Windup radios already exist and now the company that makes them has created windup light bulbs so people can create their own light!

As part of its LifeLight Project the Freeplay Foundation has drawn up designs for a charging base unit that would be able to power up several detachable lights that can be used around a home.

The Foundation aims to train women to sell and maintain the lights
“They could use them for study or for safety – to help them if they go somewhere at night,” said Ms Pearson.

Working prototypes are now being made that will be tested with families in Kenya to refine the design.
