VIADUCT Russian patent published in 2016 - IPC E01D12/00 

FIELD: energy.

SUBSTANCE: invention can be used for electric power generation. Shaft is installed on bearings in support projections. Attached to the shaft end are two blades. A gear-wheel is fixed on the shaft. Electric generator with stator and armature is attached to ledge. A gear-wheel is fixed on the shaft, contacting another gear-wheel. Around blades there is semi-circular casing. Shed having side wall is connected on posts to one side of span opposite shaft. Wind pushes blade. Since opposite blade is located behind casing, wind force is not affecting it. One gear-wheel sets into rotation the other. On stator voltage is formed, which is transmitted by wire through span to power transmission line.

EFFECT: proposed design of viaduct generates electric power in summer.
