<p>A tethered buoy system generates compressed air from the motion of the floating ring 6 relative to the main body 9 and the tension induced in the mooring and anchor lines 11 and 12 by the spring piston 10. This compressed air is fed into the bottom of the vertical tube 23. Passage of the air through the tube 23 induces a flow of water up the tube to the surface layer. As a result of this action aeration occurs and a movement of water from the lower level to the surface layer. The main body 9 houses bellows (4, Fig. 2) which are caused to alternately expand and contract through oscillation of float ring 6 thereby forcing air via one-way valves (8, Fig. 2) into the air lines 14. In an alternative arrangement the bellows are driven by a pulley wheel (16, Fig. 3) over which runs the mooring line 11. <IMAGE></p> |
