Barrages of a use

Letters

Your correspondent's references to tidal power barrages (NCE 22 January) recall previous investigations.

Apart from the Severn, other locations include the Mersey, Morecombe Bay, Solway Firth and Strangford Lough. Perhaps all these and other sites should be re-examined as alternatives to wind power.

Another source of power that should be implemented is the thermal recycling of municipal and industrial wastes, including bio-mass, by pyrolysis. This would reduce the use of landfill sites and avoid the tax that is a significant contributor to council tax bills.

The gasification of all waste should be investigated as a separate energy source.

'Quarrying' existing landfill sites as a 'feedstock' for gasification may be a possibility.
