Doing Without Blades
Vortex Bladeless is a technology that uses the vortex effect. Basically, Vortex Bladeless consists of a conical cylinder fixed vertically on an elastic rod. The cylinder oscillates in the wind, which then generates electricity through a linear alternator’s system.

In Vortex Bladeless the outer inverted conical cylinder is designed to be effectively rigid while still being able to oscillate freely because it is fixed at its base to a flexible supporting rod. The top of the cylinder is unconstrained and has the maximum amplitude of the oscillation. The structure is built using resins reinforced with carbon and/or glass fibre, materials used in conventional wind turbine blades.
