The more we depend on portable power – to run everything from our phones to our laptops to our iPods, iPhones and iPads – the more smart designers and entrepreneurs are working on ideas to make recharging on the go a little easier.
Although just a concept at the moment, the idea for the twirling battery (pictured above) is that you can simply spin your phone’s battery around your finger for a few minutes and create enough charge to make a quick call or text.
The designers, Song Teaho and Hyejin Leethe, are guesstimating that around 130 twirls will give you enough juice for about two minutes of talk time. (My highly scientific test with a keyring suggests that this would take about 30 secs, but may confuse fellow passengers on public transport).
How could you make our increasingly mobile lifestyles a bit simpler?
