§ Mr. Albuasked the Minister of Fuel and Power what estimates have been made of the overall capital cost per megawatt installed of work and plant for the generation of electricity by underground gasification of coal, and of the cost per unit so generated.
§ Mr. Aubrey JonesThe only cost estimates that can be made at this stage are based on small-scale experimental systems of which the largest produced gas sufficient to generate 300 KW continuously for some months, and while these estimates encourage the hope that underground gasification could be exploited economically, they are based on a number of assumptions the validity of which it has not yet been possible to test.
