... so we're going to use them to generate electricity, say Australian scientists.

Australia is to generate electricity using over-ripe bananas. Researchers at the University of Queensland say that bananas can be fermented in giant steel vats to produce electricity.

Every year 50,000 tons of bananas from tropical areas in northern Queensland are deemed unfit for human consumption. Currently they are used as cattle feed or fertiliser.

Successful trials of the combined heat and banana plants suggest that the bananas could provide electricity for around 800 households.
