The hydraulic generator includes a first structure; a second structure, such that a water passageway from the inflow port to the outflow port is formed by the first structure and the second structure in a state that the second structure is attached to the first structure; a water turbine; and an electrical generator. The second structure is removable from the first structure, and includes a fixing portion fixing the fixed shaft.

The present invention teaches a tower for hydropower, comprising a main structure comprising an outflow tank at a top end and a collection tank at a bottom end of the main structure; a transmission device configured in the main structure; a plurality of water basins configured on the transmission device;

and a generator device is coupled to the transmission device. Water is introduced into an outflow tank, and then into water basins so that the water basins are pulled downward by gravity so as to convert potential energy into kinetic energy that drives a transmission device and a generator device to produce electrical energy. Through this simple tower, a limited amount of water is used for electricity generation of enhanced efficiency, with fast initiation and low operating reserve.

Aquatic curtain devices and methods for forming waterway channels and reducing waterway maintenance are disclosed. Each curtain device comprises an elongated float and an elongated flexible curtain depending from a first side of the elongated float. The curtain has a bottom end with a weight extending along the entire length of the elongated float. The float is configured to be sufficiently buoyant to support the curtain in an upward direction. Each curtain device is configured for the curtain to remain in a substantially taut state when in use and accommodate fluctuations in water levels, such that the elongated weight remains on the bottom of the waterway while the elongated float remains on the surface. Artificial channels are constructed by selecting the length of the elongated float to achieve the desired channel dimensions using two or more curtain devices positioned along a desired path in a waterway.
