This summer, in August, a world of tech, invites you on a technological and digital safari to discover innovations from all continents. The new destination proposed by the Netexplo Observatory, a French organization which unveils and rewards inventions every year, takes us to the deep sea, in which Norwegian engineers are experimenting with an ultra-efficient offshore wind turbine.
After the warm waters of Indonesia, our innovation exploration vessel criss-crosses the Atlantic Ocean and lands on the coast of Norway! To discover that the engineers of the Norwegian company World Wide Wind offer a radically different approach to offshore wind energy, explains Sylvain Louradour, the associate director of theNetexplo Observatory : « These vertical axis wind turbines, which have two sets of blades, are set to rotate in the opposite direction. They promise to double the production of today’s largest turbines. The other particularity of these maritime wind turbines is that they are floating and that no concreting work, which can destroy the fauna and flora, is necessary to install them. »

Offshore wind is becoming more efficient than onshore turbines
These wind turbines with their advanced design offer much better wind resistance than usual turbines, specifies Hans Bernhoff, the technical director of World Wide Wind : « Concretely, this wind turbine has two rotors on the same mast. The generator is located at the bottom of the structure below the waterline and adapts to the wind. THE energy potential of offshore wind is much more important than on earth and we have developed the technology to exploit it fully. »
The sea, the wind and the gigawatts
World Wide Wind’s goal is to develop a wind farm with a capacity of 10,000 gigawatts, adds Hans Bernhoff: ” Our system makes floating offshore wind more competitive in terms of energy production, installation cost and durability. Today, we are looking at building wind turbines about 400 meters high and these very large machines will produce a total of 10,000 gigawatts. Unlike today’s OEMs who stick to more traditional designs that are very different from our design. »
Double the production of today’s largest turbines
The structure of these wind turbines has been specifically studied to allow their rapid installation at sea. World Wide Wind plans to deploy a first 3 MW model which would be operational by 2026, then another much larger turbine with a power of 40 MW from 2029.
The next Monde De Tech will make a stopover in Canada, to meet artificial intelligence researchers developing AI programs to promote international cooperation in the fight against climate change.
