Gravity aided Catchment tank?

[tada]

My idea for the form of alternative energy called gravity is if you had a shipping container supposedly stromg enough to stack 10 other containers on it and the corners are where the strength is. So what if you put a flat low boy chemtainer on the back end of the container to store gravity fed water. Haven't worked out other issues like water pressure and gutter level- so gotta check out the hydro ram!! But especially if Big Brother going approve?? Any opinions even Nate??

Others want to make friends- I just want to make money.
