Nuclear fusion on brink of being realised, say MIT scientists
Meta rant: I would like people to remind themselves that HN&#x27;s rules explicitly disallow shallow dismissals. Unfortunately this comment section seems to be nothing but.<p>The material science behind high temperature semiconductors has undergone radical changes in recent years. The techniques being used are largely well understood science and the downsides of previous approaches like ITER are explicitly avoided. There has been a visible explosion of commercial activity in recent years.<p>People bander around the &quot;always 20 years away&quot; moniker as if we should put <i>today&#x27;s</i> estimates on the same grounds as the guesses from those early 1970s projects that were never even properly funded. People were not screaming &quot;20 years more&quot; at the turn of the century.<p>You don&#x27;t get to discount something as potentially groundbreaking as this just because it&#x27;s taken a little while to get here. Either put up or shut up. I would <i>love</i> to hear genuine substantive conversations here, if people were willing to have them.
