There are two categories of bridges: those that pass over an obstacle, a railway, a road, a river and those that cross a valley at high altitude.
The former have relatively low heights.
The latter can have considerable heights, they are road, motorway and railway bridges that connect two slopes at the top through a valley, they are daring works, under which there are huge spaces.
Wind turbines for bridges take advantage of the height of bridges to function at their best.
The bridge supports vehicles, power lines, pipelines of all kinds, and can also support bridge wind generators.
Characteristic of the bridges is safety, in Europe bridges of ancient Rome are still functioning in full safety today.
The patented wind turbines for bridges are mounted under the bridges, they are therefore fixed effectively and securely.
Furthermore, the wind turbines for bridges have no blades and parts that can detach and fall, they are compact and powerful, occupy otherwise unused spaces, are not invasive and are not dangerous for the movement of men and vehicles both on the bridge and under the bridge or for river navigation under the bridge.
The wind turbines are segregated in the bridge and cannot be reached, except by employees.
Bridge wind generators do not need to be installed above the bridge and are not visible above the bridge.
Wind turbines integrated into the bridge do not require significant installation costs.
Even in inaccessible places, it is easy and cost-effective to transport the energy produced by wind turbines on bridges, since there are roads or railways on bridges and electricity is transported through these routes. Furthermore, on the bridges, it is easy to reach the wind generators under the bridges for checks and maintenance.
The patented bridge wind turbines are not conventional bridge-mounted wind generators, but are integrated into the bridge structures and, in some cases, the bridge itself can even be partially integrated into the generator structure.
Wind generators integrated into bridges are sensitive to even moderate winds and produce energy even in light breezes.
Some bridges, especially those close to the sea, are subject to daily breeze patterns.
Finally, a potential mechanical energy storage system can be integrated into the bridge structure.
The energy storage facility on the bridge stores energy from the bridge's wind turbines.
