Scientists Use Viruses to Make Batteries
Posted 08/25/08 at 11:39:21 AM | by Paul Lilly
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?

Because they are so tiny

Because they are so tiny they will only carry a minimal amount of capacity. This would be used to power microscopic battery powered devices. So it would require so many of these that they would share the same mass and size of a typical car battery to satisfy the power needs of a car.
If they're cheap...

If these nano-batteries are so cheap then why isn't there an application for them! Do you know how much smaller and lighter my laptop could be if it didn't have to rely on this giant clunky Li Ion battery? There should literally be thousands of applications for these things. Cell phones, MP3 players. Portable anything.
Why not build/link enough of them so that they are macroscopic in scale and power a car? To say there is no application for these things is absolutley ridiculous.
This is nothing new. I mean

This is nothing new. I mean as far as viruses go. Scientists have been using viruses for all kinds of things like killing cancer and stuff.. Manufacturing nano robots..
