Cockroaches and rats used as batteries?

An article in today's Manilla Times highlights some local research into using common household pests as energy sources.

A group of scientists from Feati University recently devised a biological fuel cell that uses the enzyme Nicotinamide Adenine Dinucleotide (NAD) to directly convert biochemical energy into electricity. Their research raises the possibility that household pests like mosquitoes, rats, cockroaches and flies could be used as biofuel sources. Cockroaches generated the highest amperage, according to the article.

With increasing oil prices and concerns over fossil fuel-powered climate change, interest in biofuels has perked up in recent years and spurred research into more efficient methods of converting biofuels into electricity utilizing fuel cells. Since biofuels use natural substances, they are often less expensive and cleaner than oil and gas fuels. In developing countries biofuels like wood, charcoal or dried manure are widely used in home cooking and heating.
