Re [Green-India] Re: New micro wind turbine developed for household use

[chan...@sancharnet.in]

Wind data shows that Alibaag is hopeless for wind generator installation.

Do not fall in trap for the wind generators that work on low speed like 2m/sec. Remember well that wind power is proportional to cube of velocity. Hence if a wind machine is designed to deliver 1000 watts at 12 m/sec, the same machine will generate only 5 watts if the wind speed falls down to 2 m/sec. If there is no power in the wind what can you get out of it?

Regards,

Prof. Ajay Chandak.

Dear Mr.Jayesh,

Micor windmills working with starting wind speed of 2m/s are available now a
days.Following are geographic details of your location.

Latitude (DMS) 18° 38' 28N Longitude (DMS) 72° 52' 45E Altitude (meters

Also enclosed please find wind speed data at your location.

I have also enclosed Daily Load Calculation sheet and to guide you, I have
filled with some date but actual data to be filled by you, so as correct
system can be recommended.

Once I receive response, will let you know the costing and feasibility.But
to tell you as a thumb rule, wind power will cost 50% less than solar power.

Also wind power system to be coupled with small solar PV system as wind
speed is not uniform throughout the year.

In case of any difficulty to fill data,etc please call me at 0-92464-75056
and I will be very glad to help you.

Looking forward for your +ve response.

Hello,

I tend to agree with the Prof. There are enough data points on the
measurements done on existing residential windpower systems that prove
this fact.

You can refer to Warwickshire Wind Trials wherein they have collected
measurements over a period of a year. In an extreme case, the windmill
was taking more power than it was generating. I think there is a similar
trial done in NZ as well.

I would hazard to say, unless there is a natural physical phenomena
wherein due to tunnel effect you get a lot of wind, you are looking at a
very bad ROI.
In any case, please see if you can get a reading of the avg windspeed
in your house by measuring it yourself or asking someone who resides in
the neighbourhood. Also check if you can get someone to give you a
measurement of the power output from the installed windmill.

Cheers,
Raghavendra Rao [rags]

Dear Prof. Chandak, I totally agree with your approach. We should follow the basics. However, may be with some technological innovations such as Contra Rotating Turbines the generation may increase ?

Dear Prof. Chandak & Mr. Rao,

 

Thank you very much for your timely insight. I will first get proper wind data before proceeding further.

Dear Mr.Jayesh,

 

If we can prove that at 2m/s, our wind mill can generate more than 5W,what will Mr.Ajay Chandak do?

 

His language is not professional and he is not aware about the best quality wind mills available as on date.

 

I can even show installations and you can feel free to discuss with existing satisfied customers and then take your decision. I will never advice and dupe as unless and until I strongly believe and get convinced myself, I will never venture into recommending.

 

Decision is yours as you are the customer.Its like this in a nutshell:A cheap quality CFL lamp may be less expensive and fail but a good quality oof equal wattage may even come with 1year warranty and this is how CFL industry also faced initial problems and in small wind mills also some failures are there and the one what I am talking is designed by a professional who has done PhD in wind energy technology.

 

Looking forward to hear from your end.
