Inherently fault current limiting ( IFCL ) superconductor cable - 0 views

The technology is capable of carrying 10 times as much power as copper wires of the same size, while also being able to automatically adapt to power surges and disruptions from lightning strikes, heat waves, and traffic accidents, even sabotage. A single superconductor cable can replace 12 copper cable bundles, freeing up more space underground for other utility needs like water, natural gas, or phone service.

Solar industry fights utility's big solar project - 1 views
-
When Southern California Edison unveiled plans to install 250 megawatts' worth of solar panels on warehouse roofs back in March, it was hailed as a ground-breaking move. In one fell swoop, the giant utility would cut the cost of photovoltaic power, expand the solar market and kick-start efforts to transform untold acres of sun-baked commercial roof space into mini-power plants. There's just one problem: the solar industry is fighting the billion-dollar plan. In briefs filed with the California Public Utilities Commission, solar companies, industry trade groups and consumer advocates argue that allowing a utility to own and operate such massive green megawattage will crowd out competitors who can't hope to compete with a project financed by Edison's ratepayers. (In California, shareholders of investor-owned utilities are guaranteed a rate of return for approved projects, while utility customers bear a portion of the costs in the form of higher rates.) The five-year plan "would establish SCE as the monopoly developer of commercial-scale distributed solar in its service territory," wrote Arno Harris, CEO of Recurrent Energy, a San Francisco company that sells solar electricity to commercial customers. "This would irreparably impair the development of a competitive solar industry."

Boeing Dreamliner 787, an aircraft that was considered as a preferred choice for civil aviation almost a week back. But, the recent fire in this Dreamliner series has sparked many questions on the process of assembling and constructing an aircraft through advanced technology. Nearly 50 Boeing 787 Dreamliner aircraft are in operation across the World, the recent fire has raised lot of speculation and doubts on the performance of lithium-ion batteries in automotive and industrial applications. This incident has opened a new page in the lithium-ion battery space, to rethink about the safety of this battery when used in higher capacities of KW and MW scale.

Skylon Testing Success for Fine Tubes and Reaction Engines - 0 views
-
Fine Tubes used Inconel, a nickel alloy that has excellent heat resistance. Because of the amount of tubing required, it had to be as lightweight as possible. Inconel is a difficult material to shape and the thinness required meant it was easily damaged, so to fulfil Reaction Engines' requirements Fine Tubes installed completely new equipment for the tube cleaning process at its tube mill.
Middle East infrastructure - LS Cable & System wins two contracts for 157km EHV - 0 views
-
Of the two projects, the former was initiated when Qatar realized that their current power grid could not effectively keep up with the ever increasing power demand generated by the continual economic development and urbanization happening within their borders. For this project, LS Cable & System will supply a total of 157km of 220kV level extra high-voltage cables and joint kits to the Doha area by July 2013. The latter is to supply Hyundai E&C who won a contract in 2010 to renovate the 2006 Doha Asian Games athletes’ village and office buildings into a four-building high-tech medical center. For this project, LS Cable & System will deliver bus ducts that are popularly used in buildings and factories to transmit large amounts of electricity through a small space. Analysts point out that Middle East countries are currently promoting petrochemical, refinery and power plant projects as well as large-scale public works and construction projects to boost their economies with extra spending.
Leoni opens new wiring systems plant in Jining, China - 0 views
-
Group-wide and including the joint venture plants, Leoni now has 11 facilities in China with a total of about 6,000 employees. In terms of consolidated sales, which in the current financial year will amount to about 350 million euros, China meanwhile represents the third largest market after Germany and France. The Company has been operating for 18 years with its own facilities in China. To be able to satisfy the heavy demand from the automotive industry for cable harnesses and wiring systems, and especially to be able to supply for new vehicle models, Leoni is also setting up new production lines and expanding existing plants in other regions. The Wiring Systems Division alone currently has 12 capital investment projects, involving for instance plans for two new facilities in Egypt as well as one each in the Ukraine and Russia. Furthermore, there will be additional production halls in Brazil, Mexico, Morocco, Tunisia and Serbia among other places. After the expansion is completed, the Wiring Systems Division’s network will comprise more than 30 production facilities with a total of more than 550,000 square metres of factory floor space.
It's time to start mining the moon? - 0 views
-
What are the milestones after you land?Once we prove we can land safely we'll show we can hover over the lunar surface. We may leave a small commemorative payload on the moon and then lift off to lunar orbit. Bringing anything we later mine back from the moon will have three separate, technically challenging elements: getting mined resources into lunar orbit, from there to Earth orbit, and then to Earth's surface. The great thing here is that we don't have to invent anything new to do all this.
The Forgotten Cold War Plan That Put a Ring of Copper Around the Earth - 0 views
-
The same year that Martin Luther King, Jr. marched on Washington and Beatlemania was born, the United States launched half a billion whisker-thin copper wires into orbit in an attempt to install a ring around the Earth. It was called Project West Ford, and it’s a perfect, if odd, example of the Cold War paranoia and military mentality at work in America’s early space program.

Copper ranks second to silver as an electrical conductor. The copper cladding of LEONI Histral® H16 ensures a good electrical conductivity whenever mechanical properties do not play a primary role.
-
High-frequency (HF) technology In HF technology the so-called „skin effect“ ensures that the current flow is restricted to a very thin layer situated on the surface of the conductor and that the overall resistance in the conductor is reduced. LEONI Histral® H16 has copper, which features good electrical, in the cladding only. The additional galvanic plating of the surface causes the skin effect to be optimized. Aeronautics and automotive technology Weight is of major importance for the construction of airplanes and automobiles. LEONI Histral® H16 is particularly suited for larger cross-sections here that can be employed for the transmission of power, where there is a significant weight reduction potential. Shielding braids LEONI Histral® H16 features a resistivity lending itself well to shielding braids because high coverage can be achieved at a comparatively low weight. The fact that aluminum suffers from the drawback of having a poor contact resistance is largely offset by the copper cladding. Heating applications The combination of a relatively good resistance value with a rather low mechanical resilience suggest that LEONI Histral® H16 may well be used in all kinds of heating applications that are not exposed to a permanently varying level of stress.
EU EUR 1 Billion Graphene Flagship - 0 views

Graphene Flagship – the EU's biggest research initiative ever, and, according to the European Commission, 'history's greatest distinction for excellent research'– is closely linked to the Graphene Centre at Chalmers. With a budget of EUR one billion, the Graphene Flagship is tasked with taking graphene from the realm of academic laboratories into European society in the space of ten years – thus generating economic growth, new jobs and new opportunities for Europeans as both investors and employees. There are already 126 research groups from universities, research institutes and companies on-board the flagship.
The BMW i3 begins production - 0 views
-
The stator, which forms the inner core of the motor, consists of around two kilometres of wound copper wire. Unlike other electric motors in the same power class, the motor of the BMW i3 is very small and compact due to the specially configured winding of the copper wiring. This results in further weight and space savings. Before the rotor is fitted in the interior housing, it receives a thin coating of resin.
