Wind Power and Wind Generators
Welcome
to hoosacwind.com! Our Web site is dedicated to de-mystifying wind power.
Whether you’re looking for information on zoning restrictions
for a residential wind turbine, or you just want to know what makes
these bad boys tick, you’ve come to the right place. We are constantly
updating in response to your suggestions, so if you see anything that
you think should be included in our site, or have questions, please
email us. Our FAQs are built out of questions from people just like
you.
Wind power has been harnessed by mankind for generations. The first
people to utilize the wind’s power to do work were sailors. They
understood that if you opened a sheet to the breeze, the sheet would
pull on your arms. They utilized the difference between wind direction
and velocity, and the water’s direction and velocity to propel
their craft.
Centuries would pass by before we found another reliable use for wind
power, windmills! These giant buildings could harness the wind’s
power to roll heavy grindstones. The cows in Belgium are grateful to
this day for the break they caught when the Dutch tried this new technology
out.
Yet more centuries would pass before wind power made the transition
from mechanical mover to electrical impetus. The concept for electrical
generators was invented in the early part of the 19th century. The concept
itself was remarkably simple. If you rotated magnets around a conductor,
it created a current. The concept of current is distinct from creating
electricity. The electrons were there prior to the magnets’ arrival.
The magnets simply set the electrons in motion along the conductor.
The strength of the current created depended on the conductive abilities
of the material used, as well as the strength of the magnet.
Since that invention, nearly every attempt at electric generation has
included a coiled conductor, and electromagnets. It’s surprising
then, that it took as long as it did to make the jump to using the wind
to rotate the magnet. It was not until after the invention of the propeller
driven aircraft that mankind put the pieces together and realized that
an aerodynamically created propeller could be used as the impetus for
power as well as the impetus for forward velocity, if it were merely
kept in place.
The rest, as they say, is history. Once we discovered that we could
spin a magnet with a propeller, we simply put the propellers up on sticks
to get them into the wind. The higher the wind, the more current the
wind generators could produce. There is a bright future in wind power.
For instance, the two largest areas of sustainable wind power remain
largely untapped.
Just a few miles off the shore of any body of water large enough there
are constant winds. These winds are caused by two factors. The first
is that land and water absorb sunlight differently. The second is that
out on the water, there are no impediments to the wind. This means that
slight breezes encounter nothing to stop or slow them down, the way
they do on land. The breezes build a head of steam and are soon strong,
prevailing winds that nearly never cease. The primary restriction right
now to reliable off shore wind power is the cost of installation. The
platforms for generating the power must be anchored to the sea bed,
which is a costly process.
More impressive than that however, is the wind that can be found in
the atmosphere even a single mile above the surface of the earth. These
winds blow at over 100 miles per hour, and are always blowing! As opposed
to the sea wind power, upper atmosphere wind has technological hurdles
that must be overcome before we can even dream of tapping it. We’d
need a way to use the wind to create an electrical current, which means
that something would have to be stationary at that height. With the
amount of friction that would occur with that kind of airflow, that’s
no mean feat.
However there are still far more practical, down to earth methods of
harnessing wind power. A wind turbine can
comfortably fit in your back yard- without taking over the place. They
can form a much needed buffer between you and rising energy costs, as
well as reducing your carbon footprint.
