<p>To take advantage of the rising tide, a floating body rises, this body having toothed plates which are guided by rails and turn gear wheels. These gear wheels transmit rotary power to dynamos on both rise and fall of the tide. The floating body can also create an air pressure and an air suction, corresponding to rise and fall of tide, setting wind blades or wheels in rotation and thence to dynamos. Device uses windmills and oblique roof surfaces for increasing the wind strength. The unit has side wall chambers contg. propellers which respond to pressure and suction, and the water levels at low and high tide.</p> |
