While $3.35 or 3.2¢ is quite high it should continue to fall as technology improves. And for FF we still need to see it in action to know all the actual costs. Of course I agree that currently the margin seems to be pretty high.
One thing what I am concerned about FF in comparison to renewable energy sources is that it makes military technology cheaper and more advanced. I just hope this will not lead to more rounds of cold war, so that all the economical advantages would be negated as result.
