The generators at Niagara Falls, Ontario are quite impressive. The first 
plant was designed by Nikola Tesla and was very famous as it was "The 
first great victory of Tesla's Alternating Current Electricity over 
Thomas Edison's Direct Current." Being near them is almost frightening 
just from the sheer size of the machinery and noise of 1200 cubic meters 
(over 42,000 cubic feet) per second of water driving it all. As this is 
providing 1/4 of all power used in the Province of  Ontario and New York 
State, backup systems for everything are integral to the design.

I hope they don't use Windows :)
