Hi,

On the accumulation (tank) it does not seem realistic to me, the tank will quickly empty.
It would be better (as was the case for the old mills) to opt for a type reserve pond

For more technical data, you have the essential forum French reference.

Then there is also the question of "water rights" which is not so simple : Mrgreen:

What a great idea. And it protects the seawall from the force of the waves. It's a win-win.

Edit: everywhere except on the French Riviera. There no waves, no current, no wind, too hot water. : Mrgreen:
So it's not recommended in paradise. : Mrgreen:
Maybe a little winter storm to try it out. : Mrgreen:
But everywhere else it must work well

I still wonder if this equipment can withstand a big storm ...

If it's to replace them every 5 years : roll:

The dikes are old and they hold up.
Not cons the old ones by dint of seeing them shatter.
You have to be as smart with fairly solid materials.
But as Janic would say it puts the maintenance technicians of the system in unemployment and worse still those who take care of the maintenance of the dam will go to pick up the plastics on the beach, it is humiliating.
So not too strong like that there is work to untwist everything and change the nuts and bolts and the "CGT dyke" is happy, they are doing nothing since they have taken care of a contract where they work if the dike breaks out.
Or install a breakwater, but it's a win-lose

Yes, but a mechanical system, with moving parts, is difficult to make as solid as a block of concrete (especially since the floats must be less dense than water : Mrgreen: ).

When I see the size of the tree trunks that arrive on the beaches after each storm : Shock:

The trunks cover everything.
But it is close to a big river and it floats with the game of currents. So it's still pretty much in the same area to be avoided.
These are extreme cases as if we are bent on putting a large wind turbine at the top of Mont Ventoux. Every 2 days you will pick up the blades in the Rhône 1700m below
