for. For those down with the Faraday Principle (energy produced via motion of a magnet through a wire coil), you'll be happy to know that someone is putting the concept to good use -- for the rest of us, well, we'll just be happy if we can get a few more minutes out of our mobile phones.
