The turbines WITHOUT blades: Firm unveils radical `pole` design that claims to be quieter and safer than traditional wind farms
- The technology takes advantage of vorticity to generate electricity
- Vorticity is a wind effect that creates a pattern of spinning vortices
- Bladeless design could reduce manufacturing costs by 53 per cent
- Prototype ‘Vortex Mini’ can capture nearly half of the wind’s power
Today’s wind turbines have colossal blades that spin at speeds of more than 200mph (320 km/h).
While some might consider them majestic structures, others argue they are a threat to bird life and a noisy blight on the landscape.
Now a Spanish company has come up with a solution to ease opposition to the technology; a bladeless wind turbine that can generate more electricity for less.
HOW IT WORKS
- The long cone made from a composite of fiberglass and carbon fibre is designed to vibrate in the wind.
- Two rings of repelling magnets are positioned at the base of the cone, acting as a non-electric motor.
- When the cone moves one way, one of the magnets pull it another direction.
- This provides a boost to the mast’s movement, even when wind speeds are low, according to the company.
- The movements is transformed into electricity using an alternator that increases the frequency of the mast’s movement.
