Markets, TLUDs, and Peanuts

Hello friends back home! Though we are quickly nearing the end of our time here in Tanzania, work with the partners has been keeping us just as busy as ever. With just one more week left on the trip itinerary, we are scurrying back and forth every day to ensure that each group is in a good place briquetting-wise before our departure March 8th. Continuing on from the last blog post, we’ve attended another market session with the women’s group at EMORG, returned to Bernard’s shop to make adjustments to the small-scale demonstration TLUD carbonizer, and observed another pressing session with Violet Ayoub at the Vision for Youth production site.

On Wednesday, Sammie and I took our second trip to the weekly Kisongo marketplace near EMORG, where the chairwoman and two other members were continuing to market their charcoal briquettes. Despite not having purchased one of the traditional counter-weight massing scales yet for the group, we were still willing to lend our digital electronic scale for selling purposes. However, the women were adamant that this would dissuade customers and hurt sales since the latter was more foreign and less trusted. Instead, to our pleasant surprise, the chairwoman whipped out a spare scale from her storage just like the one on display in her shop. With equipment in tow, we took the 5 minute walk to the marketplace and set the supplies on an unoccupied patch of the market across from the lump charcoal sellers. Once there, the briquettes generated a lot of attention; waves of 4-6 people at a time would come and talk to the women enthusiastically about the manufacturing process. In between waves, two women took turns taking a sample of 5 briquettes in their hands and walking through the marketplace looking for potential customers. Despite the hullabaloo, only a few people actually purchased the briquettes, which were being sold again at 1,000 TSH per kg. Curious, we asked one of the lump charcoal vendors nearby if I could determine the mass of the two bucket offerings of charcoal available (instead of a mass basis, lump charcoal is traditionally sold in buckets). What we found was that a small bucket (containing about 1.8 kg of charcoal) was selling for around 800 TSH per kg, while the large bucket (containing about 7 kg of charcoal) was selling for around 700 TSH per kg. According to work done by the Legacy Foundation, briquettes should be priced below other competing fuels like charcoal to assuage the novelty and uncertainty factor associated with an unknown product, which didn’t bode well with the women’s current marketing strategy. At the end of an hour and a half when the women decided to pack up for the day, they had sold 6 kg of briquettes. Since the women can generally produce ~9 kg of briquettes per week at an average cost of ~600 TSH per kg, it may be worth investigating whether they can decrease the price to sell at least a week’s production each time they visit.

On Thursday, Anna and I went back to Bernard’s shop to further modify the small TLUD carbonizer based on the feedback from our initial burn. Adjustments included adding a separate afterburner piece with the mixing tabs pioneered by previous iterations of the loose biomass stove to provide more secondary air, knocking off the stove legs to allow the stove bottom to rest firmly on the ground to cut off primary air during the quenching phase, and using a piece of sheet metal as a lid to cover the top of the kiln and exclude air entering there during the quenching phase. After confirming the 5:1 ratio of cross-sectional area devoted to entering secondary air and primary air, we also decided to block half of the primary air holes with mud during actual operation. Our second run with dried sticks and kindling leaves proved more successful, burning more cleanly during the active phase and with a longer duration. However, when we transitioned to the quenching phase, we noticed that our lid was not appropriately air tight, so a lot of gas was escaping through the top and making the surrounding environment particularly unpleasant. After a 20 minute anaerobic period, we quenched the system with water and observed the yield. Many of the sticks that we had collected initially were of variable size, and in particular, cross sectional area. Consequently, while many of the thinner sticks were carbonized all the way through, the thicker sticks were only carbonized on the surface while the woody innards were merely torrified. Although a full scale operation should focus on carbonizing loose biomass, current experimentation has highlighted the importance of making the initial feedstock as uniform in composition as possible.

