Cyclus – A Personal Electricity Generator

Satoshi Yanagisawa is a sustainable designer based in Farnham in the south-east of England.  He’s developed “Cyclus“, a concept for a wind-up USB charger that will give around 30 minutes juice for a couple of twists.  Based on a spring and DC motor, this is simple technology in a great design and is a far more elegant solution than other solutions such solar (photovoltaic) chargers or external batteries.  In particular, the Cyclus can be easily carried with you, doesn’t need the sun, doesn’t weigh much and is infinitely re-chargeable. 

It’s certainly not the first wind-up charger but it’s definitely the best looking – this is one design concept that I hope makes it to product.
