A hydrokinetic system for generating electricity from hydropower, the system comprising a floatable or floating structure for mooring, the structure comprising: a generally horizontal rotor (12); a deflector (13, 15) for deflecting impinging water to an undershoot flow-path and to an overtopping flow-path to rotate the rotor; and a generator for generating electricity from rotation of the rotor. Networking of the system is also described, as is an anchor for mooring and a method of mooring.

1. A hydrokinetic system for generating electricity from hydropower, the system comprising a floatable or floating structure for mooring, the structure comprising: a generally horizontal rotor;a deflector for deflecting, while the system is in use, impinging water to rotate the rotor, wherein the impinging water is deflected to: (i) an undershoot flow-path, or (ii) the undershoot flow-path and an overtopping flow-path;a movable member, the movable member comprising fore and aft movable members defining respective fore and aft overtopping reservoirs adjacent respective fore and aft sides of the rotor; anda generator for generating the electricity from rotation of the rotor;wherein when the impinging water is deflected to the overtopping flow-path, the impinging water is directed to a fore overtopping flow-path when water impinges from a fore direction and to an aft overtopping flow-path when water impinges from an aft direction, the fore and aft overtopping reservoirs for collecting water deflected along a respective one of the fore or the aft overtopping flow-paths to provide a hydrostatic head acting on the rotor. 2. The system of claim 1, wherein the deflector comprises a top surface for deflecting water to the overtopping flow-path, and a bottom surface for deflecting water to the undershoot flow-path. 3. The system of claim 2, wherein the deflector is elongate along a longitudinal axis and has a triangular cross section to define the top and bottom surfaces. 4. The system of claim 3, wherein the deflector is mounted with an apex facing away from the rotor and with a side of the deflector facing the rotor, the longitudinal axis of the deflector being generally parallel to a rotational axis of the rotor. 5. The system of claim 4, wherein the deflector comprises an irregular triangular cross section with a shortest side in cross section facing the rotor, a longest side in cross section defining the bottom surface and a remaining side in cross section defining the top surface. 6. The system of claim 1, wherein the deflector comprises a fore deflector to deflect water impinging from the fore direction to the fore overtopping flow-path and an aft deflector to deflect water impinging from the aft direction to the aft overtopping flow-path. 7. The system of claim 1, wherein the movable member is movable between a closed position in which water deflected along one or both of the fore or aft overtopping flow-paths is collected in a respective one of fore or aft overtopping reservoirs, and an open position in which water deflected along one or both of the fore or aft overtopping flow-paths is permitted to flow past a respect one of the fore or aft sides of the rotor. 8. The system of claim 1, wherein the movable member comprises a louvre door. 9. The system of claim 8, wherein the system comprises a plurality of fore and aft louvre doors. 10. The system of claim 1, wherein the deflector comprises a hollow outer body having packing material disposed therein. 11. The system of claim 1, comprising a debris screen mounted to intersect the overtopping flow-path. 12. The system of claim 1, wherein said structure comprises first and second pontoons bridged by the rotor. 13. The system of claim 12, wherein the first and second pontoons are further bridged and connected by fore and aft deflectors each for deflecting impinging water to the undershoot flow-path and to the overtopping flow-path. 14. The system of claim 12, wherein one of said pontoons comprises the generator and the other of said pontoons comprises one or more of: an electrical inverter, an electrical transformer, an electrical breaker, or an export power cable junction box. 15. The system of claim 12, wherein at least one of said pontoons comprises a device for generating fresh water from higher salinity water.
