A cat, algae and a small snake

A few years ago I was asked to coach the contestants in a pitching contest for one of the big oil companies. The goal of the pitches was to present new, greener energy sources. For one of the participants I was able to come up with a shrewd plan involving a prop.

A prop can be anything you bring to the presentation for demonstration purposes, but don’t take this too far. I once saw a man who brought a cat to a presentation in order to demonstrate the mechanics of it landing on its feet. The cat was not happy. You can guess how it ended. It’s amazing how fast a cat can move its claws when it is properly motivated.algae

Anyway. William, my student, came on to the stage carrying a glass that was filled with something that looked like algae in water. ‘Ladies and gentlemen, he said, I would like to present to you algae, the biofuel of the future!’ and he held up the glass. The audience were properly impressed and William put the glass down and floated fluently through his presentation, describing the many benefits of his idea with great confidence.

When he got to the end though, he appeared to be making a dreadful mistake. He said: ‘I am sure that this fast-growing green fuel will be available in every service station in less than five years. I’ll drink to that!’ And he set the glass to his lips. The audience, who had been quite captivated, jumped up and shouted: ‘No, no, no! Stop, you fool! You can’t drink that!’ And William smiled and said: ‘Yeah yeah, don’t worry. It’s lemonade … Cheers!’ Needless to say that William won first prize.

Props can be really helpful if you do something with them. Don’t just stand them on a desk or they will be very distracting (unless they are a glass of lemonade). The more spectacular looking props are best kept hidden until you need them. Show them when you do – and make sure everybody can see them – and then put them away again. I remember a biologist who left a small snake lying on the desk just for decoration. To this day I still have no idea what his talk was about and I am guessing nobody else in the audience do either. Something to do with snakes, probably…

Communicate Technology

Helping students to write and present technical reports.


This blog was initially created to help my students at Delft University of Technology write and present better technical reports. It turns out that a lot of people who are not my students are reading my posts too. Cool! I hope you find what you need and that you enjoy reading my blog.

What do you mean with “better technical reports”, you may ask. Better means: more geared to your readers’ needs and wishes.  So, all we need to do is find out who your readers and listeners are, find out what they need and wish and then find ways to deliver.

Easy? Hardly. The tricky thing about professional reports is that they are all read by several different people who all have different expectations from the same report. The fact that the reports that we write deal with technology adds an extra layer of challenges to this.

Presentations also, are usually attended by mixed audiences. Some people will be experts in your field, some will not. Some people will expect pictures, some people will expect numbers. And it’s you job to decide on a good mix.

In this blog  I will post anecdotes, examples, exercises and ideas dealing with writing and presenting  about technology. Please feel free to leave comments and questions.

Punch those keys!
