THIS, my friends, is the future of science

When I first got this job sorting, categorizing and segregating chemicals, I thought "where do all these things come from?" Turns out, many of the strange chemicals that are used out there are byproducts of other reactions for things you would never think of. Everything we use, eat and apply is made through some kind of chemical process and those processes always have waste of some form. As society progresses and continues to have more and different needs, we have more and different manufacturing processes producing more and different types of waste. Tires, cosmetics, cleaning products, petroleum refining, everything has a unique waste product that can sometimes be put to work somewhere else. Even chocolate!!

OK so, wow, they're powering a fan but think about it this way: Let's say Hershey's has a factory, a big one, that makes all kinds of yummy, delicious confections. A mysterious salesperson comes knocking on the door and says "hey, my company has found a way to take the stuff you pay to get rid of and turn it into something you can sell." Several million dollars later, Hershey's has a low-cost hydrogen fuel pump for they're employees, a massive fuel cell stack to offset their electricity costs and a pipeline to sell hydrogen back to the energy grid. Utopian? I think not!
