The ball is the brainchild of four girls from Harvard, who wanted to improve the lives of people in parts of the world where electricity is scarce — including African countries where 95% of the population is living with no access to electricity. The World Bank estimates that breathing the fumes created from burning kerosene indoors (the energy source many use there) equals the harmful effects of smoking two packs of cigarettes a day.
Enough energy can be generated to power a lamp for three hours after playing soccer with this ball for just 15 minutes.
