The Trolley:
The O-range Generator Trolley is the result of O-Range's five years lasting development in the energy independence field. Heart of the system is the patented trolley wheel which acts as a dynamo and produces clean electricity whenever it is rolled. The simple act of pulling the trolley automatically produces electricity which is stored in the O-range battery unit. This stored energy can later be used to recharge or power all types of personal electronics such as mobile phones, GPS devices, Palm, iPhone, iPod, music players and even small laptops. Adapter for common electronic devices are included.
100m rolling the trolley is up to two hours of music ...
