SANTA BARBARA, CA--(Marketwire -04/09/12)- STWA, Inc. (OTC.BB: ZERO.OB - News) ("STWA" or the "Company"), a developer of energy efficiency technologies in the multi-billion dollar oil pipeline and diesel engine markets, announced today that the United States Department of Energy's (DOE) Rocky Mountain Oilfield Testing Center (RMOTC) has published the results of an oil pipeline efficiency test conducted in Casper, Wyoming at the RMOTC on March 29, 2012. The test report can be viewed at: http://www.rmotc.doe.gov/testreports.html. At this link on the U.S. DOE's website, readers may view both STWA's most recent March 2012 test results as well as its previous October 2011 test results.

STWA, the U.S. DOE's RMOTC, and Temple University's Dr. Tao, together tested the Company's Applied Oil Technology™ (AOT™) in a field test. The AOT™ 1.2H prototype achieved a 40.01% viscosity reduction, which led to the improvement of the test pipeline's pressure drop by 40.04%. This is a key measurement of pipeline capacity and efficiency for pipeline operators.

The Company recently signed a new five-year operating agreement with the U.S. DOE's RMOTC, which extends the parties' working relationship through the end of 2016. The purpose of the new operating agreement is to continue field testing STWA's technology and its future iterations for the next five years.

"We continue to have a very productive collaboration with the U.S. Department of Energy and its Rocky Mountain Oilfield Testing Center. We thank the entire DOE team for their work in conducting these tests and in presenting the validated results which highlight a technology that can play a meaningful role in U.S. energy independence and in reducing the cost of oil," stated STWA Chairman and CEO Cecil Bond Kyte.

About AOT™
STWA's Applied Oil Technology™ (AOT™) is designed to allow pipeline operators to temporarily reduce the viscosity of the crude oil within their pipeline(s) to reduce the fluid-drag (also known as friction-loss) between the fluid and the pipeline. By reducing the friction loss, pipeline operators' pump systems require less energy to maintain a constant flow rate, thereby directly reducing daily operation costs.

About STWA, Inc.
STWA, Inc. develops and commercializes energy efficiency technologies that assist in meeting increasing global energy demands, improving the economics of oil extraction and transport, and reducing greenhouse gas emissions. The Company's intellectual property portfolio includes 24 domestic and international patents and patents pending, which have been developed in conjunction with and exclusively licensed from Temple University. STWA's technologies include Applied Oil Technology (AOT™) which improves oil flow through pipelines. AOT™ has been proven in U.S. Department of Energy tests to increase the energy efficiency of oil pipeline pump stations by over 13%. ELEKTRA™ improves diesel engine efficiency for industrial diesel engines, as well as diesel-powered trucks, trains, marine vessels, military fleets and jet turbines.
