Copper Speeds Commerce, Saves Money in RFID Antennas
Rapidly advancing technologies ensure a role for copper in future RFID (RF identification) systems.
Hemispherical Copper Domes in Architecture
Hemispherical copper domes create art in architecture. This paper discusses the design benefits of self-supporting copper domes, their design flexibility and examples showing their wide range of applications in the field.
Motor Upgrades Help Cut HVAC Energy Costs at Emory University
Emory University, located in Atlanta, is a recognized center for biomedical research and home to some 11,000 students. Keeping its students and laboratories cool requires more than 25,000 tons of air conditioning with an energy bill of $2.5 million per year. Use of premium-efficiency motors in HVAC equipment helps keep energy costs down. So far, Emory"s power bill for chillers has been cut by 10% and it expects to double that in the future.
Copper Corrects Power Quality Problems in Columbus, Ohio, High-Rise Office Tower
Recurring problems vanish when copper replaces aluminum feeders: Built in 1982, Capitol Square and its electrical system served its early occupants well. Until, that is, growing loads and some false economizing taken at the time of construction caught up with the original system. By the time the new owners took over management of the builidng in 1998, the old wiring system had begun to cause noticeable problems.
Copper Checks in @ Internet Hotel
The Downtown Phoenix Telecom Exchange (DPTE) houses a 380,000-sq ft (35,300 sq m) Internet hotel in the former offices and printing plant of the Arizona Republic. We donï¿½t see the power in use because much of the action takes place behind locked doors in unremarkable, often windowless buildings called Internet data centers (IDCs), also known as telecom exchanges or collocation centers and, less formally, as Internet hotels, server farms and carrier condos. Theyï¿½re home to all sorts of Internet-related companies, through whose servers, routers and modems flow the bits and bytes of modern e-commerce. Restructuring the 50-year-old building for its new role meant replacing the entire electrical system with a modern, 100% copper system designed to ensure maximum power quality and reliability.
Kodak Focuses on NEMA Premium Motors
Kodak Park, the international photo giantï¿½s main research and manufacturing facility in Rochester, New York, is one of the worldï¿½s largest industrial technology centers: the 100-year-old complex covers eight square miles, contains 20 million square feet of buildings, hundreds of miles of roads and 22 miles of railroad track. Two power plants with a combined capacity of 200 MW generate most of the electrical energy the facility consumes annually. Photo giant"s Total Motor Program saves at least $250,000 per year by installing high efficiency motors whenever possible, irrespective of size. Kodak is cutting energy consumption by applying a lot of smart engineering, but a large portion of the savings comes as a result of a company-wide program that focuses on its electric motors.
Copper Motor Rotor Project
The incorporation of copper for the conductor bars and end rings of the induction motor in place of aluminum would result in attractive improvements in motor energy efficiency. Lack of a durable and cost effective mold material has been the technical barrier preventing manufacture of the cast copper rotor. This project seeks to identify mold materials for copper pressure die-casting that will allow economical production of copper motor rotors.
Innovations was developed to cover technological changes involving copper.
