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

The State Administration of Taxation in China announced that it will increase its export tax rebates on copper foil, plate and tube from 1st April. The policy was announced on 27th March and it aims to boost Chinese exports. Copper plate's export tax rebate will rise from 5% to 9%, copper foil's from 5% to 13%, and copper tube's from 9% to 13%. It is expected that the measure will support the copper semis market.

Paranapanema announced that it approved a capacity expansion and technology modernisation plan, supported by a positive macroeconomic outlook and favourable price trends for its products. The market will be boosted by Brazil's anticipated economic growth, and in particular by infrastructure, civil construction, electricity and green power projects. In addition, the 2014 World Cup and 2016 Olympic Games will provide further support. Paranapanema will increase its refined copper capacity at its Dias D'Avila unit from 230,000tpy to 280,000tpy in H1 2012. The company will also install a precious metal refining plant at the same unit, scheduled to be operational in H2 2012. Paranapanema's copper semis division, Eluma, will expand its cold rolling capacity from 28,000tpy to 55,000tpy. Furthermore, hot rolled products capacity will rise from 60,000tpy to 200,000tpy whilst tube capacity from 18,000tpy to 36,000tpy. Investment of the entire plan for 2011-13 will amount to 630 million reais (US$377 million).

On 6th August, Xstrata reported H1 profits were down 6.7% versus the same period in 2007. Revenues were 13% higher at $16.092 billion, after record first-half production in coking and semi-soft coal, ferrochrome, refined nickel, platinum, zinc concentrate and lead concentrate. The company expects second-half production to be even stronger, reflected in their decision to raise the interim dividend by 13% to 18c. per share. Xstrata remains bullish over demand prospects in China, with ongoing infrastructure development and urbanisation underpinning growth, adding "the Group is well positioned to enjoy margin expansion and improved profitability from the second half of 2008 and into 2009".

The Y. S. Sun Green Building Research Center, which costs TWD87,000 ($296,1) per 36 square feet, adopts 13 different green building design methods, including five natural ventilation energy-saving methods, two equipment reduction methods, and five equipment energy-saving technologies and renewable energy technologies.

Toyota Motor Corporation announced on 5th November a sharp increase in H1 2012 revenues of 36.1% y-o-y compared with the same period in 2011. The increase was largely due to base effects associated with last year's Japanese earthquake and tsunami. As part of the announcement, Toyota revised up their annual profit forecasts to JPY1.05T from JPY1.0T (US$13.29B from US$12.66B). However, Toyota revised down overall expected 2012/13 car sales by 50,000 units. This was driven by downward revisions to Asian and European sales forecasts, 50,000 and 40,000 units, to 1.73M and 790,000 units respectively. North America was a bright spot for Toyota, with expectations for full year North American automobile sales revised up by 20,000 units to 2.4M vehicles.

"SHANGHAI, Aug. 11 (SMM) - There is huge market potential to replace copper with aluminum in China's cable industry, cableabc.com reported. Market value of China's aluminum alloy cable approached 13 million yuan ($2.1 million) in 2014. However, China's rate of substituting aluminum alloy for copper in cable is just 3%-5% at present, well below 55% in Japan. Currently, the rate of using aluminum alloy and Al-Mg-Si alloy to replace copper cable has reached 70%-75% in the US, cableabc.com added, quoting data from Research and Markets. "

Rohm and Haas Company has reported second quarter 2008 sales of $2,567 million, a 17% increase over the same period in 2007, with Electronic Materials and the chemical businesses outside North America delivering strong growth. The Electronic Materials Group comprises two reportable segments which provide materials for use in applications such as telecommunications, consumer electronics and household appliances. Sales for the Electronic Materials Group were $536 million in the second quarter of 2008, up 34% over the same period in 2007, reflecting the impact of acquisitions in Display Technologies as well as solid organic growth of Electronic Technologies. The Electronic Technologies segment is comprised of the company's Semiconductor Technologies, Circuit Board Technologies and Packaging and Finishing Technologies business units. Sales for the segment of $460 million were up 16% versus the second quarter of 2007, driven by strong growth in Asia for all business units. Sales in the second quarter excluding precious metals pass-through sales were up 15%. Semiconductor Technologies sales grew 13%, reflecting strong demand and favorable currencies, particularly in the Asia Pacific Region. Circuit Board Technologies sales increased 20% as compared to the same period last year, with solid growth in the Asia Pacific Region more than offsetting declines in North America. Packaging and Finishing Technologies sales rose 20% versus last year, primarily driven by strong growth in precious metal sales and in process sales. Adjusted pre-tax earnings for this segment of $107 million were up 11% from the second quarter of 2007, reflecting increased demand and favorable currencies, partially offset by higher metal costs and increased costs related to expansion efforts, including the new Asia Technical Center in Taiwan.\n\n\n

Growth in Asia is illustrated from this reporting at multiple levels of business - Opportunities are available for copper in a multitude of applications.

