It is true that all these nuclear power applications have an evangelist and a prophet. Power production has many of the characteristics of a religion with all the same intensity, beliefs, uncompromising tenets of faith, desire to convert the non believers or if not successful, to belittle and discredit them. Each of these energy religions is out to save the world. This world saving must be done is a certain way to conform to the tenets and beliefs of the particular faith. I am not religious in this regard.
Energy systems are just tools that conform to economic political and economic reality. No energy system is perfect and they all are subject to faults and tradeoffs. There are no silver bullets.
True to the Voltaire quote – The perfect is the enemy of the good; The FF system could have already been deployed, but FF is waiting for aneutronic fusion and direct energy conversion to be perfected.
Neutronic fusion with the current state of the art heat conversion turboelectric technology could have already been in the market place as the low cost solution; not perfect but still very good. Yes, FF can do a very good job producing energy today. It could be far better than the Light Water Reactor or the Sodium Fast Reactor or ITER and LIFE or wind mills and solar panels. So why not get it into the market place?
