Wave power trial could be held at Falmouth
8:30am Monday 30th January 2012
A Devon inventor's “motion from the ocean” electricity from seawater generator could be tested at Falmouth.
Energy firm Ecotricity wants to develop a commercial Searaser and put hundreds around the coast in five years.
The announcement coincides with moves by the Department of Energy and Climate Change to make the South West of England the silicon valley of Marine Energy technology.
The Searaser machine works by using wave energy to pump water up to container tanks, as waves move the buoys up and down, a piston works like a bicycle pump to send seawater through a pipe to an onshore turbine.
It is then released to hydro-electric turbines, producing electricity. Seawater can also be pumped into coastal storage reservoirs, and then released through a generator as and when needed.
Inventor Alvin Smith, who came up with the idea while he was playing with an inflatable ball in a swimming pool, said the main barrier to making wave-power efficient and therefore cost-effective – was resilience against the hostile ocean environment.
“Most existing wave technologies seek to generate electricity in the sea itself. But as we know water and electricity don’t mix – and seawater is particularly corrosive – so most other devices are very expensive to manufacture and maintain.“But Searaser doesn’t generate the electricity out at sea. It simply uses the motion of the ocean swell to pump seawater through an onshore generator.”
Mr Smith said that some of the infrastructure is already in place with over 150 reservoirs on cliff tops already around the south west.
A full size machine would be about one metre wide and 12 metres deep, and cost up to £250,000.
The ideal site for machines would be in water about 25m deep near a cliff face and there are hopes a test machine will be installed off Falmouth by the end of the year.
An area off Falmouth, called the Fabtest site, has been designated in 2011 for wave testing machines.
Mr Smith said while there would be no trawling around them, there would be no trouble with line fishing or lobster pots.

I proposed the idea of clifftop reservoirs earlier in this thread

as a means of 'storing' surplus wind energy from turbines for when it was calm. |

And on the north coast:
Wave Hub in Cornwall gets first energy device
A wave energy firm has agreed to install the first device at the Wave Hub off the north Cornwall coast.
Irish firm Ocean Energy expects to deploy a full-scale device at the hub by the end of 2012.
It said an offer by the South West Regional Development Agency to match the cost of its deployment expenses up to £1m was critical to the deal.
The Wave Hub, an electrical "socket" for testing wave energy machines, was put on the seabed off Hayle in 2010.
Ocean Energy's OE buoy generates electricity from a turbine turned by air being forced by wave action through a chamber.
It will send the electricity via a cable to the Wave Hub, which is linked to the coast by another electric cable laid on the seabed to a substation at Hayle.
Cork-based Ocean Energy has been testing a quarter-scale prototype of its buoy in Galway Bay for three years.
John McCarthy, chief executive and co-founder of Ocean Energy, said the offer of up to £1m match-funding from the Regional Development Agency (RDA) was "critical" to the firm choosing Wave Hub.
He said: "I cannot say that we would not have taken the decision to use Wave Hub without the cash, but it was very important.
"It also showed that the RDA is serious about making Wave Hub a major player in wave energy testing."
Wave Hub general manager Claire Gibson said: "By supporting Ocean Energy's deployment now we can fully test our operational procedures."
Ocean Energy's decision means that two of Wave Hub's four berths off Hayle on the north coast of Cornwall in south-west England have been reserved.
US and UK-based Ocean Power Technologies (OPT) has signed a "commitment agreement" to deploy its PowerBuoy device, although no date has been fixed.
An OPT spokesman said: "The company has projects all over the world.
"South-west England remains a core area of interest but a decision to deploy depends on the business case."

I'm going down to Hayle again today to watch progress in the bridge being built across Copperhouse Creek. The presence of Wave Hub in the area must be an important part of the reason for spending millions on a bridge that only gives access (at present) to a road about a mile long! |

Floating wind farm study launched in Cornwall
A £25m floating wind farm could be built off the coast of Hayle in west Cornwall, it has been announced.
The Energy Technologies Institute (ETI) is funding a feasibility study on using the county's wave hub facility.
The hub is the world's largest wave energy test site which was put on the seabed off Hayle in 2010.
The study into the hub's suitability for the wind farm proposal is expected to be completed before the summer.
If it proves successful, the project would see the design, construction and installation of a floating turbine by 2016.
Wave Hub general manager, Claire Gibson, said: "The ETI is looking at funding a single turbine project which would be on a floating platform, to be able to establish if it would work.
"Then hopefully they would be looking to fund more of those floating turbines."
Dr David Clarke, ETI's chief executive, said: "The concept for the floating platforms is to be able to access near-to-shore, high wind speed sites off the west coast of the UK, which would bring down the cost of generating electricity, so the Wave Hub site offers some interesting possibilities."
Miss Gibson added: "We have a particular advantage in that the offshore grid infrastructure and onshore substation are already in place, and we also have a team that has experience of managing the design, consent and installation of offshore energy projects.
"We clearly need to consult with a wide range of groups and other sea users about this opportunity and this forms an important part of the study."

