Biomass Energy

From fireplaces to woodstoves to industrial boilers, people have long used biomass as a source of heat. Now, we hear that biomass, in the form of corn or grass, may be the solution to the "oil crisis." In this small, research-based class we will investigate claims about biomass energy and biofuels. What are realistic yields and net energy conversion rates for woody plants, herbaceous perennials or oil crops? How can we convert plant-derived oils, cellulose and starch into usable, practical fuels? What are the environmental and social impacts of using farmland for fuel instead of food, or of converting potentially fragile ecosystems (deserts with irrigation or wetlands) to biomass production? What might be the appropriate mix of crops and technologies for a small community like Hampshire College? Each student will propose and carry out literature and laboratory research on their chosen topic. We will meet twice per week, once for critical examination of the literature and for planning and assessment and once for lab and fieldwork. PRJ, PRS, QUA, REA, WRI
