SANTA BARBARA, CA--(Marketwire - Jun 24, 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 the U.S. Department of Energy's (DOE) Rocky Mountain Oilfield Testing Center (RMOTC) has highlighted the testing of the Company's Applied Oil Technology (AOT™) for reducing the viscosity of crude oil in Wyoming Energy News on June 23, 2011.

The article announces the U.S. Department of Energy's support for the testing of a full scale AOT™ product prototype currently taking place at its RMOTC's facility in Casper, Wyoming. The RMOTC's Deepwater Testing Facility allows for field-scale testing on a live oil pipeline that can simulate the harshest conditions associated with both onshore and offshore oil production. AOT™ has already been proven in laboratory tests to reduce crude oil's viscosity. Testing at the RMOTC is designed to measure the value AOT™ has to the industry and key stake holders in reducing the cost of transporting crude oil through pipelines under real world conditions.
