World’s largest tidal power device unveiled in Scotland


A device thought to be the largest tidal energy turbine to be built in the world has been described by its developer as “simple and robust”.
Atlantis Resources unveiled its AK-1000 at Invergordon ahead of it being towed on a barge to a European Marine Energy Centre test site off Eday, Orkney…The device has two sets of blades to harness ebb and flood tides.
Mr Cornelius told BBC Scotland that the focus of the marine industry at the moment was making the Pentland Firth a huge success in terms of generating electricity from renewable energy devices…
“It is one of the harshest environments on the planet…In order to get a robust turbine we have had to make what we call ultimately the dumbest, simple but most robust turbine you could possibly put in such a harsh environment.”
The AK-1000′s two sets of blades have also been designed to move slowly underwater and Atlantis said they would not pose a threat to sea life…
Atlantis, which has bases in London and Singapore, has been leading a plan to use tidal energy to power a computer data centre in the far north of Scotland…
The computer data centre would provide services for a number of companies and be powered by tidal energy rather than depend on electricity supplied to the National Grid.
I guess this puts the Brits+Singaporeans – and anyone else putting such projects into play – years ahead of that great industrial and engineering giant, the United States.
Between Republicans who prefer to spend taxpayer dollars on their favorite war contractors and Democrats who are happy enough maintaining bureaucratic sinecures, the United States should regain a leadership position in the global economy – never.
Interior secretary Salazar approves Cape Wind

In a groundbreaking decision that some say will usher in a new era of clean energy, U.S. Interior Secretary Ken Salazar said today he had approved the nation’s first offshore wind farm, the controversial Cape Wind project off of Cape Cod.
“This will be the first of many projects up and down the Atlantic coast,” Salazar said at a joint State House news conference with Governor Deval Patrick. The decision comes after nine years of battles over the proposal.
“America needs offshore wind power and with this project, Massachusetts will lead the nation,” Patrick said.
The decision had been delayed for almost a year because of two Wampanoag Native American tribes’ complaints that the 130 turbines, which would stand more than 400 feet above the ocean surface, would disturb spiritual sun greetings and possibly ancestral artifacts and burial grounds on the seabed. The ocean floor was once exposed land before the sea level rose thousands of years ago…
“I am convinced there is a path we can take forward that both honors our responsibility to protect historical and cultural resources and at the same time meets the need to repower our economy with clean energy produced from wind power,” he said…
George Bachrach, president of the Environmental League of Massachusetts, hailed the decision, saying it was “a critical step toward ending our reliance on foreign oil and achieving energy independence. “
“Those who continue to resist and litigate are simply on the wrong side of history,” he said.
I have a personal past that shares in this decision. I grew up with subsistence fishing on the New England coast.
I understand those who assign primacy to viewscape, nature. But, New England tradition included folks who were daring enough to sail halfway round the world in search of new economies. That tradition accepted the inclusion of new ideas into the commercial and social life of old communities – from steam power to the abolition of slavery.
Those who see only mutually exclusive conflicts in renewable energy and their view of the horizon, those who believe their religion trumps the needs of the greater modern society – are stuck in the wrong century.
