An atom is the smallest unit of an element that maintains the properties of that element. And element is a pure substance made of only one kind of atom. A compound is the substance that is made from the atoms of two or more elements that are chemically bonded. Water is an example of a compound because it is one of many compounds that

Total mass input includes feedstock‚ air and total water and total mass outputs were comprised of producer gas and charcoal. The average mass balance was found to be 89% of six experimental runs. In the study they found the importance of moisture content. When they increased moisture content‚ the biomass consumption rate was decreased and vice versa. The energy required

Saltpeter comes from mining. It was thought to be the secret to immortality in ancient china‚ so Chinese alchemists performed many experiments using saltpeter. Charcoal came from burnt willow tree. The mixture for gunpowder has a composition of 75% saltpeter‚ 15% charcoal‚ and 10%sulfur (Szczepanski). Gunpowder had

A case in point is Otto Mears a German immigrant that built most of the three foot gauge railroads in the Colorado Rockies. He had a third grade education
