Australian Scientists: Beer is the Ultimate Energy Drink
This blog has chronicled the miracle health benefits of beer. Now it appears beer can also supply energy -- electrical energy. Researchers at the University of Queensland and Foster's Group believe they have found a way to create energy from brewery wastewater and bacteria.
Scientists have received a grant to install the experimental microbial fuel cell at a Foster's brewery outside of Brisbane. The fuel cell battery uses bacteria to consume water-soluble brewing waste such as sugar, starch and alcohol. The result is electricity and clean water.
A prototype of the battery has been operational in a university laboratory since earlier this year. The brewery fuel cell is expected to produce 2 kilowatts of power or about what the average household consumes in electricity. The scientists, however, are excited because the real benefit of the technology is wastewater treatment. The electrical generation is a bonus that could be replicated at other breweries, wineries and distilleries.
