Transport Vehicles (Producer-Gas) Sir S. Reed asked the Secretary for Mines how many transport vehicles have been converted from the use of petroleum products to producer-gas; and what steps are being taken to quicken the process? Mr. Lloyd I regret that exact figures are not available, but at least 125 vehicles are now running. According to figures recently supplied by the manufacturers of producer equipment, however, some 750 producer-plants for transport vehicles have been constructed or are in course of construction. As regards the last part of the Question, I would refer my hon. Friend to the reply I gave on this subject on 20th March to the right hon. Member for Limehouse (Mr. Attlee).
