<p>Greetings all,</p>
<p> I bought that book when it first came out and still have it. At
the time it was estimated that controlled fusion was 30 years
away. That 30 year time line hasn't changed. </p>
<p>From my perspective, we will never achieve controlled fusion as a
sustainable and economically viable alternative to carbon
recycling. Controlled fusion is a pipe dream and a waste of time
and resources.</p>
<p>The only theoretical possibility is a Dyson sphere, which is well
beyond our capability. Besides, a Dyson Sphere is catastrophically
unstable, the gravitational effects of other plants would tear the
structure apart. </p>
