  Poo power could light up museum
Updated 15 July 2004, 08.01
Poo power could light up museum
Bosses at London's Science Museum have come up with an unusual way to save money on electricity - poo power!

Three million people visit the museum every year and museum staff think their waste could help power the building.

There are a couple of different ways poo power could work, and it could make enough power for 15,000 lightbulbs.

Head of the Museum Jon Tucker, 43, said: "with free admission it would be a great way for visitors to give something back to the Museum."

The museum is always looking at new ways to keep bills low and has recently fitted solar panels into the roof.


The idea has come from some new research in the US called microbial fuel cells.

They use electrically charged particles in bacteria from waste to power an electric circuit.

In Australia pig waste is used to power some farms and in Thailand scientists are trying to work out how to make cars powered by our waste.
