The hywind project will be the first to utilize wind energy with the help of mobile offshore wind turbines * The ability to move the turbines to the strong winds in the middle of the sea will maximize the electricity production capacity
Around the world there are already wind turbines located in the sea far from the coast, but all the turbines are stationary and permanently attached to the seabed. The plan of a company StatoilHydro It is to connect the wind turbine to the buoy, using technology used by oil rigs, in order to create a mobile marine turbine.
Wind energy is green energy that will never run out. The use of offshore wind turbines saves investment in the purchase of real estate or land lease costs. Mobile marine turbines should further increase the flexibility of the operator by being able to move them at any given moment and place them in much deeper water where there are strong winds and thus utilize the full potential of each turbine.
According to the company, floating power plants are not mature enough to be used commercially on a large scale. This project will examine whether the technology is mature and whether it is commercially viable. The program will begin in the third quarter of 2008 and will last two years, at the end of which the company will evaluate the economic viability of the project.
The height of each turbine is 165 meters (of which 65 meters are above sea level), the weight is 5300 tons (the weight of the turbine alone - 138 tons) and its output is 2.3 megawatts. The investment in the project amounts to 400 million crowns (50.9 million euros, 80 million dollars).
The company has already stated in the past that it is interested in building a huge park of turbines in the heart of the sea, where each turbine will have the capacity to produce electricity for 1,000 households. Despite the desire, a turbine farm of this type is many years away from us, but this project, along with other projects that the company is implementing, show how determined the company is to implement this vision.

To the cool commenter:
You are right that the energy potential is high, but the problem is the ability to utilize it.
The height of the dam in a strong hydro-electric station is at least 100 meters, the height difference at high tide is at least 14 times smaller, so in order to produce the same amount of energy, the water flow in the generators has to be 14 times greater. This means that the amount of water that needs to be stored is enormous. There are many more shortcomings and problems that I will not mention.
Don't worry, if it was economical they would already have established many of these.
The electricity will reach the coast by cables
And how will the electricity reach the coast? in swimming?
Why is the use of dams to utilize tides for energy purposes rare?
Why are there hardly any countries that use this method? A method which in my opinion is very effective, very simple, very cheap (it is not that expensive to build a dam) and very predictable (cyclical).
A nice idea considering the fact that there are very strong winds in the sea areas and even more in the oceans, although it is necessary to invest in further development, the efficiency of these turbines can be greatly improved and even better than introducing insufficiently mature technology.
I would be happy to see such initiatives also in the field of utilizing sea wave energy, which is very powerful and can provide perhaps even more energy than wind turbines, I am not really sure about the numbers.
I am very happy to hear about investments all over the world in the field of renewable energies.
