the CAIR decision could have done permanent damage to any cap-and-trade approach \nto pollution control.

The Trai statement said, the country added 8.81 million telephone connections (both wire and wireless) during June 2008 as compared to 8.46 million it added during May 2008. In the wireless segment, which includes GSM, CDMA and WLL, there was an addition of 8.94 million as against 8.62 million during May 2008.

So when Thomas S. Monaghan purchased 270 tons of copper sheet metal to roof his dream project -- creating a Catholic university in southwest Florida -- he had to do some serious soul-searching when the value of the copper more than doubled within two years.

Growing a mixed "lawn" of two kinds of nanowires can make a new kind of light-sensing array that could be made in metre-scale sheets. The researchers behind the prototype say such cheap, high-quality image sensors would allow uses not conceivable using today's more expensive technology. Current sensors, such as those found in digital cameras, are made like any other silicon chip - they are carved out from a block of material. The new nanowire sensors are instead built from the bottom up, using chemically-grown nano-sized components. A research team led by Ali Javey, at the University of California, Berkeley, developed the process. They start by growing an unruly "lawn" of nanowires on a surface. The crop is then printed onto another surface, a step that simultaneously tidies them up. "At the first stage, the nanowires are more-or-less standing up, like a bad hair day. But during the printing process, they effectively get combed," says Javey. The nanowires, which are a few tenths of a millimetre long and a few tens of nanometres wide, can be printed onto anything from silicon to plastic or paper. Whatever the surface, it must be prepared with a pattern that guides the nanowires to predetermined locations. To make the functioning sensor, two different "crops" of nanotubes are printed onto the same surface. Cadmium selenide nanowires produce electric charge when hit by light, while those made from silicon-coated germanium act as transistors to amplify that charge.

\n\nNEW YORK - ITT Corp. handed in a 3% higher second-quarter profit Friday, with a weak dollar and strong overseas demand for its pump, valves and electronics systems shielding the company's bottom line from the economic downturn at home. During the quarter, ITT won a major contract to provide filtered seawater to Esperanza, a large new copper-gold mining project in Chile's Atacama Desert.

Pennsylvania Gov. Edward Rendell has approved a bill that establishes a $500 million fund to support alternative energy projects. Special Session House Bill 1 authorizes the Commonwealth Financing Authority to borrow $500 million, most of which will be split into six funding sources relating to energy efficiency and renewable energy: $80 million in grants and loans for solar energy projects; $100 million in grants, loans, and rebates for up to 35 percent of the cost of solar energy projects at residences and small businesses; $165 million in grants and loans for alternative energy projects, excluding solar energy, at businesses and local government facilities; $25 million for wind and geothermal energy projects; $40 million to help start-up businesses involved in energy efficiency technologies; and $25 million in grants and loans to improve the energy efficiency of new and existing homes and small business buildings.

TOKYO - Nippon Mining & Metals Cob said it has developed a new technology that enables efficient recovery of copper and gold from low-grade copper concentrates. Nippon Mining will invest some 2.8 billion yen to build a pilot plant in Australia, in cooperation with major local mine operator Newcrest Mining Ltd.

A new approach to storing electrical energy can store more energy than gasoline in the same volume, and could help extend the range of electric vehicles. But some experts say other approaches are more practical. The biggest technological hurdle facing electric vehicles is their range. Even the best rechargeable batteries cannot match the density of energy stored in a fuel tank. Combining electric power with a combustion engine to make a hybrid electric vehicle sidesteps that problem. But a new take on electrical power storage that is part battery, part chemical fuel cell could ditch gasoline for good.The new design stores energy more densely than petrol, and was conceived by Stuart Licht of the University of Massachusetts, Boston, and colleagues. Batteries produce electricity from a closed chemical system that is eventually exhausted. Fuel cells use a constant supply of fuel, so they are continually topped up. Licht's cell has features of each. Its negative electrode, or anode, is made from vanadium boride, which serves double-duty as a fuel too. But unlike the flowing fuel of a fuel cell, the material is held internally, like the anode material of a battery. The vanadium boride reacts with a constant stream of oxygen, as in a fuel cell, provided by the positive electrode, or cathode. This brings in a supply of air from outside.

