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

Rio Tinto's proposal to raise $19.5bn from Chinalco is seen by the mining group's board members and shareholders as an "option" to follow if there are no superior alternatives in the next three months, according to some Rio shareholders.

According to NREL's Renewable Electricity Futures Study, the increased electric system flexibility needed to enable electricity supply-demand balance with high levels of renewable generation, can come from a portfolio of supply and demand side options, including: · Flexible conventional generation · Grid storage · New transmission · More responsive loads · Changes in power system operations

\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

It looks ordinary, like a razor-thin metal ribbon. But the high-temperature superconductor power transmission cable the Long Island Power Authority recently installed in Ronkonkoma revolutionizes how electricity is delivered, utility and federal officials said. The cable -- which is a fraction of the size of a traditional copper wire but can carry three times the power -- made its ceremonial debut yesterday with officials from LIPA, the U.S. Department of Energy and officials from the company that makes the cable. It went online April 22, the world's first use of the new technology in a commercial power grid. Utilities around the world are looking at superconductivity to improve efficiency of their grids and make them less vulnerable to blackouts. LIPA has buried three 2,000-foot wires in its right-of-way, and it will be installing a second generation of the wire in the same area as a test. "We view superconductor power cables as an important option that will help us further enhance the reliability of our grid as we meet our customers' increasing demands for electric power," LIPA chief executive Kevin Law said. He said the new cable allows the utility to increase capacity where its system has bottlenecks while increasing reliability and longevity and lowering costs. The wire, manufactured by American Superconductor Corp., conducts 150 times the electricity of the same sized copper wires, strand-for-strand. This means transmission cables can be far smaller and still conduct as much as three to five times more power in a smaller right-of-way.

MIT researchers have discovered a way to store solar energy that could make solar power in homes a mainstream energy option and might even make power companies obsolete, at least for residential needs.

August 12, 2008 What will the electric carInnovation-At-Big-Companies Dec-07 ownership experience be like? NissanNissan Motors has given us a glimpse of what early adopters are letting themselves in for - rather than bundling expensive, consumable battery packs into the price of the car, Nissan plans to sell its 2010 mass-market battery-electric car for around the same price as a standard petrol car, and lease the battery pack to the buyer on a monthly fee. And the battery lease plus electricity charges should still end up cheaper than a petrol bill. Don't worry, it won't look anything like the test vehicle pictured! In an encouraging auto industry trend, more and more major players are committing to launching hybrid, hydrogenhttp://en.wikipedia.org/wiki/Hydrogen and battery-electric carsElectric car in the next few years. Nissan is the latest to outline its plans, which will include a production-model lithium-ion plug-in electric car by 2010. There's also a clever high-tech hybrid on the way, and Nissan has also announced a cheaper way of building a high-power density hydrogen fuelGM-Coskata-Alternative-Fuels cell stack. But it's the imminent battery-electric vehicle (BEV) that offers the most immediate chance for car buyers to get away from gas stationshttp://en.wikipedia.org/wiki/Filling_station and look into green motoring. And while no details have yet been officially released about range, charging time, body shape or power, Nissan has clarified that its first mass-market BEV will use a lithium-ion battery pack from partner AESC - an expensive option, but the cost (and eventual replacement cost) will be spread out over a lease plan.

LONDON -(Dow Jones)- A pre-feasibility study at the Pebble copper project in Alaska is underway, with assessment of all options expected during 2009, the project's joint venture partner Anglo American PLC (AAUK) said Thursday.

Andrew, the CommScope, Inc. division that is a global leader in communications products and systems, has introduced HELIAX(R) 2.0, the world's first complete cable and connector family for wireless networks, which offers operators and OEMs new radio frequency (RF) transmission line options under a trusted brand.

KME Group SpA, a leading copper and copper alloy semis maker based in Italy, will buy 30% of Sigimet SpA, an Italian ferrous and non-ferrous metals trader. The company also bought 30% of Italian scrap metals trader Metalbuyer in February. In both cases, KME holds the option to raise its share. Considering that the company relies on scrap for more than 50% of its metal input, the acquisitions will lead to a reduction in supply costs. The company said that the acquisitions will benefit industrial activity, however, the main objective was diversification rather than integration.

But today the scenario is different, with builders getting a mix of mid end and affordable housing into their portfolio. Raminder Grover, CEO-Homebay Residential, Jones Lang LaSalle Meghraj, says the revival in sales has been, conservatively speaking, to the tune of around 25% across the mid-to-high income segments, according to his company's sales records. Rohtas Goel, CMD of Delhi-based Omaxe too says there has been a 30% increase in sales thanks to factors such as a reversal in general economic sentiment after the elections and more options available in affordable housing. Statistics too would appear to bear this out. India's largest real estate developer DLF says it has sold almost 1,500 flats in various cities since April, notably some 400 flats in its mainstay market Gurgaon, 700 in Bangalore, 100 plots in Indore, 200 flats in Hyderabad and 50 in Cochin. Rival Unitech has managed to sell more than 4,000 units in the last two and a half months in the National Capital Region, Chennai and Mumbai. Omaxe has also sold almost 500 apartments in its Omaxe Eternity project in Vrindavan.

The benefits for the market are obvious. Regional, ownership unbundled transmission/ infrastructure companies have a natural incentive to maximise the offering of capacity to the market, as this is the sole mechanism through which they achieve their revenues. They will be happy to invest to meet market demand. With their large scale and regional approach they can pass through the benefits of synergies and eliminate unnecessary interfaces. Finally, as they do not have any potential conflict of interest with supply or production interests, regulation can be lighter, decreasing the regulatory and administrative burden and increasing efficiency even further. Time will tell, but it seems that the ITO option has its greatest potential for those companies that can not afford to sell their transmission networks under the current economic conditions or that are opportunity constrained and have no suitable investment potential. In any event, the conclusion must be that, whereas full ownership unbundling has not been directly achieved through the Third Package, it would appear that the scene has been set for a market structure that will move gradually but inevitably into the direction originally envisaged in the Commission proposals. So was it worth it? For you to judge.

"This approach offers an optimized total cost of ownership (TCO) compared to traditional options. "
