FIELD: generation of electric current in small and large rivers. SUBSTANCE: all parts of float propeller are made from rubberized fabric. Propeller consists of elongated inflatable chamber with longitudinal projections and recesses and have form of six-pointed star if viewed from the end; these projections are used as blades over entire length of propeller; propeller is provided with two rings pressed in recesses and embraced by three belts crosswise; if propeller is held by these belts in stream of river, it starts rotating transmitting the rotation through shaft belt to electric generator; other belt from second ring is secured on swivel-bearing at end of thick fishing rod (in large river) or on swivel-bearing on opposite bank (in small river). EFFECT: enhanced efficiency. |
