I would also wonder if Titium is that expensive... and it generates titium... would that be part of the "break even" equation? Creating something rare to sell?
It is so rare because tritium is not found in nature in any significant quantity. The amount on the market comes from water recovered from water pools used for spent nuclear material storage.
There also is no enormous market for tritium.
So in short, fusion reactors exist on both sides of the tritium market, by becoming the primary producers and consumers of it, which should lead to significant drop in price of tritium.
Current demand is a couple hundred grams per year. We just don't need that much of it. The cost per gram would go down a lot if we needed to mass-produce it.
I think what I'm alluding to is, how much can the cost go down. In the case of fossil fuels there value is strongly based on their physical scarcity and cost of extraction/delivery etc.
How much do these things ring true in this case and what are ideas of improvement?
