&gt; <i>Can you comment on this story about Edward Teller?</i><p>It&#x27;s an anecdote of an anecdote. It&#x27;s literally third person hearsay, with Teller saying &quot;Oh, it &quot;might&quot; be possible&quot;. We don&#x27;t even know he said that. Even on the off-chance he did, it means practically nothing. There are similar wordings and phrasing done about breaking light speed from respected physicists. You could probably get one to say &quot;might&quot; as well. It doesn&#x27;t mean there&#x27;s any validity behind it. The point and facts still stand - you&#x27;re not going to break the Coulomb barrier at room temp. It&#x27;s an impossibility.
