Ireland's OpenHydro and Germany's RWE are spending millions to try to turn the power of waves into electricity With oil prices hitting almost daily record highs and global warming climbing up the public agenda, the need for alternative energy sources has never been more urgent. But while wind and solar have dominated the recent rush to invest in renewables, market watchers reckon it could now be marine energy's turn to shine. Ocean power-using the energy from waves or tidal flows to produce electricity-is quickly coming of age as a viable green resource that could help meet ambitious global targets to reduce greenhouse gases and dependency on fossil fuels. European and North American power companies such as Canada's Emera (EMA.TO) and Germany's RWE (RWEG.DE) are spending millions to fund wind and tidal projects. This investment has led to a new generation of more efficient technologies, with dozens of prototypes expected to be ready for commercial deployment within the next five years. "There's huge interest in both wave and tidal technology," says Thomas Boeckmann, clean tech analyst at market research firm StrategyEye in London. "It's gaining a lot of attention from energy companies, which will be able to offer financial backing and technical expertise to these startups."

It's been a long, challenging endeavor, but there are signs that the economic ecosystem built up around wave and tidal power generation is at long last gathering enough momentum to make the jump from R&D-driven to full-fledged commercial industry. Scotland, with its long stretches of west-facing coastlines, North Atlantic latitude and longstanding tradition of maritime engineering and commerce, is now at the leading edge of change when it comes to fostering development of marine renewables. Wavegen's Limpet 500 system has been pumping electricity from the western Scottish Isle of Islay shoreline since 2000 while the company and project developer npower renewables have continued to move forward with plans to develop the Siadar Wave Energy Project, potentially the first under the Scottish government's Marine Supply Obligation program. Marine Current Turbines is getting ready to flip the switch and fully commission a grid-connected 1.2-megawatt (MW) Seagen tidal turbine-based system in Northern Ireland's Strangford Narrow, while elsewhere in the EU, project developers and the marine renewables community await the much-anticipated commissioning of Pelamis's novel, serpent-like wave power system off the northern Portuguese coast.

the top 4 contenders are: 1. Green building materials - I'm not sure it would be my thing, but investors across the board seem to think this area is ripe for a hit. 2. Carbon IT - With some sort of cap and trade a near certainty, the interest is picking up in one of the few areas in carbon that looks like a "venture bet". I should know, I have one of these companies myself. 3. Food related technologies - High food prices and rising fertilizer costs, what can I say? 4. N-generation solar technologies - Everyone not in the first wave is looking to get in to the 4th wave. Not sure venture investors will fare better in the 3rd or 4th wave than they did in the second, but they are going to try.

"But if nature was forced to use the pipes-and-ion-channels approach, that leaves us with plenty of scope for speeding things up using silicon and copper (and this is quite apart from all the other more exotic computing substrates that are now on the horizon). If we were simply to make a transition membrane depolarization waves to silicon and copper, and if this produced a 1,000x speedup (a conservative estimate, given the intrinsic difference between the two forms of signalling), this would be an explosion worthy of the name."

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

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.

"The team has developed a way to integrate fiber optics - glass or plastic components that can transmit data using light waves - into computer chips, replacing copper wires that rely on electricity."

A vote could come as early as this week in the U.S. Senate on a bill introduced by Senate Tax Committee Chairman Max Baucus (D-MT) and Senate Majority Leader Harry Reid (D-NV) containing a one-year renewable energy production tax credit (PTC) extension and a small wind turbine investment tax credit. The Senate bill, S. 3335, contains a one-year PTC extension at its current value. After December 31, 2009, any further extension would include the "presumption" of a cost cap, which would, through a complex formula, put a ceiling on the value of the credits of no greater than 35% of project value. The small wind ITC has a cap of US $4,000 per system.The 10-year cost for the PTC, including all technologies to which it applies, is projected to be approximately US $7 billion, while the ITC, which includes solar, would cost approximately US $907 million over 10 years. The bill also includes provisions to extend through 2014 the tax credits for solar energy, fuel cell and microturbine property, as well as the residential energy efficient property tax credit. Marine renewable energies could also benefit from the bill as credits to build wave, tidal, current and ocean thermal energy conversion systems of at least 150 kilowatts (kW) are extended through the end of 2011.

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

Norway's Energy Council, comprising business leaders and officials, said green exports could help the European Union reach a goal of getting 20 percent of its electricity by 2020 from renewable sources such as wind, solar, hydro or wave power.

Leadership in both the U.S. House of Representatives and Senate are calling on the Department of Energy (DOE) to allocate US $250 million of the $2.5 billion in stimulus funding for renewable energy research and development to the emerging marine renewable energy industry. The funding would help develop wave, current and tidal energy technologies

The technology is capable of carrying 10 times as much power as copper wires of the same size, while also being able to automatically adapt to power surges and disruptions from lightning strikes, heat waves, and traffic accidents, even sabotage. A single superconductor cable can replace 12 copper cable bundles, freeing up more space underground for other utility needs like water, natural gas, or phone service.
