A towing apparatus has a spine with multiple generally parallel spine members extending in a longitudinal direction and having a length of at least 100 m, and with a leading end and a trailing end. A series of blades are mounted to the spine by couplers which allow the blade to rotate about an axis substantially transverse to the longitudinal direction, each blade having a first surface facing generally in the trailing end direction and a second surface facing generally in the leading end direction. Restraints prevent rotation of each blade by more than a pre-set amount towards the leading end, so that impingement of a wave on the first surface applies a force to the apparatus in the leading end direction. A pair of the towing apparatus' may be arranged to connect to a floating collector with a beach shape to collect floating debris on the sea surface, ridges helping to retain the debris on the slope until it is washed up into a channel.

Wave-powered towing apparatus

A wave energy converter has blades () on frames () rotating about a pivot joint () on a structure (). There is reciprocating rotary motion of the frame with respect to the structure, providing reciprocating rotary input power to a mechanism (). The mechanism () may be arranged so that the reciprocating input power is transferred to uni-directional power via pulleys () and sprag clutches ().

Wave energy convertor

A non-woven mat of inorganic fiber is disclosed having a substance which is lower at the edges of the mat than in the remainder of the mat. Apparatus for making such a mat includes: a source of a slurry of inorganic fiber in a liquid; a forming wire disposed to move past the source, the liquid passing through the forming wire to deposit the inorganic fiber on the forming wire; a mask across a part of the width of the forming wire to hinder passage of the liquid through the forming wire over the part, the effectiveness of the mask varying in the direction of movement of the forming wire past the slurry source. A method of making the mat includes passing a forming wire past a slurry of inorganic fibers in a liquid while masking a part of the width of the forming wire as it passes through the slurry, the masking varying along the length of the forming wire as it passes through the slurry; and urging the slurry against the forming wire and causing the liquid to pass through the forming wire, whereby a non-woven mat of inorganic fiber is formed having an uneven substance (weight/unit area) in the cross direction.
