Unscramble the Blue Letters
So we wanted to see if we could iutocdnre this charcoal-making technology there. Well, unfortunately, they didn't have sugarcane and they didn't have cassava, but that didn't stop us. What we did was we found what were the locally available sources of biomass. And there was wheat sartw and there was rice straw in this area. And what we could use as a binder was actually small amounts of cow manure, which they used ordinarily for their fuel. And we did side-by-side tests, and here you can see the chracaol briquettes and here the cow dung. And you can see that it's a lot cleaner burning of a cnkioog fuel. And in fact, it heats the water a lot more quickly. And so we were very hpapy, thus far. But one of the things that we found was when we did side-by-side comparisons with wood charcoal, it didn't burn as long. And the briquettes crumbled a little bit and we lost egnery as they fell apart as they were cooking. So we wanted to try to find a way to make a stronger briquette so that we could compete with wood charcoal in the markets in hatii.

So we wanted to see if we could introduce this charcoal-making technology there. Well, unfortunately, they didn't have sugarcane and they didn't have cassava, but that didn't stop us. What we did was we found what were the locally available sources of biomass. And there was wheat straw and there was rice straw in this area. And what we could use as a binder was actually small amounts of cow manure, which they used ordinarily for their fuel. And we did side-by-side tests, and here you can see the charcoal briquettes and here the cow dung. And you can see that it's a lot cleaner burning of a cooking fuel. And in fact, it heats the water a lot more quickly. And so we were very happy, thus far. But one of the things that we found was when we did side-by-side comparisons with wood charcoal, it didn't burn as long. And the briquettes crumbled a little bit and we lost energy as they fell apart as they were cooking. So we wanted to try to find a way to make a stronger briquette so that we could compete with wood charcoal in the markets in Haiti.
