Pani Ghatta – Water Mills

PPvQVzQ                 

               Himalaya are boon and curse. These are the mountains that’s helps to tranquil our soul and assemble our hopes in solitude. The same mountains stand tall to hinder the progress to modern development and technology. The mighty rivers starts as rivulet in lap of these mountains. The kinetic energy of falling river among the slopes are used to harness power to grind grains to empower human body. The conservation of energy works perfectly fine satisfying scientific society of rich nation who want’s to keep nature pure and make big shout out for being agrarian while doing so.  

              These turning machine are popularly known as Pani Ghatta a.k.a water mills. The water mills are very popular across Himalayas, as it is only reliable machine to grind grain for people living across the regions. The water mills is not limited to Nepal but you can see across stretch of hills of Afghanistan, Pakistan, Tibet, and Bhutan. Traditionally limited to grinding, now many are modified to generate electricity for local use.

Construction:

          The water is diverted from the main stream via open or closed duct towards the turbine placed on lower section of mill house. The turbine used to be made of wood, but majority of wooden turbines are replaced with metallic as improved water mills these days. The vertical shaft connected to turbine on the floor of mill house runs, and turns the upper section of stone. The lower section is stationary, and grains stored in wooden settings above the stone drops grains through hole in upper stone to lower stone via feeder mechanism, and then grains are grinded in between the stones.

Improved Water Mills (IMW)- New Name for Modern era

                         Improved water mills is one of the clean technologies promoted by government of Nepal with many other stakeholders. Nepal has about 25,000 traditional water mills scattered throughout the country. 6,500 of them already have been converted to IMW. Replacement of wooden parts (rotor and shaft) with metallic parts is the main improvement made in the technology. The technology can also generate electricity up to 3 kW, sufficient for lighting as well as for operating small electric and electronic home appliances.

Advantages of IWM

Employment :The installation, advocacy, operation, maintenance and promotion of IMW will create lot of opportunities at national and local level employing skilled as well as unskilled labor.

Income Level :It helps to improve income of mill owner as well as user. It helps to increase living standard of local people.

Boosting the local Economy : The water mill will remove drudgery of traditional grinding. It will save time which people can invest in income generating activities like animal husbandry, agriculture, and others. People will get familiar to new technology and electronic devices which is powered by electricity from water mill.

Gender Mainstreaming and Social Inclusion: Water mills helps to reduce stress of grinding grains for women. Traditionally grinding was done manually by women. This replaces huge burden on women. The mills will be melting point for women to socialize and get connected to each other. It helps to remove social evils like un-touch-ability, status quo and others.  

Environmental Impacts :The IWM is powered by gravity-driven water, a renewable source of energy, which essentially does not produce air pollution or sound pollution. Therefore, the technology is environmentally sound and acceptable.

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.
