Dialogue: 0,0:01:17.00,0:01:19.00,Default,,0000,0000,0000,,A couple years ago there was severe flooding Dialogue: 0,0:01:19.00,0:01:20.00,Default,,0000,0000,0000,,that led to thousands of deaths -- Dialogue: 0,0:01:20.00,0:01:22.00,Default,,0000,0000,0000,,that's directly attributable to the fact Dialogue: 0,0:01:22.00,0:01:25.00,Default,,0000,0000,0000,,that there are no trees on the hills to stabilize the soil. Dialogue: 0,0:01:25.00,0:01:29.00,Default,,0000,0000,0000,,So the rains come, they go down the rivers, and the flooding happens. Dialogue: 0,0:01:30.00,0:01:33.00,Default,,0000,0000,0000,,Now one of the reasons why there are so few trees is this: Dialogue: 0,0:01:33.00,0:01:36.00,Default,,0000,0000,0000,,people need to cook, and they harvest wood Dialogue: 0,0:01:36.00,0:01:39.00,Default,,0000,0000,0000,,and they make charcoal in order to do it.

Dialogue: 0,0:02:02.00,0:02:05.00,Default,,0000,0000,0000,,So not surprisingly, there's a lot of effort Dialogue: 0,0:02:05.00,0:02:09.00,Default,,0000,0000,0000,,that's been done to look at alternative cooking fuels. Dialogue: 0,0:02:09.00,0:02:12.00,Default,,0000,0000,0000,,About four years ago I took a team of students down to Haiti, Dialogue: 0,0:02:12.00,0:02:15.00,Default,,0000,0000,0000,,and we worked with Peace Corps volunteers there. Dialogue: 0,0:02:15.00,0:02:17.00,Default,,0000,0000,0000,,This is one such volunteer, Dialogue: 0,0:02:17.00,0:02:20.00,Default,,0000,0000,0000,,and this is a device that he had built in the village where he worked. Dialogue: 0,0:02:20.00,0:02:22.00,Default,,0000,0000,0000,,And the idea was that you could take waste paper; Dialogue: 0,0:02:22.00,0:02:26.00,Default,,0000,0000,0000,,you could compress it; and make briquettes that could be used for fuel. Dialogue: 0,0:02:26.00,0:02:28.00,Default,,0000,0000,0000,,But this device was very slow. Dialogue: 0,0:02:28.00,0:02:31.00,Default,,0000,0000,0000,,So our engineering students went to work on it, Dialogue: 0,0:02:31.00,0:02:34.00,Default,,0000,0000,0000,,and with some very simple changes, Dialogue: 0,0:02:34.00,0:02:37.00,Default,,0000,0000,0000,,they were able to triple the throughput of this device. Dialogue: 0,0:02:37.00,0:02:39.00,Default,,0000,0000,0000,,So you could imagine they were very excited about it. Dialogue: 0,0:02:39.00,0:02:43.00,Default,,0000,0000,0000,,And they took the briquettes back to MIT so that they could test them. Dialogue: 0,0:02:43.00,0:02:48.00,Default,,0000,0000,0000,,And one of the things that they found was they didn't burn. Dialogue: 0,0:02:48.00,0:02:51.00,Default,,0000,0000,0000,,So it was a little discouraging to the students. Dialogue: 0,0:02:52.00,0:02:56.00,Default,,0000,0000,0000,,And in fact if you look closely, right here, Dialogue: 0,0:02:56.00,0:02:58.00,Default,,0000,0000,0000,,you can see it says, "U.S. Peace Corps." Dialogue: 0,0:02:58.00,0:03:02.00,Default,,0000,0000,0000,,As it turns out, there actually wasn't any waste paper in this village. Dialogue: 0,0:03:02.00,0:03:06.00,Default,,0000,0000,0000,,And while it was a good use of government paperwork Dialogue: 0,0:03:06.00,0:03:08.00,Default,,0000,0000,0000,,for this volunteer to bring it back with him to his village (Laughter), Dialogue: 0,0:03:08.00,0:03:10.00,Default,,0000,0000,0000,,it was 800 kilometers away. Dialogue: 0,0:03:10.00,0:03:14.00,Default,,0000,0000,0000,,And so we thought perhaps there might be a better way Dialogue: 0,0:03:14.00,0:03:16.00,Default,,0000,0000,0000,,to come up with an alternative cooking fuel. Dialogue: 0,0:03:16.00,0:03:19.00,Default,,0000,0000,0000,,What we wanted to do is we wanted to make a fuel Dialogue: 0,0:03:19.00,0:03:22.00,Default,,0000,0000,0000,,that used something that was readily available on the local level. Dialogue: 0,0:03:22.00,0:03:26.00,Default,,0000,0000,0000,,You see these all over Haiti as well. They're small-scale sugar mills. Dialogue: 0,0:03:26.00,0:03:27.00,Default,,0000,0000,0000,,And the waste product from them Dialogue: 0,0:03:27.00,0:03:31.00,Default,,0000,0000,0000,,after you extract the juice from the sugarcane is called "bagasse." Dialogue: 