STWA's Elektra™ Technology Exhibits Repeatable Fuel Savings in Preliminary Laboratory Testing

SANTA BARBARA, CA--(Marketwire - Oct 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, today announced that a preliminary prototype of its ELEKTRA™ technology for improved diesel engine efficiency has shown repeated fuel savings of approximately 4.1% in laboratory testing. The Company's technology will be undergoing additional testing and improvements with its co-development partner, Verdantec Technologies. This testing process will be conducted concurrently with the testing of Applied Oil Technology (AOT™).

STWA's ELEKTRA™ technology improves diesel fuel economy in both land and marine diesel engines. The Company's preliminary experimental prototypes have shown repeatable improvements in fuel economy of approximately 4.1%. Additional research is being conducted at this time under controlled conditions at the Company's research facility in Morgan Hill, CA, to optimize the results above 4.1% and further support ELEKTRA's commercial proof of concept for improved fuel economy and reduced emissions in diesel engines.

"We are very excited by these preliminary results from initial testing with Verdantec Technologies, our co-development testing partner," stated Mr. Cecil Bond Kyte, Chairman and CEO of STWA, Inc. "As the global demand for diesel fuel continues to grow, our market research for this technology is indicating that the diesel engine on-highway market alone is substantial, with over four million tractor-trailers on the road in the U.S., with Off-Highway, Marine and Construction Equipment presenting an even greater opportunity. With additional refinements and research we aim to further improve our technology to properly begin addressing these market opportunities."

Mr. Kyte added, "Over the last year and a half, STWA and Verdantec's relationship has continued to grow. Our collaborative efforts and support for ELEKTRA™ has been mutually beneficial, with Verdantec's involvement offsetting 50% of our operating costs at the Morgan Hill Facility. Verdantec has proven itself to be an excellent team player with a complementary suite of products and platform technologies. We are excited by the results we have achieved from a preliminary ELEKTRA™ prototype, and believe that optimizing and refining our model could lead to significant increases in our baseline results and increased performance in not only diesel trucks, but other categories including cargo ships, which burn bunker fuel, a less refined, much heavier form of fuel."

Mr. Greg Spak, President of Verdantec Technologies, stated, "Collectively, our two companies offer a suite of products that will realize fuel savings exceeding 20% for diesel trucks. Together, this represents a significant package savings for the commercial fleet operator. We are excited to move forward with further testing of ELEKTRA™ as we have already seen proven, measurable results earlier this year."
