ADVANTAGES CONCLUSION

Introductiono The Spanish company named Vortex

Bladeless recently unveiled their design for a wind turbine that generates electricity without the need of rotating blades.

o In what one of the co-designers described as looking like “asparagus", the turbine uses the force created by natural wind vortices to generate electricity.

o Vortex Bladeless, on the other hand, designed their turbine to take advantage of this effect.

o David Yanez is part of a team inspired by the motion that collapsed the bridge to create a bladeless wind turbine

WORKING AND OPERATION OF BWT o The Vortex wind generator

represents a fairly radical break with conventional wind turbine design, in that it has no spinning blades (or any moving parts to wear out at all), and looks like nothing more than a giant straw that oscillates in the wind.

o Finally the model is of a new wind turbine prototype. Based on field testing, the Mini ultimately captures 30 percent less than conventional wind turbines, but that shortcoming is compensated by the fact that you can put double the Vortex turbines into the same space as a propeller turbine.

o A big change may be coming to the design of wind turbines of the future and the future may have no blades. Vortex Bladeless claims its first generation of bladeless wind turbines would generate electrical power in essentially the same way.

o 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. The energy contained in moving air is proportional (among other things) to the air mass, which in a wind turbine setting is proportional to the capture cross-section.

o . Vortex claims that their wind turbine can adapt to any wind speed with the assistance of the magnets in its core.

.Vortex is much smaller than traditional wind turbines, allowing you to use your space more efficiently.

OSCILLATORY TECHNOLOGY o Vortex Bladeless has developed

turbines that harness vorticity, the spinning motion of air or other fluids.

o When wind passes one of the cylindrical turbines, it shears off the downwind side of the cylinder in a spinning whirlpool or vortex. That vortex then exerts force on the cylinder, causing it to vibrate.

o The kinetic energy of the oscillating cylinder is converted to electricity through a linear generator similar to those used to harness wave energy.

DEMONSTRATION OF BWT Generously assuming a 5% capacity

factor, you'd actually need about 4,000 Vortex turbines to equal the same amount of power from one single modern wind turbine.

RAUL MARTIN, VORTEX BLADELESS CO-FOUNDER, SAID, "COMPARE OUR INVENTION TO A CONVENTIONAL WIND TURBINE WITH SIMILAR ENERGY GENERATION--OURS WOULD COST SIGNIFICANTLY LESS," ROUND 50 PERCENT OR 47 PERCENT LESS.

so as to maximize some "value" that the wind turbine has overall, While a traditional wind turbine uses the spinning of the propeller to create energy, the Vortex turbines will use an aerodynamic effect known as voracity.

ADVANTAGES OVER CONVENTIONAL WIND TURBINES

No gears and bearings,reduces manufacturing and manitainance drastically.

No lubricants needed,noise less,more environmental friendly.

More efficient. It reduces foundation at the

bottom by 50%. Birds can fly around them

without fear of being sucked in.

CONCLUSION The system is mainly adaptable with

lighter material and low maintenance cost, hence there is ease in installation within the specified space in huge amount

The cost of power generation per hour will be 40% less than the conventional wind turbines. There is future growth in this bladeless wind turbine with more accurate in the power generation with high Megawatt/hr.