Finally on Friday, Peter and I took a trip to visit the Vision for Youth briquetting site, where we met with Violet Ayoub and three of the other members. To start, we talked about the BLSD kiln that was still running from when they loaded it 24 hours prior. They observed that the kiln was now taking longer than a day to carbonize a batch of material, and the material inside was turning into ash near the primary air holes and remaining uncarbonized over the secondary air channel. Violet recognized that the ash production was a necessary consequence of the partial air injection that is required to fuel initial combustion; however, the asymmetrical distribution of heat is proving to be a significant challenge both in terms of material conversion and operating time. After resealing the kiln, Peter talked to Violet about the small-scale TLUD that DHE has currently been investigating based on the larger oil-drum TLUDs pushed by ARTI in Dar es Salaam. We also got to observe another briquetting session with Violet. We watched the sifting process, which went relatively quickly since grinding wasn’t necessary for the torrified sawdust. The Vision for Youth team also experimented with wheat flour in their binder porridge, which worked reasonably well. With Violet leading the mixing, the slurry was also less binder-heavy than before. Pressing still proved somewhat awkward with the unusual way that material was loaded into the molds; however, we anticipate that the EMORG women’s group will have a lot to share in this regard as collaboration continues to develop. On a side note, we also enjoyed an amusing, mutual misunderstanding at one point. Violet in particular was excited about the prospect of using “groundnut” husk as a feedstock for the kiln because it is not usually fed to livestock. However, we had no idea what groundnut was, and took our fair attempts at guessing. Not walnut, not cashew, not pistachio. It was only after being shown a picture that we realized that they were talking about the peanut. It just goes to show that biomass by any other name burns just the same.

With only a week and a half left here in Arusha, we are moving into the final stretch of the trip. We’re working hard, trying to accomplish everything we want to in the limited time that we have left! The rainy season has abated, and we’ve been enjoying five days of dry roads and sunshine.

On Saturday we visited EMORG to do a session on briquette pressing. We were very impressed by the efficiency of their operation—they speedily pressed out over 200 briquettes! We are helping them to look for a permanent scale that they can use to sell them, and will be returning with them to the market today. Good weather allowing, we should be able to observe the market for longer than we have previously.

Sammie, Frank and I headed out to visit our partner Lulu Vicoba on Monday. It was exciting to be able to see all of the briquettes that they’re making! They showed us the presses and molds that they are using, and demonstrated the traditional three-stone stove for us. They also showed us models of traditional Meru housing, noting that it is difficult for smoke to escape from them because they do not have windows or chimneys. This makes it really important for there to be access to smokeless cook-fuels.

Frank was able to gather many important values on Lulu Vicoba’s briquetting process, and is using them to conduct an economic analysis on their operation. Sammie collected some briquetting anecdotes, overcoming the language barrier with the help of a translator. We also gave three posters on briquetting to Lulu Vicoba. They seemed very excited about them, and eagerly promised to hang them on the walls of their office.
We’d like to thank Didas of EMORG for helping us to find a driver to get us to Lulu Vicoba’s meeting space, and Naomi of EARD-CI for finding our translator.

Yesterday Frank and I trekked out to Njiro to go to Bernard’s workshop. There are still some relics from past DHE trips here, including some rocket stove prototypes! We modified one of the old rocket stoves into a small top lit updraft kiln. It is the largest TLUD that we have made. Initial test burns have been promising, but we are planning to return to the work shop tomorrow to make some additional modifications.

Kwaheri!

Travel Team Keeps Grinding Away

Wow only 2 weeks left here in Arusha for the travel team! Big things are happening on the regular, and we have a couple things in particular that have happened since Sammie’s last post.

With the help of our friend Bernard and some skillful hands at his workshop, we finished the first prototype of a new charcoal grinder on Wednesday! While it still has room for improvement, it’s a big step toward relieving the women of the back-breaking work of grinding the charcoal with a mortar and pestle. We brought it to both Vision for Youth and EMORG on Thursday, and they were both grateful for its potential to improve the process. EMORG had a carpenter look at the design today and they should have a bigger version of it soon!

