Wind power is normally harnessed with the help of wind turbines that produce electricity when rotated by gusts of wind. Although initially the cost of turbines were rather high, it has become very affordable now on account of several factors. As these turbines are becoming more and more popular, they are being produced in bulk, as a result of which their prices have come down appreciably. Then there are ĎDo-It-Yourself wind power kitsí where one has to merely assemble the various parts available in the kit according to instructions provided with the kit. And lastly, some enterprising individuals make their own turbines from small electric motors, PVC blades, mechanical hubs, transformers that convert DC current generated by the turbine to usable AC current, electronic charge controllers and a conduit that is used as a mast to hoist the turbine 10 feet up from the surface. Even for an amateur enthusiast, these home made turbines cost no more than $100 since most of the ingredients can be fished out of any hardware store at a cheap price, while the electronic items are readily available as well.
to meet the growing demand for residential wind power
generator, people tend to experiment with various other
means to generate electricity from wind power, as a
result of which, several unconventional wind
machines have seen the light of the day. Windbelt Wind
Generator, invented by 28 year old Shawn Frayne of
a single Windbelt generator can produce 40 MW through a
10 mph wind, several such units set up in an array will
deliver the desired voltage. At present, the Windbelt
generator generates electricity in winds over 4 mph at
attack angles of up to 60 degree but as the wind speed
increases from 4 mph to 14 mph, the power output
increases at a rate close to the cube of the increase in
wind power may also be made through Mini Wind
Turbines that are usually found atop 5-meter poles in
farm houses or barns that are off grid. The generated
power coming out of these miniature wind turbines are
often stored in battery banks and passed through
inverters that deliver usable 120V or 240V AC current.
Though not very practical in everyday use, Mini Wind
Turbines do work as supplement to grid power, thereby
reducing the overall electricity bill.
for us, irrespective of being rich or poor, every
country whether in Asia, Europe or America is today
interested in utilizing renewable energy through wind,
solar or wave for the simple reason that fossil fuel
generated electricity creates enough harm, apart from
the fact that it is becoming more and more expensive
with each passing year. And as for wind energy, the day
is not too far when cheap wind power will become
affordable for all.
Personal wind power is great news because on the one hand it is clean and good for the environment, and on the other, it saves you on your power bills. But cheap wind power is even better. It is the right move to install such a system because of the tremendous advantages. But before you can gain from cheap wind power, you need to know a few things such as where to buy cheap parts from, safety precautions, choosing the best location and wiring the system.
