Bladeless Wind Turbine
Vortex Bladeless Ltd. is a Spanish technology startup company that is developing a type of wind power generator without rotating blades or lubricants, unlike the more common wind turbines. Power is produced from resonant vibrations produced when wind passes the turbine and is deflected into vortices in a process called vortex shedding.
This technology has some traits which are more similar to solar power than to large wind turbines, such as being better suited to autonomous operation and distributed generation of energy off the grid, for and on low-power systems.
Typical energy returns:
– Vortex Nano – 1 metre (3.3 ft) high and 3 W nominal power output. Designed mainly to bring energy to off-grid locations for low-power systems, working along with solar panels. Stage: pre-production of a first beta series.
– Vortex Tacoma – 2.75 metres (9.0 ft) high and 100 W nominal power output. Designed mainly for small-scale residential and rural autonomous operation, working with solar panels. Stage: prototype, being developed.
– Vortex Atlantis/Grand – 9–13 metres (30–43 ft) high and around 1 kW nominal power output. Designed for residential and rural autonomous operation and complementary installation with solar panels over buildings and factories. Stage: projected but not being developed yet.
