                                                Water mill is one of the traditional kind of grinding wheel that uses wheel or turbine to drive a mechanical process for various end use such as flour grinding,lumber or textile production.This type of technology is applicable in hill areas where there is enough head for running turbine. The water diverted from river or canal provides enough kinetic energy to drive wheel or turbine via head race channel or pipe.The force of the water’s movement drives the blades of a wheel or turbine, which in turn rotates an axle that drives the mill’s other machinery.

                                          Water leaving the wheel or turbine is drained through a tail race, but this channel may also be the head race of yet another wheel, turbine or mill.This kinda of water mill is suitable in hilly and Himalayan region of Nepal where enough head is available.Not only for milling but it can generate electricity which can empower local community which can contribute for decreasing load on central load distribution.

                           This is good example of use of appropriate technology helping people to live under light. The micro-hydro generates electricity to operate mill services for customer and provides power in night to local resident in vicinity. 

Solar Training and Capacity Building : Power to the People

DSCN2369

                                    March 29, 2016 Before dawn of warm and fuzzy morning I woke with sharp shrill of mobile alarm at 5:00 am. As it was planned to meet at 5:45 am at Old Bus Park to move into another adventurous travel on off load leading to Dhunkharka, Kavre. The bus ride from Old bus park took us to Panauti via Bhaktapur, Sangha, Banepa. The real journey began from here accompanied by Mr. Subash Lamichane and Mr. Kancha Tamang. The 14km dusty, bumpy, narrow and scary road begun from Panauti steadily uphill climb in bus cramped with people, animals (chickens), kids crying, people yelling at each other. It was perfect like Hindi film melodrama at bus. Irony was that we were not able to get any seat through out two hours ride. Even within bus we had to wear mask and continuous shake up really made me tired. But internal motivation to go there and help people to sort things out, teach them, connect them to more reliable energy was continuously pushing me up.

                                        After travel of 2 hours we reached Dhunkharka. The bus stop was on top of hill to reach to our destination we had to go downhill and again uphill. The slow down hill walk began interacting with each other knowing about peculiar things about location. It was good to be back on hills among tress, clam and serene country side where nothing bothers you except cool breeze, birds chirp and perennial flow of river. I encountered various rural technology like water mill, hydraulic ramjet pump, fodder cutting machine, solar system. The very delicious meal was waiting for us, prepared from organic vegetables, grains crushed from water mills, cooked in improved cooking stove, rice grown in nearby fields. This was perfect amalgamation of technology with rural livelihood.

                       The training sessions began at 11:00 am. The 22 owners of solar system were present in upper floor of cowshed. It was great to see energy and enthusiasm in people. The training started with introduction of speakers and participants. The training was planned for 2 hours and following topics were discussed:

  • The initial session explained about what is renewable energy, Solar as renewable energy.

  • Participants were introduced about solar system and its components like Panel, Battery, Charge Controller and Load.

  • Installation do how and safety handling was demonstrated with system present on the location.

  • Various Procedure for Repair and Maintenance were provided.

  • Specific care handling, minor damage and quick repair locally was provided about battery, charge controller and loads.

  • Final solar power use calculation was done and how much load people can use with technology given to them was shown.

Training Outcomes

                          The people have been following malpractice about solar system handling. The solar panel were hung as photo frame in walls, no safety precaution were taken, people were brining in & out panels in rains, their perception was heat generated more power than light. About training accomplishment participants got chance to learn about each components of solar system. They are now able to assemble and dis-assemble the system on their own. The standard parameters like facing panels on south direction, keeping panels at 30/45 degrees, keeping battery far from heat source, use of loads according to power generation, sustainability of battery system, various light symbols and their meanings present on charge controller, minor repairs was provided. Overall looking after longevity of solar system with efficient use was provided.

                  After completion of training we visited two hydraulic pump operation at Chanaute and Ladkhu. We learned about bio-char preparation, its use.

                           The return was one of the most memorable journey of my life. The last seat of bus squeezed between a women with child and old grand pa. The lady by side was vomiting throughout journey while grand pa was drunk, mumbling and fumbling with words and directions. The smell from both side was killing me, as I sat contemplating about life. I endured situation, just invigorated into circumstance.

                                              This was one of my life awakening journey. What surprised me was humbleness and subtlety of people. Obviously they are cutoff from mainstream media attention still they are happy to be living there. There are numerous challenges but somehow they have managed to be living well. I hope to see better road access, sustainable clean energy supply, educational facilities, better health facilities and access to ICT be within their reach. The natural serenity shall not be disturbed, only right technology along with nature can develop Dhunkharkha.

