Recent books have raised the public consciousness about the dangers of global warming and climate change. This book is intended to convey the message that there is a solution. The solution is the rapid development of hydrogen fusion energy. This energy source is inexhaustible and, although achieving fusion energy is difficult, the progress made in the past two decades has been remarkable. The physics issues are now understood well enough that serious engineering can begin.The book starts with a summary of climate change and energy sources, trying to give a concise, clear, impartial picture of the facts, separate from conjecture and sensationalism. Controlled fusion -- the difficult problems and ingenious solutions -- is then explained using many new concepts.The bottom line -- what has yet to be done, how long it will take, and how much it will cost -- may surprise you.
Francis F. Chen's career in plasma has extended over five decades. His textbook Introduction to Plasma Physics has been used worldwide continuously since 1974. He is the only physicist who has published significantly in both experiment and theory and on both magnetic fusion and laser fusion. As an outdoorsman and runner, he is deeply concerned about the environment. Currently he enjoys bird photography and is a member of the Audubon Society.
Rezensionen / Stimmen
From the reviews:
"The 'indispensable truth' is that Chen . has written what may well be recognized as the definitive retrospective on the promise of endless supplies of cheap, clean nuclear energy from fusion, offering the prospect of realizing the promise at last. . It is stylishly written, designed, and illustrated to appeal to general readers . . Chen is in his comfort zone as he tells his story, and the indispensable truth is that it is just that-indispensable! Summing Up: Highly recommended. All levels/libraries." (L. W. Fine, Choice, Vol. 49 (3), November 2011)
"With An Indispensable Truth: How Fusion Power Can Save the Planet, Frank Chen has provided a sweeping perspective on fusion energy. He covers everything from climage change to plasma instabilities. On climate change and energy, the view is best from 30 000 feet: The book provides a good high-level overview of the issues at stake...On fusion plasma physics, Chen's area of expertise, An Indispensable Truth provides an intuitive, up-close explanation of exciting recent advances and future challenges...An Indispensable Truth provides an exciting whirlwind tour of energy issues and technologies, with particular insight into fusion. Chen is correct to emphasize the tremendous progress that has been made in fusion research. ITER will produce hundreds of millions of watts of thermal energy from fusion, for periods of up to an hours. However, it remains for the world, and in particular the US, to decide if we will develop fusion into a practical energy source. We will need it." (Physics Today, Volume 65, Issue 2, February 2012)