Dwarfed by any of the north African nations, it represents an area slightly smaller than Wales but scientists claimed yesterday it could one day generate enough solar energy to supply all of Europe with clean electricity. Speaking at the Euroscience Open Forum in Barcelona, Arnulf Jaeger-Walden of the European commission's Institute for Energy, said it would require the capture of just 0.3% The scientists are calling for the creation of a series of huge solar farms - producing electricity either through photovoltaic cells, or by concentrating the sun's heat to boil water and drive turbines - as part of a plan to share Europe's renewable energy resources across the continent. A new supergrid, transmitting electricity along high voltage direct current cables would allow countries such as the UK and Denmark ultimately to export wind energy at times of surplus supply, as well as import from other green sources such as geothermal power in Iceland. Energy losses on DC lines are far lower than on the traditional AC ones, which make transmission of energy over long distances uneconomic. The grid proposal, which has won political support from both Nicholas Sarkozy and Gordon Brown, answers the perennial criticism that renewable power will never be economic because the weather is not sufficiently predictable. Its supporters argue that even if the wind is not blowing hard enough in the North Sea, it will be blowing somewhere else in Europe, or the sun will be shining on a solar farm somewhere.

The redeveloped World Trade Center will be "one of the largest fuel cell installations in the world" according to the New York Power Authority (NYPA). Under the US$10.6 million agreement between NYPA and fuel cell developer and provider UTC Power, fuel cells with a total capacity of 4.8MW will provide an on-site supplement to the renewable and other clean energy that will power the rebuilt centre. The first fuel cells will be delivered to the Freedom Tower in January 2009, and will be owned and operated by the Port Authority, which also owns the building. The fuel cells for the other three towers will be owned and operated by World Trade Center Properties, LLC. "Fuel cells are one of the environmentally beneficial technologies that the Power Authority is investing in under Governor Paterson's leadership to combat greenhouse gas emissions and diversify the state's energy mix. To date, we've installed 15 fuel cells in New York City and other locations, and expect to add to this total in support of the Governor's ambitious goals for significant increases in the state's renewable power," says Roger B Kelley, NYPA President and Chief Executive Officer.

Newmont Mining Corp. posted a sharply higher second-quarter profit Thursday, with record-high gold prices and production gains pumping revenue past most analysts' expectations. Newmont (NEM:Newmont Mining Corporation News, chart, profile, more Last: 49.02+0.25+0.51% 2:30pm 07/25/2008 Delayed quote dataAdd to portfolio Analyst Create alertInsider Discuss Financials Sponsored by: NEM 49.02, +0.25, +0.5%) shares rose $1.82, or 3.9%, to close at $48.77. The stock is up 12% over the past 12 months. Newmont reported net income for the three months ended June 30 swung to $277 million, or 61 cents a share, from a year-ago loss of $2.06 billion, or $4.57 a share. The year-ago numbers were heavily skewed by a $1.67 billion write-down tied to the company's exit from merchant banking and a $460 million charge for settling price-capped forwards contracts. Adjusted earnings from ongoing operations more than doubled to $230 million, or 51 cents a share, from $103 million, or 23 cents, a year earlier. Gold sales during the quarter totaled 1.27 million equity ounces, fetching on average $900 an ounce, as the precious metal rode a huge spike in commodity prices. Gold prices were averaging about $600 an ounce a year ago. Costs per ounce rose, however, to $440 an ounce from $417 a year ago. Copper sales accounted for $183 million during the quarter, down from $340 million a year earlier. Newmont stood by its earlier 2008 production forecast of 5.1 million to 5.4 million ounces of gold, with production cost expected to range from $425 to $450 per ounce.

