SIR – I read with interest about how to produce power more efficiently (T&A, April 3).

I remember seeing the gasometer on Canal Road about 25 years ago. I wrote a letter to the corporation about it asking if it could be used to generate gas from the grass clipped from road edges by the corporation workers mowing grass to keep the streets tidy in the estates.

About 60 years ago I read an article in Reader’s Digest about an abbey of monks somewhere who used grass, food waste etc, to produce gas from their holding tanks like the gasometers. They generated electricity for the abbey and cattle byres etc. The leftover grass residue was a super nutritious silage to use on their crops of wheat, oats etc, the straw from which went into the tanks to produce more fuel.

I don’t know if the gasometers are still in situation in Bradford, they were used to get a “smelly” agent into the gas before going to people’s gas meters.

Around small towns the farmers could give animal manure to gasometers and get back nutritious silage.

I hope someone in the future can use gasometers to produce power.
