<p>A conveyor-type apparatus harnesses energy from a fluid flow, for example a river or a tidal flow region, and comprises a support structure, a continuous-loop, flexible driven element, for example a pair of chains, mounted to the support structure and extending along a closed-loop path, the path defining an interior region and an exterior region, and a series of reversible fluid foils. The driven element has first and second reaches, the first and second reaches being upflow and downflow reaches when fluid flows from the first reach to the second reach. Each fluid foil is connected to the flexible driven element for movement between a first orientation, situated in the interior region when moving along the upflow reach, and a second orientation, situated in the exterior region when moving along the downflow reach. The first sides are generally concave when moving along the upflow reach and generally convex when moving along the downflow reach. The second sides are generally concave when moving along the downflow reach and generally convex when moving along the upflow reach. The driven element may be coupled to an energy generator so to harness energy from the fluid flow.</p> |
