This week's podcast looks first at the growing problem of global electronic, or e-waste. Then, to India to look at the launch of the Tata Nano, billed as the world's cheapest car. Also, an in-depth look at how the internet is changing the way people buy, or don't buy, music. And finally, we step back in time to look at the old school technologies that go into making cymbals. Too cool. I can't believe we give this stuff away!
