It seems Google are not content with just 'organising the world's information'. They're now branching into developing clean energy technology to help address climate change.
They're taking the Toyota Prius hybrid car as a start and further developing this by plugging them into solar charging stations, and then using Vehicle to Grid (V2G) technology to demonstrate how electricity might be transmitted back and forth between the plug-in-hybrid and the electricity grid.
The performance data so far looks pretty good. The plug-in-hybrid Toyota Prius is getting 73.6 MPG as opposed to 40.9 MPG for the standard Toyota Prius, and the CO2 emissions has gone down from 0.577 CO2e/mile to 0.376.
