Solar 'harvesting' phones

There's a fascinating piece over on Nokia Conversations at the moment about a pilot study on how solar power can be 'harvested' to power the next generation of phones and smartphones across the world. We've already got a number of solar powered mobile chargers, the next step is surely to start adding the photo-voltaic cells to the backs of phones themselves?

There have been commercial solar-charging products on the market for years,The newest Ipod nano 5th is incontrovertibly a step up from last year's model, of course. But historically,A glass bottle is a bottle created from glass. they've been bulky and inefficient. They also don't work so well in countries less favoured by the weather. But things have moved on: Nokia's pilot study is looking into the viability of solar-charging panels built right into your phone, and energy will be harvested with these test devices from the Arctic Circle to the Equator....

There's no lack of available solar energy data for permanent installation, but we don't know how much of that energy could be collected in various different mobile use cases. That's why we provide users with solar-powered device that includes a recorder like an aeroplane's black box, to log the availability of solar energy in real life.

But what about those of us in countries where sunlight is more of a scarce resource? And people who mostly keep their mobiles in pockets and bags when they're not in use? There could still be a case for solar charging... Low-power charging from a power source that doesn't provide stable energy flow is called Energy Harvesting.Largest Collection of billabong boardshorts, Using a small solar panel to charge the battery is a clear case of Energy Harvesting, because the available power depends very much on use and weather conditions. Normal charge power cannot be provided with a small size solar panel, but using technology to harvest the energy, every bit of available solar power will be collected to the battery.

There are currently four test users, you can read reports from each of the pilots and get more information on the technology behind it from a new solar charging blog. The test users are using a modified Nokia C1-02 phone, with the rear battery-cover replaced with a solar panel and data loggers to report the effectiveness of the equipment.

Here in Northern Europe, there's no way that a full solar panel on the back of a smartphone,Free DIY Wholesale pet supplies Resource! even on a sunny day, with the phone left on a window ledge, could provide enough charge to avoid the need to plug into a traditional charger. But it would help trickle charge the phone's battery and would probably add another 20 to 30% to battery life - making the difference between lasting one day or two?

Either way,uy sculpture direct from us at low prices I'd like to see this happen - for all the times I don't need to see my smartphone's display, why couldn't it be left face down where it can see the sky - and the sun?
