About QS Energy, Inc.

QS Energy, Inc. (ticker: QSEP) is a U.S.-based energy technology microcap company currently quoted on the OTC market, not NYSE or NASDAQ, according to its latest investor and SEC disclosures. The company is organized in the United States and has long been associated with Santa Barbara, California, while its investor-relations contact information also points to Sherman Oaks, California. QS Energy was incorporated in 1998 as Mandalay Capital Corporation, later renamed Save the World Air, Inc., and adopted its current name, QS Energy, Inc., in 2015. From an equity-research perspective, it is best viewed as an early-stage commercialization story with a long operating history, limited revenue generation, and a continuing reliance on external capital.

Management describes AOT as a solid-state system that uses a high-voltage, low-amp electric field to reduce crude oil viscosity, improve pipeline flow, and potentially lower operating costs and emissions associated with oil transport. QS Energy also references prior work in flow-assurance and friction-reduction technologies aimed at upstream and midstream oil and gas applications. In practical terms, the company is positioned as a specialist in a narrow segment of pipeline optimization rather than as a broad-based oilfield services provider.

QS Energy’s main potential differentiators are its intellectual property portfolio, its patented technology stack, and development partnerships, including licensed IP connected to Temple University. However, the company’s filings also make clear that commercialization remains the central challenge: it has reported no meaningful sustained revenue base, recurring losses, and an ongoing need to raise additional funds to support R&D, product manufacturing, sales and marketing, and public-company compliance costs. That combination makes the stock a high-risk, execution-driven situation. ([sec.gov](https://www.sec.gov/Archives/edgar/data/1103795/000168316826002551/qsenergy_i10k-123125.htm?utm_source=openai)) Recent company updates have emphasized commercial milestones, strategic partnerships, and progress toward broader deployment of AOT. In 2024 and 2025, QS Energy highlighted initial orders, multi-year deployment discussions, distribution arrangements, and manufacturing readiness as it moved toward global commercialization. The company also stated that it is advancing toward full-pipeline deployment and broader international rollout opportunities. For investors in the United States, France, Belgium, or Switzerland, the key takeaway is that QS Energy is a small U.S. energy-tech issuer with real industrial ambitions, but one that still faces material financing, scale-up, and adoption risks before the investment case can be considered durable.
