Photograph showing an aerial view of Hoover Dam, Lake Mead, the Colorado River, and the Mike O'Callaghan-Pat Tillman Memorial bridge under construction, Nevada-Arizona border, February 3, 2010

Date

2010-02-03

Description

Photographer's notes: "Evening aerial view of the dam and bridge. Twelve tub (box) girders spanned the central pier caps of the bridge forming part of the substructure for the roadbed. Note: This photo was taken well after sunset and was only possible because of the state of digital technology in 2010." Site Name: Mike O'Callaghan-Pat Tillman Memorial Bridge

Photograph of the final tub girder brought into position for the Mike O'Callaghan-Pat Tillman Memorial Bridge, Nevada-Arizona border, April 15, 2010

Date

2010-04-15

Description

Photographer's notes: "The final tub girder of the bridge's construction is brought into position, April 15, 2010. Note: I desired to switch my location for these final installation shots, but it would have been impossible to relocate to the top of another cliff in time to document the event. Nobody consults the photographer about the 'best time of day' to accomplish some tasks!" Site Name: Mike O'Callaghan-Pat Tillman Memorial Bridge

Aerial photo of the power block at the Crescent Dunes Solar concentrated solar power plant near Tonopah, Nevada: digital photograph

Date

2015-10-09

Description

Photographer's note: "Aerial photograph of the power block of the Crescent Dunes Solar concentrated solar power plant near Tonopah, Nevada, USA, includes a 540 foot (165 meter) concrete tower topped by a black solar receiver, two large tanks for molten salt storage (one "cooler" at approximately 550°F / 288°C and one hot at approximately 1050°F / 566°C), a steam turbine generator, and an air-cooled condenser. On this day, the system was being tested by heating molten salt at the top of the glowing tower to 1050°F (566°C), then using the resultant thermal energy to drive steam turbines, which in turn sent electrical power to the Nevada grid.."
