Tindo Solar Bus

The world's first solar-powered electric bus, Tindo was launched in 2007 in Adelaide, Australia. Not only is the bus fuel-free, but passengers can ride it for free! It's also a pretty cool ride — literally. The bus is air-conditioned and can carry as many as 40 passengers. It's also a WiFi hotspot, another free service.

According to the city of Adelaide, the bus has saved the environment over 70,000 kilograms of CO2 emissions annually.
