New Use For Uv Lamps! Putting It On A Power Line Reduces Bird Collisions By 98 Percent
EDM International, a provider of sustainable solutions for the U.S. power industry, has developed a system that USES ultraviolet light to prevent birds from hitting power lines and reduce collisions by 98 percent.
James Dwyer and his colleagues at EDM International have developed a Avian Collision Avoidance System (ACAS), in which ultraviolet lights are installed in power-line bracing structures and lit at night.
They tested the system at the Iain Nicolson Audubon Center in Nebraska, where a power line crosses the Central Platte River, a key habitat for migrating sandhill cranes. Each night, they randomly switched on and off collision avoidance systems to observe the behavior of sandhill cranes flying along the river at dusk and at night.
As a result, recorded data showed that sandhill cranes had 98 per cent fewer collisions with power lines and 82 per cent fewer dangerous flights during the anti-collision period. At the same time, sandhill cranes react faster and make more controls to avoid hitting power lines.
Dwyer said he has studied bird-power line collisions across North America for several years, involving many birds and bird families, and has even studied wires modified to industry standards to reduce bird collisions.
Dwyer hopes ACAS could be used on other power lines and communication towers to investigate whether the system would work equally well on other species, habitats and wire configurations. If the ACAS research proves broadly effective, he hopes the crash-avoidance system could be easily used by the global power industry.