0,0:03:31.00,0:03:34.00,Default,,0000,0000,0000,,It has no other use. It has no nutritional value, Dialogue: 0,0:03:34.00,0:03:36.00,Default,,0000,0000,0000,,so they don't feed it to the animals. Dialogue: 0,0:03:36.00,0:03:40.00,Default,,0000,0000,0000,,It just sits in a pile near the sugar mill until eventually they burn it. Dialogue: 0,0:03:40.00,0:03:43.00,Default,,0000,0000,0000,,What we wanted to do was we wanted to find a way Dialogue: 0,0:03:43.00,0:03:46.00,Default,,0000,0000,0000,,to harness this waste resource and turn it into a fuel Dialogue: 0,0:03:46.00,0:03:49.00,Default,,0000,0000,0000,,that would be something that people could easily cook with, Dialogue: 0,0:03:49.00,0:03:51.00,Default,,0000,0000,0000,,something like charcoal. Dialogue: 0,0:03:51.00,0:03:56.00,Default,,0000,0000,0000,,So over the next couple of years, students and I worked to develop a process. Dialogue: 0,0:03:56.00,0:04:00.00,Default,,0000,0000,0000,,So you start with the bagasse, and then you take a very simple kiln Dialogue: 0,0:04:00.00,0:04:03.00,Default,,0000,0000,0000,,that you can make out of a waste fifty five-gallon oil drum. Dialogue: 0,0:04:03.00,0:04:07.00,Default,,0000,0000,0000,,After some time, after setting it on fire, you seal it Dialogue: 0,0:04:07.00,0:04:10.00,Default,,0000,0000,0000,,to restrict the oxygen that goes into the kiln, Dialogue: 0,0:04:10.00,0:04:14.00,Default,,0000,0000,0000,,and then you end up with this carbonized material here. Dialogue: 0,0:04:14.00,0:04:16.00,Default,,0000,0000,0000,,However, you can't burn this. It's too fine Dialogue: 0,0:04:16.00,0:04:20.00,Default,,0000,0000,0000,,and it burns too quickly to be useful for cooking. Dialogue: 0,0:04:20.00,0:04:24.00,Default,,0000,0000,0000,,So we had to try to find a way to form it into useful briquettes. Dialogue: 0,0:04:24.00,0:04:27.00,Default,,0000,0000,0000,,And conveniently, one of my students was from Ghana, Dialogue: 0,0:04:27.00,0:04:32.00,Default,,0000,0000,0000,,and he remembered a dish his mom used to make for him called "kokonte," Dialogue: 0,0:04:32.00,0:04:35.00,Default,,0000,0000,0000,,which is a very sticky porridge made out of the cassava root. Dialogue: 0,0:04:35.00,0:04:37.00,Default,,0000,0000,0000,,And so what we did was we looked, and we found Dialogue: 0,0:04:37.00,0:04:41.00,Default,,0000,0000,0000,,that cassava is indeed grown in Haiti, under the name of "manioc." Dialogue: 0,0:04:41.00,0:04:43.00,Default,,0000,0000,0000,,And in fact, it's grown all over the world -- Dialogue: 0,0:04:43.00,0:04:47.00,Default,,0000,0000,0000,,yucca, tapioca, manioc, cassava, it's all the same thing -- Dialogue: 0,0:04:47.00,0:04:49.00,Default,,0000,0000,0000,,a very starchy root vegetable. Dialogue: 0,0:04:49.00,0:04:52.00,Default,,0000,0000,0000,,And you can make a very thick, sticky porridge out of it, Dialogue: 0,0:04:52.00,0:04:56.00,Default,,0000,0000,0000,,which you can use to bind together the charcoal briquettes. Dialogue: 0,0:04:56.00,0:04:59.00,Default,,0000,0000,0000,,So we did this. We went down to Haiti. Dialogue: 0,0:04:59.00,0:05:02.00,Default,,0000,0000,0000,,These are the graduates of the first Ecole de Chabon, Dialogue: 0,0:05:02.00,0:05:04.00,Default,,0000,0000,0000,,or Charcoal Institute. And these -- Dialogue: 0,0:05:04.00,0:05:06.00,Default,,0000,0000,0000,,(Laughter) Dialogue: 0,0:05:06.00,0:05:11.00,Default,,0000,0000,0000,,-- that's right. So I'm actually an instructor at MIT as well as CIT. Dialogue: 0,0:05:11.00,0:05:15.00,Default,,0000,0000,0000,,And these are the briquettes that we made. Dialogue: 0,0:05:15.00,0:05:20.00,Default,,0000,0000,0000,,Now I'm going to take you to a different continent. This is India, Dialogue: 0,0:05:20.00,0:05:25.00,Default,,0000,0000,0000,,and this is the most commonly used cooking fuel in India; it's cow dung. Dialogue: 0,0:05:25.00,0:05:29.00,Default,,0000,0000,0000,,And more than in Haiti, this produces really smoky fires, Dialogue: 0,0:05:29.00,0:05:32.00,Default,,0000,0000,0000,,and this is where you see the health impacts Dialogue: 0,0:05:32.00,0:05:36.00,Default,,0000,0000,0000,,of cooking with cow dung