 It's
a Turbine Runner!
Here's what
the explanatory sign days:
"HOOVER
DAM TURBINE RUNNER
"This
cast iron turbine runner (water wheel) which is 14.2 feet in diameter
and weighs over 34 tons, powered the N-7 generator at Hoover Dam Power
Plant from 1944 to 1982. The function of a turbine runner is to convert
the force of filling water, delivered through the penstock pipes, to rotating
energy which is then utilized by the generator in producing hydroelectric
energy.
"This
turbine runner was presented to the Boulder City Museum and Historical
Association on April 30, 1983, by the Bureau of Reclamation, U.S. Department
of the Interior."

Thanks go
to Mark Holloway of Beatty, Nevada,
for photographing the turbine runner in Boulder City, Nevada, and coming
up with the bogus mutiple choice answers.