The country will shut down small coal-fired power generators producing 13 gigawatts this year and require at least 80 percent of buildings under construction to meet energy-saving standards for the construction process by the end of 2008, the report said.

China's imports of unwrought copper and semi-copper products were down almost 13% month on month in June and by 18% year on year. This downturn in imports is said to have been expected, as June is traditionally a slower month for copper consumption. It does not therefore necessarily mean a downturn in Chinese demand especially as China has been importing increasing amounts of copper concentrates and scrap over the past few months. Over 1.3 million tonnes of unwrought copper and semi-copper products were imported to China in the first six months of 2008, a year on year decrease of 12%. It is believed that stocks have built up in warehouses following too many imports in 2007. Chinese copper imports are however expected to recover towards the end of July and August and will be assisted also by the running down of the built up stocks in the warehouses.

Jan du Plessis, Rio Tinto's new chairman, said the completion of Chinalco's proposed $19.5bn (£13.4bn) capital investment in the Anglo-Australian mining group would be his priority as he took over from outgoing chairman Paul Skinner.

Dongguan Huaxin Wire & Cable Co. Ltd. produced 4,433 tonnes of 8mm copper wirerod in April, down by 11.2% m-o-m. In the four months to April, the company produced 15.2kt of copper wirerod whilst it sold 13.9kt. About 78% of production in March and April was exported. Dongguan Huaxin's annual capacity of copper wirerod amounts to 72kt per annum.

ICSG 1 Feb 09 - Based on existing facilities and announced project developments, annual mine production capacity in the period 2009-2013 is expected to grow at an average rate of around 4.3% per year (%/yr) to reach 23.1 Mt in 2013, an increase of around 3.6 Mt (19%) from that in 2009. Of the total increase, copper in concentrate capacity is expected to increase by 2.7Mt (4.3%/yr) to reach 17.9 Mt and solvent extraction-electrowinning (SX-EW) production by 820,000t (4.4%/yr) to reach 5.2 Mt. Most of the new mine projects and expansions are located in Brazil, Chile, Congo, Mongolia, Peru, the United States and Zambia, which together account for around 2.6 Mt (73%) of the projected mine capacity increase during this period. Annual smelter capacity is projected to grow by an average of 2.6%/yr to reach 20.2 Mt in 2013, an increase of 2 Mt (11%) from that in 2009. Asia will be the leading contributor to growth (1.8 Mt), with expansions and new projects expected mostly in China, but also in India, Indonesia and Iran. Africa is the second leading contributor owing to developments in Zambia. North American smelting capacity will fall by 12% (250kt) due to closures of plants in Canada. The ICSG tabulations indicate that world refinery capacity will reach 26.6 Mt in 2013, an increase of 3.2 Mt (13%) from that in 2009. About 2.3 Mt of the expansion is expected to come from electrolytic refineries and 820,000t from electrowinning capacity. Electrolytic refinery capacity growth is projected to average 3.1%/yr, exceeding the projected growth in smelter capacity, and electrowinning capacity growth (at the refinery level) is expected to average 4.3%/yr. About one half (1.5 Mt) of the world refinery capacity increase during this period is expected to come from electrolytic refineries in China; about 25% (830,000 t) from electrolytic capacity increases in India, Indonesia and Iran; and about 20% (600,000 t) from electrowinning capacity increases in Congo, Peru and Zambia.

"The Chilean government has set its sights on significantly increasing its geothermal energy capacity. The Ministry of Energy recently announced a new contract for the development of 20 areas by 2012. 70 bids from 13 domestic and foreign firms were submitted for the rights to exploit the newly released regions of Rarapacos and Los Ricos. Earlier in the year, Energy Minister Ricardo Raineri announced more than 170 concessions for geothermal energy by 2012. He further specified that these concessions would be supported by US$200 million in funding from the government. The country is striving to increase its geothermal capacity to 1,000 megawatts in order to meet an ever-growing energy demand in a sustainable manner"
