The design replaces the piston and cylinder architecture of conventional engines with a purportedly novel mechanism called the Internally Radiating Impulse Structure, or IRIS.
The inventors claim that this innovation will reduce waste heat and will increase the amount of surface area the engine has available to produce torque.
[4] IRIS engines are designed to run on traditional fuels, but could also be adapted to use biodiesel, natural gas, or hydrogen.
IRIS chamber technology could also be utilized to create pumps, compressors and medical devices.
Three of his sons, Corban, Levi, and Tomicah Tillemann-Dick, also contributed to the design and are credited on patent applications relating to the IRIS engine.
