ClearSign develops technology intended to increase energy efficiency and emissions standards of combustion systems, primarily industrial and commercial boilers and furnaces. Its products include Duplex Burner Architecture, which the company says reduces combustion burner flame length by more than 80-percent, in turn increasing thermal capacity and reducing operating costs. Duplex Burner Architecture won the "New Technology Development of the Year Award" at the 2014 West Coast Oil & Gas Awards.{{cite web |url=http://www.oilandgasawards.com/winner/west-coast-2014-new-technology-development-of-the-year-award-clearsign-combustion-corporation/ |title=New Technology Development of the Year Award, West Coast 2014 |website=oilandgasawards.com |publisher=Oil & Gas Awards |access-date=13 January 2015}} The company's other major product is Electrodynamic Combustion Control, which uses computer-controlled electric fields to control the flame shape in boilers, kilns, and furnaces, preventing pollution from forming.{{cite web |url=http://www.clearsign.com/technology/ |title=ClearSign Technology |website=clearsign.com |publisher=ClearSign Combustion |access-date=13 January 2015}}{{cite news |last=Wogan|first=David |date=17 December 2013|title=Flame-Taming Electric Fields Could Make Power Plants Cleaner |url=http://www.scientificamerican.com/article/flame-taming-electric-fields-power-plants/ |newspaper=Scientific American |access-date=13 January 2015 }}
