In the middle of July I headed back to Nepal to have a holiday, catch up with some of my friends over there, try to learn a few more things about the actual implementation of pico and micro hydro and speak to people who now are electrified to see what they see the benefits are.
The first few days were taken up with rest. The previous 3 weeks had really taken it out of me, I was so tired but my mind was still working overdrive and sleeping was a real problem. The continual fly past from the mosquitos didn't help with sleep either. But after a few days I was relaxed and my sleep got better and better. I ate the Nepali staple food of daal bhaat twice a day, went for wanders around Patan where I was staying and watched some truly hideous Indian TV (so many talent shows and bad adverts - my favourite being the Bangur Cement advert when a little old man says Bangur Cement, similar to these).
I visited KAPEG again in Dhulikhel, who had been working with PEEDA (from my year out) on the low head pico hydro axial flow turbine project. They had redesigned the electronic load controller that allowed the voltage to drop below the reference voltage for a short time. This allowed motors to be started with the large inrush current they draw. This is a significant move for pico hydro controllers, as this will allow more industry to be used from the site, bringing cash into village communities. KAPEG had also installed a test site in Panauti, Kavre, where the turbine was installed beside a traditional Nepali pani ghatta, as originally envisioned by the designer. The site was installed next to a irrigation canal that was already constructed meaning that there was only minimal civil works needed. The site provided electricity to a school and a local chicken farm, and now could be used to drill, grind and cut material.

Alongside the work KAPEG had been doing, PEEDA had promoted the turbine unit all across South Asia. They had received orders from Bhutan and India, which showed the potential of the project. They had finished their one year project, so during my second week held a workshop to present all the work done with the turbine, from the beginning of the project. This project is very close to my heart, as it is the project that I worked on whilst at PEEDA, and had inspired me to do the PhD. I was very happy that PEEDA had finally managed to get some movement with it.

After the workshop I left Kathmandu for a 2 week tour around Nepal. I first headed back to Ilam to see what they thought now they had electricity. I had visited the village of Amchowk last year, where my friend Krishna Panthi was instructing them on the installation of a 28kW micro hydro unit. Now they had it, what did they do with it and what did they think? To get to Ilam was not an easy trip. Last year I flew to Bhadrapur, but this year I decided to take the bus as it was a lot cheaper - around £10 compared to over £100 for flying. The downside was that it took 2 days to reach Ilam Bazar, instead of the half day it would take flying, before another day's jeep ride and walk to Amchowk. As I had arrived in monsoon season, the roads were impassable in many places, forcing a 3 to 4 hour walk to reach the village. Krishna was no longer in Ilam, working in another district, so I went out to Amchowk with NCDC, a renewable energy NGO in Ilam who I also met last year. They were going to a site nearby to do a commissioning test, so I tagged along. In Amchowk, I met with some of the villagers and asked them what they thought the best thing was. They all answered the same thing, ujaalo - the brightness. Before they were dependent on kerosene lamps for light at night, with a few torches. Now, with the energy saving lightbulbs they could see so much better, and even with the 'zero watt' incandescent bulbs - used as they were 10 times cheaper than energy saving bulbs - the light was so much brighter than the kerosene lamps. Alongside the bulbs, people used the power for TVs, radios, mobile phone charging and the community had invested in 3 mills that they ran to process rice and maize. There was also a computer institute that ran classes for locals and a couple of people had their own computer too.

I also visited the village of Ekatappa which I had visited last year. They had recently finished their micro hydro system too, and had been running for about one month. As with Amchowk, they powered TVs, mobiles etc. It was interesting that in Ekatappa, as with Amchowk, when there was power, people ran their bulbs, charged their phones, even if it was bright outside. I supposed that this was the advantage of hydropower, the power is always there, you don't need to pay for more fuel to provide it, so you might as well use it whilst you can.

Ilam is the centre of the Nepali tea industry, and so in Ilam Bazar I went for a walk through the chiya bari - tea gardens. They are a most amazing place a very strange place to wander.

From Ilam, I headed to Lalbandi to see Didi and Bibek, who I spent a lot of time with during my year in Kathmandu. The road to Lalbandi passed by the Koshi river. 3 years ago the Koshi burst its banks and flooded across Nepal and India causing widespread devastation and loss of life (news reports from the time can be seen here). However, still in Nepal, the road across the Koshi had not been rebuilt fully, several sections still washed away and people's houses still temporary. I did wonder whether these people had been forgotten, once the initial emergency is over, how does life go back to how it was before? What has been done to prevent this happening again? Well, from the news I watched they still have been doing emergency work on the river dyke to ensure it remains firm, more firefighting than fixes though.

That's all for part one, there still more to come. Lalbandi - Pokhara - Gorkha then returning to Kathmandu for Janai Purnima!
