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 lives of people today can't be imagined without mobile apps. And the growing popularity of mobile apps influences many startups to create their own app. But many similar apps are available in the market, so it's essential to know how to create unique mobile apps. Here we will discuss some mobile apps for startups with some new ideas for the app.

For several years, we've been watching breakthroughs and ideas in the world of digital paper / e-paper / electronic ink. The concept is that paper thin digital screens will eventually redefine our consumption of paper and applications for display technology

""NEMA thanks Representatives Ellmers and McNerney for their leadership in introducing HR 2244, and we appreciate the support from Energy and Commerce Committee Chairman Fred Upton and Energy and Power Subcommittee Chairman Ed Whitfield for including it in their grid modernization discussion draft. This much-needed legislation would direct the Department of Energy to produce a plan to create a strategic transformer reserve program, an idea supported by NEMA and its members as a way to bolster the United States' capacity to respond quickly to the loss of one or multiple large power transformers," "

"The retirement of experienced copper industry executives and the lack of trained technical replacements is helping to drive substitution and is likely to lead to more mergers and acquisitions as the industry adapts, senior industry executives said. A group of panelists at Metal Bulletin-American Metal Market's copper seminar in New York this week said that the copper sector needed to be far more proactive in attracting new talent and ensuring the gap in the professional supply chain is filled. "One thing that is driving substitution is the retirement of engineers that were very tied into the thought that copper wiring was the only alternative and that aluminium was unsafe," said Stu Thorn, CEO of Southwire. Thorn said the idea that aluminium was unsafe "almost became a psychological obsession" despite the development of new technologies to make it safe. "Now that generation of engineers is retiring, the new generation coming up doesn't necessarily have that same level of bias [towards copper], but what they do have is the drive to make more money, to reduce costs, and find cheaper alternatives," he told the seminar. "There is a shift..."

"Four years ago, the German government pledged the idea of bringing one million electric vehicles (EV) to the German roads by the year 2020. Today, approx. just 24.000 electric cars cruise the streets of Germany - a far cry from the ambitious goal once set. The published progress report of the German National Platform for Electric Mobility (NPE) was supposed to be a milestone."

You've heard of hybrids, electric cars and vehicles that can run on vegetable oil. But of all the contenders in the quest to produce the ultimate fuel-efficient car, this could be the first one to let you say, "Fill it up with air." That's the idea behind the compressed air car, a vehicle its backers say could achieve a fuel economy of 106 miles per gallon. Plenty of skepticism exists, but with many Americans trying to escape sticker shock at the gas pump, the concept is generating buzz. The technology has been the focus of MDI, a European company founded in 1991 by a French inventor and former race car engineer. New York-based Zero Pollution Motors is the first firm to obtain a license from MDI to produce the cars in the United States, pledging to deliver the first models in 2010 at a price tag of less than $18,000.

The lab has a lofty vision: "Enable one person to invent and run the next revolutionary IT service, operationally expressing a new business idea as a multi-million-user service over the course of a long weekend."

Nanowires being used for memory is hardly a new idea, but a group of researchers at the University of Pennsylvania seem confident that they've found a way to leapfrog the competition, and shake up storage devices as we know them.

The idea is to create a common set of communication protocols and data formats that utilities and smart-grid start-ups can adhere to.

They've developed a miniature refrigeration system small enough to fit inside laptops. Unlike conventional cooling systems, which use fans to cool chips down to ambient temperature, these small refrigerators will cool them below surrounding temperatures. It is an interesting idea to get compressors instead of fans in our laptops, but these tiny fridges are still more expensive than fans.

The government is considering levying up to 10 per cent cess on royalty charged on minerals like iron ore, copper and lead that would be used to promote scientific mining practices - an idea opposed by the mining industry.

""On a fundamental basis, at the moment, the market is still extremely well supplied with material," Matthew Wonnacott, a senior consultant at CRU Group in London, said in a telephone interview. "There's really no reason why anybody should need to withdraw material from an exchange for consumption. Demand in the market is just disappointing this year. It's not just China, in general demand is poor.""

Latvian flag carrier airline airBaltic has launched an international design contest inviting architects to submit design concepts for a new terminal at Riga International Airport in Riga, the capital of Latvia.
