Organization, Consolidation, Basis Of Presentation, Business Description and Accounting Policies [Text Block] | Note 1 – Organization and Description of Business ClearSign Combustion Corporation (ClearSign or the Company) designs and is developing technologies for the purpose of improving key performance characteristics of combustion systems, including emission and operational performance, energy efficiency and overall cost-effectiveness. The Company’s primary technology is its Duplex™ technology, which achieves very low emissions without the need of external flue gas recirculation, selective catalytic reduction, or higher excess air operation. Its other technology, Electrodynamic Combustion Control™ or ECC™, introduces a computer-controlled electric field into the combustion region which may better control gas-phase chemical reactions and improve system performance and cost-effectiveness. The Company is headquartered in Seattle, Washington and was incorporated in the state of Washington in 2008. Going Concern The Company’s financial statements have been presented on the basis that it is a going concern, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The Company’s Duplex technology is currently in various states of commercial application regarding in three of the Company’s target markets and has generated nominal revenues from operations to date. Results are encouraging but the Company continues to further refine and expand our Duplex technology range. The Company’s ECC technology is in development stage and the Company has not had any commercial application of ECC technology to date. In order to generate meaningful revenues, one of the technologies must be fully developed, gain market recognition and acceptance, and develop a critical level of successful sales and product installations. The Company has incurred losses since its inception totaling $47,418,000 and expects to experience operating losses and negative cash flow for the foreseeable future. As of September 30, 2017, the Company had cash and cash equivalents totaling $3,511,000. The Company currently anticipates that its cash and cash equivalents will be sufficient to fund the Company’s ongoing business activities into the first quarter of 2018. In order to continue business operations beyond that point, the Company currently anticipates that it will need to raise additional capital. The Company has historically financed its operations primarily through issuances of equity securities, and until the growth of revenue streams increases to a level that covers operating expenses it is the Company’s plan to continue to fund operations in this manner. Management believes that the successful growth and operation of the Company’s business is dependent upon its ability to obtain adequate sources of funding through equity or debt financing, co-development agreements or strategic partnering agreements to adequately support research and development efforts, protect intellectual property, form relationships with strategic partners, and provide for working capital and general corporate purposes. Management has made estimates of future results of operations, using a wide range of assumptions regarding the level of revenue generated, operating expenses incurred, and future cash flows from financing activities and is working to execute these plans. While historically the Company has had success in raising capital, there can be no assurances that the Company will raise the necessary capital in the short-term in order to fund operations beyond the first quarter of 2018. Furthermore, there can be no assurance that the Company will be successful in achieving its long-term plans, or that such plans, if consummated, will enable the Company to obtain profitable operations or continue in the long-term as a going concern.