Cornwall village Ladock generates green energy profit
A village in Cornwall that installed green energy devices a year ago is distributing £20,000 profits to the local community.
Ladock has modified 12 buildings, including homes, with solar panels, biomass boilers, ground-source and air-source heat systems.
The profits have come from national grid feed-in tariffs, which are paid to UK producers of renewable energy.
The village is also considering hydro-electric energy systems.
Low Carbon Ladock was formed in Autumn 2010, after Ladock and Grampound won £500,000 in a government-run competition, the Low Carbon Communities Challenge.
Its first profits are being allocated to Grampound Road playing field, a safer road crossing at Ladock School and more renewable energy devices in local homes.
Group chairman Chris Jones said: "We hope our donation to the community will be that kind of order every year.
"We are trying to increase our ability to earn money and benefit the whole community as well."
He said it was now working with a not-for-profit wind turbine company to build a turbine that could earn the group £25,000 a year.
The government wants to halve the feed-in tariff payments made to households with renewable energy sources because it says they are unsustainable.
However, Mr Jones said that would not affect the group's profits.
He said: "The cost of solar energy is coming down, so the ratio of what you spend and earn is quite similar."

£20m wave energy competition unveiled
The prize money will be shared between two winners, who will develop the first wave and tidal devices to sit in array formation
Madeleine Cuff
guardian.co.uk, Thursday 5 April 2012 15.47 BST
Companies making devices that generate renewable energy from the ebb and flow of tides and waves around the UK could win a share of a new £20m government prize announced on Thursday.
It is hoped the scheme, the Marine Energy Array Demonstrator (Mead), will encourage growth in the industry, which has been struggling to create a commercially viable projects. Ministers believe wave and tidal power could in the future generate up to 20% of Britain's energy needs and create 10,000 jobs in the sector.
The energy and climate change minister, Greg Barker, claimed Mead would help move the industry into the next stage of development. "This will take us one vital step closer to realising our ambitions of generating electricity from the waves and tides, powering homes and businesses across the whole of the UK with clean, green electricity," he said.
The prize money will be shared between two winners, who will develop the first wave and tidal devices to sit in array formation - much like clusters of wind turbines create a windfarm.
Pelamis, a leading wave technology company based in Scotland, said it intended to enter the competition. A spokesperson for the Scottish-based company said: "The prize will provide much needed capital support to the industry. The increasing activity and utility support demonstrates a real excitement within the sector as the technology matures towards commercial deployments."
As an island situated in choppy waters, Britain is well placed to become a world leader in wave and tidal technology. Of the eight full scale prototype devices installed around the world, seven are in UK waters, and about half of the world's leading marine technology companies are based here. But there is a growing fear that Britain will lose its early lead in the race to harness the power of the sea.
In February MPs called on the government to increase their support of wind and wave technology, claiming the UK could be overtaken by competing countries if it did not continue to provide subsidies and support to the industry.
The funding was welcomed by the UK's professional body for the renewable wind and marine industry, RenewableUK. David Krohn, the organisation's wave and tidal development manager, said: "The marine energy industry has the potential to allow us to generate clean electricity using the inexhaustible power of the sea. The Mead scheme will help kickstart the industry."
Yet Krohn claimed more money would still be needed if marine technology was to reach its full potential. "Our research shows that £120m of capital support is required to overcome barriers to commercial development and unlock our share of this global industry," he said. "It is important to recognise that this is only the beginning of the road to building marine energy into a fully commercial industry."
Pelamis agreed further support was needed. "To truly support marine renewables through to commercialisation will require project investors to be able to access substantially larger amounts of Government support over the coming years."
Companies can enter the competition online via the Decc website. The closing date for applications is 1 June 2012.