Earlier this week Google.org, the philanthropic arm of web technology company Google (Nasdaq: GOOG), announced its first two investments under its RechargeIT initiative, which aims to accelerate the adoption of plug-in electric vehicles. Google.org's official blog stated that RechargeIT, which released a request for proposals last Septmber, invested a combined $2.75 million into ActaCell, an Austin, Texas-based battery developer, and Aptera Motors, a Carlsbad, California-based electric car maker. In the blog posting Karl Sun, an investments principal Google.org, said, "Both of these innovative companies and their capable teams are working to develop technology that is crucial to helping us realize the RechargeIT vision: millions of plug-in vehicles on the road." The ActaCell investment was part of a larger Series A funding round that raised $5.8 million for the company, which began at the University of Texas at Austin. Funders included DFJ Mercury, Good Energies and Applied Ventures, the venture capital arm of Applied Materials (Nasdaq: AMAT).

Two Japanese companies are working together to develop carbon fiber materials for use in cars, according to a Reuters report. Toray Industries (3402.T) and Mitsubishi Rayon (3404.T) hope to mass produce the lightweight material by 2010 in an effot to make vehicles 40% lighter and up to 30% more fuel efficient. They also intend to develop technology to recycle carbon fiberin order to bring costs down. For years, proponents of carbon fiber materials have supported its widespread use in vehicles, but the cost of the highly engineered materials was prohibitive. Now with gasoline and steel prices on the rise, carbon fiber is becoming more economically feasible. The Nikkei business daily reported that Nissan Motor Co. and Honda Motor Co. were participating in the partnership, along with Toyobo Takagi Seiko Corp and researchers from the University of Tokyo. However, both Nissan and Honda denied that they were participating in the project. A spokeswomam for Japan's New Energy and Industrial Technology Development Organization said teh government is also researching the further use of aluminum and other light-weight metals to replace steel.

General Motors (GM) announced that it is adding the world's largest rooftop solar photovoltaic power installation to its car assembly plant located in Figueruelas, Zaragoza, Spain. When the project is completed in fall 2008, the Zaragoza solar installation will cover about 2 million square feet of roof at the plant and include about 85,000 solar panels. When fully operational, the Zaragoza solar installation will generate about 12 megawatts of power at its highest output. The installation will generate about 15.1 million kWh of power annually, which is equivalent to the demand of 4,575 households with an average annual consumption of 3,300 kWh in Spain. "The Zaragoza project demonstrates proof that GM is actively accelerating our efforts to be part of the solution to the environmental issues and challenges facing our world," said Gary Cowger, GM group vice president of global manufacturing and labor relations. "We are proud to be a global leader in the usage of renewable energy."

Investors piled out of Russian stocks Friday after the abrupt departure from the country of a foreign oil boss and the prime minister's unexpected severe criticism of a large steel firm. MICEX, the exchange where the bulk of trading in Russian stocks takes place, plunged by 4.8 percent as of 12:20 p.m. Russian time, while the RTS, a top stock index, lost 4.4 percent to drop beneath the critical 2000-point barrier for the first time since March. After Prime Minister Vladimir Putin's scathing attack on Mechel late Thursday, heavy trading in New York sent the steel and coal maker's stock down by nearly 40 percent, losses mirrored Friday morning in Russian trading. The premier criticized the company, which is the largest supplier of coal for steelmakers in Russia, for charging much higher prices for raw materials domestically than it does for its exports, and called for an antitrust investigation into its activities.

Copper prices tumbled to a five-week low Thursday on expectations that falling demand from China and a slowdown in the U.S. housing market will lead to a surplus of the metal. Other commodities traded mixed, with crude oil rebounding slightly and gold, silver and soybeans falling. Corn and wheat futures rose. China, the world's biggest buyer of copper, has been importing less of the metal since the completion of most major construction projects heading into the Beijing summer Olympics. Copper imports in June fell 20 percent compared to May, China's custom's agency said this month. As a result, stockpiles of the metal have swelled in Shanghai and London, helping drive down prices.
