In my opinion, if we suceed in producing a prototype reactor, attempts to regulate it out of existence will be the main way the oil and gas companies fight this. The response will have to be political–educating ultimately millions of people about this technology and fighting to ensure that it is not regulated as fission is. FF can’t be used as a weapon, it is safe enough for urban location, etc. It will be a huge political battle and will encompass the whole question of the political power of oil and gas and their allies.
If FF is regulated the same way radioisotopes are, it will be fine. Remember, there are radioisotopes in every smoke detector, which are required in every US home.
