Wave bye bye to expensive barrage plan

The letter from Martin Hook brings a note of common sense into the Severn tidal power discussion.

The debate seems fixated by the prospect of a barrage mega-project with the inevitable risks of escalating costs and drawn-out timescales.

I don't see how the drastic impact on such an important estuary environment could be considered acceptable.

Surely we should instead be putting our resources into fleets of individual floating or submerged turbines anchored to the seabed, converting the kinetic energy of the tidal flows into electricity with minimal infrastructure and minimal effects on the environment?

Unlike a vast barrage, the payback (both financial and in terms of CO2 saving) could start quite soon, the technology would evolve in cost-effectiveness in the light of experience.

A wide variety of suitable locations could be found which would feed into the National Grid closer to where the demand is.
