This technology seems to me to be much more beneficial on a local scale, what if every home had its own battery, then home power generation becomes economically more viable for everyone. If you could show that a system like this could pay for itself in say 5 years then every home would want one. Plus for this to be implemented on a large scale requires massive investment that could be decades away. Share the technology and lets get it in homes by next year. Great ted talk. Jon Senior 0 Reply 1 hour ago: I agree 100%. Localised energy production would also make energy consumers more conscious of their consumption and encourage efforts to reduce it. We can invent and invent all we want, but the fast solution to allowing renewable energies to take centre stage is to reduce the base energy draw. With lower baseline consumption, smaller "always on" generators are required to keep the grid operational. Town and house-l

June 2008\nNA Copper Mail

Norddeutsche Affinerie AG (NA) said it is expecting at least EUR40 million of synergies each year from the takeover of Cumerio which was completed in March this year. The company said that it will benefit from the transfer of best practice between the two companies while cost savings mainly come from logistics and process optimization. NA also plans to increase production at its Cumerio smelters. The company expects further acquisition opportunities in Europe and in other parts of the world, including Asia. NA plans to expand its operations in southeastern Europe and the Black Sea region to capitalize on its strong economic growth before looking for growth opportunities outside Europe. In Bulgaria, the company currently expands copper cathode production capacity of its Pirdop smelter to 180,000 tonnes per year.

Norddeutsche Affinerie is to invest €62.5M to increase by 60% its copper scrap recycling capacity in Lünen, Germany by 2011. The investment will double the firm's capacity to process complex copper-bearing scrap such as shreddings, powders and electrical scrap to 140,000t/y, bringing total scrap recycling capacity up to 350,000t/y from 220,000t/y currently. The scrap will be processed into copper cathode. The investment will see the installation of a second smelting furnace, and a waste gas purification plant in Lünen. Norddeutsche's current secondary smelter in Lünen uses a range of scrap, whilst its Hamburg plant uses copper concentrate and a small percentage of high-grade scrap. Electronic scrap availability has increased in Europe as end-of-life regulations have been introduced for its disposal.

The Shanghai Futures Exchange announced that it will begin delivery of copper and aluminium futures contracts at warehouses at Yangshan port. Settlement will be in RMB without tax and that will reflect international prices. The Shanghai Yangshan port bonded zone has been approved by the State Council and was officially put in operation on 10th December. The area is also home to a number of trading houses and logistics companies.

Another one in a series of studies on this topic. This one predicts an 87,000% increase in the demand for battery materials which is not very helpful. Exponential extrapolation from a small basis over a long time horizon can basically come up with any growth figure. The logistic growth curve is a much better and proven model for technology transitions.

"Demand for cobalt, copper, lithium, cadmium, and rare earth elements needed for solar photovoltaics, batteries, electric vehicle motors, wind turbines, fuel cells, and nuclear reactors is set to explode in the coming years as countries around the world invest heavily in greening their economies".
