Viruses could power devicesMore. Faster. Hat tip BoingBoing Posted by DaveH at April 7, 2009 3:59 PM | TrackBack
A computer virus won’t help your laptop work — but a biological virus could. Tweaking their genes just so could engineer viruses for making the rechargeable lithium ion batteries that power devices such as laptops, iPods and cell phones, researchers report online April 2 in Science.
In previous research, the same team used viruses to construct the negative electrode, or anode, of the battery. In the new work, the researchers engineered viruses for the positive electrode, or cathode. When the two are put together, the virus batteries should perform better than traditional lithium ion batteries and also be environmentally friendly, the team reports.
“Because the viruses are living organisms, we had to use only water-based solvents, no high pressures and no high temperatures,” says Angela Belcher, a materials scientist at the Massachusetts Institute of Technology in Cambridge and a study coauthor.
