The UK energy demand could be satisfied by the power generated from screams of the country’s population – at least in theory – a study by Leicester University students has proven.
Inspired by the Disney and Pixar film Monsters Inc, where characters Mike Wazowski and Sulley use a device called the Scream Extractor to gather screams of children to power their hometown Monstropolis, the students set out to calculate how many screams would be required to power a country the size of the UK.
They found that every individual inhabitant would have to scream 2,800,000,000 times a day in order to generate enough power.
Moreover, the screamers would have to be quite loud and achieve the level of 129 dB with each scream, which is believed to be the limit of the abilities of the human voice. Each such energy-generating scream would have to least two seconds.
Student Osarenkhoe Uwuigbe arrived at the conclusion by calculating the average daily electricity consumption, estimated at around 125 kWh, and multiplying this value by the recorded population of 64.1 million.
The results were published in the Leicester University’s Interdisciplinary Research Journal that published the findings.
“An important part of being a professional scientist (as well as many other professions) is the ability to make connections between the vast quantity of information students have at their command, and being able to utilise the knowledge and techniques they have previously mastered in a new or novel context,” said Dr Cheryl Hurkett from the University of Leicester’s Centre for Interdisciplinary Science who oversaw the study.
