After my visit to the Zoo yesterday I caught the Adelaide Connector, a free bus, to the railway station.
Tindo takes claim to being the World's first solar electric bus. It carries 40 passengers, 25 of whom are seated, and has a range of 200 km.
It is an electric bus run on batteries that are charged (indirectly) from solar cells on the roof of the Adelaide Central Bus Station. These are connected to the state's power grid which is actually used to charge Tindo's batteries overnight. 70,000 kilowatt hours of electricity is generated annually, sufficient to offset the requirements for charging the bus.
Tindo is the Kaurna Aboriginal name for sun.
