F.A.R.T. Banks

And on the subject of lost waste, you know the way methane is an energy source, I believe that we should have F.A.R.T. Banks (Flatualent Air Retrevieval Tanks). Places where we can utilise our normaly wasted personal gases. We could even put a special on at the base of the spire which could fuel a giant flame out of the top. And nobody can argue with this one fact: we will have them created one of the most unique and remarkable tourist attractions the world, yes the world, has yet seen.