The excitement didn’t stop at the grinder for EMORG and Vision for Youth, though. Yesterday we got the leaders of the two groups to meet for the first time – the first of many we hope! Since we’re only here for another 2 weeks, it’s crucial that knowledge on briquetting can continue to be spread in Arusha after we leave. It’s exciting to see the different briquetting groups start to network in ways that will be mutually beneficial moving forward. The meeting went so well that EMORG invited the Vision for Youth leaders out to their workspace to see how their briquetting operation works. The meeting was in Swahili so we couldn’t understand much (Violet Ayoub from V4Y filled us in on the important things), but at the end I heard an enthusiastic “Karibuni” (welcome) several times from the EMORG chairwomen – always a good sign.

First meeting with Vision for Youth and EMORG together!

As for lifestyle updates, I’m basically a local now because I had to ride on the outside of a dala dala the other day – hanging on for dear life. It was a little scary especially because there was so much mud, but at least I had way more space for my head and knees than I usually do on the dala dalas! We’ve enjoyed making friends with the locals as well. Some highlights include the girls politely turning down a few marriage proposals and I got to teach some new friends how to throw a frisbee.

That’s all for now, but stay tuned!

Halfway Point!

We are now two and a half weeks into our trip, and thankfully spirits are still high!   It’s been a while since our last blog post (sorry!) and a lot has happened, including two birthdays and a good amount of progress.  We have now had meetings with EMORG, Upendo and have a meeting with Lulu VICOBA tomorrow.

The women’s group at EMORG is doing great work with their briquetting operation.  We have seen a charcoal processing session as well as their final products.  Their briquettes are beautiful and they are able to make them in fairly large quantities (about 400 per week).  We have noticed, though, that the grinding process has been very labor intensive.  They are using a mortar and pestle and it takes about two hours to process their charcoal.  Peter and I tried it out, and it’s pretty hard work (I can’t imagine doing it for two hours!).  They’ve said that a machine would make their charcoal grinding easier and more efficient, so Frank and Peter are working on creating a processing machine for them (as well as for other groups, hopefully).  We will be working with AISE’s founder, Bernard, on this project.

The other exciting news about the women’s group at EMORG is that we went to the market with them and they sold briquettes! They have been making briquettes for a long time, but have not been selling them at the market.  Unfortunately, we were only able to stay for about 15 minutes before the downpour of rain came and ended our market day.  We were able to sell some, though, and that was very encouraging.  It’s great for the women’s group to have briquette-based income so that there are tangible benefits for all of their hard work.

Vision for Youth has also shown promising progress in their briquetting operations.  Anna and I have observed their entire process now and are excited about their continued progress as we work together to increase efficiency.  We are also trying to arrange meetings between Vision for Youth and our other partners.  One of our big goals is to connect these groups together in a way that is beneficial to them, and so we are trying to set up initial meetings.  They all seem very excited to meet with each other and share ideas.

Initial meeting with UPENDO

We met once with Upendo and enjoyed seeing their space, it was very beautiful.  Unfortunately, due to conflicts, we will not be able to meet with them again until early March.  We hope, at that point, that we are able to connect them with our other partners before we have to say goodbye to Tanzania.

On a more recreational note, we spent last Saturday in Moshi at the hot springs.  They were relaxing and a great break for a day. We swam, ate chipsi mayai, and made some friends!

The Boys Venture to Dar es Salaam

Jambo friends!

Peter and I traveled to Dar es Salaam this past Tuesday, February 4th. After an hour long taxi ride, we became well acquainted with the city’s traffic-jammed streets filled with vendors weaving between trapped vehicles and peddling everything from peanuts to giant stuffed animals to the unhappy drivers. Eventually, we made it to the Safari Inn, where we established basecamp (and enjoyed the luxury of consistent air conditioning!) for the next three days.

