The power-saving invention of a London schoolboy is being presented to the UN climate change conference in Copenhagen.
Fifteen-year-old Robert Appleton has designed a system to power street lighting by using speed humps. His blueprint was to be handed over to the Danish Prime Minister in a special ceremony at the conference this weekend.
He first came up with his so-called Powerbump invention at a climate camp for young people in Sonderborg, Denmark, in August.
More than 500 teenagers from around the world had been asked to brainstorm ideas for greener energy, the BBC reports.
His group devised a new system to power street lamps, channelling energy from cars driving over special speed bumps rather than connecting them to the national electricity grid.
Robert Appleton believes that just one car could generate enough energy to power a light bulb for around nine hours.
