Properties Unique to
the
"Green Windmill"
US
Patent # 5,823,749
 | Extreme simplicity |
| Vertical axis (rotational
power to ground level) |
| Omni-directional |
| No governors or controls
required for most applications |
| Light
weight |
| Self stabilizing (the rotor rides the wind) |
| Low cost |
| Easy to
maintain |
| High starting power in low
wind speeds |
| Silent
running |
| Self-damping sails insuring
durability |
| No transmission required in
many applications |
| Resides in a plane above the
top supporting journal * |
| Convenient hook-up to
appliances |
| Extremely versatile (size,
configuration,
application) |
| Minimal tower requirements
(roof mountable) |
| Easy installation (one person
installation) |
| Urban
compatible |
| Expands applications for wind
power |
| Easy to build (Cut and measure
parts, off-shelf
materials) |
| Serves both practical and
recreational
applications |
| Portable |
*Unlike
other vertical axis windmills, the "Green
Windmill" requires no supporting
bearing above the rotor. This means that the height of the tower is
unrestricted. The higher the tower, the greater the output.
Applications for the
"Green Windmill"
The system can be portable, or stationary, and can be made any size to
apply to your application and wind conditions. Some of the proposed
applications are listed below.
Rural
Units
(8' to 30' diameters
with tower)
Suggested
applications:
| Acid rain control
(neutralization via aeration of dugouts, lakes,
ponds) |
| Aeration, agitation
(preventing freeze-over and oxygen depletion of lakes, ponds,
dugouts) |
| Aqua culture maintenance |
| Air
compression |
| Irrigation |
| Drainage (featuring portable
application) |
| Water
Filtration |
| Desalination (salt removal
from water) |
| Sewage processing (including
farm run-off waste
control) |
| Domestic water pumping
(mechanical or air
operated) |
| Water or oil heating
(resistance heating) |
| Washing (clothing, fiber,
metal and gem stone prospecting) |
| Mining (portable ventilation,
water pumping, washing, tumbling, polishing) |
| Grinding (flour, feed, cement,
fiber) |
| Fiber processing (hammer
mills) |
| Pressing (oils, juice, fiber) |
| Ventilation (barns, chicken
coops, corn cribs,
granaries) |
| Boat propulsion
(omni-directional, no tacking required) |
See "Rural Applications" page for
details.
