Hi 221,
I read the article on the above website, thanks. I also read a lot of if's
and but's which add-up to a lot of speculation. What is this guy saying
is not proven and not even noticed yet by others.
The facts are;
1. Burning coal, oil, natural gas etc is proven to hurt the environment due
to emmisions.
2. Nuclear power plants are not safe either. It is proven that a fair amount
of nuclear waste is dumped "somewhere" and takes 250 years to deactivate,
not to mention meltdown accidents like Chernobil.

Conventional ways (items 1,2) are PROVEN to harm the enviroment. Wind
turbines still provide clean energy without all the stuff you see listed above.

Care to comment? Regards...Georgios.

From my point of view, it will be a good add on regarding the entire energy mix and an adequate response to the demand for energy by using renewable energies ... still that solution is not yet found or at least ready to get implemented once fossil energy sources such as oil will be used up in the near future.

Hello Benny,
Everybody knows fossil fuels are running out. The fact that demand for
power and energy has doubled will make fossil fuels run out even faster.

If by the year 2040 renewable energies are below 30% of the world demand,
we are in deep trouble. Nearly all the industrial countries have research
programs in place to explore and exploite alternative energy sources. They
know the problem but few are willing to tell us.

Lets hope it wont come to that...Georgios.

I currently live in England and I have a house in Sosua North Coast.
I am heavily invloved in wind power in England and i am shipping my generator out to the DR for tests with my Invertor.I have loads of data on average wind velocities.I would be interested in exchanging information.

Hello Steve Allen,
I am flying into Puerto plata on monday Nov 15, 2004. Sounds like a meeting
between us may prove usefull for both. Please PM me your cell #. I will
call you when I get there...Georgios.

My new wind turbine design is rated at 10kw, stand alone+battery charging
availability. Special mesh to prevent bird killing provided. Good wind site
essential. Facing north, northeast into the ocean is ideal. I performed
numerous testing at cabarete, sosua and playa grande with favorable
results and good wind speed. Hill tops also suitable.
I like to hear from DR residents any comments about the power solution
using wind power. Thank you.

Hi Geogios,

I live in the Playa Grande, Cabrera region at about 700 feet elevation off the coast. I’ve been monitoring the wind speeds for over two years. My average annual wind speed is around 6.5 M.P.H. I presently produce all my power with a 24.5 Kw generator, two 3.6 kw inverters, 32 batteries and a few solar panels.
I would be interested in some info on your wind turbine. Do you have a web-site? Is the 10 kw the only size available?

For myself I would prefer a series of small turbines over one large one.
1) Easier installation, size of tower and weight of turbine. Can be raised and
brought down without using a crane or heavy machinery.

2) Capability to take one off line if it needs to be repaired without disrupting
all your energy production.

3) A smaller turbine usually produces less of a fluttering effect. The further
the turbine is from your loads or house the greater the loss of energy and
the higher the cost of wiring.


Looking forward to knowing more about the characteristics of your wind turbine,
Richard J

Hi Richard,

I know the Playa grande area well. I play golf there everytime I visit the DR.
The area has a wind class 4, which is a "good" wind sourse.
A very important factor is inspecting your "wind site". Visit:

www.windpower.dk/core.htm

click turbine sitting. Read all pages. This editorial will help you to decide
if a wind turbine is SUITABLE for your location.

Using multiple smaller turbines results in:
1. More wear & tear
2. More towers
3. More wires, transfer switches & misc connections.
4. More noise. Small rotors spin faster=increased fluttering!
5. Higher cost for overall kw production.
6. Aesthetically, your home will look like...well you know.
For small turbines "bergey" is the best. I located a few authorized
distributors in Santiago, DR. Go to www.bergey.com, click world distribution
and zoom into DR.
I suggest buying only the turbine. Given your elevation at 700 feet,
you can install a pivoting tubular metal tower approx 30 feet high. This tower
can be custom made locally having the "hinged" point 10 feet above
ground. Fix a counter weight at the bottom for easier erection. The reasons for this type of tower are:
1. Protect the turbine from hurricanes.
2. Easier inspection of components, lubrication and general maintenance.
3. Bring turbine to the ground when travelling abroad.
4. Replace rusting support wires.

My turbine design is based on large blades with slow rotation but high
torque. This design is less noisy, gives longer bearing life, is hurricane
proof and produces power even under a light breeze. Permanent magnet
generator is used with special design for low inertia-high efficiency.

Due to patent procedure, more info is not yet available, sorry.
Basically, three(3) models are tested:
a. 1kw for battery charging.
b. 10kw for stand alone.
c. 100kw for resorts.

Investing in windpower can be confusing and costly. Look at all products
out there before deciding how to go about it...Georgios.

Very interesting website...thanks
Georgios.

Up in the foothills north of Azua, where I live, wind conditions seem to be similar to those described by Richard. I've always felt my location is prime for a wind generation system. Georgios, please give me a ballpark estimate when considering a 1K, 10K system.
