This 16-year-old from Somerset invented a hamster-wheel-powered phone charger as a school project.
Peter Ash, of Lawford, Somerset, attached a generator to his hamster's exercise wheel and connected it to his phone charger…
He came up with the idea after his sister Sarah complained that Elvis was keeping her awake at night by playing for hours on his exercise wheel.
"I thought the wheel could be made to do something useful so I connected a system of gears and a turbine," he said.
"Every two minutes Elvis spends on his wheel gives me about thirty minutes talk time on my phone."
