  • One thing folks don’t think about or understand is how critical PFAS polymers are for dairy, food, and pharma production. It is used extensively as there aren’t many suitable alternatives for gaskets, valve seals, pipe lining, instrument coatings, hoses, etc. Alternative materials don’t have the heat, chemical, or biological resistance to effectively work for all applications without introducing other toxic materials or inability to be cleaned and sanitized properly. Ban those materials and those industries will shut down in the EU unless consumer safety is compromised. Development of new materials will take years. We need to move away from PFAS, but it needs to be done in an orderly fashion.





  • What you said is correct except that they went into it ignoring the lessons of the past. NASA had done tons of testing and knew that the launch pad wouldn’t survive half the Starship’s thrust and designed a launch pad that worked. Space X instead chose to believe that a special concrete would be enough. The new launch pad is missing a flame diverter and will likely be the failure of the next vehicle. The iterative approach doesn’t work if you can’t get a launch clearance from the FAA due to a lack of trust.
