So you start with the bagasse, and then you take a very simple kiln that you can make out of a waste fifty five-gallon oil drum. After some time, after setting it on fire, you seal it to rircestt the oeyxgn that goes into the kiln, and then you end up with this coebazrnid material here. However, you can't burn this. It's too fine and it burns too quickly to be useful for cooking. So we had to try to find a way to form it into useful briquettes. And conveniently, one of my stduents was from ghnaa, and he rembeeermd a dish his mom used to make for him called "kokonte," which is a very sticky prrgiode made out of the cassava root. And so what we did was we looked, and we found that cassava is indeed grown in Haiti, under the name of "manioc." In fact, it's grown all over the world — yucca, tapioca, manioc, cassava, it's all the same thing — a very starchy root vegetable. And you can make a very thick, sticky porridge out of it, which you can use to bind together the caahcorl briquettes. So we did this. We went down to htaii.

Original Text
So you start with the bagasse, and then you take a very simple kiln that you can make out of a waste fifty five-gallon oil drum. After some time, after setting it on fire, you seal it to restrict the oxygen that goes into the kiln, and then you end up with this carbonized material here. However, you can't burn this. It's too fine and it burns too quickly to be useful for cooking. So we had to try to find a way to form it into useful briquettes. And conveniently, one of my students was from Ghana, and he remembered a dish his mom used to make for him called "kokonte," which is a very sticky porridge made out of the cassava root. And so what we did was we looked, and we found that cassava is indeed grown in Haiti, under the name of "manioc." In fact, it's grown all over the world — yucca, tapioca, manioc, cassava, it's all the same thing — a very starchy root vegetable. And you can make a very thick, sticky porridge out of it, which you can use to bind together the charcoal briquettes. So we did this. We went down to Haiti. These are the graduates of the first Ecole de Charbon, or Charcoal Institute. And these —
