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

Car sales have dropped by 67.1% in Beijing after city authorities imposed a car purchase limit policy at the start of 2011. According to the China Association of Automobile Manufacturers (CAAM), sales were down from 283,000 vehicles in Q1 2010 to 93,000 in the same period this year, with new cars accounting for 66% of sales. Automotive production is closely linked to copper demand, with the industry having an estimated 6.9% market share of world copper consumption.

With a view to cutting operating costs, Mitsui Mining & Smelting Co. and Sumitomo Metal Mining Co. are planning to combine their copper and alloy businesses. The new joint venture will consist of equal shares of the two companies and will be Japan's biggest brass strip maker. Major end-use applications include terminals and connectors for cars and electronic components. According to the plan, the joint venture will cease some sales units and purchase raw materials on a joint basis. It is anticipated that annual cost savings will amount to 1B yen (US$10M).

Because of slowing housing construction and the consequent decline in demand for gas appliances and water taps, the demand for brass bars in Japan is falling. Demand is also being affected by the decrease in car industry activity. As a result, brass bar makers in Eastern Japan are planning to reduce production output for the fourth quarter by 20-25% on a year-to-year basis. August production in Japan was ''as low as 16,362 tonnes'', according to the Japan Copper & Brass Association. Monthly order receipt volume for the last three months of 2008 is expected to average just 15,000 tonnes.

Kitz Metal Works, a brass bar maker and subsidiary of the Kitz group, announced plans to add a continuous casting line at its Chino plant in Japan. The US$2.6M development will add a further 18,000t-19,200t to the company's annual billet production capacity. Construction work is set to begin this month and the plant is expected to be commissioned by the end of the year. The company expects that the lower production cost of the new casting line will allow for the investment cost to be recovered within five years.

Hitachi Cable Ltd. announced that it will cease production at its Tsuchiura plant by March 2012, effectively ending its domestic copper tube business. The facility produces copper tubes for air conditioners and in FY2010 it contributed to a sales volume of 20,000t; a sales value of ¥17.76B or 4.2% of the company's total revenue. The withdrawal from the business is attributed to difficulty maintaining profitability after air conditioning manufacturers shifted operations to foreign markets. Hitachi will keep a 50-50 JV with Furukawa Electric in Shanghai and its 36% share of a Thailand based copper tube manufacturer.

The process from design to launch is now much shorter

Storyline of the disruption that might happen over the coming decade if TaaS (Transport as a Service) becomes a reality. Implications for the oil & gas industry (stranded assets), cities (lots of free space), construction (a boom), grids (no peakers, no market for ancillary services), and of course for the automotive sector.
