asked the Minister of Housing and Local Government what record he has in his Department of devices which their inventors claim can mitigate the nuisance and danger of smoke pollution; whether consideration has been given to the apparatus, of which particulars have been sent him; and if he will consider the offering of a competitive reward for inventions capable of domestic adoption for this purpose.
All the suggestions my right hon. Friend receives are carefully examined by the appropriate experts. I will have the one about which the hon. Member wrote to my right hon. Friend the Minister of Health examined, and I will write to him. A great many suggestions are received, and my right hon. Friend does not think that it would be useful to offer a competitive reward for more.
