§ 32. Mr. Cecil Wilsonasked the Minister of Fuel and Power what progress has been made in the production of petrol and/or other fuel from mines refuse or town sewage?
§ Mr. T. SmithI am glad to say that progress is being made with the use of methane in road vehicles as an alternative to petrol. Some local authorities, whose sewage digestion plant yields a surplus of this gas, are already using it in their vehicles. Certain others are exploring, at the request of my Noble Friend the Minister of War Transport, the possibility of installing the necessary equipment, which can now be made available. Some interesting experiments in the liquefaction of methane are taking place at one colliery, but I am unable to report any other developments in the production of petrol from mines refuse.
