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

Companies would spend more than $6-billion on submarine and terrestrial fibre optic cable infrastructure projects in Africa over the next two years, as countries scramble to boost international connectivity, market analysis firm BMI-TechKnowledge (BMI-T) said on Wednesday. In its latest research report, entitled 'Outlook for submarine and terrestrial fibre-optic cable developments in Africa', BMI-T said that the effective high-speed internet services required for critical business, government and consumer applications have remained either unavailable or very expensive in Africa. Governments' awareness of this situation, and the perceived commercial attractiveness of the opportunity to close this gap, has given rise to the current frenetic activity for construction of submarine fibre cables on the continent. Investment in Africa's ICT infrastructure has improved significantly over the past decade. However, marked deficiencies persist in the backbone networks across the continent. "Although countries on the African west and southern coasts have access to fibre connectivity through the SAT-3 undersea cable, an estimated 80% of Africa's international voice and data traffic is carried via satellite," said Chanakira.

"Engaging with government: finding new ways to communicate and collaborate - Strategies to counter regulatory uncertainty include working to build better government relationships, becoming more vocal in both industry association and through social media, measuring social impact, helping to set the policy agenda, and better leveraging mobile technologies."

Last week the Spanish government announced plans to cut subsidies for solar photovoltaic (PV) power by about 75%. Although the nation expects to surpass its 2010 goal for installed solar by four fold, the down side is that generous subsidies for the industry have resulted in a ballooning tariff deficit for the country, which has risen to 4.85 billion euros, upfrom 745 million last year. Reuters reported that lending to the Spanish photovoltaic plants has risen to $3.59 billion in the year to day, up from $230.9 million euros last year and $192.44 million in 2006. As a result, the Spanish government will as the energy regulator to cap subsidies for new PV solar capacity at 300 megawatts (MW) per year--200 MW for rooftop systems and 100 MW for ground-mounted systems, which have been the highest growth area. CSP has been slower than PV technology in its emergence on the renewable energy scene, but expectations for the technology, which focuses the heat of the sun to produce steam to drive electricity producing turbines. Projects underway in the U.S. and Spain are expected to produce electricity that is cost-equivalent to electricity produced from burning coal or natural gas.

A strike planned to start on Monday at Southern Copper's Peruvian mine Cuajone has been temporarily suspended pending mediation, officials from the company and union said. Southern, one of the world's largest copper producers, has been hit by strikes this year in Peru as workers demand a larger slice of the country's economic boom. Union leaders had planned to go on strike again because the company had threatened to fire about a dozen workers for participating in recent walkouts. But Roman More, head of the union at Cuajone, said the strike slated for Monday was called off as the company agreed to sit down with workers and the government for talks on Tuesday. Unions from the company's Ilo smelter and Toquepala mine were also expected to participate. "We are going to meet on Tuesday to see if we can reach an agreement about the firings. The meetings were requested by the government," More said. Alberto Giles, the company's human resources director, said the strike plans were scrapped. "In the case of Cuajone ... they suspended the strike plan," he said. "With regards to Ilo, the strike was supposed to start on Wednesday, but I don't think there will be a strike. I think the strike will also be canceled at Ilo." Cuajone, which produced some 148,939 tonnes of copper last year, is Southern's biggest mine in Peru, the world's No. 2 copper producer.

Mongolia's political parties are locked in post-election squabbling, but once the dust settles a new government could finally pass deals to tap the coal, copper and uranium that sit beneath its vast deserts and grasslands. But analysts say the deal that goes ahead would be less than ideal for either Mongolia or foreign investors, with the country better served by taxing its mineral wealth, rather than seeking direct government ownership in massive mines. The current law gives the state either a 34% stake or a controlling 51 percent stake in mining projects. An investment agreement with Ivanhoe Mines and Rio Tinto for the Oyu Tolgoi project, still under negotiation, would be the first such deal.

The current growth in the local and international engineering, civils and construction markets is expected to continue despite the current volatility experi- enced in world economic markets, reports the South African Association of Consulting Engineers (Saace). Saace CEO Graham Pirie says that even though the local infrastructure roll-out programme and the infrastructure investments from emerging markets such as China were initiated before the period of global market volatility, infrastructure builds cannot be halted as they are vital to the economic growth of countries. "Government's commitment of R500-bil-lion, in addition to the money invested in the 2010 FIFA World Cup stadiums, to be spent over three years, means that 2010 is a small component of a larger investment that government is encouraging," says Pirie. He comments that the infrastructure roll-out programme is necessary, given the 20-year infrastructure investment backlog that South Africa needs to resolve. Pirie says that events hosted in the country since 1994 have encouraged infrastructure reinvestment. "Prior to 1994, South Africa didn't host sporting or political events that would draw an influx of tourists into the country, so the need for infrastructure reinvestment was minimal. "From 1994, with the 1995 rugby World Cup looming, government got serious about resolving this. Certain sporting events, such as the 1995 rugby World Cup, the 2003 cricket World Cup and the 2010 soccer World Cup, focus the right amount of attention on infras- tructure reinvestment at the right time," says Pirie

A U.S. government official said dramatic improvements to lithium batteries are needed before they can efficiently power vehicles. Experts believe lithium-ion batteries are widely predicted to replace nickel metal-hydride batteries currently used in most hybrid vehicles like Toyota Co's popular Prius. The biggest challenges are extending the life of high-power lithium batteries and bringing down their relatively high cost, Tien Duong of the U.S. Department of Energy said on the sidelines of a lithium battery conference held at this government laboratory. "Life means 10 years, plus. For hybrids we know (their batteries) last 10 years plus. For the PHEV (plug-in electric vehicle), we don't know," Duong said. He did not specify what the costs should be. "One of the phenomenons that cuts short the life of the battery is power. You may have a lot of energy, but if you run out of power, that's no good," he said.

NEW YORK (MarketWatch) - Deal making and development in the wind arena continue even as the economy slows down, with the federal government moving ahead to grant leases for the U.S.'s first offshore wind projects in history and other state-based projects moving to the front burner. Comments on federal rules to govern a host of alternative energy projects proposed in federal waters off the coast of the U.S. drew about 225 responses by Monday's deadline, as the U.S. Mineral Management Service, or MMS, moves ahead with plans to lease the outer continental shelf to several companies.

Whatever specific actions governments take, executives indicate that support for innovation should be the overall focus of governments' actions, rather than help for existing industries or companies (Exhibit 6).

That "evidence" relates to an article published by The Australian on May 28 which stated, "In Japan, the world's biggest importer of rare-earth metals, more than 10,000 tonnes per year about a fifth of the country's total annual consumption are thought to enter the country through a thriving black import network without which Japan would already be in a severe supply crisis, a senior government official said." We believe a black market exists, in this particular case, because of several actions taken by the Chinese government (by the way, the RE (rare earths) black market in Japan receives its supply from China). The biggest reason a black market exists however, relates to mining quotas and export restrictions. In addition, China has taken an active international M&A stance to make strategic investments.

"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"

"1. Chinese smelters are jointly calling on the government to scrap the 15% export tax on aluminium ingots, as they hope to benefit from a global market deficit. Yet many market participants cast doubts on the proposal as it is against Beijing's industrial policy on the light metal. 2. Beijing has cancelled approval requirement for aluminium smelting projects, but it continues to keep tight control over the sector, ordering local governments not to register new aluminium smelting..."