and biomass as a fuel. Dialogue: 0,0:05:36.00,0:05:39.00,Default,,0000,0000,0000,,Kids and women are especially affected by it, Dialogue: 0,0:05:39.00,0:05:41.00,Default,,0000,0000,0000,,because they're the ones who are around the cooking fires. Dialogue: 0,0:05:41.00,0:05:44.00,Default,,0000,0000,0000,,So we wanted to see if we could introduce Dialogue: 0,0:05:44.00,0:05:46.00,Default,,0000,0000,0000,,this charcoal-making technology there. Dialogue: 0,0:05:46.00,0:05:49.00,Default,,0000,0000,0000,,Well unfortunately, they didn't have sugarcane Dialogue: 0,0:05:49.00,0:05:52.00,Default,,0000,0000,0000,,and they didn't have cassava, but that didn't stop us. Dialogue: 0,0:05:52.00,0:05:56.00,Default,,0000,0000,0000,,What we did was we found what were the locally available sources of biomass. Dialogue: 0,0:05:56.00,0:05:59.00,Default,,0000,0000,0000,,And there was wheat straw and there was rice straw in this area. Dialogue: 0,0:05:59.00,0:06:01.00,Default,,0000,0000,0000,,And what we could use as a binder Dialogue: 0,0:06:01.00,0:06:03.00,Default,,0000,0000,0000,,was actually small amounts of cow manure, Dialogue: 0,0:06:03.00,0:06:06.00,Default,,0000,0000,0000,,which they used ordinarily for their fuel. Dialogue: 0,0:06:06.00,0:06:10.00,Default,,0000,0000,0000,,And we did side-by-side tests, and here you can see Dialogue: 0,0:06:10.00,0:06:13.00,Default,,0000,0000,0000,,the charcoal briquettes and here the cow dung. Dialogue: 0,0:06:13.00,0:06:16.00,Default,,0000,0000,0000,,And you can see that it's a lot cleaner burning of a cooking fuel. Dialogue: 0,0:06:16.00,0:06:19.00,Default,,0000,0000,0000,,And in fact, it heats the water a lot more quickly. Dialogue: 0,0:06:19.00,0:06:21.00,Default,,0000,0000,0000,,And so we were very happy, thus far. Dialogue: 0,0:06:21.00,0:06:23.00,Default,,0000,0000,0000,,But one of the things that we found Dialogue: 0,0:06:23.00,0:06:26.00,Default,,0000,0000,0000,,was when we did side-by-side comparisons with wood charcoal, Dialogue: 0,0:06:26.00,0:06:29.00,Default,,0000,0000,0000,,it didn't burn as long. And the briquettes crumbled a little bit, Dialogue: 0,0:06:29.00,0:06:32.00,Default,,0000,0000,0000,,and we lost energy as they fell apart as they were cooking. Dialogue: 0,0:06:32.00,0:06:36.00,Default,,0000,0000,0000,,So we wanted to try to find a way to make a stronger briquette Dialogue: 0,0:06:36.00,0:06:40.00,Default,,0000,0000,0000,,so that we could compete with wood charcoal in the markets in Haiti. Dialogue: 0,0:06:40.00,0:06:44.00,Default,,0000,0000,0000,,So we went back to MIT, we took out the Instron machine, Dialogue: 0,0:06:44.00,0:06:47.00,Default,,0000,0000,0000,,and we figured out what sort of forces did you need Dialogue: 0,0:06:47.00,0:06:49.00,Default,,0000,0000,0000,,in order to compress a briquette to the level Dialogue: 0,0:06:49.00,0:06:52.00,Default,,0000,0000,0000,,that you actually are getting improved performance out of it? Dialogue: 0,0:06:52.00,0:06:56.00,Default,,0000,0000,0000,,And at the same time that we had students in the lab looking at this, Dialogue: 0,0:06:56.00,0:07:02.00,Default,,0000,0000,0000,,we also had community partners in Haiti working to develop the process, Dialogue: 0,0:07:02.00,0:07:08.00,Default,,0000,0000,0000,,to improve it and to make it more accessible to people in the villages there. Dialogue: 0,0:07:08.00,0:07:10.00,Default,,0000,0000,0000,,And after some time, Dialogue: 0,0:07:10.00,0:07:15.00,Default,,0000,0000,0000,,we developed a low-cost press that allows you to produce charcoal, Dialogue: 0,0:07:15.00,0:07:22.00,Default,,0000,0000,0000,,which actually now burns longer, cleaner than wood charcoal. Dialogue: 0,0:07:22.00,0:07:26.00,Default,,0000,0000,0000,,So now we're in a situation where we have a product, which is actually better Dialogue: 0,0:07:26.00,0:07:29.00,Default,,0000,0000,0000,,than what you can buy in Haiti in the marketplace, Dialogue: 0,0:07:29.00,0:07:32.00,Default,,0000,0000,0000,,which is a very wonderful place to be. Dialogue: 0,0:07:33.00,0:07:39.00,Default,,0000,0000,0000,,In Haiti alone, about 30 million trees are cut down every year.
