Nowadays we are seeking more and more ways to harvest green energy and protect the environment. Part of the attention goes towards the sun and the moon. Scientists have already come up with various inventions able to gather solar energy. Others rely more on developing the means to harvest wind energy. And finally, there are some that turn their attention towards the sea and the tides. WaveNET is a new invention that is able to harvest energy from the waves.
WaveNET is made of a scalable array of floating generator units called “Squids.” These units harvest energy when their arms rise and fall in accordance to the tides. Every “squid” can be connected to three others. In this way they create a large net that floats on the waters of the sea and is flexible in any direction. Of course, as it grows, the grid of “squids” becomes more and more efficient. Albatern, the company based in Scotland that is behind this idea, aims to have a 1.25 kilometer-long grid that would be able to harvest as much as 100 megawatts by the year 2024.
Due to its unique setting as arrays, the WaveNET is able to gather energy from five of the six degrees of wave movement, those being: “pitch, roll, heave, surge and sway.” Moreover, this type of design makes it more resistant to damage. Some or even all of its array can be submerged and the system will suffer no issues. Apart from that, because most of the mechanics of the WaveNET take place under water, the visual impact of the system consists of a series of yellow buoys floating on the sea.
Albatern aims to build its 1.25 kilometer-long grid in the span of ten year, using an array of 135 units that are 24 m high. Apart from this model, the company also designed 6 m and 12 m units. Do you think the WaveNET will make an impact as a green energy source?
