Figure 8.2.2.1 illustrates the lengths of subsea cable that may be required year by year. It is based on expected device spacings, farm layouts and likely distances from offshore substaons to shore. The final lengths required will depend on exact site layouts and separaon distances between devices as well as the method of connecon between devices, which could have dedicated connecons to the transformer or be chained together. The chart has the same profile as that of the number of devices installed, but offset as cables are purchased in advance of installaon. Export cables installed as part of a project's inial phase may be specified with sufficient capacity to accommodate later phases as well.

That may be a little aggressive, but Princeton University engineers have developed a device that may change the way that we power many of our smaller gadgets and devices. By using out natural body movement, they have created a small chip that will actually capture and harness that natural energy to create enough energy to power up things such as a cell phone, pacemaker and many other small devices that are electronic.

"Copper interconnects have served the electronics industry since its infancy. Wire terminated with separable connectors enables equipment to be efficiently assembled as well as deliver power and signals to/from the host of electronic devices we take for granted today, but change is brewing. The explosion of mobile devices has begun to alter traditional connectivity with demand for interfaces that free the device from the tether of signal and power cables."

"University of Illinois researchers have developed heat-triggered self-destructing electronic devices, a step toward greatly reducing electronic waste and boosting sustainability in device manufacturing. They also developed a radio-controlled trigger that could remotely activate self-destruction on demand."

NEC Electronics America Inc. introduced to the Americas twenty-two new 16-bit All Flash microcontrollers (MCUs) for compact, low-power, battery-operated, and sensor-enabled systems. Based on NEC Electronics' high-performance 16-bit 78K0R CPU core, the new 78K0R/Kx3-L MCUs offer very low power consumption to extend battery life, and more on-chip integration to help reduce the size and cost of battery-driven and sensor-enabled systems, such as fire and security alarms, meters, industrial sensors, anti-shake digital cameras, handheld medical diagnostics devices, and data-logging and point-of-sale terminals. In addition to low power consumption, the new lineup offers high-performance on-chip oscillators, built-in circuits for sensor functions, and extended system operating time. "As environmental awareness has grown, energy-saving systems have become particularly reliant on MCU technology," said Jim Trent, Vice President, Multipurpose Microcontroller and Automotive Group, NEC Electronics America. "Over the past several years, NEC Electronics has delivered many ultra-low-power 8- and 32-bit MCUs that have met the demand for energy efficiency. With the introduction of the new 78K0R/Kx3-L devices, however, NEC Electronics is now delivering the benefits of energy efficiency in its 16-bit products."

Scientists at the U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL) have set a world record in solar cell efficiency with a photovoltaic device that converts 40.8% of the light that hits it into electricity. This is the highest confirmed efficiency of any photovoltaic device to date. The inverted metamorphic triple-junction solar cell was designed, fabricated and independently measured at NREL. The 40.8% efficiency was measured under concentrated light of 326 suns. One sun is about the amount of light that typically hits Earth on a sunny day. The new cell is a candidate for the space satellite market and for terrestrial concentrated photovoltaic arrays, which use lenses or mirrors to focus sunlight onto solar cells.

The trendspotters at JWT are predicting: - The mobile device as everything hub: Mobile rules. If you're a marketer, take note, made-for-PC sites don't make the cut for a mobile experience. - Customizable mobile: Apple's iPhone made mobile applications all the rage and other smartphone makers are having to follow suit. JWT says watch for more open mobile systems and an "onslaught" of mobile apps. - Decline of email: If you've tried emailing a teen lately you may have noticed that's considered only slightly less old-school than two tin cans and a string when it comes to communications. Text messaging, social networks like Facebook and Twitter are increasingly preferred by email recipients who are ready to cry uncle under the weight of their inboxes. According to JWT, after a decade of dominance, email will gradually be eclipsed by more efficient, manageable solutions. Hear, hear. - Cloud Computing: Software, storage -- everything we needed in our desktop computers or carried around in our laptops is now in the 'cloud.' Wikipedia calls the cloud a metaphor for the Internet, an explanation that is difficult to convey to new users. I found myself trying to explain this to a friend as I was helping her set up a netbook she received as a Christmas present. She wanted to know: Was it on the computer? On a disk? On a USB drive? I just waved my hands in the air and said 'it's all on the Internet now.' That, plus the appearance of 600 of her holiday photos on an online photo site seemed to convince her. - Social networking for jobseekers: With companies handing out more pink slips than Christmas bonuses in the past month or so, jobseekers who know how to maximize the benefits of such sites as LinkedIn and others will find those social networking skills could come in handy. - Web/TV convergence: This prediction has been paraded out in one form or another for quite a while and no telling if 2009 will be its year. The convergence of entertainment media on one viewing device

Part of the growing trend for nearly every electronic device to be able to communicate with others, smart grid and advanced metering startup Trilliant has taken $40 million in its first official venture funding.\n\nTrilliant, like competitors Ambient, Silver Spring Networks, SmartSynch and others, makes wireless communication devices for utility meters. When enough are present in an area, they can form a mesh network capable of communicating moment-to-moment use information back to utilities, and to the homes and businesses they're installed within. (Some can also communicate via hardwired connections.)\n\nThe company is one of the oldest to try to tackle the problem. I covered it in more depth in June. The problem with looking at the field is that, at first glance, all the contenders seem to be pretty much identical; broadly speaking, each is approaching the same problem, that of trying to get more information about usage to consumers and utilities, in more or less the same way.

"Carbon Nanotubes (CNTs) have not yet met commercial expectations from a decade ago, and now hot on its heels is graphene. Graphene is considered a hot candidate for applications such as computers, displays, photovoltaics, and flexible electronics. IDTechEx market forecasts indicate that CNT and graphene transistors may be commercially available in volume from 2015 onwards, according to the new report \"Carbon Nanotubes and Graphene for Electronics Applications 2011-2021\". According to IDTechEx, the biggest opportunity for both materials is in printed and potentially printed electronics, where the value of these devices that partly incorporate these materials will reach over $44 billion in 2021."

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 have been sharp technological advances in the auto sector, which requires highly functional copper," Keiichi Kobayashi, corporate senior vp, automotive and electronics material field, copper and high performance material products division, told Metal Bulletin sister title Copper Price Briefing.
