Check out this groovy solar-powered foot bridge:
One of the other unique features of the bridge is how it is lit and powered. The bridge employs a sophisticated LED lighting scheme that can be programmed to produce an array of different lighting effects, which will become a feature of Brisbane’s annual Riverfire celebrations.
75 per cent of the power required to run the LED lighting in the fully lit mode is generated by solar energy, but in most lighting configurations, 100 per cent of the power will be provided by solar with any surplus electricity returned to the main grid. The 84 solar panels used on the bridge will have an average daily output of 100kWh and an average yearly output of 38MWh
Public Works Minister Robert Schwarten said the bridge’s grid connect solar power system will see savings of around 37.8 tonnes of carbon emissions each year.
