Aiden, there is no resolution if you do not understand that there is
an optimum match for turbine and blades. Perhaps you need to ask
Hasbeen about this I am sure he will know more about that subject
due to his wide experience in the marine field.

At least we have now resolved why we cannot agree.
Good Night !

Mr 0,
What you're that ignorant about what engineers do, this really doesn't surprise me.

Bazz,
Again you'e basing you post on mistaken assumptions. There is indeed an optimum match... but it's a contextual economic optimum not a physical optimum.

Aidan,

I have a degree in engineering and have worked in the industry for my entire working life so I think that qualifies me to recognise engineers as tradesmen.

I think the community in general recognises engineers as tradesmen.

"Engineer' is a very broad term and should not be restricted to only those tradesmen who have earned a degree in engineering.

My TV repairman is just as much an electronics engineer as a graduate in TV engineer.

And my mechanic is just as much a mechanical engineer as the guy who designed the car.

'Engineer' is a relative term not an absolute term.

I regard myself as a tradesman albeit I have a degree in engineering.

Mr O refrain from talking about your credentials, and prove you have them by demonstrating the science of Wind and solar.

Myself I believe in ocean current and tidal flow power generation, it is more reliable than sun and wind.

pseudo-Josephus,

I only mentioned it because Aidan wrote

"Mr 0,

in response to my reference that engineers are tradesmen.

If he doesn't like it that engineers are tradesmen then tough bananas!

Mr 0,
The fact that you think engineers are tradesmen makes me suspect you are lying about having an engineering degree. Unless maybe you also think doctors and lawyers are tradesmen?

If, as you say, the community in general recognises engineers as tradesmen, it's because the community in general doesn't realise what engineering involves. Unfortunately many people get misled because of the similarity with the word "engine".

Your TV repairman (if he exists) may be a technical engineer (it's far easier to become one of those than a professional engineer) and I suppose you could call him an electronics engineer, but he's not an electronic engineer - that has a specific meaning. As indeed does "mechanical engineer" and that doesn't include your mechanic!

If you don't like it, perhaps you'd care to suggest some alternative terms to distinguish the guy who designed the car from someone who just fixes it?
