Where are all the nuclear fusion power plants?

In the late 1960’s it was predicted that within 20 years we would have commercial fusion reactors, generating power that was so cheap it would almost be given away. Today, some 55 years later, there is still no commercial power plant using nuclear fusion. But are things about to change?

After reminding ourselves about the basic physics of the fission and fusion processes, David will look at the technological approaches that have been followed in an attempt to generate power from the fusion of atoms. 

Over the intervening decades a lot of research has taken place around the world, so he will review that before looking at the approaches now being followed by private ventures.Finally, David will get out his crystal ball and look to see how the road to fusion power might develop.

This talk was prepared for and given to the Retired Engineers Association in Worthing in October last year.