The next day, we got up bright and early to catch our taxi to the University of Dar to meet Dr. Rajabu, a senior lecturer in the energy engineering department and longtime collaborator with DHE since the rocket stove project. There, we also got to meet Christian “Rui” Lohri, a researcher from the Swiss Federal Institute of Aquatic Science and Technology, who was serving as a co-advisor for two of Dr. Rajabu’s master students, Adam and Elia.  Despite struggling to find the Engineering College (our taxi driver, Salim, had to ask the local residents for directions), we arrived just in time to sit in on their weekly project meeting.

For their master’s work, both students are focused on developing low-cost processors for the drying and carbonization steps of converting waste biomass into charcoal. Adam’s project is a solar powered biomass dryer that uses a solar collector to heat air being drawn through a drying rack by an electric-powered fan. The solar collector also has an insert for a charcoal stove so that air can be heated during cloudy days. Elia’s project is a carbonizer made of a brick and a rotatable oil drum. Basically the rotating mechanism makes the process more efficient by using the produced pyrolysis gases to make the process self-sustaining.

After the project meeting, we had a quick lunch before we hopped into Dr. Rajabu’s car to take a bumpy road trip through Dar’s mountainous back-roads to visit several of the briquetting sites in the city. The first was a technology farm run by Tatedo (Tanzania Traditional Energy Development and Environment Organization) showcasing several batch carbonizers including dirt mounds and large scale brick-and-oil drum retorts, greenhouse biomass driers, and motorized briquetting processors such as a briquette extruder, and “pillow case” briquette press. Afterwards, we stopped by ARTI (Appropriate Rural Technology Institute) Energy’s Tanzania headquarters, where we got to see their oil drum TLUD carbonizers (essentially big scale versions of the demonstration TLUD on campus), and their hand-powered briquette extruders. To top off the visit, we talked with the executive director, Nachiket W. Potnis, and one of the program officers about their business model. ARTI expects to produce and sell 4000 tons of charcoal by the end of the year! It’s exciting to see at these places how charcoal briquetting can be successful and make an impact at a large scale.

Hujambo from Arusha!

It’s hard to believe that we have only been here in Arusha for three days! The travel team has been keeping very busy. We are picking up some Swahili, and enjoying the heat after Hanover winter. Everyone here is incredibly welcoming and friendly, and we hear “Karibu!” (welcome) everywhere that we go. And the food! I could rant about how amazing the food is for several days. We have a wonderful cook, Nema, who is teaching us about Tanzanian cuisine and Swahili.

Peter and Frank left for Dar es Salaam on Monday. They met with Dr. Rajabu today, and will return on Friday.  Before they left, we had the pleasure of meeting with Miss Ayoub, Violet, and Veda from Vision for Youth. It was wonderful to finally meet everyone after hearing so much about them from the summer team!

Vision for Youth Meeting

Sammie and I were able to meet with Vision for Youth again on Tuesday to observe a burn in their brick kiln. The travel team is using initial meetings with our partners to see what progress they have made since the summer team visited, and we were very impressed with the operation that Vision for Youth has set up. Their knowledge, skill, and ideas for the future were tremendous, and we greatly look forward to working with them further. We plan to meet with them again on Friday, to review posters that the travel team brought with us and meet the rest of their briquetting team.

DSCF0858

We are excited to meet with the women’s group at EMORG tomorrow! Didas and Troy at EMORG have been extremely kind to us, and we are delighted to be able to finally see EMORG and meet the briquetters. We also look forward to meeting with Upendo on Saturday.

I think that’s all for now, and we will update again soon! Kwaheri!

Meet the 14W Travel Team

The 14W Tanzania Travel Team has been working together since October 2013 and has done a lot to get to this point.  We are all so excited to have the opportunity to travel to Tanzania to continue the work on DHE’s Bioenergy project.  While in Tanzania, we hope to help share information with our partners while simultaneously learning from them.  We also plan to help establish connections between our different partners in order to form a briquetting association and support network.  Finally, we hope to be able to interview and speak with our partners in order to learn and measure the impact that DHE has had in the Arusha region.  Past travel teams have done great work before us, and we hope to help the project progress even further.

