electricity

Proposals ranging from sharing electricity savings with lab users to allowing students to bid on how much electricity they can save are among the ideas that students suggested in the Olin Sustainability Case Competition. The winner gets $5,000 cash and a meeting to present her proposal to the chancellor and other top administrators.

Instead, these are the components of a new high-school science curriculum being developed by researchers at Washington University and two St. Louis area high-school teachers.

Hopes are that the fuel cell can be scaled up even more and function as a viable energy form.In the midst of the worldwide energy crisis, researchers at Washington University in St. Louis have been continuing their work on a microbial fuel cell that generates electricity from wastewater. Advances in the design of this fuel cell in the last year have increased the power output by a factor of 10 and future designs, already in the minds of the researchers, hope to multiply that power output by 10 times again. If that goal can be achieved, the fuel cell could be scaled up for use in food and agricultural industries to generate electrical power – all with the wastewater that today goes right down the drain.

Lars Angenent, Ph.D., assistant professor of Chemical Engineering, and a member of the University’s Environmental Engineering Science Program, has devised a microbial fuel cell which he calls an upflow microbial fuel cell (UMFC) that is fed continually and, unlike most microbial fuel cells, works with chambers atop each other rather than beside each other.

Photograph, 1904.April 30, 2004, marks the 100th anniversary of the 1904 World’s Fair, an event that showcased science advancements that startled the imagination a century ago and foretold technology still in place today. The fair was headquartered on the campus of Washington University in St. Louis, where significant scientific developments continue today, most notably at the nation’s second-ranked medical school but also across many science and engineering disciplines.
