DIY electricity

Here's an article from The Economist that discusses a sustainable source of electric energy that we generate all the time: walking around. In parts of the developing world not connected to the electric grid, this may offer a means of providing the energy needed to power, for example, lanterns, medical devices and radios. This could conceivably reduce the need for relatively expensive and carbon-emitting fuels such as kerosene and firewood, and increase access to reading light and informative radio broadcasts. And of course we here at Think Globally Radio like the idea of more people listening to the radio.