Our team is so excited for this trip and we hope to reflect that in this blog.  We will be writing about our work in Arusha as well as our adventures, the people we meet, the places we see and of course, the many things that we will learn!

Namaste from Nepal!

After swerving through a jumble of motorbikes and pedestrians in one exhilarating taxi ride, I arrived at Adi’s house tucked in a peaceful side road of Kathmandu. Chad joined us soon after, and we celebrated the reunion with a scrumptious BBQ of chicken burgers (cows are holy). We sat under the starry sky and chatted with Adi’s father and younger brother, while his mother brought hot cups of tea that warmed us from the inside out. Such lovely hosts!

 

I woke up the next morning to the sound of roosters crowing across the street and dogs barking for them to shut their beaks. Team SafaPani was up and ready to get to work! We started out through the village, passing uniformed schoolchildren with the most adorable, cheeky smiles, and made our way to a taxi that carried us to Thamel – the bustling tourist center of Kathmandu. Adi brought us to one of his favorite coffee shops set in a former summer palace for royalty. Properly caffeinated, we powered through two hours of peak productivity.

Getting down to business!

Our main priority was to schedule meetings with water experts and NGOs, with whom we met over the next few days. The information and contacts they provided were invaluable. Here is a summary of what we learned:

 

VillageTech Solutions: Wouter (Dartmouth ’14 and DHE project leader) and Maria gave us insightful tips on how to approach and interact with NGOs in Nepal. Being culturally sensitive and phrasing projects as collaborations rather than impositions is key. The VillageTech team also came up with some great ideas to help us market the system, such as establishing networks for disseminating information through trusted doctors and educators.

Advice from the VillageTech team in Kathmandu.
Breakfast with the VillageTech team in Kathmandu.

 

Water Engineering & Training Center: Bhola Paudyal gave us a fascinating tour of the chemical processing machinery that provide precise readings on concentrations of arsenic, phosphate, and iron – the chemicals we are most concerned about. He also walked us through the water collection process and supplied us with 250 mg bottles for us to use during our trip to Nawalparasi. When we return in a week, we will bring water samples in these bottles for him to test.

Nepal Health Research Center (NHRC): Dr. Krishna Aryal gave us advice on critical challenges we might face in implementing the arsenic removal system, such as costs, education, and trust. He recommended that we come up with innovative ways to market the device and spread awareness of arsenic contamination, such as distributing simple, hand-held fans with educational pictures. He also provided us with several helpful governmental and non-governmental contacts.

 

Nepal Water for Health (NEWAH): Santosh Basnet shared his thoughts on potential strategies to manufacture the device, advising that we center in Nepal rather than India because of lower tariffs and logistical complexity. He also shared a list of organizations for us to contact for help with distribution.

 

In our spare time, Adi, Chad, and I have had a jolly time wandering the streets of Thamel to bargain for yak wool scarves, traditional hats, embellished daggers, singing bowls, and other beautiful and exotic souvenirs. We’ve gorged upon a delicious array of Nepali dishes – Adi and Chad have consumed more chicken momos (dumplings) than there are chickens in Nepal. We also got to see Catching Fire in theaters, which was such a hoot.

Chad and Adi exploring the streets of Tamel.

Adi and Chad left for Nawalparasi today to begin surveying local residents, collecting water samples, and documenting the impact of arsenic. Unfortunately, I got a rather unpleasant case of food poisoning, so I must wait to join them in a few days. Besides that minor hiccup, though, the trip is off to a highly informative and productive start! We’ll update again from Nawalparasi. Until then, peace!

 

 

Huancano Yachaywasi

Huancano Yachaywasi
Huancano Yachaywasi

 

For the past four days, our team has stayed at the lovely Huancano Yachaywasi. This eco-technology demonstration center developed by ProSynergy is three hours southwest of Lima, near Pisco, Peru. It is home to about 50 different agricultural and energy technologies, ranging from a hydraulic ram pump and aquaponic greenhouse to wind and solar energy devices. The Yachaywasi also has livestock and agricultural fields for production. The four well-furnished bungalows lining the outer wall of the Yachaywasi can host four overnight guests each.

