Abstract
A rotatable impeller is a hollow conical/cylindrical stack, with at least one slanted/vertical side portion and at least one level of stack portions. Each impeller comprises at least one shape of airfoil/hydrofoil for thrust to propel, or pull, i.e., to draw in, vapor or fluid; plus a dynamic application utilizes a reverse operation to generate electricity from the kinetic energy of the flow of vapor or fluid. One airfoil/hydrofoil configuration of a stack impeller comprises serpentine rectangular segments positioned by internal rib members. Considered additional levels are enlarged copies of the first level of the stack impeller, positioned at an engineered distance from each level, and are considered to amplify propulsive or vacuum force; or for energy recovery to operate a dynamo generator.