First of all, the article talks mostly about getting oxygen and hydrogen from water.
But about CO2, "They make it possible to use sunlight to convert carbon dioxide into various fuels, such as methanol."
However, carbon fuels are only useful when burnt, which gives back the CO2 - it would be a cyclic process. In effect, we'd be using the energy of the sun via photsynthesised fuels. The CO2 levels would remain constant - which contrasts with the burning of fossil hydrocarbons, which do add CO2 to the atmosphere. |

That's true, if artificial photosynthesis is confined to producing fuels; the CO2 level would remain constant. But such a useful process could be used for more than just making fuel.
Carbon makes a wide range of useful building materials; we could create almost all the infrastructure needed for our civilisation from carbon allotropes and compounds of one form or another, simply by extracting the material from the air by artificial photosynthesis. Eventually the CO2 would run out and plants would start dying (this is likely to happen naturally at some point in the next billion years anyway).
We could extract more carbon from chalk and limestone to make up the shortfall, so that wouldn't exactly be a show stopper. In fact by releasing carbon dioxide into the atmosphere near carbon mines it could be carried round the world for free by the wind to the point of use, reducing transport costs. |

Giant tidal turbine 'performing well' in tests off Orkney
A subsea turbine which uses tidal power to generate electricity has successfully completed initial tests off Orkney.
The turbine was lowered into position during winter storms and Scottish Power Renewables said it was performing well.
The 100ft-high 1MW (megawatt) Hammerfest Strom HS1000 device is already powering homes and businesses on the island of Eday.
There are plans to create a 10MW tidal power array in the Sound of Islay.
Testing began in December and has been designed to finalise the timetable for the Islay project, with machines being installed "as early as feasible" between 2013 and 2015.
Keith Anderson, SPR chief executive, said: "The performance of the first HS1000 device has given us great confidence so far. Engineers were able install the device during atrocious weather conditions, and it has been operating to a very high standard ever since.
"We have already greatly developed our understanding of tidal power generation, and this gives us confidence ahead of implementing larger scale projects in Islay and the Pentland Firth.
"Scotland has the best tidal power resources in Europe, and that's why we are seeing world leading technologies tested here."
The turbine can be monitored from the European Marine Energy Centre (EMEC) base in Eday, but engineers can also operate and inspect the device from Glasgow using mobile connections and an on-board camera.

