Green Shade Net completed atlast !

After a lot of persuasion, waiting and followup,  a simple Shade for Nursary plants have been created.  Hope we can grow vegetable seeds underneath once we buy polythene bags.

Shadenet is ready
Started by procuring the shade net clothing through phone and getting it couriered to the farm from  a coimbatore supplier.  It cost Rs. 2100 for a 4.2 meters x 50 meters bundle (10 feet x 160 feet).
Inside the Shade net.  The floor has to be raisen in future.
Presently by blocking the gaps with mud, the purpose is done.
we need to purchase polythene bags for growing

Then it was pending for festival, sick holidays etc..  Finally yesterday the required poles  (casurina) was purchased and a large shade area of 25 feet x 15 feet created in one shot.   The poles were anchored on the mud and for strength additional poles were tied in cross fashion.  2 feet into the ground, two feet above the pandal.  Local design. Just serving the purpose. I got the photos mailed yesterday to me. I was surprised to see the chosen place. I thought of another place. This generally happens for remote execution. We need to further improve on the communication.  Anyway, good job done by my local team.

Ideally I did not want to cover all the sides, but team had done a brilliant job of half covering.  This is required to stop the warm air at ground level for nursary plants, at the same time providing transparancy and air circulation above hip level.

Objective is realised.

The First Anemometer readings - wind speed measurement on Farm.

Now the Anemometer is working fine. Subbu discovered a small switch that had disengaged the meter. Now it is working fine after it was pushed back. Subbu and team  made an easy ladder path to climb up the tripod pole made out of Casurina poles connected with wooden steps and plank, at a height of 19 feet and says he enjoys staying over there.  Cool. 

The below are the anemometer readings that have been received from him.  The anemometer has counter measuring in xxxxx.yy where x is in kilometer and y in meters. He said he was waiting or y counter to come to zero before noting down. Then I corrected him and asked him to give two digit decimals also as it is without waiting unnecessarily.  Otherise they will become nervous. First three columns are inputs. Balance are calculated by me over excel sheet.

I am not sure if I have done the calculations correctly. But common sense is saying it is reasonable. As per this measurement I am getting a wind speed comfortably above average.  3 Meters/sec is considered slow and 4 Meters/Sec is considered medium speed.  Surprisingly the internet is not having any information regarding the actual field measurements made in our part of country (or for that matter anywhere else) inspite of the fact that there is so much of hue and cry about wind energy and crores are being invested in.

The good news is that these speeds are at 19 feet height / 6 meters.  The actual windpump rotor if purchased will be at 15 meters height.

Another finding is that speeds at day time is high and night speeds are bit low. I cannot conclude anything now, but need to watch for atleast next 30 days before taking a big decision - wheather to buy a windmill or not..
