Inmates in Brazilian jail cycle to freedom

In this Friday, July 6, 2012, inmates pedal stationary bikes to charge car batteries at a prison in Santa Rita do Sapucai, Brazil. An innovative program allows inmates at this medium-security prison to shave days off their sentence in exchange for riding stationary bikes hooked up to converted car batteries that are used to illuminate Santa Rita do Sapucai's town square.
