Trying with Wind

It is always pleasing to start a new prospective in some proven technologies. We believe it is how we can make relevant changes and make product competitive and less expensive for consumers. Recently surfing through SWERA report, we found a new project to talk about with our energy enthusiast. Its wind power for Nepal.

Though Nepal has many companies dedicated towards wind energy as Krishna Grill and Engineering Workshop (KGEW), Kathmandu Alternative Power and Energy Group (KAPEG), yet they are not able to produce much. It might be due to less research in the sector, unwillingness to pay by consumer, failed example of Kagbeni, but most common is definitely the cost of Wind Power system. With some of Youtube experience it was found that it is not that hard to start up a Wind Plant with low cost but it will take few days to make one.

The PVC turbines as seen in various literature can surely be an alternative for the commercial blades. Though lot of efficiency is under stake but we can make the thing moving merely with few hundred Neplese Rupees. Properly designed blades can do really good. A brief idea of making blades is shown in the figure below.

We pretty much followed the template above. After the blades were nearly in shape with a small hub to give 3 blade arrangement we were ready to go. With the help of good friends and good wind the testing was carried out. Few glimpse of initial testing is shown in video below.

After the good rotations and few measurements we are now running up some more ideas of Alternator and Stands. Another video showing few more upgradations is shown below. 

Hope we will come out with very good solution for remote village in Nepal. Hope so.....
