It's a rectangle prism. Just wont do....
What is wrong with the existing one?
Not enough photo-voltaics.
The current one, though it appears to be very solidly constructed of reinforced concrete, is too close to the street and vulnerable to vehicle-borne explosives, it seems to me.
But judging from this illustration, this appears as if it will be less solidly constructed and also vulnerable to street attack.
