&gt; It&#x27;s not even been developed, yet the author is convinced it will be &#x27;the most expensive way to create electricity ever devised&#x27;.<p>Sounds to me like the author is right in a sense. A lot of money has been going into fusion for many, many years now. If you look at the bottom line you&#x27;re going to need to be generating a LOT of electricity from fusion before you&#x27;re ever going to break even.<p>I&#x27;m not saying that this is the right way of looking at it, financial gains aren&#x27;t everything, after all. But fusion IS very expensive electricity.
