It is not necessarily true that expensive experiments are not worthwhile doing but there are plenty of rather cheap experiments which are certainly worth doing.

American science is much more organized, much more hierarchical than British science has been.

It doesn't matter whether you can or cannot achieve high temperature superconductivity or fuel cells, they will always be on the list because if you could achieve them they would be extremely valuable.

I don't suppose I'll ever retire completely.

Usually, if you have a new idea, you very rarely break through to anything like recognizable development or implementation of that idea the first time around - it takes two or three goes for the research community to return to the topic.

I think British science is becoming more like American science - and then there is everybody else, I'm afraid.

Now, of course, cold fusion is the daddy of them all in a way, in terms of value, so I think that viewed in a social way, from the point of social considerations and economics, it will tell you that this thing will stay around.
