At this stage, there has been no convergence of technologies in the tidal energy sector. You would see different technologies like three blades, wind turbine type, and some other concepts like ours with no axis in the middle. It differs among technologies.
There are a lot of technological challenges to overcome in this industry. You rightly pointed to the fact that we are in the ocean where there is not only corrosion, but high flow, biofouling, and all of those technological challenges that we are trying to demonstrate through our first project at the FORCE test centre. That means we have a suite of sensors that monitor most of those challenges on the technologies themselves. That's where the demonstration projects are necessary because we get to see that over the lifetime of those tidal ranges, over 15 years, and check the predictions of all those changes every six months, five years, 10 years.
