Who invented tidal mills




















When the tide came in, their wheels would be pushed in one direction; when the tide went out, in the other. But the form of the tide mill that came to most widely applied was more complex. It required impounding the water of incoming tides by means of dams and gates placed across the mouth of a river, creek, or bay.

The gates would be open to an incoming tide, but closed when the tide went out, creating large tidal reservoirs. The water from these reservoirs would then be released through a mill race onto the blades of a water wheel.

Tide mills were not as convenient as conventional watermills. They could be used only six to ten hours a day, and the hours when they could be operated varied from day to day as the tides changed. But where conventional mills could not be used, they were applied, and they did have the advantage of never freezing over. On the opposite side of the street was a grist mill of the old style, owned by Ebenezer Tileston and my father.

The power was furnished by the incoming tide which flowed into the pond and closed the gate when it receded. My father was the miller and worked in the night or daytime according to the ebb and flow of the tide.

Memoirs of Henry N. Edited by Vivian A. Politically all the Hayfords were Republicans. Tide mills are first recorded in the Persian Gulf. The earliest known mill was built in The Netherlands at Zuicksee. The first tide mill in France is recorded at Veulves, Normandy. The idea of constructing a tidal power plant on the Rance is first raised by Gerard Boisnoer. The Rance Tidal Power Station enters construction. La Rance, a MW tidal barrage, generates its first electricity.

The committee decided the project could only proceed if federal funds were allocated and Roosevelt himself commissioned seven million dollars the maximum possible without congressional approval for the project through the Public Works Administration.

Eventually the project was stopped when Congress refused further funding, but the idea has remained in the minds of the people of Maine ever since. In , the project was again considered by an international cooperative between the United States and Canada. The cost analysis showed that the project would only benefit the United States and so the project was again sidelined.

In , Canada undertook yet another study of the bay, but again decided that the project was not beneficial, though it was deemed cost effective.

Today, progress is halted mainly by the large impact such a project will have on the ecology of the bay. It is not clear how extensive the impact will be, but it is likely to be substantial enough to affect the lucrative fishing industry that thrives in that region.
