Energy plans

Postby olivier » Mon Sep 22, 2008 4:36 pm

FWIW, I have just discovered and started reading a book (a draft actually) entitled by David J.C. MacKay, Professor of Natural Philosophy in the Department of Physics at the University of Cambridge.
Everything is presented from a British perspective, however much of the reasoning, if not all the figures, remains valid for other countries.
It is too early for me to develop an opinion on the book, but I am interested in the global approach : (i) build a set of renewable "energy plans that add up" based on "numbers, not adjectives" then (ii) see what each plan looks like and implies in the real world.
What is more, this book is an interesting collection of data and links.
Fusion is considered under the tokamak approach which, in the most optimistic hypothesis, would come too late to be taken into account in the study.

Yes, David MacKay gave a talk about energy in Culham. He has done an amazing amount of research on it.

Regarding fusion coming too late, the same might well be said for the Polywell approach, while I would reject it out right, if a functioning Polywell reactor is built in 5 years as Bussard said I would be astounded.

jmc:

If p-B11 works, 5 years isn't unrealistic. The engineering on these systems isn't all that bad. Getting away from D-T makes it a lot easier.

n*kBolt*Te = B**2/(2*mu0) and B^.25 loss scaling? Or not so much? Hopefully we'll know soon...
