Warwick Castle in the UK is ensuring that visitors to the attraction stay fully charged and in touch with friends and family during their visit through its new free to use, state-of-the-art mobile phone chargers.

Designed especially for the castle’s 600-year old water mill, the chargers are powered solely by the waters of the River Avon that thunder round the waterwheel.
 
The three custom-made chargers have been installed in the engine room of the Mill and are powered by electricity generated by the waterwheel.

The service is free to visitors and the environmentally-sound chargers take no longer than a standard device.

Visitors can see the waterwheel in operation and learn how the Mill used to grind flour for centuries before being converted to generate electricity and pump water.
