A bus by the name of "Tindo" has debuted in Australia, carrying with it the pretty hefty title of "world's first solar-powered electric bus." This free-ride, air-conditioned 42-passenger bus is powered by 11 zebra sodium-nickel batteries that can provide the big green bus 124 miles worth of travel on a full charge.

Unfortunately, this bus still has to be plugged in, even though it's solar-powered due to a lack of available roof space to hold the huge number of solar panels necessary to independently charge it. The bus station will be retrofitted with solar panels that will charge the bus when docked.

Adelaide, the city down under host to this bus is no stranger to the sun. It was also the finish line for the 2007 World Solar Challenge back in October. Crikey! [Treehugger]
