Clearsign Combustion Corporation (Clearsign) designs and develops technologies that aim to improve key performance characteristics of combustion systems including energy efficiency, emissions control, fuel flexibility and overall cost effectiveness. The Company�s technology introduces a computer-controlled electric field into the combustion zone to allow for more precise control of flame shape and heat transfer. This same technique can also be used to modify the complex chemical reactions that occur during combustion in order to minimize harmful emissions while maximizing system efficiency.The Company's technology consists of four components: a computer, standard software delivering algorithms to a power amplifier (resident outside the combustion chamber) and electrode (inside the combustion chamber). The electrodes are optimized in material and shape to suit the specific geometry of a given installation.
