This is a great series of uplifting stories about real wealth creation, and new solutions to old problems: e2-series
Click on webcasts for the full episodes, but note that they apparently turn them off a while after broadcast.
Having watched them all now, I recommend watching them in this order:
- Transport eps.
- Melbourne reborn
- Harvesting the wind
- A garden in Cairo
- The art and science of Renzo Piano
(then the rest in any order)
