Amazing Kiwi Invents Hydraulic Computer
New Zealander, Bill Phillips, designed and built an incredible machine over 60 years ago.
The MONIAC (MOnetary National Income Analogue Computer), was one of the world's first computers designed to simulate economic activity. Separate water tanks represent households, business, government, and export/import sectors.
Simulation experiments with fiscal and monetary policy and exchange rates can be carried out by controlling the water flow. Fascinating!
