Giant tidal turbine 'performing well' in tests off Orkney

BBC News, 17 May 2012

The BBC's David Shukman says installing the giant turbine beneath the
stromy waters was an "extraordinary" operation

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.

The turbines are placed on the seabed

“…  4 - Energy (again)

The natural resources of the planet are finite and will not support the continuation of what you've been doing. We've been saying this for a decade. Watch for increased science and increased funding for alternate ways of creating electricity (finally). Watch for the very companies who have the most to lose being the ones who fund it. It is the beginning of a full realization that a change of thinking is at hand. You can take things from Gaia that are energy, instead of physical resources. We speak yet again about geothermal, about tidal, about wind. Again, we plead with you not to over-engineer this. For one of the things that Human Beings do in a technological age is to over-engineer simple things. Look at nuclear - the most over-engineered and expensive steam engine in existence!

Your current ideas of capturing energy from tidal and wave motion don't have to be technical marvels. Think paddle wheel on a pier with waves, which will create energy in both directions [waves coming and going] tied to a generator that can power dozens of neighborhoods, not full cities. Think simple and decentralize the idea of utilities. The same goes for wind and geothermal. Think of utilities for groups of homes in a cluster. You won't have a grid failure if there is no grid. This is the way of the future, and you'll be more inclined to have it sooner than later if you do this, and it won't cost as much.

Water

We've told you that one of the greatest natural resources of the planet, which is going to shift and change and be mysterious to you, is fresh water. It's going to be the next gold, dear ones. So, we have also given you some hints and examples and again we plead: Even before the potentials of running out of it, learn how to desalinate water in real time without heat. It's there, it's doable, and some already have it in the lab. This will create inexpensive fresh water for the planet.

There is a change of attitude that is starting to occur. Slowly you're starting to see it and the only thing getting in the way of it are those companies with the big money who currently have the old system. That's starting to change as well. For the big money always wants to invest in what it knows is coming next, but it wants to create what is coming next within the framework of what it has "on the shelf." What is on the shelf is oil, coal, dams, and non-renewable resource usage. It hasn't changed much in the last 100 years, has it? Now you will see a change of free choice. You're going to see decisions made in the boardrooms that would have curled the toes of those two generations ago. Now "the worst thing they could do" might become "the best thing they could do." That, dear ones, is a change of free choice concept. When the thinkers of tomorrow see options that were never options before, that is a shift. That was number four. ….”
