Can you hear green? Well, you can now, with Trevor ‘wind-up’ Baylis’ Eco Media Player. It’s about £170. The only bills after that are in the form of calories – one minute of charge via the wind-up handle gives 40 mins of audio play.

“My original windup radio … was 16 years ago … many electronic devices … were inconceivable when I created my radio. Now we … combine the best … modern ideas with … freedom and energy efficiency …”
Trevor Baylis OBE

16 years since the wind-up radio! I know! And what a wonderful piece of low-impact technology. Did we get one 16 years ago? And if not, how much battery usage would we have saved since? Scary…

Included: up to 8GB of memory, mini USB connector with which it can be charged via your PC or Mac, slot for a mini-SD memory card and sockets for headphones and line-in. Plus FM radio, a music player in all the usual formats, video, a voice recorder, a self-styled ebook reader and a startlingly bright torch. (It even has a tourch…).
