Arizona

What did your area look like 1,000 years ago? Well, people in the year 3023 might have the luxury of finding out, thanks to an art/science project called the Millennium Camera, which will take an extremely long-exposure photo of the Arizona desert.

With most of Arizona in a state of moderate to extreme drought, the Gila River Indian Community and the US Army Corps of Engineers have signed a deal to begin a solar-over-canal project designed to cut down evaporation and boost solar efficiency.

The US Department of Energy has committed US$20 million to an Arizona-based project that will use nuclear energy to create green hydrogen, testing its capability as a liquid backup battery and as a secondary product for nuclear power installations.

I've often wondered what it would actually be like to have a small footprint, off-grid house. How does it work? What does it take? How much does it really cost? Does it feel like going back in time?

As Waymo’s self-driving vehicles continue to clock up the miles, the company is focusing its trips based on feedback from the first year of its early riders program in Phoenix, Arizona. As well as expanding existing partnerships, Waymo has now teamed up with Walmart and DDR to streamline shopping.

Although there are trillions of liters of water floating around in the air, it’s not easily accessible. Now engineers have developed a device powered by the Sun that can pluck practical quantities of drinkable water out of thin air, and they've successfully field-tested it in the Arizona desert.

Occasionally asteroids will get caught in a gravitational dance with our planet for a few years, and last year astronomers discovered one of the most stable of these “quasi-satellites”. Now they’ve peered closer to get a better understanding of what it is and where it might have come from.

​​One problem with teaching robots to walk over uneven terrain is that what works in one setting may not fly in another. One solution would be to have the robot teach itself as it goes, which is exactly the approach researchers at Arizona State University have taken with their so-called C-Turtle.

As self-driving cars edge closer, manufacturers are expanding the range of scenarios they face during testing. Waymo is now opening its cars up to the public in Phoenix, AZ, in an attempt to see how they handle the cut-and-thrust of daily family duties.

​​An international team of researchers has calculated the cataclysmic conditions created when an asteroid struck northern Arizona roughly 49,000 years ago by analyzing the structure of microscopic diamonds known as zircons.

A new landmark observation tower designed by Danish Architectural firm BIG is to be built in Phoenix, Arizona.

Fluor Corporation has announced plans to build a 125 MW photovoltaic solar power plant in Maricopa County, Arizona by the end of 2013.
