Towerkill
Towerkill is a phenomenon in which birds are killed by collisions with antenna towers. In poor visibility, birds may simply fly into the guy-wires. But night illuminations around the towers can also disrupt migration patterns, with disoriented birds colliding with the structure. Research indicates that blinking lights can reduce deaths without diminishing visibility by aircraft. Overview In the United States, the US Fish and Wildlife Service estimates that between 4 and 50 million birds are killed each year by tower kill. The effect on overall bird populations by towerkill may be small, but the phenomenon is of considerable concern to ornithologists, because many endangered bird species are being killed, and because so many birds are killed in such a small area of land. In at least one instance, several thousand birds were killed at a single tower in one night. Additionally, the unnatural lights on communication towers disrupt bird migration patterns in ways that are still not ful ...

Radio Masts And Towers
Radio masts and towers are typically tall structures designed to support antennas for telecommunications and broadcasting, including television. There are two main types: guyed and self-supporting structures. They are among the tallest human-made structures. Masts are often named after the broadcasting organizations that originally built them or currently use them. In the case of a mast radiator or radiating tower, the whole mast or tower is itself the transmitting antenna. Terminology The terms "mast" and "tower" are often used interchangeably. However, in structural engineering terms, a tower is a self-supporting or cantilevered structure, while a mast is held up by stays or guys. Broadcast engineers in the UK use the same terminology. A mast is a ground-based or rooftop structure that supports antennas at a height where they can satisfactorily send or receive radio waves. Typical masts are of steel lattice or tubular steel construction. Masts themselves play no part in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hillmorton Radio Masts
Hillmorton is a suburb of Rugby, Warwickshire, England, around south-east of Rugby town centre, forming much of the eastern half of the town. It is also a ward of the Borough of Rugby. Hillmorton was historically a village in its own right, but was incorporated into Rugby in 1932. Hillmorton also encompasses the Paddox housing estate to the west of the old village, which is shown on many maps as 'Hillmorton Paddox', this area however is part of a separate ward called 'Paddox'. History Settlements in the Hillmorton area spread into the prehistoric era. Archaeological digs at near Ashlawn Road in 2017 found remains of human settlement dating back to the Bronze Age (1000 – 500 BC), as well as numerous finds of occupation from the Roman period, including items of pottery and the remains of pottery or tile kilns. Before Rugby spread to the east, Hillmorton was a village. The village was formed by amalgamation of two settlements: ''Hull'' and ''Morton'': The former being the part ...

Towers
A tower is a tall structure, taller than it is wide, often by a significant factor. Towers are distinguished from masts by their lack of guy-wires and are therefore, along with tall buildings, self-supporting structures. Towers are specifically distinguished from buildings in that they are built not to be habitable but to serve other functions using the height of the tower. For example, the height of a clock tower improves the visibility of the clock, and the height of a tower in a fortified building such as a castle increases the visibility of the surroundings for defensive purposes. Towers may also be built for observation, leisure, or telecommunication purposes. A tower can stand alone or be supported by adjacent buildings, or it may be a feature on top of a larger structure or building. Etymology Old English ''torr'' is from Latin ''turris'' via Old French ''tor''. The Latin term together with Greek τύρσις was loaned from a pre-Indo-European Mediterranean language, ...

Archive
An archive is an accumulation of historical records or materials – in any medium – or the physical facility in which they are located. Archives contain primary source documents that have accumulated over the course of an individual or organization's lifetime, and are kept to show the function of that person or organization. Professional archivists and historians generally understand archives to be records that have been naturally and necessarily generated as a product of regular legal, commercial, administrative, or social activities. They have been metaphorically defined as "the secretions of an organism", and are distinguished from documents that have been consciously written or created to communicate a particular message to posterity. In general, archives consist of records that have been selected for permanent or long-term preservation on grounds of their enduring cultural, historical, or evidentiary value. Archival records are normally unpublished and almost alway ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Wind Energy Association
The American Wind Energy Association (AWEA) is a Washington, D.C.–based national trade association formed in 1974, representing wind power project developers, equipment suppliers, service providers, parts manufacturers, utilities, researchers, and others involved in the wind industry. AWEA promotes wind energy as a clean source of electricity for consumers in the U.S. and around the world and has around 1,000 member organizations. The group was succeeded in January 2021 by the American Clean Power Association. Legislative efforts AWEA staff lobby the U.S. Congress to promote policies encouraging investment in wind energy and provide statistics and data on the wind industry. Additionally, they make policy recommendations and testify on various issues. AWEA supports policies which it asserts will generate investment in the U.S. economy, improve U.S. energy security, and slow climate change, including extension of the federal Production Tax Credit (PTC) and Investment Tax Cre ...

American Bird Conservancy
American Bird Conservancy (ABC) is a non-profit membership organization with the mission of conserving wild birds and their habitats throughout the Americas. Its focus is on threats to birds in the Western Hemisphere – threats which include overuse of pesticides, urban sprawl, habitat destruction, and invasive species. ABC is the second BirdLife International partner in the United States and works in cooperation with other groups and agencies, including The Bird Conservation Alliance, Partners in Flight, and the North American Bird Conservation Initiative. Overall, ABC’s network spans 15 countries and protects over a million acres – benefiting birds large and small.

Wind Turbine
A wind turbine is a device that converts the kinetic energy of wind into electrical energy. Hundreds of thousands of large turbines, in installations known as wind farms, now generate over 650 gigawatts of power, with 60 GW added each year. Wind turbines are an increasingly important source of intermittent renewable energy, and are used in many countries to lower energy costs and reduce reliance on fossil fuels. One study claimed that, wind had the "lowest relative greenhouse gas emissions, the least water consumption demands and the most favorable social impacts" compared to photovoltaic, hydro, geothermal, coal and gas energy sources. Smaller wind turbines are used for applications such as battery charging for auxiliary power for boats or caravans, and to power traffic warning signs. Larger turbines can contribute to a domestic power supply while selling unused power back to the utility supplier via the electrical grid. Wind turbines are manufactured in a wide range of ...
