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

"There's nothing going on. People have stopped buying and it doesn't look any better for the first part of next year either," said a physical trader. "People don't want to carry too much stock over the year-end but they don't have a lot of choice because of the turndown in demand. If people have got metal the best thing they can do is dump it on warrant and get paid by the warehouses," he said.

SINGAPORE, Sept 8 (Reuters) - Shanghai copper fell around 2 percent on Monday but it lagged behind a 4.5 percent slide in London prices after big jumps in inventories on Friday. But prices in London bounced on Monday, lifted by gains in other other commodity markets as the dollar lost ground against the euro after the U.S. government on Sunday seized control of mortgage finance companies Fannie Mae (nyse: FNM - news - people ) and Freddie Mac (nyse: FRE - news - people ), which own or guarantee half of all U.S. mortgages. LME copper rose $75 or 1.1 percent, to $6,975 at 0232 GMT, while Shanghai November copper dropped 1,030 yuan to 55,630 yuan ($8,130) and earlier touched a nine-month low.

And it still has a long way to go. Today, barely one in five people around the world has access to the internet. Yet around three-quarters of the world's population lives within reach of a mobile network. In the decade ahead, many people, especially in developing countries, will have their first contact with the internet via a mobile phone.

As China's economic lifeline, the iron and steel industry used to be a black smoke maker and blue-sky killer in the eyes of many people. In 2007, SO2 emissions by China's large and medium-sized steel and iron enterprises were estimated at 756,368 tons, down 0.51 percent year-on-year. And the discharge of industrial coal ash was 382,275 tons with a 2.79 percent decline. Otherwise, soot discharges increased 3.02 percent, totaling 156,648 tons. The Long March of environmental protection and energy efficiency for China's steel and iron enterprises is still challenging, though many in the iron and steel industry have launched a green revolution in order to improve their old image. Wuhan Iron and Steel (Group) Corp (WISCO) is one such environmental protection warrior. As China's thrid largest steel and iron manufacturer, WISCO used to be a major polluter in Wuhan, capital of Hubei province. Many residents complained and criticized the firm, joking that sparrows would turn black after flying over WISCO's mills.

A cable factory located in Lyudinovo, Russia, has laid off 40 people and cut the wages of the remaining personnel by 15%. The decision of the cable manufacturer, which had recently started up a new production line, is attributed to the global financial crisis. Plunging copper prices are a major threat to Russia's economy due to the high dependence of the country on commodity exports.

Others: #1: The majority of people who drive a plug-in vehicle won't own it. #2: "Automakers will get pushback from EV owners regarding the length of time it takes to fully charge a vehicle." #3: Many EV charging stations will spend the majority of their time idle. #4: 'Range anxiety' #5: "The best-selling EVs won't have four wheels

"The report focuses on automotive HVAC and Cabin comfort systems, which have cemented their place in a vehicle with the growing demand for luxuries. The automotive HVAC systems which were first introduced in 1930s are standard equipment in almost every vehicle in the developed markets such as U.S. and Europe. The key drivers behind the growth of this market are the rising amount of time spent by people in their vehicles and the growing popularity of private vehicles over public transport. The Asia-Pacific region is expected to be the largest segment in automotive HVAC market owing to the large vehicle production levels in countries such China, India, and Japan."

90,000 people now work there; arriving via car, Dockland Light Railway, on the Jubilee Line, or even by boat; which although an unusual way to commute is perhaps not so surprising as Canary Wharf is situated on the Isle of Dogs and surrounded by water on three sides.

