Abstract: A hydropower system for a body of water that may comprise a fluid intake positioned below a bed of the water body and immersed in a filter below the bed, wherein fluid flows from the water body through the filter into the fluid intake. The hydropower system may further comprise a tunnel with a first end in fluid communication with the fluid intake and a second end in fluid communication with a hydropower generator, and a fluid outlet in fluid communication with the hydropower generator.

Abstract: A monitoring system measures the tensile load on a ship's rode (the cable, chain or rope connecting the ship to its anchor) and also measures the velocity and direction of the wind and the velocity of the current that produce the rode load. From those measured values, the system calculates wind and current resistance factors enabling it to model rode load as a function of wind and current velocity. When the behavior of the monitored rode load departs from the behavior predicted by the model in a manner that is symptomatic of a catastrophic or dragging anchor system failure, the anchor monitoring system signals an alarm. An alarm is also produced if the rode load approaches the tensile strength of the rode. The system also tests the anchor holding strength of the sea bed and provides anchor load information helpful to a skipper when motoring into the wind. The monitoring system senses rode load by using a load cell to laterally deflect the rode.
