Hamster-powered phone charger
`A 16-year-old boy invented a hamster-powered mobile phone charger as part of his GCSE science project. [..]
“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.”
The teenage inventor was given a C for his project and has been awarded a D overall for the course.’
