Frugal innovation: the quiet revolution that is fighting off inequality

A man looks at lightbulbs filled with water as part of the exhibition "Lagrimas de Sao Pedro" (Tears of Saint Peter) by Brazilian artist Vinicius Silva, at a cultural center in Rio de Janeiro, March 21, 2013. The artist used six thousand lightbulbs to create the idea of rain, showing the relationship between peasants and rain after singing and praying for Saint Peter to cry. International Water Day is held on March 22. REUTERS/Pilar Olivares(BRAZIL - Tags: SOCIETY TPX IMAGES OF THE DAY) - RTR3FAMV
