The Phillips Machine may, in this era of super-computers modelling the economy, appear an outdated artefact. However, when it was first unveiled at the London School of Economics in 1949 it caused a sensation. The Phillips Machine is a model of the economy which uses water, pumps, valves and, in the case of the original, an electric motor scavenged from the windscreen wiper of a Lancaster bomber. For some photos of a Phillips Machine at the Science Museum, follow the links below:

Chris Anderson, the editor of Wired magazine, has developed a thesis called freeconomics which postulates that this trend will increase and that firms that don’t join in will go to the wall. “As much as we complain about how expensive things are getting, we’re surrounded by forces that are making them cheaper,” Anderson wrote in a recent article.
