1. Description of Business Description of Business QS Energy, Inc. (QS Energy, Company) was incorporated on February 18, 1998, as a Nevada Corporation under the name Mandalay Capital Corporation. The Company changed its name to Save the World Air, Inc. on February 11, 1999. Effective August 11, 2015, the Company changed its name to QS Energy, Inc. The Companys common stock is quoted under the symbol QSEP on the Over-the-Counter Bulletin Board. More information including the Companys fact sheet, logos and media articles are available at our corporate website, www.qsenergy.com. QS Energy develops and commercializes energy efficiency technologies that assist in meeting increasing global energy demands, improving the economics of oil extraction and transport, and reducing greenhouse gas emissions. The Company's intellectual properties include a portfolio of domestic and international patents and patents pending, a substantial portion of which have been developed in conjunction with and exclusively licensed from Temple University of Philadelphia, PA (Temple). QS Energy's primary technology is called Applied Oil Technology (AOT), a commercial-grade crude oil pipeline transportation flow-assurance product. Engineered specifically to reduce pipeline pressure loss, increase pipeline flow rate and capacity, and reduce shippers reliance on diluents and drag reducing agents to meet pipeline maximum viscosity requirements, AOT is a 100% solid-state system that reduces crude oil viscosity by applying a high intensity electrical field to crude oil feedstock while in transit. The AOT product has transitioned from the research and development stage to initial production for continued testing in advance of our goal of seeking acceptance and adoption by the midstream pipeline marketplace. The Company also began commercial development of a suite of products based around the Joule Heat technology. The Company began fabrication of prototype equipment to be operated under a joint development agreement with a commercial entity in the fourth quarter of 2014. The Companys first Joule Heat prototype was installed for testing purposes at the Newfield facility in June 2015 and the system was operational; however, changes to the prototype configuration will be required to determine commercial effectiveness of this unit. In addition, the Company filed two additional provisional patents related to the technologys method and apparatus. In December 2015, we temporarily suspended Joule Heat development activities to focus Company resources on finalizing commercial development of the AOT Midstream. We currently plan to resume Joule Heat development in in the future depending on the availability of sufficient capital and other resources. Going Concern The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the settlement of liabilities and commitments in the normal course of business. As reflected in the accompanying consolidated financial statements, during the twelve-months ended December 31, 2018, the Company incurred a net loss of $3,059,000, used cash in operations of $1,476,000 and had a stockholders deficit of $1,482,000 as of that date. These factors raise substantial doubt about the Companys ability to continue as a going concern within one year after the date that the financial statements are issued. The ability of the Company to continue as a going concern is dependent upon the Companys ability to raise additional funds and implement its business plan. The financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern. At December 31, 2018, the Company had cash on hand in the amount of $1,153,000. Management estimates that the current funds on hand will be sufficient to continue operations through September 2019. We will need to raise additional funds in in 2019 and beyond, primarily through the issuance of debt and equity securities for cash to operate our business, including without limitation the expenses it will incur in connection with the license and research and development agreements with Temple University; costs associated with product development and commercialization of the AOT technology; costs to manufacture and ship the products; costs of maintaining our status as a public company by filing periodic reports with the SEC and costs required to protect our intellectual property. In addition, as discussed below, the Company has substantial contractual commitments, including without limitation, payment of license and other fees to Temple University, salaries to our executive officers pursuant to employment agreements, certain payments to a former officer and consulting fees, during the remainder of 2019 and beyond. No assurance can be given that any future financing will be available or, if available, that it will be on terms that are satisfactory to the Company. Even if the Company is able to obtain additional financing, it may contain undue restrictions on our operations, in the case of debt financing or cause substantial dilution for our stockholders in case of equity financing.
