One of my theme songs is that if you can't do it in a test tube, don't do it.

The problem is that replacement of Quantum Mechanics by Quantum Field Theory is still very demanding.

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.

If it had been anything else, we would have said, 'People don't want us to do it. Forget it. Let's just leave it alone.' But this is not in that category. This is interesting science. New science. With a hint of a possibility of a very useful technology. Therefore, if you've got any integrity, you don't give up. You only give up if you find you are wrong. But as long as you believe that you are right, you have to continue. And you have to take the consequences.

You see, I am a very conventional scientist, really.
