The wager of the next decades: the sea as a source of energy
Obtaining energy from the sea has been very difficult so far, especially because working at the bottom of the sea is not easy; the devices installed there will oxidize pidamente.De moment, in the world there are two plants that take advantage of the currents or the
movements of the tides. One of them, located in La Rance (France), has a power of 240 megawatts and the other, located next to South Korea’s Sihwa Lake, has a power of 254 megawatts. In these plants energy is obtained through wheels of a certain diameter. The currents move the wheels, and this movement generates electricity.
This year the system will be given a further boost: On the island of Ouessant in Brittany, a turbine of ten metres in diameter, at 55 metres in depth, will sail. Through it you will get a power of 1 megawatt. A further four turbines will be installed in the same location within two years, which is expected to cover 70% of the energy needs of the isla.Para by 2050, the
extension of this system to the whole world is foreseen. It is estimated that some 330,000 turbines will be installed at the bottom of the sea, generating a power of 334,000 megawatts. That is, 20% of the world's energy needs.

I don't know if we're hit by heat waves anymore, if it's a normal hypocrisy or a systemic logic, but the gap between what we know, what we say and what we do, beyond concern, surprises me, especially in a summer environment. News, research, social media interactions… constitute a... [+]
