In January of this year, at a meeting of the Engineers Club of Sun City, Arizona. A.P.S. ( the local power company) gave a presentation in which they explained their plans to build such a plant south of Phoenix, below Gila Bend. They were very upbeat about it’s possibilities. Maybe there is light at the end of the tunnel!
Take a look at this video and pay particular attention to the very last statement made by the spokesman.

This has real possibilities! But whose backyard do we build the plant in?