Most days groups of 15-20 leaders from surrounding communities visit the Huancano Yachaywasi for a tour and demonstration of the technologies. As ProSynergy’s director Carlos likes to explain, the Yachaywasi is a place for people to dream. Here they are exposed to a variety of different ideas for economical, social, technological, and environmental development. Should they be interested in purchasing and installing one or more of the technologies, the Yachachiq (teacher in Quechua) can assist them in creating a family development plan or business plan and applying for a microfinance loan.
 
Our team assessed the potential for installing a hydropower site for demonstration. Across the street from the Yachaywasi, there is a man-made dirt channel running along the hillside. If DHE were to construct a hydropower site in Huancano, we would divert a portion of the flow from this channel into a settling tank at the top of hill before sending the water through the penstock to the kiosk at the bottom of the hill. However, one area of concern is that there is not a consistent flow rate in the channel. The municipality artificially creates periods of low and high flow in an eight-day cycle as part of an effort to conserve water. In our next blog post, we’ll dive into more specifics of our site surveying techniques.

We have thoroughly enjoyed our time in Huancano. The food and hospitality has been incredible – a big shout out to our new friends Henry and Giovanny! We savored the taste of the fruits and vegetables grown at the Yachaywasi. Our stay would not have been complete without playing a game of pick-up soccer and befriending the guard dogs.

We appreciated Henry’s hospitality and Giovanny’s delicious food.

Greetings from Peru!

Greetings from Peru!

Our team arrived in Lima, Peru on Monday evening, and we have been off to a running start. Thus far we have met with four organizations: Practical Action, Turbinas 3HC, Grupo PUCP, and ProSynergy.

Practical Action (Soluciones Practicas) is a UK-based international NGO which aims to reduce poverty by improving access to technical systems and knowledge. Rafael Escobar, the manager of their energy projects, introduced us to their work in wind, solar, biomass, and hydro renewable energy technologies. Practical Action has implemented 62 micro-hydro sites ranging in size from 0.5 to 200 kW in Peru. Although the majority of their sites are larger than DHE’s scale, it was informative to learn about their approach to training local site operators and financing projects.

Turbinas 3HC is a local company which manufactures cross-flow and Pelton turbines. Engineer Eusebio Castromonte offered a unique perspective on the major players and incentives for promoting micro-hydropower in Peru due to his experience as both an entrepreneur and a former NGO project manager. If DHE installs a hydropower site in Peru, we may consider purchasing a custom turbine from Turbinas 3HC since a locally-fabricated turbine can be most easily maintained and repaired.

Additionally, we met with Grupo de Apoyo Al Sector Royal at Pontficia Universidad Catolica del Peru. Miguel Hadzich leads this research and implementation group which has developed an impressive array of appropriate technologies for the rural Peruvian population. Enrique Mejia gave us a tour of their technology demonstration center, highlighting hydro technologies including a ramp pump and seesaw and pedal-powered pumps. This tour sparked creative ideas as to how DHE might demonstrate the means of producing electricity via hydropower at ProSynergy’s Yachaywasis. We also started to brainstorm ways we might showcase and prototype our technologies closer to home.

Lastly, we met with ProSynergy, the corporate social responsibility arm of SK Innovation. Carlos Guarnizo introduced Pro-Synergy’s two Yachaywasi or eco-technology parks. The Yachaywasis have a social enterprise approach; they introduce local people to a variety of technologies, assist them in constructing a family development plan and business model, and help them to finance such projects via micro-finance. Over 50 appropriate technologies have been installed in each of ProSynergy’s Yachaywasis in Huancano and Pilpichaca. DHE will be spending a week at these two Yachaywasis to assess the potential for installing a hydropower system for demonstration at one of these sites.

We are extremely grateful for the warm Peruvian hospitality we have received our first few days! Now off to Huancano – hasta luego!
