By - December 30, 2013 3 Pictures
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

By - September 30, 2013 11 Pictures
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.

By - March 25, 2013 12 Pictures
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

Magnic Light claims new form of no-contact bicycle dynamo lighting

By - February 16, 2012 3 Pictures
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

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.

Also on show was Eton’s new Rukus portable Bluetooth sound system, which comes in battery- and solar-powered versions. Read More
