Vengeance Power Inc. is an engine development company comprised of a highly talented and experienced crew in partnership with private investment groups. Our extensive background in automotive R&D, pioneering work in Rapid Prototyping/3D Printing and advanced 3-D CAD/CAE/CAM capabilities allows us to quickly transform a concept into a working model. We are presently working on new types of engines, motors, compressors and pumps to power a more efficient world with cleaner emissions, smaller carbon footprints and lower costs. We are also focusing on power generation from low grade waste heat. Our goal is to develop the technology for mass production and apply it to real world applications globally. We are presently reviewing licensing options for various applications, some of which include stationary & portable power generation, automotive, marine, aerospace, and defense.

The first Vengeance Power Engine ever built was chosen as the favorite of five best new engines when it made its debut at the 2009 SAE World Congress in Detroit, Michigan.

A more compact 6-Vane configuration of the Vengeance Power Expander Motor design was built and tested on compressed air as a dedicated expander which is not limited to any particular size. This was done in a real 1972 Corvette chassis and demonstrated on a chassis dynamometer providing tremendous torque at low speeds and pressures. This enables the use of any pressurized fluid to drive the Vengeance Power Expander including air (CAES), steam, ORC fluids, external combustion (Brayton cycle), supercritical fluids and pulse detonation. When running on steam, condensation occurring within the Expander as the fluid expands and cools had no negative effect. In fact, our Expander doubles as a formidable Hydraulic Motor providing incredibly high smooth rotary torque with no pistons. It can also run in reverse as a compressor or pump.

Working with our academic community to advance research and development, we give students the opportunity to work with the latest industrial technologies while also supporting our local economy.


The Vengeance Power Engine successfully ran on the Brayton Cycle. Our proprietary External Combustion / Pulse Detonation Wave device was mounted on the engine and various fuels including gasoline were combusted to provide the force to spin the output shaft. The addition of the Brayton Cycle makes it possible to raise the efficiency by combining the Rankine Cycle which allows the engine to run on both cycles simultaneously. The Brayton Cycle in conventional turbines requires high velocities since they do not have sealed expansion chambers. Because the Vengeance Power Engine has sealed expansion chambers, the speed required to do work is much lower. This makes it a true positive displacement sealed turbine engine.

Vengeance Power Inc. was recently awarded the Professional Engineers of Ontario (PEO) award for the Innovation Challenge Competition in September, 2012.

Successful first test of our prototype Hybrid Radial Impulse Steam Turbine featuring low rpm, high torque, low cost, simple manufacturing and maintenance.

In December 2012, Vengeance Power Inc. was chosen by a world military supplier to begin discussions on implementation for waste heat recovery applications in battlefield / tactical applications.


The engine ran successfully on external combustion using steam proving out the Rankine Cycle. This demonstrated the engine’s ability to run on waste fuels and as a waste heat engine. A torque output test also proved the tremendous torque output predicted in the CAD model. These tests also demonstrated the engine as a viable Organic Rankine Cycle engine using refrigerant vapor pressure from low-grade waste heat sources. Compressed air tests demonstrated the wide range of applications including CAESP (Compressed Air Energy Storage & Power) systems.


Successful internal combustion firing tests proved out the Otto Cycle concept where all four strokes of Intake, Compression, Power and Exhaust were demonstrated.

Vengeance Power Inc. was recognized as a Society of Automotive Engineers (SAE) Industry Innovator at the 2010 SAE World Congress in Detroit, Michigan.
