The Technology

Wind turbines are rotating elements with the potential to hit objects or birds near them. A high efficiency, green energy can be produced by means of actively controlled vortex shedding (ACVS). Reciprocating movement of element, in direction perpendicular to the direction of energy flow (waves or wind), generates energy using linear generator. The movement may be used for pumping or compressing gas for energy storage. By controlling the boundary layer by means of periodic active perturbations dramatic increase in amplitude of the oscillations is achieved and hence the efficiency of energy production increases.


  • High efficiency
  • No rotating parts

Applications and Opportunities

  • Generation of clean energy from gas and liquid flows
