Which Virus Is Improving Batteries?

Senior Contributor

The Tobacco mosaic virus is probably something you’ve never heard of, but it’s going to make your gadgets run a lot longer.

The key with any battery is to get as much surface area on the electrode as possible to gather as many electrons as possible. How’s a virus helping with that?

Well, by modifying the gene slightly, putting a film on the electrode and letting the virus do what comes naturally. It builds nanorod structures on the electrode, expanding the surface area to ridiculous lengths. How ridiculous?

Try ten times as efficient. Yep, your laptop is about to become that much more awesome, and my netbook is officially usable beyond an hour once these things come out. We love the future!
