Power From Sea Waves.

At a recent meeting of the British association the question of economical production of power from tides and winds was under discussion, and it has been taken up widely by scientific journals in Europe. In Francs attention has been called to a system of utilizing the power of sea waves to actuate a dynamo which has been employed for some time past at the mouth of the River Gironde. An airchamber Is connected with a well which communicates with the sea at a depth below the level of the lowest tides. By the advance and recession of the waves changes of pressure are produced in the air-, chamber, and a system of valves enables the resulting air currents to be applied to rotating a kind of turbine. It is reported that the apparatus works equally well in calm and stormy weather. —Harper's Weekly.