\nCadiz, Spain - While significant challenges remain and large-scale applications appear relatively far out on the horizon, smaller scale applications, such as organic light emitting diodes (OLEDs), are already being built into a variety of electronic products. Industry pioneers, such as G24i, have begun manufacturing their first generation of products, which in G24i's case includes a DSC-powered mobile phone charger and an award-winning "Lighting Africa" portable lamp that marries cutting-edge LED and dye-sensitized thin-film PV technologies. \n\nLooking to bring off-grid electrical power options to people in Kenya, Nigeria, Rwanda, South Africa and a still growing range of African countries, G24i in May was awarded the World Bank Group's 2008 "Lighting Africa Development Marketplace" prize for its solar-powered LED light, which uses the company's proprietary dye-sensitized thin-film solar cells in concert with light emitting diodes (LED) produced by Dutch lighting manufacturer Lemnis. \n\nG24i dye-sensitized thin-film solar cells are proving themselves rugged enough to endure some of the harshest conditions on the planet. Besides enduring the rigors of operating in various African locations, the company's DSC cells were used to generate electrical power for British explorer Robert Swan and his team during their two-week 'E-Base Goes Live' project in which they traveled to Antarctica. Despite poor sunlight, the cells contributed to the successful powering of satellite, digital and video conferencing and other communications equipment throughout the two-week long expedition.\n\nThe first person to walk to the North and South Poles, Swan is moving on to an educational sailing around the world project and G24i is working on sails for his craft that will have thin-film dye-sensitized PV cells embedded in them. \n

The World Watch Institute (WWI) released a report last week stating that an estimated 2.3 million people worlwide work in the renewable energy industry or its supplier industries.

"In my personal opinion, most plants are unlikely to actually cut back because of profit factors. The smelters agreed to cut back mainly because of tight power and high power costs, but for some, supply is not much affected, only costs have gone up. But the cost of shutting down and restarting might be even higher than the increased power prices," a source from Shaanxi Tongchuan aluminum said July 11. A source from Chuangyuan aluminum said, "We also signed the agreement, but that's just a piece of paper; there is no definite ruling to say we must cut output. We have no plans to cut output at the moment or in the short term, but we may consider cutting back in the future." The Chuangyuan source also cited the power versus shutdown cost ratioand noted that in any case the company has its own power plant. "We don't expect many of the other smelters at the meeting to cut either, including Chalco ... everyone will wait and see," he said. "Domestic prices have risen slightly, but mainly affected by the rise on the LME yesterday - there seems to be little fundamental impact within China itself," an analyst from Beijing Antaike said July 11. "People are all very uncertain and maybe confused now since there are no definite details on what the cutbacks will be." A Chinese trader said domestic demand and trade activity were also expected to slow due to the Olympics, and those plants that actually shut may be able to restart in the fourth quarter, so the impact on domestic prices would be minimal.

Hydrogen fuel-cell cars have received a great deal of attention over the years as a clean alternative to petroleum-based transportation, producing only water for exhaust. Certainly the technology is known. Demonstration vehicles have been produced by several manufacturers and Honda is starting to roll out a fleet of 200 FCX Clarity fuel-cell cars, available for lease to select customers for US $600 per month. These autos are costing Honda hundreds of thousands of dollars each though, according to Honda's president Takeo Fukui (Wall Street Journal, June 16 2008), and it will take another decade before their cost falls below US $100,000. Although fuel-cell cars remain a long way from providing commercially viable transportation for the vast majority of people, cars are not the only application for fuel cells. Fuel cells are reaching commercial viability sooner in other applications such as portable electronics, including laptops, cell phones, MP3 players and games, aiming to supplement the ability of batteries to power these mobile devices for extended periods of time. There are a number of reasons why fuel cells may prove more competitive in portable electronics than in cars, including the favorable cost, lifetime requirement and easier distribution in this market. One of the companies developing fuel-cell technology for portable electronics is Polyfuel, using its proprietary hydrocarbon membrane technology for direct methanol fuel cells. The cost of power for portable electronics, according to Polyfuel president and CEO Jim Balcom, is up to US $10,000 per watt, compared with US $20-50 for autos, making portable electronics a much more attractive market than cars initially.

measures to encourage the greater use of energy efficient mortgages (EEMs). Such mortgages allow people to purchase or refinance their principal residence and incorporate the cost of energy efficiency improvements into the mortgage.

Of course, consumers can currently invest in energy efficient technology (or anything) using mortgage funds. However, the EEM is an important concept. This is because it may offer funds above a usual individual mortgage limit. Therefore, this additional money can provide guaranteed funds to grow demand/the efficiency market.
