STWA Receives Contract Payment from Pipeline Research Council International (PRCI) for Viscosity Reduction Testing of Applied Oil Technology (AOT™)

SANTA BARBARA, CA--(Marketwire - Sep 15, 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 it has received a contract payment from the Pipeline Research Council International (PRCI).

The Company received payment from the international consortium to co-fund the testing being conducted at the U.S. Department of Energy's Rocky Mountain Oilfield Testing Center (RMOTC) in Wyoming. The Company's technology is designed to reduce the energy consumed in the transmission of crude oil through pipelines by temporarily reducing the viscosity of the crude oil itself. The Company's technology has shown significant gains under laboratory conditions and has been confirmed to affect crude oil at a molecular level at the National Institute of Standards and Technology (NIST). The Company is currently testing its technology with the U.S. Department of Energy.

"This contract payment from PRCI marks another important milestone in our timelines for bringing our new technology to market," Mr. Cecil Bond Kyte, Chairman and CEO of STWA, Inc. "We are very grateful for the ongoing support we have received from PRCI moving things forward. This follows on the heels of a new, exclusive licensing agreement that we recently signed with Temple University, reflecting updated technologies and terms covering intellectual property related to STWA products, including our AOT™ prototype. These milestones represent important achievements that will benefit all parties for years to come."
