Currently, green energy/battery rechargers appear to be among the most intriguing eco-friendly gadgets out there, but they often have drawbacks. People who own a car can recharge their devices via lighter adapter easily while driving to work, but those who ride motorbikes or bicycles to work may have some difficulties. Although there are many green portable energy/battery rechargers on the market, they require cyclists or bikers to carry more equipment, reducing their convenience.
Wind-Helmet integrates the recharger into the safety helmet, allowing the cyclist and biker to carry fewer portable devices, at the same time providing a means for recharging their portable digital products (such as mobile phone, digital camera, MP3 player) while on the move.
The headgear would have a small propeller that could catch the flow of wind on top of the helmet, which acts as a turbine connected to a generator to in turn recharge a set of batteries. With this stored electricity, you can charge any kind of electronic apparel, such as your cell phone, iPod, GPS or whatever digital device you have onboard.
There's no doubt that some thought went into this design, but we're not so sure it'd be a good idea in practice. A small generator connected to one of the bike's wheels would certainly be more efficient; alternatively, a small array of solar panels could gather as much energy without putting a drag on the bike's engine.
However, the Wind Helmet is only a concept for the time being, and there is no information available on whether this device has any chances of becoming reality anytime soon. Until then, you'll just have to use the already available rechargers and if you want to be a friend of the environment, then you shouldn't worry, as there are already several types of solar chargers available on the market.
