The Mag-Wind™ System, or Maglev Vertical Axis Wind Turbine (MVAWT), is a magnetically levitated wind turbine technology that reduces friction, noise, vibration and energy loss.

It is designed to work in low wind environments.

Produced originally by Mag-Wind Company, LLC, Enviro Energies has acquired the license to manufacture and further develop this technology.

Products are sold through authorized distributors who have access to the resources to also do installations worldwide.

The inverter that is being built for this unit is now available. The first production model will be delivered to International Home Builders Show in Las Vegas Nevada in January 2009 and then set up on Jay Leno’s garage.

How it Works

Maglev Vertical Axis Wind Turbine
"Designed to last an estimated 20 years, Mag-Wind features no gears to wear or freeze. Its platform of aluminum sails, or wings, float on magnets. The platform base rotates around a stabilizing, vertically fixed shaft through its center. A circle of magnets on the inside of the base pass by a circle of coils to create electricity." (Dallas Business Journal''; Dec. 25, 2005)
""A roof with a 10-foot vertical rise and a 30% angle will provide nearly a 200% increase in the amount of wind energy that is available to be turned into electricity. Compared to the same turbine just sitting on a pole, the roof effect increases the power yielded by operation of the wind turbine dramatically." (TreeHugger; Jan. 22, 2007)

Costs

  • 1.5kW MVAWT $7K USD for homes.
  • 5kW MVAWT $21K USD for residential or commercial.
  • 10kW MVAWT $40K USD for large commercial.

Factor in shipping, installation and electrical power as added expenses.

Advantages

  • Maglev operation - no bearings to wear out. No mechanical wear or friction, reducing noise, vibration and energy loss.
  • Vertical Axis Wind Turbine with sails that can receive wind forces from any direction. Including up and down winds.
  • Axial Flux Alternator – Allows it to generate large amounts of electricity at low rotational speeds.
  • Roof Mounted – Does not require a tower, allows the wind turbine to take advantage of air-compression velocity increases from roof effect.
  • Programmable Variable Coil Resistance – allows the increase of magnetic resistance as the wind speed increases. This reduces the cut-in wind speed required for electricity generation.

Applications

  • Wind turbine
  • The 10kW MVAWT, the most popular model, has been the “Hawaii Sail” version, which has sails 8 feet tall by 14 feet wide and was originally designed for the requirements of the Hawaiian market.

Independent Testing

The 5kW MVAWT will produce on average 1100 kWh per month which is enough electricity for an average home. NCRC have deployed 29 prototypes; with the final 3 prototypes (beta units) deployed in early 2008 in Canada and Italy.

Abstract
A lift and drag-based vertical axis wind turbine in which the vertical axis and foils mounted thereon are magnetically levitated above the turbine's base, thereby reducing friction within the system. The foils or vanes are three-dimensionally shaped about the vertical axis so as to resemble the billowed sail of a sailing ship and capture wind through 360 degrees of rotation under any wind condition. The system has an axial flux alternator using variable resistance coils which can be individually and selectively turned on or off depending on wind conditions and electrical draw requirements. The coils can also be used to produce mechanical drag on the system as desired to brake the turbine in high wind conditions or for maintenance. The system may be programmed to assess whether electricity generated by the system can be or should be transmitted to a public grid or stored locally on a chargeable battery system. Diagram

Company:Enviro Energies

Ken Johnson

Enviro-Energies acquired the License to manufacture and sell the Mag-Wind™ wind turbines.

Engineering - The engineers from CPE, RWDI, SBW, PV Eng., and Mechanical Systems Design are all working on this turbine system.

CPE Division "L" Inc. has been a leader since 1985 in the field of power protection, offering the highest quality of Uninterruptible Power Systems and related products in the industry including UPSs ranging from 500VA to 5MVA and more.

CPE is the company that has designed and is manufacturing the Enviro-Energies 10kW and soon the Enviro-Energies 50kW inverters.

SBW is the company that was the project leader in the final design and engineering of the sails and upper rotational assembly. They are also the manufacturers of the sails.

Inventors

Mag-Wind was invented by Canadians James A. Rowan and Thomas J. Priest-Brown.
