It has been suggested at various times that I should start an operation in the United Kingdom but - bearing in mind my age and medical history - I think this would be not a very sensible way to go forward.

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.

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

At the moment I am taking a very careful look at some of the work which we have done in the past.

I am a caricature of what British science is about in the way I work.

I don't know whether you have done your calculations but, about two or three years back, I did a first assessment of what the first successful device would be worth and it came out at about 300 trillion dollars.
