“The magic washing machine” is a very accessible speech that talks about complicate subjects. It is also one of my favourite TED ones. How does Hans Rosling do it? What are secrets of the way he delivers? Let’s watch it first. Take your notes on the items that make it good.
Here are my notes:
1. The structure: it goes around a (personal) story, it starts and ends with it. He also includes multiple references in the main part. I would draw the complete structure as:
* intro: story: when his family got first washing machine
* income levels in the world
* energy use levels in the world
* future: green energy, less consumption in the rich countries
* ending: personal story (what the washing machine changed in the family life)
2. Illustrations: first is of course the washing machine itself that takes the central place on the stage. He uses it very often. It is especially interesting at the end when he gets books out of it.
His slides are also important and illustrative, but secondary. Note that he has photos and simple diagrams. The diagrams are very easy to understand (people images as billions of people, energy units without any detailed value). The diagrams get directly to the point.
3. Fun: the audience laughts very often. Note that he uses a specific type of jokes: it is based on the contrast by what the audience finds normal and what he presents as normal in some time in the past or somewhere else in the world.
