Commercializing a fuel-flexible high-efficiency engine and power generator to cut emissions and boost reliability.

• Fuel versatility: Prototype engines have operated on gasoline, diesel, ethanol, natural gas, LPG, and pure hydrogen.
• High efficiency: Spark-assisted turbulent low-temperature combustion targets thermal efficiency above fifty percent.
• Compact power: Power Cube concept packs up to one hundred kilowatts into roughly one square meter.
• Patent protection: Issued U.S. and international patents cover the core REV Force engine architecture.
• OEM engagement: Active discussions with major manufacturers to explore licensing and joint development paths.

Alpha-Otto Technologies is developing a patent-protected internal-combustion engine architecture that aims to deliver higher efficiency and lower emissions by combining a two-stroke power cycle with rotary-valve induction and spark-assisted low-temperature combustion. The design is fuel-flexible: laboratory prototypes have run on gasoline, diesel, ethanol, compressed natural gas, liquefied petroleum gas, and pure hydrogen with minimal hardware changes. By decoupling air management from displacement, the platform targets power densities suitable for mobile, stationary, and hybrid-electric applications while reducing criteria pollutants and carbon output.

Funds from this raise will finalize a two-cylinder 600 cc demonstration engine and integrate it into the “Power Cube,” a compact generator that couples the new engine with an axial-flux electric motor to supply up to 100 kW of on-demand power. The company’s go-to-market plan centers on pilot projects for data centers, defense, and micro-grid operators, followed by licensing or joint-venture agreements with established engine OEMs. Successful demonstrations could position Alpha-Otto’s technology as a transitional pathway for industries that need reliable combustion power today while preparing for hydrogen and ammonia fuels in the future.

Alpha-Otto Technologies develops a fuel-flexible high-efficiency engine and compact generator platform for transportation and distributed power applications.

Alpha-Otto Technologies designs and tests a patent-protected internal combustion engine platform called REV Force plus STLTC that reconfigures conventional two-stroke architecture to deliver a power stroke every revolution and precise air-exhaust management through a rotary valve. The engine operates on a wide range of liquid and gaseous fuels—including gasoline, diesel, JP-8, ethanol, methanol, ammonia and hydrogen—without major hardware changes, and targets thermal efficiencies above 50 percent with substantially lower criteria emissions. The company has built and run multiple prototypes funded by federal research grants and demonstrated stable combustion on fuels from compressed natural gas to 100-percent hydrogen.

Leveraging the same architecture, Alpha-Otto is developing the Power Cube, an integrated generator that pairs the high-density engine with an axial-flux electric motor to produce up to 100 kilowatts from a compact, lightweight package. The modular unit is intended for distributed power, data-center backup, mobile and defense applications, and can be clustered for microgrid installations. Rather than manufacturing at scale itself, the firm pursues licensing or joint-venture arrangements with established engine original-equipment manufacturers while outsourcing initial production to existing suppliers, positioning the technology for faster adoption across transportation, industrial and power-generation markets.
