The Phillips Machine may, in this era of super-computers modelling the economy, appear an outdated artefact.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.
