Those are appropriate ideas, and should be workable.  Rapid cooldown would
still be required, but might still lie within the range of affordability of
standard neuro option.  On a longer range basis, with economies of scale, it
does make sense that storage at minus 130 would be feasible without increased
cost (since the only fundamental difference is a lesser energy cost for the
storage at minus 130).  I agree that there are many (including myself) who are
presently committed to the lower cost neuro option, and that this intermediate
level needs to be developed in parallel with the implementation of the higher
cost approach.

Thanks, Mike, for making those observations.
