Interesting, doesn't say much about the patented corrosion prevention that would enable the storage of the molten sodium hydroxide.

- pfdietz 5y agoMolten NaOH will oxidize many metals, including nickel and iron, so maybe cathodic protection? Yes, that's what it looks like: https://www.freepatentsonline.com/y2020/0105424.html https://www.freepatentsonline.com/y2020/0105424.html
- oconnore 5y agoIt seems unfortunate that it's possible to patent something so well documented: https://en.wikipedia.org/wiki/Cathodic_protection https://en.wikipedia.org/wiki/Cathodic_protection https://en.wikipedia.org/wiki/Galvanic_anode https://en.wikipedia.org/wiki/Galvanic_anode
- CameronNemo 5y agoIsn't the point that a patented process is documented as part of the patent application? Industrial processes and materials seem like a great use of patents from my POV. Psychology and biology I'm more concerned with.
- mensetmanusman 5y agoIt’s a well documented problem that many groups have tried various technical approaches to mitigate over 100,000 hour operating windows. It’s not too surprising that a particular implementation that has various benefits compared to the existing state of the art would be patentable.
- mcdonje 5y agoWell it says that's the company's core IP, so...
- s0rce 5y agoPresumably the fundamentals are patented and not a trade secret. I could see parts of the manufacturing process being a trade secret.
