But yes, the 'invention' is surely pseudo-science. Even if salt does boil, I am sure it will solidify soon and not go much up. BTW, wood (burnt in chulhas every day in tonnes of quantities) has NaCl. Also, seed particles have to be of specific size to precipitate rain drops. But yes, the inventor did have scientific mind and mentioned that we need to use radio-isotopes of NaCl measure if it goes up. Also, he presented all the data, recognized that the sample was small and accepted that he did not conduct any case-control style studies. The organizers kept his talk at the end of morning session, I think to provide comic relief. http://www.calrecycle.ca.gov/LEA/Advisories/46/

Common salt has extremely high vaporization temperature of over 1400 degrees (C), whereas the tyres have an ignition point of around 300. Although I haven't tried it, I'm sure the salt would just remain as a residue. However, certain other low-vaporizing minerals in the tyre MAY cause the rain.
