I found this video yesterday and thought at first the video was about peanut brittle. I was hungry. As you could tell by my last post, food was on my mind – and it was a good tie-in for the stuff I found. I put the other video up first because it was crisper. In any case, this is quite an inventive little contraption, and not expensive like the algae harvesting and oil processing.
Here Nick Flavo, a college student at Rowan University, shows you how to make briquettes out of peanut shells, which you normally throw away. The briquettes are good for cooking fires in developing countries like Gambia, which has many peanut farms but relatively expensive energy sources. The method could also perhaps be used by airline company suppliers who want to find a new way to make money with their waste. They’ll need a bigger briquette piston though.
In fact, Flavo says that you can basically briquette any waste product. It would be interesting to experiment.
Gambia is a small country that follows the Gambia River in West Africa. It covers an area of about 11,300 square kilometers. Although it has enjoyed relative political stability in recent history, about a third of its people live in severe poverty on about $1.25 a day. It has one of the lowest Human Development Index scores, which is compiled by the UNDP. Peanut products are its number one export by far, which makes it susceptible to their particular price shocks. 75 percent of the population is employed by the livestock or the agricultural sector.
