Alternative Power Solutions Using Vertical Axis Wind Turbines
Midwest Alternative Power specializes in vertical axis wind turbines. VAWT Vertical axis wind turbines VAWT are capable of producing from 1 kwh to 2.5 mega watts hours of electricity with the aid of additional wind directors. The generators can be monitored remotely via high-speed Internet, DSL, satellite or cellular means using remote monitoring software.
Wind can be captured from nature or as a by-product from exhaust fans or by convection heating. This type of turbine can be used in ways the horizontal axis turbines cannot be used because of design features and with the use of wind deflectors to assist with capturing more wind.
Vertical axis wind turbines are an old concept but will revolutionize the wind industry with the design and new applications.
Vertical axis wind turbines.... the future in wind power
Vertical-axis wind turbines VAWTs have the main rotor shaft arranged vertically. Key advantages of this arrangement are that the turbine does not need to be pointed into the wind to be effective. VAWTs can utilize winds from varying directions.
When a turbine is mounted on a rooftop, the building generally redirects wind over the roof and this can double the wind speed at the turbine. If the height of the rooftop mounted turbine tower is approximately 50% of the building height, this is near the optimum placement for maximum wind energy and minimum wind turbulence.
Vertical Axis Wind Turbines - VAWT Advantages of Mariah Power and Franklin-Thomas Turbines
- In most cases, no massive tower structure is needed.
- As the rotor blades are vertical, no yaw mechanism is needed.
- A VAWT can be located nearer the ground, making it easier to maintain the moving parts.
- VAWTs have a higher airfoil pitch angle, giving improved aerodynamics while decreasing drag at low and high pressures.
- Straight bladed VAWT designs with a square or rectangular crossection have a larger swept area for a given diameter than the circular swept area of HAWTs.
- VAWTs have lower wind startup speeds than HAWTs. Typically, they start creating electricity at 6 m.p.h. (10 km/h).
- VAWTs usually have a lower tip speed ratio and so are less likely to break in high winds.
- VAWTs may be built at locations where taller structures are prohibited.
- VAWTs situated close to the ground can take advantage of locations where mesas, hilltops, ridgelines, and passes funnel the wind and increase wind velocity.
- VAWTs do not need to turn to face the wind if the wind direction changes.
- VAWT blades are easily seen and avoided by birds.
- Wind deflectors or directors can be constructed to increase the swept area and therefore increase potential power production.
