100 Solar-powered lamp and charger 22 Oct 2010

Fri, 22 Oct 10

A lamp that runs off sunlight. Neil MacGregor, Director of the British Museum, looks at the final object in the series: a solar-powered lamp with a charger that can bring cheap light and power to people around the world with no access to the electric grid1. Simple, cheap and clean – is this the revolutionary technology of our future? With contributions from Aloka Sarder, a mother and adult student in West Bengal, and Nick Stern2, expert on the economics3 of climate change.
