    I read about Solid State Transformers <a href="https:&#x2F;&#x2F;www.powermag.com&#x2F;the-solid-state-shift-reinventing-the-transformer-for-modern-grids&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.powermag.com&#x2F;the-solid-state-shift-reinventing-t... with some interest. However they have some weird failure modes. At least large chunks of metal twisted around large chunks of a different metal are predictable and don&#x27;t need firmware updates.

      Solid state transformers are a misnomer: Traditional transformers are already solid state - no moving parts. And SSTs do the actual voltage &#x2F; current transformation using a smaller, higher frequency traditional transformer. A more appropriate name for SSTs would be high frequency transformers or IF (intermediate frequency) transformers or something.

        Ironically, &quot;solid-state drive&quot; was also misleading, because &quot;solid-state&quot; was an industry marketing term to differentiate anything using exclusively semiconductors from any older technologies, such as vacuum tubes. So a standard HDD, based entirely on semiconductors and not vacuum tubes, would indeed be &quot;solid-state&quot; by those standards, but I for one understood a &quot;solid-state drive&quot; to be differentiated by no moving parts. Vacuum tubes did not, per se, move a lot. Not like an HDD platter or head.

        Also regarding child comment, how did we already get to slurs for those with developmental disabilities? Can we avoid those, please?

          I assumed it was a typo and they were actually referring to &quot;cretons&quot;, a type of French-Canadian potted pork.
