Utilization of water

* Utilization of water(water wheel) *
Around B.C. 70, there was a record that Roman people used water wheel to mill flour.
Before Christ, people in west Asia began to use water wheel. And water wheel began to be used in all over the Europe around 1000.
There are two kinds of water mill. One is that water flows under wheel and the other is that water flows over the wheel.
The latter one is more effective since the float board get stronger water pressure.
