Men can do the 'almost impossible' with the means available and enough men and mules.
Lake Titicaca (I still giggle when saying that) is over 2 miles above sea level in Peru. The ship restoration, described in the above link has been an ongoing project for several years. It's original steam plant was removed and replaced with an oil engine. She's up and running now and is one of the nicest examples of 'antique iron' restoration in South America.
That boiler you show is a scotch marine type, return flue. The furnace section appears to have been chopped out from the jagged edges in the photo. The doors, with the builders name above, is actually the back of the boiler.
Richard, I didn't see that last picture (of the turbine) in the group of the hydro plant. That's a Francis type wheel. Interesting as it's a fabricated case instead of a cast iron housing. S Morgan Smith turbines, a company acquired by Allis Chalmers in York, PA built hundreds of Francis turbines. Many are either still in continuous use, or put back into service. The original Collins Axe factory, in Collinsville CT has several and one is operational, except that the state DPUC won't give them a permit to operate, or at least to operate and generate power.
