These kits may be used with any suitable tower on which the two bearings can be mounted. The tower shown in these views is from a well-known small decorative 8 foot tall yard windmill, Item #41293, which may be ordered over the Internet.

The rotor seen in these views has the special ENHANCED DEFLECTION, ULTRA-THIN PROFILE RATIO, DOUBLED blades that run on the lift principle. Easy startups. Plenty of rotational speed. Plenty of torque on the rotor shaft. Both kits come with everything necessary to assemble the rotor with 4 doubled blades, 4 rotor arms, and a shaft as seen in the two images above, including the bearings and a lower bearing plate. A generator may be purchased separately and added.

Both MicroRotators run quite well in front yards near a house and under trees, wind of only 5 to 10 mph being all that is necessary to create a modest amount of remote energy for any purpose.

Visual distortion of the rotor seen at right is an effect of digital imaging of the high speed motion.

MicroRotator Model 06 above seen on the upper left has a rotor diameter = 18" and blade length = 22". It rotates at high speeds and a small bicycle generator may be used on it or a small axial flux generator. Price for the kit - $124.95 plus $15 shipping, a further savings from earlier prices and effective through the month of September.

MicroRotator Model 07 above seen on the upper right is a newer design and has a rotor diameter = 24" and blade length = 22". It has blades with a wider chord width and produces more power than the model on the upper left, suitable for a DC generator such as the 30 volt Ametek seen at the bottom of the shaft in the view above and in many of the photos below. Price for the kit - $149.95 plus $15 shipping.

A free copy of the "Lift" booklet ( described below ) is included with all orders.

The MicroRotator Model 07 Seen Running In Various Locations

Please be patient while filling in the website data forms during ordering since repeated entries of information may be required by PayPal for security and back website form pages may time out. In any event, questions about the order or special requests may be sent via e-mail or fax message to IntegEner-W. See below for Contact Information. Orders taken at this time for shipment only to the U.S. and Canada. Warranted free from defects for 30 days following shipment and limited to one replacement of parts in question. Liability disclaimed for mishandling and misuse, especially for tower falls, including for consequent damage. In strong winds, blades of this type may turn at relatively high rates of rotation, requiring careful measurements made of the rotor arms for balance when assembling. Some edges and corners, though trimmed, may be sharp. Exercise care and use eye protection when using any power tools in working on metal parts such as these, not ordinarily necessary for assembly according to the directions provided.
Also, custom orders accepted for special wind rotor blade designs making use of small radius bends and folds in metal sheet similar to those seen in images on these pages. For any questions about these products or for quotes on custom orders, just use the "Contact Info" link in the navigation bar back on the Home Page

- - The "Aerodynamic LIFT" Booklet of IntegEner-W - - Now order either in hard copy or as a PDF or HTML document over the Internet.
	This booklet came into being in providing answers to many questions that are often asked regarding aerodynamic lift as it applies to flight and now wind energy. Lift is now well accepted as a consequence of Newtonian Principles (see the link to a page on the NASA website below), which forms the basis for its coverage, and extra details are added of a complete vector analysis of the forces present on a wing or blade. This brief treatise is complete with generalized, scalable formulas for lift and drag on aircraft wings and the corresponding driving and lateral forces on wind turbine blades.

A Collection of Wind Energy Internet Links of Interest
Many websites are available in support of those interested in pursuing various energy projects of their own. Here are just a few and from these more of them may be found. Our web site, in turn, would welcome being linked, where not already, from these:

The Bergey Legend continues, a name that has become almost synonymous with distributed small wind energy generation. Becoming more and more popular every year, the South West Wind Power turbines are setting standards of their own. The "grass roots" OtherPower is in the Colorado Rockies.
A dozen or two story threads at the OtherPower Site Small Wind Energy Pages of some interest are listed below:

Here is the story of The Early '40s Wind Power Dinosaur Of Vermont,
which was an amazing ( for its time ) 1.25 MW wind generator, illustrated with photos.

Here are early photos of
Poul la Cour of Denmark, the Danish Windpower Pioneer, and His Wind Turbine
from the late 1800s, considered by many to represent the beginning of modern windpower.
