I for one charge my phone every day and am still amazed how short its power lasts. Quite often I run out of juice in the middle of the day, for these moments I came up with the Ifan (conceptual prototype) An hardware App in the shape of a soft rubber skin with the energy wind fan included. Just slide it around your Iphone and it will charge everytime the wind blows.
Your Smartphone relies on high tech battery power and power management which you charge almost every day in your outlet in just half an hour. By using a modified computer fan it took us 6 hours to charge the phone, rather long we think… but it works. We can shave off many charging hours by redesigning the fan blades, making it more efficient in catching the wind while sun bathing at the beach, doing walking trips in the mountains or just holding it outside your car window while driving along… we’ll keep you posted.
