FOR IMMEDIATE RELEASE

CLEARSIGN COMBUSTION CORPORATION

SELECTED TO SHOWCASE ELECTRODYNAMIC COMBUSTION CONTROL™ TECHNOLOGY AT MDB CAPITAL GROUP'S 3RD ANNUAL BRIGHT LIGHTS CONFERENCE IN NEW YORK CITY

SEATTLE, WA – AUGUST 27, 2012 - ClearSign Combustion Corporation (Nasdaq: CLIR), an emerging leader in combustion and emissions control technology for industrial, commercial and utility markets, is pleased to announce that it has been selected to present at the MDB Capital Group's prestigious 3rd Annual Bright Lights Conference, which will take place from September 9th - 11th at the New York Palace Hotel in New York City. ClearSign will be presenting on the morning of Monday, September 10th.

Bright Lights is Wall Street's only disruptive technology conference, focusing exclusively on companies MDB believes can transform their industries with game changing technology.

ClearSign was hand-selected by MDB as one of approximately 30 public and private companies to present at this exclusive, invitation-only event.

"We are very excited, following our successful IPO in April, to share the ClearSign story with the audience at this prestigious event," said ClearSign CEO, Rick Rutkowski.

“Combustion-driven thermal processes account for roughly two-thirds of global energy consumption and production,” Rutkowski continued. “We believe that ClearSign’s innovative Electrodynamic Combustion Control™ (ECC™) technology offers significant advantages in the design of industrial and utility scale combustion systems. We are developing powerful new combustion control techniques that we believe may improve energy efficiency, and increase process throughput while significantly improving the economics of air pollution control and industrial production.

“According to the McIlvaine Company, the market for air pollution control was estimated to be just under $42 billion last year. We hope to provide insight into the market opportunity facing ClearSign, and the advantages of our novel approach to combustion systems design. We will also highlight key elements of our strategy and the milestones that lie ahead on our path to commercialization and will report on recent achievements.”

Christopher Marlett, CEO at MDB Capital Group, commented, "It's a rare and exciting opportunity to have so many key players that are advancing some of today's most innovative technologies together under one roof. We look forward to sharing ClearSign's ECC technology with other innovators and investors at Bright Lights 2012."
