My Lords, I am grateful to the noble Baroness for those comments. What they serve to do is illustrate quite how closed the department is to this technology. If it was true that there was a saving of only £2 on an investment of £300, no one in their right mind would develop, manufacture and install it, and yet we have an industry that is doing so. Not only that, it is a British industry which is manufacturing in the UK.
I am grateful to the noble Lord, Lord Deben, for his intervention to say that small things which add up may not generate headlines, but actually they can generate headlines when it is a British-based industry creating British jobs and which can go on to export its technology around the world, leading to a positive
balance of trade. Each individual bit of technology may not make the headlines, but the investment in UK skills, infrastructure and jobs should do so. Obviously the technical issues that have been quoted will, I am sure, be contested by the industry. All I am asking is that the department should not start out with a negative predisposition, it should look at the evidence in the round and listen to the industry.
