Abstract: A hydroelectric power plant uses a plurality of windmills connected to compressed air generators to produce pressurized air. Pressurized air is used to drive water through a turbine to produce electrical power. The water is recycled and the power plant includes reserve pressurized air tanks to allow the plant to continue to operate when the wind levels are not sufficient to produce high pressure air. The power plant is designed to be operated on a continuous basis based on wind power. When the wind subsides and the reserve capacity has been exhausted, electricity can be drawn from the local utility supplier. When excess power is generated by the power plant, electricity from the power plant can be added to the grid of the local electricity supplier.

Abstract: Fluid current induced vibrations, as well as vortex shedding vibrations induced in a cable stay or a similar elongated, cylindrical element are dampened and substantially eliminated by applying a plurality of flexible active or passive damper bands to the cable at spaced intervals. In underwater currents, the damper bands force or channel the fluid flow over a circular cross-sectional shape, which inhibits lift, and therefore damps the cable stay oscillations. These damper bands can be retrofit to existing cables or can be installed on new cables. Each damper band may include a shiftable mass and an energizing device for facilitating assisted shifting of the mass. A control assembly can actuate all or selected ones of the energizing devices in response to sensed magnitudes of cable stay vibration.

Abstract: A system for the mitigation of cable stay vibrations, typically induced by wind and rain, utilizes a plurality of active damper bands positioned along the cable stay. Each damper band includes a shiftable mass and an energizing device for facilitating assisted shifting of the mass. A control assembly can actuate all or selected ones of the energizing devices in response to sensed magnitudes of cable stay vibration.

Abstract: Wind/rain induced vibrations, as well as vortex shedding vibrations induced in a cable stay or a similar elongated, cylindrical element are dampened and substantially eliminated by applying a plurality of flexible damper bands to the cable at spaced intervals. The damper bands break up the formation of rivulets of water at lower wind speeds. These damper bands can be retrofit to existing cables or can be installed on new cables.
