Apart from the high-level discussions, side events at Rio+20 showcase interesting innovations – one of them, that caught my eye, is a football that turns kinetic energy into electricity: SOCCKET.
A 30min football game could power more than 3 hours of light, and a two-hour game will charge a mobile phone, Jessica Matthews, CEO of Uncharted Play, which produces the SOCCKET football, told SciDev.Net.
The ball is built of durable materials with a patented technology packaged at the center of a little black box inside the ball. The ball also lasts for at least three years – much more than an average football, said Matthews.
She was promoting the ball to business people gathered at the Corporate Sustainability Forum, hoping to strike new partnerships to custom-make and distribute the ball to children in poor areas of developing countries.
So far, the football has been distributed to children in Brazil, Costa Rica, El Salvador, Honduras, Mexico, Nigeria and South Africa, but Uncharted Play is looking to expand and reach more of the 1.6 billion people who are currently without electricity.
But at a price of around US$40 it may prove a tough sell.
