An apparatus for generating electric current by the force of a fluid in motion. The device comprises a support structure; two substantially parallel axles positoned in an alterable vertically extending plane detachably supported by said housing and capable of rotation within the support means therefor; two substantially parallel wheels positioned on each of said axles and the wheels on one axle being in substantially the same vertically extending planes as the wheels on the other axle; two belts, one of which connects the two wheels in one plane and the other belt connects the other two wheels in the other plane; and a series of blades each one of which is detachably connected at the opposite ends thereof respectively to the two belts. In operation, fluid entering a second stage of a two-staged cascaded flow device consists only of fluid from the exhaust of the first stage of such device.
