§ 20. Mr. Hastingsasked the Minister of Fuel and Power what experiments have been made by his research officers in the use of methane gas derived from sewage purification for heating or lighting in England and Wales; and to what extent such experiments have proved successful.
§ Mr. Geoffrey LloydSuch uses of methane gas are already well known, but the collection of the gas appears to be an economic proposition only in works dealing with populations of 50,000 people or more.
§ Mr. HastingsHave not some of the results been very discordant? Would not the right hon. Gentleman think it perhaps right to have an inquiry on this subject, or at least to issue a memorandum, as its importance seems to be increasing?
