ABSTRACT
If any research I have done is remembered in the next century, it will be my work on the transport of heat across strong magnetic fields. This has enabled me to understand the curious behaviour of tokamaks, but, much more importantly, it has allowed me to tackle some of the outstanding problems in solar physics as I shall describe in my final chapter. So far as tokamaks are concerned, I fear that this knowledge will be of no consequence for the future; to quote the subheading of an article in the journal Science (volume 274, 6 December, 1996):
The $10 billion International Thermonuclear Experimental Reactor project is meant to show that fusion is a practical energy source. But a new set of calculations says that ITER (International Thermonuclear Experimental Reactor) will fizzle.
