Lower Temp operating FC systems may happen and even robotic AI FCs that can repair themselves.
I agree FCs are not cost-effective right now, unless they are only viable way to address living in an inversion atmospheric environmental sink situation.
We just may need them in our future, for energy usage . . . thus we have to do some development of them to see what they can do for us.
Wonder what FCEL is going to do for that type of costly FC R&D? Who is going to partner with us to make that happen? Has anyone info on that . . . as rising I rates leads to reduced options therein for funding Long Range Innovation needs. That's why FCEL must be going into owning FC Farms (to fold all the costs there-of into its accounting}.
