It's always frustrating when the battery on your blower goes. Taking inspiration from the long-held nickname for the telephone, the Aeolus would let you breathe new life into your mobile phone's battery -- by blowing on it.
It's not a real phone, unfortunately, existing only in concept form to show off some ideas for environmentally friendly designs. The mock-up includes a fan and solar panel to charge the battery, and calls for the phone to be made of renewable materials, with a low-power single-colour LCD screen. Graphic designer Cyrene Quiamco named the concept after the Greek god of wind.
If you're so green you don't even have a car, attaching the phone to the front of your bike could give the battery a hefty boost. Ideally, bubbles would come out when you blow on it.
This could be of interest to users in developing countries. Nokia recently announced the C1, a cheap dual-SIM phone with a torch built in, designed especially for poorer nations.
