Technology has been reinventing many machines and systems in different areas. Recently several researchers have developed turbines capable of converting the energy generated by the movements of water into clean renewable energy.
These Japanese researchers, who belong to the Okinawa Institute of Science and Technology (OIST), have been looking for ways to harness the sea water currents flowing along the eastern coasts of Taiwan and southern Japan.
These use submerged turbines which are anchored to the seabed and connected with mooring ropes that convert the kinetic energy of the sustained natural currents into usable electricity, which goes to dry land later.
Apparently, the team has been successful in getting clean renewable energy through the turbines and are ready to continue improving and expanding its technology.
The main feature of this technology is in its infrastructure. It is made with cheap class materials and is made so that the maintenance is quite accessible and easy to do.
Simple and adapting designs
The designs of the turbines are quite simple since these must adapt to the changes of the ocean waves. The turbines have been installed at strategic points so that they generate the energy efficiently and at the same time protect the coast acting as security barriers.
Currently, these turbines are located in a small part of the entire Japanese coast, generating up to 10 gigawatts of energy, which is equivalent to the production of 10 nuclear power plants. The location of the turbines receives the waves necessary to make them generate clean renewable energy.
In addition, they play the role of protective barriers by helping to prevent coastal erosion.
The design of the turbines allows them to withstand the force produced by the waves while converting the energy even when the waves may be stronger than usual, or in the event of storms or tsunamis.
The blades are designed with resistant materials inspired by the fins of the dolphins, are flexible and can release structural tension, unlike others that are very rigid and can break. The support of the blades is also flexible, its flexibility is very similar to that of a flower that folds when the wind hits it; the turbines have the ability to bend also to adapt to the waves, and these are doubled along the anchoring axes.
However, they have this design because they must remain at a constant speed so that animals or other things that can pass through them survive.
