The London Science Museum plans to exploit the excrement of its visitors to generate electrical energy and thereby reduce its energy bill, announced its director.
"Since 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 large electric bills."
Estimates, based on the figure of 3 million annual visitors, predict that the energy produced would be 1.530 kilowatts / hour, enough electricity to power 15.000 light bulbs each year.
This idea follows the discovery in the United States of a way to exploit the bacteria from excrement to make an energy resource.
The desire to reduce energy costs is already at the heart of the concerns of the Science Museum, which had solar panels installed on its roof last year.
