Mr. Watkinsasked the Minister of Fuel and Power what applications he has received for allocation of foreign currency for the purchase of butane-air plants as an alternative to gas manufacture in Wales; what reports he has received from the officers of his research department on the success of this development; and what further experiments with this supply he intends conducting in the rural parts of Wales.
§ Mr. Geoffrey LloydThe Wales Gas Board have received licences to import three such plants from the United States and have also imported one plant from France under open general licence. I understand that the plants have so far proved satisfactory. The Board are now considering the installation of additional plants and are experimenting with the use of propane in place of butane.
