PanNew York Times Book ReviewTurrell would have been well qualified to judge the prospects of these different fusion technologies, but he withholds his opinion, except for expressing mild skepticism about the most audacious claims ... I generally agree with Turrell that nuclear fusion could be an incredible solution to our energy problems and is worth the investment. We understand the physical principles that would make it possible — the problem is one of engineering. I disagree with him, though, on the reasons the engineering bit is taking so long, and when we can expect the problem to be solved ... I came away from this book more pessimistic about the prospects of nuclear fusion than I was before ... The field suffers from hype, obfuscation, empty promises and well-meaning enthusiasts like Turrell who uncritically report what those with vested interests say. What nuclear fusion most needs is a reality check. This book isn’t it.
