NOVELTY - The waterwheel (1) has a cylinder (4) covered by lids (5) on the sides of the waterwheel. A central axle (7) carries two revolving suspensions (10) that support a rotating shaft (11) with a cogged pinion (12) whose cogs fit into an inner cogged ring (13), where the cogged ring mechanically transmits torque either directly or via a gearbox (14) to a generator (15) e.g. pneumatic generator. The produced energy is conducted into an engine room (3) equipped with a control gear (30), a security mechanism (31), a communication apparatus (32) and a meter of produced energy (33).    USE - Floating waterwheel for use as a multifunctional energy generator e.g. electric current generator, mechanical electric energy generator, hydraulic generator, hydrogenerator or pneumatic generator, to produce energy, electricity and heat to drive hydraulic and pneumatic appliances and hydroelectric power plant. Can also be used for an industrial utility, mechanical single-purpose appliance, electric carpet heater, hydraulic multifunctional appliance, propel pump, milling industry, moving timber, floating timber and mechanical jibs for timber handling in forestry field, cableways for towing ships upstream in river navigation field.    ADVANTAGE - The waterwheel with the water current is prevented from drifting by mounting arms of the waterwheel to anchor. The waterwheel performs safety regulations for manipulation of oil near watercourses, so that a hydraulic medium runs in double piping that conducts the leaked oil back to the oil tank, and leakage is electronically monitored by a central security system. The waterwheel enhances service life of an appliance by utilizing hermetic design. The humidity of air inside the waterwheel to be replaced is eliminated by gas so that corrosion of the appliance is avoided. The waterwheel achieves low-cost ecological production of electric energy.
