Link TV's documentary "ViewChange: Unleashing Innovation" highlights the works of top social entrepreneurs tackling problems worldwide such as infant mortality, hunger, disease, clean water, and security from new angles. For example, one grassroots invention described in the film: soccer balls that produce electricity. This innovation is a response to the fact that 1 out of 5 people worldwide lives without electricity; 30 minutes of play with these soccer balls generates 3 hours of light.
