Cow power

A cattle farmer watching his cows grazing decided that all that mooching about is just wasted. Cows, like children, should be put to work. So he puts his cows in an energy generating treadmill set up…

“It’s not as crazy as it sounds. Cows already spend up to 8 hours a day milling around while grazing. Taylor just sticks the cows on a treadmill for part of the time. The farmer’s prototype treadmill can generate two kilowatts, or enough energy to power four milking machines. Cows that exercise are also thought to produce more milk.”

Rooney’s energy could produce 16 cuppas
The energy generated by British soccer dynamo Wayne Rooney as he sprints around the pitch during a match is enough to boil water for 16 cups of tea, according to research published.
David James of Sheffield Hallam University’s Centre for Sports Exercise Sciences calculated the 21-year-old Manchester United and England striker produced 6,700 kiloJoules of energy, equivalent to 1.86 kilowatt/hours of electricity.
This, he said, was also enough to light an average house for 90 minutes – the length of an average match – or run a standard television for six and a half hours.
The research for energy utility E.ON UK is part of a program to try to raise awareness in schools of energy usage in the face of the global warming crisis caused by burning fossil fuels for power and transport.
