Described is an energy converter for converting rotational energy to mechanical strain energy in flat spiral springs, the converter unit including: an axle for operatively mounting a plurality of spiral springs having inner ends and outer ends; at least a first and second spiral spring module, each module including one or more spiral springs operatively mounted at each inner end to the axle, one or more of the springs in each of the spiral spring modules having their outer ends operatively connected together with a link extending between the first and second spiral spring modules, wherein the arrangement of radial spiral windings in the first and second spiral spring modules are substantially reflected or mirrored across a plane disposed between the first and second spiral spring modules.
A fish pen or sea animal module structure, the fish pen module including a plurality of pipes; a plurality of connector nodes including pipe receivers configured to receive pipe ends from a plurality of directions; the plurality of pipes connected to the connector nodes to form a substantially cubic lattice structure, supported by braces connecting adjacent or opposed pipes. A method for forming a structural module for an aquaculture structure, the method including the steps of: connecting a pipe with other like pipes using a connector node, the connector node being a body with receivers extending in different directions; the arrangement being to form a lattice structure module. There is also described a connector for connecting pipes together in an aquaculture structure, the connector including a body; a plurality of pipe receivers, each for receiving at least a portion of a pipe.