Conservative thinktanks step up attacks against Obama's clean energy strategy
Confidential memo seen by Guardian calls for climate change sceptics to turn American public against solar and wind power
guardian.co.uk, Suzanne Goldenberg US environment correspondent. 8 May 2012
A network of ultra-conservative groups is ramping up an offensive on multiple fronts to turn the American public against wind farms and Barack Obama's energy agenda.
A number of rightwing organisations, including Americans for Prosperity, which is funded by the billionaire Koch brothers, are attacking Obama for his support for solar and wind power. The American Legislative Exchange Council (Alec), which also has financial links to the Kochs, has drafted bills to overturn state laws promoting wind energy.
Now a confidential strategy memo seen by the Guardian advises using "subversion" to build a national movement of wind farm protesters.
The strategy proposal was prepared by a fellow of the American Tradition Institute (ATI) – although the thinktank has formally disavowed the project.
The proposal was discussed at a meeting of self-styled 'wind warriors' from across the country in Washington DC last February.
"These documents show for the first time that local Nimby anti-wind groups are co-ordinating and working with national fossil-fuel funded advocacy groups to wreck the wind industry," said Gabe Elsner, a co-director of the Checks and Balances, the accountability group which unearthed the proposal and other documents.
Among its main recommendations, the proposal calls for a national PR campaign aimed at causing "subversion in message of industry so that it effectively because so bad that no one wants to admit in public they are for it."
It suggests setting up "dummy businesses" to buy anti-wind billboards, and creating a "counter-intelligence branch" to track the wind energy industry. It also calls for spending $750,000 to create an organisation with paid staff and tax-exempt status dedicated to building public opposition to state and federal government policies encouraging the wind energy industry.
The proposal was reviewed by John Droz Jr, a senior fellow at ATI, for discussion at the Washington meeting, which he also organised. ATI's executive director, Tom Tanton, said Droz had acted alone on the memo, although he confirmed he remains a fellow at the thinktank.
Droz is a longtime opponent of wind farms, arguing that the technology has not yet been proven and that wind technology should not receive government support. He claims 10,000 subscribers to his anti-wind-power email newsletter.
In a telephone interview, Droz said the Washington strategy session was his own initiative, and that neither he nor any of the participants had been paid for attending the session.
Their main priority was co-ordinating PR strategy. "Our No 1 reason for getting together was to talk about whether there should be agreement to talk about a common message."
The strategy session is the latest evidence of a concerted attack on the clean energy industry by thinktanks and lobby groups connected to oil and coal interests and free-market ideologues.
ATI is part of a loose coalition of ultra-conservative thinktanks and networks united by their efforts to discredit climate science and their close connections to the oil and gas industry, including the Koch family. Those groups include the Heartland Institute, the John Locke Foundation, and Americans for Prosperity, the organising arm of the Tea Party movement.
ATI is a relatively new entrant, coming to national attention only last year when it filed lawsuits against climate scientists including Michael Mann and James Hansen.
Campaign groups and spokespersons for the wind industry say there has been a sharp rise in organised opposition since early 2009 when Obama put investment in renewable energy at the heart of his economic recovery plan.
"We do see evidence of co-ordination," said Peter Kelley a spokesman for the American Wind Energy Assocation. "The same rhetoric pops up all over the place. Things that are disproven, that are demonstrably untrue, continually get repeated."
Recent developments in the campaign against wind power include:
• A new $6m election ad buy by the ultra-conservative group Americans for Prosperity attacking Barack Obama's support for wind and solar power.
• An email and telephone campaign by the American Legislative Exchange Council and Americans for Tax Reform to repeal or alter clean energy mandates requiring electricity companies to get a share of their power from renewables.
• Putting forward Alec-drafted bills overturning those measures in Michigan, Ohio, West Virginia, Colorado, Montana and Washington state.
Droz, in the telephone interview, confirmed that he had enlisted support for telephone campaigns from Americans for Prosperity and FreedomWorks – both of which have received funds from the Koch family. He also appeared at an anti-wind forum sponsored by the John Locke Foundation in North Carolina last December.
But he dismissed any idea of a co-ordinated effort. "We happen to have common interests on some things," he said. "But it's not collusion."
But conservative activists describe the ramp-up as critical to the effort to defeat Obama in the elections. "It's absolutely a campaign issue and it's a big one," said Dave Schwartz, who heads the Maryland chapter of Americans for Prosperity, a tea party group with Koch funds. "It absolutely is a contentious issue," he said.
Kert Davies, Greenpeace research director, agrees. "They are going back to the states to create the space for an anti-Obama, anti-green energy thing. It is really a political attack," he said. " What the right wing wants to perpetuate is that this is a type of energy that never works and requires massive government handouts."
More than 30 local wind farm opponents, all selected by Droz, came to Washington at his invitation. Participants included members of conservative groups such as Committee for a Constructive Tomorrow and Tea Party Patriots.
A number said they had come to DC for strategy tips and PR advice. Three used the same phraseology as Droz who said the decision to meet and pool strategies was to avoid having to continually "reinvent the wheel".
"Everybody is amateur and everybody is learning from the ground up and re-inventing the wheel and the discussion among some of us was as to whether or not we could be a little more efficient and share resources and information," said Carolyn Gerwin an attorney and Tea Party activist from Pontiac Illinois who was among the participants.
Gerwin has been active in both Illinois Wind Watch and the Tea Party Patriots, and lobbied against wind energy at the state and federal level, her sign-in questionnaire for the February meeting said. "I'd like to see us develop a nationwide network of wind warriors that can be mobilised on very short notice," she wrote in a questionnaire distributed to participants.
There is evidence that network is already coming into being. Since the meeting, participants have pooled efforts to make phone calls and send email to members of Congress.
Opposing Obama's energy policies was a natural fit for conservatives, said Marita Noon, a conservative activist from New Mexico who was at the meeting. "The American way, what made CostCo and Walmart a success, is to use more and pay less. That's the American way," The president's green policies however were the reverse, she said.
"President Obama wants us to pay more and use less."
That set the stage for a confrontation over wind farms and other clean energy issues in the elections, Noon argued. "I would say it's almost the issue," she said. "It's going to be huge." |

Some familiar vested interests involved. Note use of catchy phrases and talking points. Another well planned campaign of disinformation.

My new version of AGW is that is caused by hot air from US right-wingers. 
They're just tilting at windmills! 
| Quote: | Tilting at windmills is an English idiom which means attacking imaginary enemies. The word “tilt”, in this context, comes from jousting.
The phrase is sometimes used to describe confrontations where adversaries are incorrectly perceived, or to courses of action that are based on misinterpreted or misapplied heroic, romantic, or idealistic justifications.

I hope the American public can see through this nonsense. |
