Bananas could soon be used to power people's homes in Australia.
Engineers have created an electricity generator fuelled by rotting bananas, and hope to build a full size fruit-fired power station.
At the moment most of Australia's banana crop goes to waste, because the fruit are too bruised or too small to be sold in shops.
Researchers want to use the leftovers to build a power plant capable of powering 500 homes.
A lot of bananas
But Dr Bill Clarke, from the University of Queensland who is doing the research, admitted that it takes a lot of bananas to generate a small amount of power.
He said: "60kg of bananas are needed to power a household appliance such as a fan heater for 30 hours."
It will be known by February next year if the bananas can be used as an alternative source of energy.
