"This is going to be a tremendous boost not just to Tucson but to the whole state of Arizona," said AzRISE co-director Joe Simmons, who is also head of the UA materials science and engineering department. AzRISE, launched last summer, will find ways to make solar energy cheaper - and more attractive to consumers, he said. Electricity produced by photovoltaic solar panels remains more costly than power from conventional coal- and gas-fired power plants, he said. Arizona's extensive sunshine makes it a natural for exploiting clean solar energy, he said. "The promise is fantastic.We just have to get the economics down," Simmons said."We can improve efficiency and reduce costs with new techniques for processing the materials for making solar devices. "Our goal is to increase solar efficiency by two and reduce the price by two," Simmons said."Then everyone would adopt it in a minute, and the planet would benefit." Creating a center for excellence such as AzRISE will leverage solar expertise from UA and other areas to move solar ahead, he said. "We have a lot of intellectual capital at UA.There are a lot of ideas kicking around at the university," he said.About 60 UA faculty members have expressed interest in working on AzRISE solar-related programs. Fostering collaboration among UA researchers and others from around the state could see Arizona - long touted as boasting huge solar resources - approach its solar potential, he said. "Solar energy has been talked about for an eternity.To make a really big impact in the state, we're going to need to use all the intellectual capital in all the state," he said.

One project under consideration involves developing plans for a concentrating solar facility that would use the sun's energy to produce electricity and remove salt from seawater making it safe for drinking, Simmons said. The project would use shiny parabolic troughs to heat water in a system of tubes. The heat distills the salt out of the water, and the hot water is used to run turbines that produce electricity, he said. Such a plant in the Gulf of Mexico could supply Arizona and Mexico with clean power and clean water, he said. He said he expects a scale engineering model of the system could be ready to test in two years and a commercial plant could be operational in five years, pending funding of an estimated $10 million to $20 million. "Since desalination is a big issue worldwide we think there is a good chance of finding investment to push the research," he said.
