The Magnic Light iC tail light, in place on a bike

German inventor Dirk Strothmann certainly caught some peoples' attention last year, when he released his Magnic Light touchless dynamo bike light. Instead of slowing the bicycle down by pressing on its tire, engaging magnets in its wheels, or adding friction in its hub, it's able to generate electricity simply by being close to a spinning metallic rim. Now he's about to launch the Magnic Light iC, which will offer some interesting new features.  Read More

There are already a number of gadgets available that are powered through good old-fashioned mechanical energy, but those usually involve cranks that can be uncomfortable to use and bulky to carry around. Mipwr Dynamo represents a different approach: it's an iPhone case with a hidden lever that can be pressed down repeatedly to charge the battery, but is still slim enough to fit in your pocket.  Read More

Tern claims that the S18 offers a rigid ride, even for larger riders

Folding bicycles can be a convenient option for those with limited storage space or whose trips partially involve another form of transport. Of course, a folding bike frame usually comes with some performance compromises but Taiwanese folding bike manufacturer Tern has a new bike that it believes can "redefine the folding bicycle category" with no compromise to performance. The Eclipse S18 also offers a number of integrated technologies, including a self-powered lighting system and seat post pump.  Read More

The onboard battery of the Sun and Cloud camera from Superheadz can be charged via USB, a ...

Though the increasingly competent cameras in smartphones are making the digital compact all-but obsolete, there is still a healthy market for novelties like the Digi Cam and Digital Harinezumi 2++. Another decidedly lo-fi cutie from the same product stable is the Sun and Cloud "self-generating" pocket camera. Its battery can be juiced up via USB, but the palm-sized snapper offers users greener charging options in the shape of a PV panel on top and a hand crank on the side.  Read More

The Etón Corporation has now announced details of pricing for the BoostTurbine and BoostBloc portable power packs that debuted at IFA 2012 back in September.  Read More

Eton Corporation launched the BoostTurbine and BoostBloc USB battery packs from the Power ...

Eton came to IFA 2012 to show off its Rukus portable Bluetooth sound system and FRX Series of preparedness radios to Europe's green technology lovers but also treated us to a surprise unveiling of its new Power Boost USB battery packs. As the name suggests, the BoostTurbine sports a hand crank to keep the conversation going even when its own juice is drained. Meanwhile, the largest capacity BoostBloc portable power pack is claimed to be capable of simultaneously charging two smartphones.  Read More

The Magnic Light is a contactless dynamo bike light, that reportedly utilizes eddy current...

Despite the continuous advances being made in lithium-ion battery technology, many cyclists still prefer to use dynamo-powered lights on their bikes – there’s no having to remember to recharge the batteries, no subsequent forgetting to put the light back on the bike, and no worrying about the batteries unexpectedly giving out mid-ride. Dynamos, however, have their own drawbacks. Friction-powered sidewall units slow the bike down and wear out the tire, while dynamo hubs must be built into the wheel, and add to the bike’s revolving weight. Now, however, German inventor Dirk Strothmann has created what he claims is a better alternative – a small, no-contact, self-contained dynamo bike light.  Read More

The Rukus Solar portable Bluetooth sound system's lithium ion battery can be charged by th...

While insufficient battery-life can be annoying in most mobile devices, getting cut off from the outside world because your radio has run out of juice can be much more serious. This is why Eton has been producing various devices powered by hand-turbines and solar panels for some time now. Today’s CES Unveiled saw Eton demonstrating its latest FRX line of self-powered radios that come in three flavors – the FRX 3 and FRX 2, which both sport a solar panel and hand turbine, and the FRX 1, which features just the hand-turbine. Also on show was Eton’s new Rukus portable Bluetooth sound system, which comes in battery- and solar-powered versions.  Read More

BioLogic ReeCharge Power Pack makes the most out of pedal power

If your bike has a hub dynamo, the BioLogic ReeCharge Power Pack lets you run portable USB powered devices while you ride. Whilst we've recently seen bicycle recharge kits, the ability to charge via USB is pretty novel. Basically it's a battery with a USB port that charges from the energy generated by your dynamo and then tops-up your device when you plug it in. That means you can charge the battery and then charge your device when you arrive at your destination, or, if it's practical, charge your device on the go, allowing you to use your smartphone's GPS function whilst riding.  Read More
