The Museum of London of Sciences plans to use the excrement of its visitors to produce electrical energy and thereby reduce energy costs, announced its director.
"As the museum is free, it would be a good way for visitors to make a contribution," said John Tucker, director of the museum. "With three million visitors a year, we have important electric bills."
The estimates, based on the number of 3 million annual visitors, provide that the energy produced would 1.530 kilowatts / hour, enough electricity to power 15.000 light bulbs every year.
This idea follows the discovery in the United States a way to use bacteria excrement into a energy resource.
The desire to reduce energy costs is already a central concern of the Science Museum, which was set last year of solar panels on its roof.
