विद्यार्थीद्वारा वायुऊर्जा प्रविधिको परीक्षण

नेपाल समाचारपत्र (काठमाडौं) सरकारले वायुऊर्जाको अध्ययन अघि बढाएको बेला काठमाडौं इन्जिनियरिङ कलेज -कर्ेइसी) का विद्यार्थीले वायुऊर्जा प्रविधिको विकास गरी सफल परीक्षण गरेका छन्।

केइसीमा स्नातक तह दोस्रो वर्षा अध्ययनरत अमृतसिंह थापा, अमृतअवामणि ढकाल, पवन पौडेल, ललितसिंह रावल र सुरज र्राईको समूहले लामो अध्ययन गरेर यो प्रविधिको विकास गरेका हुन्। आफूले निर्माण गरेको वायुऊर्जा प्रविधिको मकवानपुरको फाखेलमा गत शनिबार सफलतापूवक परीक्षण गरेको समूहका अमृतसिंह थापाले जानकारी दिए।

यो वायुऊर्जा प्रविधिको निर्माणका लागि पाँच जना साथी मिलेर ३० हजार रुपियाँ जुटाएको थापाले बताए। २५ मिटर अग्लो सो ऊर्जा प्रविधिमा पंखाको उचाइ ५ फिट तथा डायमिटरको उचाइ १० फिट रहेको छ।

सो ऊर्जा प्रविधिबाट ३ दशमलव ५ प्रतिसेकेन्ड हावाको वेग तथा २ सय ५० आरपीएमबाट २ किलोवाटसम्म विद्युत् उत्पादन भएको उनले बताए। हालसम्म विकास गरिएको प्रविधिमा २ दशमलव ५ प्रतिसेकेन्ड हावाको वेगले मात्र पंखा घुम्ने गरेकोमा उनीहरूले विकास गरेको सो प्रविधिको पंखा शून्य दशमलव ५ मिटर प्रतिसेकेन्ड हावाको वेगमा घुम्न सक्ने परीक्षणबाट स्पष्ट भएको दाबी ती विद्यार्थीको छ।

करिब डेढ महिनाको लामो परीक्षणपश्चात् यो ऊर्जा प्रविधिको विकास गरेका हुन्। पंखा तथा जेनेरेटररोटको निर्माण नेपालमा हुने भएकाले वायुऊर्जा प्रविधिका लागि विदेशीको मुख ताक्नु नपर्ने भनाइ ती विद्यार्थीको छ।

केही हप्तापछि विद्यार्थीले पुनः प्रविधिको परीक्षण गर्ने भएका छन्। विद्यार्थीले पंखा सालको काठबाट निर्माण गरेका हुन्। सरकारले वायुऊर्जाको कार्यक्रम ल्याएकाले यसको विकासमा सहयोग गरेर यसका लागि नेपालमा आवश्यक पर्ने सबै प्रविधिको निर्माण गर्ने विद्यार्थीले दाबी गरेका छन्।

इन्जिनियरिङ विषय अध्ययन गरिरहेका विद्यार्थीहरूले थुप्रै प्रविधिको आविष्कार गरे पनि सरकारले सहयोग नगर्दा सो परीक्षण अलपत्र हुदै आएको छ। हालै पोखरामा पनि विमानको निर्माण गरी सफलतापर्ूवक परीक्षण भएको थियो। यसै गरी प्रविधिको सफल परीक्षण भएपछि ती विद्यार्थीले यो विषयमा थप अध्ययन गरी नेपालमा निर्माणको प्रयास गर्ने जानकारी दिएका छन्।

देशमा ऊर्जाको संकट बढ्दै गएपछि सरकारले चालू आर्थिक वर्षो बजेटमा काठमाडौं उपत्यकाबाट वायुऊर्जाबाट २० मेगावाट बिजुली उत्पादन गर्ने कार्यक्रम ल्याएको छ।

Student mission to tap wind energy
Kantipur Report
KATHMANDU, Jan 4 – Six students of an engineering college are on a mission to install a windmill.

The team comprising Amrit Singh Thapa, Amrit Abhamani Dhakal, Pawan Paudel and Lalit Singh Rawal from the Kathmandu Engineering College has built a three-blade turbine that can generate 2 KW of electricity when the turbine starts rotating at the speed of 300 run per minute (rpm).

Team member Amrit Singh Thapa says they have accomplished the most difficult task involving the project — the development of a wind blade that starts rotating when wind velocity is 0.4 to 0.6 m/s.

Recently, the students tested three wind blades at Phakhel VDC of Makwanpur district.

According to Thapa, the turbine can generate 1.5 KW when the maximum speed of the blades is 300 rpm.

“Power thus generated can meet energy requirement of at least nine households,” says Thapa. “This method is also cost-effective.” According to him, around Rs 100,000 is needed to set up their kind of windmill. The students are also busy developing generator and other essential equipment. “But we have been facing resource crunch,” Thapa says.

The students are going from pillar to post to collect funds and accomplish their mission, but have not got much-needed help from any quarter, including the government.

They say they have already spent Rs 30,000 for the development of wind turbine.

“The government needs to tap energy to mitigate the energy crisis,” says Thapa. It may be recalled that the government aims to generate 20 MW by installing windmills this year.

The students say it will be difficult to achieve the goal because the government is not serious about harnessing wind energy.

Wind turbines are more reliable than other sources of power and can generate electricity 99 percent of the time in comparison to other sources.
