Remote islands- well wave isn't set and forget and requires a skillbase to install, service and maintain so unless there is oil , rig support style industry accessible when required for installation, service and it is done on a scale to justify cost it won't be deemed reliable.
I wonder on what "numbers" any such analysis used as CCE surely never provided any numbers on real outputs, reliability, cost of ownership etc etc to shareholders. I don't mean modeled numbers but real output data achieved and sustained. It is really easy to throw out large imaginary numbers on the prospect that you will meet a particular efficiency and cost of production but you also need to be dealing with a company that will be around for the lifetime of the product and back it so a large partner is preferable.
Design - well other companies have wave and tidal in situ and producing power who can show real life production numbers with current scale operations showing ongoing costs and wear etc.
Many companies are quite fast at prototyping and implementing and testing in the real world rather than creating a computer model . Now I love the science of a computer model and understand the value of such but not at the cost of never having the end product. What I don't understand is why CCE didn't use their co-developed computer models ( if they were so special) to consult and charge all firms in similar fields for their proof of concept models of water dynamics, power etc and the whole wave industry would be better off as it would show a comparison of differing ideas. Why didn't this happen and just how good are the models and data - well competition companies partnered with large firms have access to research depts and models I guess and were doing it for results with real $ not research with grants?.
I'm not aware of CCE having lic any patents to anyone else? So no other company has needed all their developments and IP?
I can see that CCE have tried so many options and with other competing technology maturing quicker at lower costs and lower implementation risk eating parts of their market they were targeting. They have kept having to reinvent everything on different scales hoping to hit a sweet spot of cost, implementation , maintenance etc and at every turn it has become more complex and having to invent components( tethers, connections , controls etc ) rather than use off the shelf or modified inventory. Meanwhile things like linear generator components are maturing at cheaper price-points and greater efficiency and probably not considered in CCE initial model development .
Honestly if CCE had a outstanding model which showed economic output at economic cost and were partnered with a reputable company in energy it is still a high risk for anyone private or government to implement especially to do so on a large scale. Just talk to any engineer or financier who has been involved in scale up cycles of any industrial product. Left field things just keep hitting you and delaying the end product and subsequent $ it could be earning.
