The documents in File SZ/MFP/3 focus largely on coal resources, including gasification and the production of synthetic oil from coal. They also address the problem of peak-loading of electricity and gas supplies, the potential for exploiting other forms of energy generation, and effective energy conservation. There are papers on: tidal and wind power; solar energy; gasification of coal at source (i.e. underground); the use of diesel oil instead of petrol for agricultural machinery; peat-fuelled gas turbines; methane; heat pumps; insulating materials; and flame radiation. This file also includes a copy of the interim report of the Ministry of Housing and Local Government Committee on Air Pollution, HMSO, December 1953, Cmd 9011.
The documents for 1954 are for the greater part reports and papers on atmospheric pollution from sulphur and means of recovering sulphur from flue-gases. Sulphur and sulphur recovery also feature in the correspondence in File SZ/MFP/2. This was also an area of interest to the NRTC, from the point of view of exploiting indigenous sources of sulphur for industry (to which Series SZ/NRTC refers).
