Slow motion


Regarding the Severn Barrage renewable energy scheme (Debate, NCE 11 January and letters, NCE last week), has the slow alternative been explored?

By setting out to construct the project over say 50 years:

Environmental impacts can be minimised, studied, debated and plans adjusted to suit.

Small axial-flow generation units can be embedded from day one to help finance progress and thus minimise financing costs.

Negative impacts on finances of Severn bridges are avoided.

The greatest legacy left to posterity.

So radical a change of outlook merely provides a latterday understanding of some realities of life. For instance, it has taken 50 years to build Heathrow Airport, 100 years to build the London Underground and 200 years to complete the Channel Tunnel.
