You can use any tanks/drums with pipes and faucets the same way the smeltery works.
Portable tanks can even be set to output into the basin directly, if you put the basin under it.

Neither had particularly dangerous jungles, though.

Other cities will be more difficult, and they have other stuff you'll need.
If you still haven't figured it out, it's called Waila. Check your controls to see which button toggles "[Waila] Show/Hide", which is probably what you pressed.
I haven't tried this yet, but I have played with tornados in the past (Atonement modpack). Are you sure you want to go with it? It makes things impossible to build on the surface, and the areas around you become a crappy wasteland pretty fast.
