Yes places like this with a lot of rotting wood usually have a musty smell of damp, rotting wood. It usually isn't very powerful except in basements. I don't think it's a bad smell, but perhaps I just have a positive association with it...
Those are pretty wild looking ruins there in Kabul; there's also a neat tank graveyard there. I'll mark it all down, who knows what the future will hold.
I'm not sure if this is the real reason they're open, but I think that if a building is sealed in too tightly it can become overrun with mold in the summer months, leading to more rot and intoxicating the air. I've seen preserved buildings with air vents (or even fans) installed in the boarded up windows to ventilate the structure.
Hm, tough to find a comparative image. I think my head reached the top of the words stamped into the housing. Here's a similar looking one with a human scale reference: http://spiff.rit.edu/c...agara/niagara_2a.gif
The one in the illustration might be a bit larger than the ones in this plant though.
If the bottom hatches are open, I don't think it would float even if the water rose that much.
Also (on an interesting note), if there was extra flow it might get used by the other stations; there are a few other hydroelectric intakes upriver, which draw in as much water as possible to produce maximum power. They are able to take in so much water that the falls are visually impacted - so a treaty was agreed upon to keep a minimum of 50,000 cubic feet per second flowing at the falls for tourism purposes.
The water flow is kept at the minimum during the winter months, and every night in the summer. The stations reduce intake on summer days solely for tourism, letting 100,000 cubic feet of water to flow over the falls. The water below the falls fluctuates 3 feet during each transition.
Hi blackjack, unfortunately I do not have this newspaper clipping and so I can only glean whatever information I can get access to when researching the histories of these places. As we all know the newspapers don't always print the whole truth. I have updated the page in question, and hope it will suffice. Thank you.
