When
a South Dakota Mines research team announced in March that it had successfully
generated power with tomato waste, the world and international media elite immediately
took notice. After all, it’s not every day that you hear about fruit being
converted into electricity.
The
research group led by Dr. Venkata Gadhamshetty, Mines graduate students and a
researcher each from Princeton University and Florida Gulf Coast University
announced findings at the 251st National Meeting & Exposition of the
American Chemical Society (ACS) in San Diego
Within
hours, Dr. Gadhamshetty was interviewing with the BBC, and the news was written
about by CNN, Newsweek, MSN, Yahoo news and the Times of India (to name a few),
highlighting just one example of the important, world-changing research being
conducted at the South Dakota School of Mines & Technology in Rapid City.
The pilot project involves a
biological-based fuel cell that uses tomato waste from harvests, grocery store
shelves and production plants such as ketchup factories. The inherent
characteristics of the decomposing leftovers make it a perfect fuel source for
enhancing electrochemical reactions, Dr. Gadhamshetty says.
Researchers designed and built a
new electrochemical device to test and extract electrons from the defective
tomatoes. The power output from their mini reactor is small: 10 milligrams of
tomato waste resulted in 0.3 watts of electr...
