Not value for money. At last, someone is beginning to see sense when it comes to the cost of renewables. or

(a) If you store water at the high tide level in a reservior, you can use ithat water for power at any time except high tide, but perhaps best between mid and low tide.

(b) If you empty a reserviour at low tide, you can fill it at any time to generate power - i.e. fill it from either (i) a full(er) reservior, or (ii) the sea when not at or near low tide (but perhaps best between mid and high tide).

This means with sufficient reserviour capacities, you should be able to generate power continuously.

A when are the gates opened and closed? At what point on the cycle is the power produced?

But we would have the advantage of having to join the Euro and losing our rebate and may have to pay more to ensure we aren't vetoed by Turkey if they join before us.

But even then its probably worth it.

How do you start a petition to rejoin the EU as soon as brexit has finished?

If you waited until high tide, there would be no flow since the water inside |& ouside will be the same.

So its three times the cost not what they have quoted.

Its three times the cost in maintenance not what they said.

Its three times the environmental damage too.

Its also three times less reliable.

It was you who suggested that.

"Far better to pay some other country to build our nuclear power stations, than develop a new technology here."

So have you become a Brexiteer, or are you still just another desperate remoaner

The opening and closing is, however, defined by the state of thentide.

Anyway you are thinking too small, all we need to do is build a dam all around Scotland and use it for pumped storage to store the energy generated by damming the Irish Sea.

What happens when the tide is the same height as the lagoon and you open a gate? How much power does it generate? How much does it generate when they are using the turbines as pumps to fill the lagoon so they can unleash it when rates are higher and they can make more cash?
