STWA, Inc. Featured in 'Oil & Gas Agenda' Magazine

SANTA BARBARA, CA--(Marketwire - May 10, 2011) - STWA, Inc. (OTCBB: ZERO) ("STWA" or the "Company"), an innovative company creating technology focused on energy efficiency of large-scale energy production and improved fuel economy for diesel fleets, announced today that its fuel efficient technology has been featured in an article by U.K-based trade magazine 'Oil & Gas Agenda.'

The article discusses the development of STWA's products and technology for oil viscosity reduction that could lead to cheaper oil and greater fuel efficiency for engines using fuel oils like diesel, resulting in reduced emissions. The article profiles the Company's two products based on this technology: Applied Oil Technology (AOT™) for oil pipelines and ELEKTRA™ for improved diesel engine efficiency. AOT™ has already been proven in laboratory tests to reduce crude oil's viscosity and a full scale prototype of an AOT™ device is entering Phase II testing at the U.S. Department of Energy Rocky Mountain Oilfield Testing Center (RMOTC) in Casper, Wyoming.

"This is an exciting time in the evolution of our Company," commented Mr. Cecil Bond Kyte, Chairman and CEO of STWA, Inc. "Oil & Agenda's profile of our technology to improve the efficacy of crude oil transportation and our field-scale testing of a product prototype of our Applied Oil Technology (AOT™) currently taking place on a live oil pipeline that can simulate the harshest conditions is reaching key decision makers in our industry. We would like to thank them for their interview as we continue to work very closely with industry players in bringing our oil viscosity reduction technology to market."
