The Energy Ball is a sensible concept that hopes to bring some relief to the ‘chronic shortage of electricity ‘, as is faced by the people residing in the third world especially. Designed by Hwang Sung Hyun and featured at the Red Dot Award 2009, the device converts impact energy into usable electricity; practical enough to allow you power a table lamp or a reading light. The piezoelectric material translates mechanical signals into electrical signals when the ball is dribbled.

So, while you kick it or play with the ball, you are actually creating electricity. Electricity, thus produced, is stored inside the ball to be used to power a light bulb later.