Pani Ghatta : A Grinding Machine

                       Water mill is one of the clean and appropriate technology for grinding at local level. The most of part of Nepal still remains far from electric grid connection. The rural electrification has been catch word just to remain safely in vaults of Planning commissions.. Nepal faces one of the longest hour of blackouts as energy crunch nation we are struggling with basic right to energy access. The geographical terrain, improper settlements of housing system, challenges of hindrances on scenic beauty and landscape as tourism being one of major attraction, losses on transmission lines might be counter acting such kinda of electrification initiative.

                       The appropriate technology is recognizing need of local people, meeting their aspirations and bringing them one step closer to energy access. There is flow of water from higher hills to lower plains. Here gravity does most of the work. The Kinetic energy of water can be directly used for generating energy. Traditionally we have been harnessing such energy through water mill. Still today lots of people in rural areas are highly dependent on traditional water mill for grinding all required household goods such as flour, rice, wheat, spices and also oil in some cases.

Working Mechanism:

                       The water from head of 20m or above is brought in open or closed conduit. Traditionally wooden blades are used as turbine on which water jets are strike upon, jets rotates the bigger wheel mounted on smaller wheel. There is continuos feed of grains in between grinds into finer particles.

A story form DhunKharkha, Kavre

                           The village has perennial source of water, water mill is located near river close to the source of water. The villagers have been using water mill for grinding their grains. It was happy to encounter old mother who was grinding her maize on mill. She was so delighted to use it, as it has reduced efforts and time that people used to devote for grinding in traditional way. She explained although she is weak and fragile, she can help her family in some way. The use of water mill popularly known as pani ghatta is free to use. The opening and closing is as simple with supplying and cutting off water supply to mill. She is happy and proud user of water mill.

                                 This is what appropriate and proper technology can transform rural life. Helps in bridging gap in energy and technology use.

Journey form Training to Trainer : As Light of Hope Continues

                      Energy has been one of the basic requirement of human beings. The traditional use of fossil fuel is gradually shifting with advent of cleaner and greener technology. And change in people perception and consciousness about climate impacts, global warming and green house effects. RAN (Robotics Association Nepal) is one of Nepal’s best institutions trying to promote technology for generating holistic relation between machine and human.

                             The #LIGHTOFHOPE is audacious project initiated by RAN with agenda to connect rural livelihood to basic energy use like lighting and charging system. The process is to connect rural and earthquake affected area to primary energy use. The deprivation of energy & energy crunch is not only hampering economic activities but education of students. So #lightofhope aims to bring back hope to people to re-start life. Everything is broken but there stands only hope that things will get better. #LightofHope tires to embolden resilience, empathy and provide strength to return to normal living for Nepalese people who are beyond electric grid connection.

                                The Shree Nawalpur Secondary School was place for solar training and distribution. The place being in vicinity of Melamchi, still lacked proper road and electric connection. The event was already planned and well arranged by local partner YUWA Nepal. Primary task was to train ninety student, equip them for repair & maintenance, and distribute 5W solar system with light and charging system. We could see curious, energetic and bold ninety students, school authority, local experts being in school. We were really glad despite public holiday of Saturday people were kind enough to show up. The main objective was to give introduction about renewable energy, detail about solar system, component of solar system, repair & maintenance and about how solar can good business opportunity.

                                      Personally there is great difference in being with the crowd and handling the crowd. Being in training helped me to learn and nurture self. I was always obliged and felt privileged to get such opportunities. This was time to pay back or simply spread good vibes for others. I tried as much as being basic about facts and in mean time holistic. The major point I was careful not to let voids between by talks and student listening. The sessions was quite interactive, reaching student asking them and they asking back their queries. I was able to reach their psyche to some extent inspire them to lead from grass root. It was amazing to teach, hear, learn and share among students. The latter solar as business opportunities was carried out by Binod Pangeni. This session was especially designed to promote business opportunities that can or comes with solar technology. The main idea behind this was to encourage student to find solution within country and to remind them there are possibilities as well as potentialities developing country and making money in Nepal.

                                                    The journey to and fro Sindhupalchowk was full of fun. It was great conversation with fellow travelers local resident Aunt who rose my curiosity about place, her experience after earthquake, how grateful she was to have young people like us helping them, the hardship they have been through, hope & resilience they had despite their homes were completely turned down, her future dream to rebuilt house. Thanks to volunteers from Australia and Germany for being here selflessly to be part of re-construction. It was great to catch up with you guys. Oh! Driver dai, your story and reasoning and loud music system made us inexhaustible throughout travel. It simply helped us to be cheerful. Many many thanks to Bikash Gurung dai for providing wonderful opportunity to actually go to different part and shade some knowledge I had. It was great to reach people in local level and empower them. #LightofHope continues for adding hope for rural livelihood and re-construction after earthquake, shading light raising people’s aspiration.

Cheers.
