    In electrical applications, aluminum can do everything that copper can, but more efficiently and economically. Aluminum provides up to twice the conductivity per pound of copper (dependent on the specific alloy and application) at less than half the cost per pound (based upon current prices) for a 400% economic-efficiency advantage over copper.

  • For the CSM project, Nexans has supplied 212 km of cable with a single 6 mm2 copper core and 804 km of cable with a single 10 mm² copper core. The cables comprise both standard ENERGYFLEX® and ENERGYFLEX® One Stripe featuring a coloured red or blue strip for ease of identification. The cables were installed at the site between March and June 2010. Schneider Electric has also purchased bare Nexans cable with a copper cross-section of 35 mm² to create the underground cable network for the CSM project.

  • The International Copper Association (ICA) is the leading authority on the fundamentals of future copper demand and substitution. ICA’s portfolio of material demand and substitution work covers global studies, surveys and detailed data sets. Full studies and data sets are used by ICA and its members for market development purposes, and select information is available to market commentators.

  • An international team led by Physics and Chemistry teams from the Faculty of Science and Technology at the University of the Basque Country (UPV/EHU) and directed by Professor Jose Javier Saiz Garitaonandia, has achieved, by means of a controlled chemical process, that atoms of gold, silver and copper - intrinsically non-magnetic (not attracted to a magnet) - become magnetic. The article has been published in the February issue of the prestigious international magazine in nanotechnology, Nanoletters (Vol.8, No. 2, 661-667 (2008).

  • The company's Power-Pipe technology is basically copper tubing that wraps around a residential drain pipe.
  • The company claims the system will pay for itself in two to five years, it can be used in new and old homes, and it can reduce home energy consumption by 5 to 10 per cent. Not bad when you consider the hot water portion only accounts for 20 to 30 per cent of total home energy use.

    Super strong nanometals - a Chinese-Danish success Research shows that it is possible to produce copper about 4 times stronger than commercial material - and doing so while also having a ductile material. As the thermal and electrical conductivity are also good, the manufacturing of, for example, electrical conductors with improved mechanical properties looks promising

  • We found that the EV powertrain is $4.6k cheaper to produce than we thought and there is more cost reduction potential left. Consumer cost of ownership (TCO) parity vis-à-vis combustion engine (ICE) cars can be reached from 2018 (first in EU), creating an inflection point for demand.
  • Our detailed analysis of moving and wearing parts has shown that the highly lucrative spare parts business should shrink by ~60% in the end-game of a 100%-EV world, which is decades away.
  • EVs are an opportunity for tech companies because the electronics content in the Bolt is $4k higher than in an ICE car, excluding the battery.
  • ...3 more annotations...
  • Commodities-wise, we detected the highest deviation in weight shares between the Bolt and ICE car in copper, aluminium, battery active materials and rare earths.
  • Highest impact on markets for aluminium, copper, battery active materials, rare earths (all positive) and platinum group metals (negative).
  • Therefore, the cost difference (not the retail price difference) between the Bolt and the VW Golf, which we consider an equivalent ICE car, appears set to shrink to $2.3k.

  • From the well-proportioned minds of researchers at the University of Washington comes the development of a set of wire-bound sensors that use the existing copper wire in a home to transmit signals to a plugged-in base station. This would allow sensors to be placed in hard to reach and out of the way spaces to detect things like moisture and humidity levels, as well as the presence of Zombies and/or other forms of the undead.

    The secret to producing thin-film solar cells comes in part from the snack food industry, says Ascent Solar. The Littleton, Colo.-based company says it will deploy high-speed thermal evaporators--the same equipment used to seal Doritos bags--to produce copper-indium-gallium-selenide (CIGS) solar cells.

    Allied Wire & Cable's line of Wind Turbine Cable consists of our WTTC rated GreenLINX™ Wind Power Cable. Wind turbine cable requires high quality, durability and high performance to withstand the rigors of wind power environments. Wind turbine cables can be exposed to several different forces, including Mother Nature. Oil, solvent, chemical and fuel resistant, GreenLINX ™ wind turbine cable can withstand these forces and more. Allied carries five different types of wind turbine cable, all part of the GreenLINX™ line of wind power cable. All five types are WTTC, 1000 volt rated, constructed of bare copper conductors.

  • In this work, some fundamental aspects concerning the efficiency of induction machines are treated. The standards and the therein prescribed methods for the determination of the energy efficiency of induction machines are discussed. A detailed comparison of the four most relevant and recent methods identifies the differences. By means of measurement results of different machines, the differences between and the shortcomings of certain methods is confirmed. In that context, special attention is paid to the new, so-called ‘Eh-Y’ method. A concise overview of the most important points of attention for an increased efficiency of motor drives en the role of the induction motor (efficiency) in this context is completed with some examples. The difference between motor and generator mode is discussed and explained based on measurement results of machines of different size and efficiency class. Special attention is paid to the behaviour and performance of induction machines supplied by unbalanced voltages. More specifically it is investigated if and how the susceptibility to voltage asymmetry is influenced by material choice, in which the main focus lies on copper rotor technology. Therefore, the different standards for the description and quantification of voltage unbalance are studied first. The theoretical discussion is backed-up with experimental results of several machines.

  • Graphene is an extremely low density material, almost an atomic-scale chicken wire made of carbon atoms and their bonds. It has been the focus of much research because of its exceptional electrical, mechanical and optical properties. It holds great promise in renewable energies. Among the so far underutilized advantages Graphene offers are that it is fifty times stronger than steel, and it has five times the conductivity of copper, with only one quarter of the density.
  • Colin Bennett on 09 Nov 09
     
    Because of its light weight Graphene is the ideal substitute for copper for aerospace defense against emerging weapons technologies such as electromagnetic pulse as well as lightning strike protection for the aerospace market.

  • The researchers there have developed a system that is simpler to assemble and manufacture, and laid out their suggestion in a paper (pdf) presented at the 2008 European Wind Energy Conference. Till now; the blades of wind turbines have been connected to a generator via a gearbox. Their technology substituted a “C” shaped core generator (initially in a 20 kW prototype) to test to see if by changing the mechanical structure of the generator they could still maintain rigidity and structural integrity while cutting the weight by more than half. The design is simply a novel arrangement of the electromagnetically active components: the magnets, steel and copper inside the generator and the copper coils.

    They want to supply residential and business buildings with largely fiber optic connections because the old copper cabling will soon no longer suffice to access communication networks. The growing Internet data network plus new online and multimedia services require increasing amounts of bandwidth and better transmission technology.

    Back in October, we called Miasole, which makes copper indium gallium selenide (CIGS) solar cells, about a rumor that the company cut about 50 employees and planned to close its Shanghai operation. Today, VentureWire wrote that sources outside the company say Miasole has laid off 40 employees. Miasole did not comment on the story. Sources in the CIGS world however have been telling us that they had been receiving resumes from Miasole employees for the past several weeks. So even if people haven't been laid off, employees seem to be restless.
