SYDNEY (Reuters) - Australian scientists have discovered what sportsmen and
women around the world have known for years: bananas are a great source of
instant energy.

A new government-funded study is investigating the possibility of
harnessing bruised or spoilt bananas -- deemed not worth selling to
consumers -- to provide energy for 500 homes.

"It's not a hoax," Australian Banana Growers' Council Chief Executive Tony
Heidrich said on Tuesday.

Reminiscent of the pig-powered town in the futuristic movie Mad Max
Thunderdome, bananas would be combined with bacteria to produce methane.
Pipes would take the gas to a turbine which could be plugged into the main
electricity grid.

"It's like a big stomach. You open the lid, you put the stuff in and seal
the lid and...away you go," said Heidrich by telephone from the nation's
banana-growing state of Queensland.

"Essentially it's just like a big composting bin. It's a waste product and
currently we're not doing anything else with it. This would harness the
electrical capacity that it can bring," he said.

However, Heidrich said other fruit-powered homes, such as apricot,
pineapple or kiwi-fruit, were unlikely anytime soon.

"Initially I think they'll stick to bananas but potentially you could use
other fruit," he said.

Ethanol from sugar cane has already been tested for commercial energy use
and the husks of Australia's native Macadamia nuts have been used as fuel
to make electricity.
