Scientists Use Viruses to Make Batteries


Engineers have come up with a bit of sick technology, and we're not using that term as slang. Instead, they've found a way to assemble a key component of a microscopic battery using viruses, potentially paving the way for cheap and simple construction of pint-sized power sources.

The MIT group had previously been able to genetically engineer viruses to make a protein skin capable of attracting bits of metal, and this new research builds on that by having those same viruses build a specific part. In the MIT experiment, the genetically engineered viruses would help build the anode portion of a battery by attracting cobalt oxide. And more than just a proof of concept, the process has been drawing attention because of its ease-of-use and low cost.

One stumbling block preventing the widespread use of viruses in battery construction is a lack of application. There currently aren't any devices that would require a battery roughly one tenth the width of a human hair, though future applications could see the technology being used in nanotechnology.

Anyone else see the plot for a bad B-movie shaping up?
