    Pure serendipity and probably a good example of why the government should not cut funding for curiosity based research.

    From Slashdotsiliconbits alerts us to the possible use of one of the world's most destructive naturally occurring scourges, the tobacco mosaic virus, to boost the capacity of lithium ion batteries by 10 times. It seems the virus can be made to attach itself to the electrodes in a lithium cell perpendicularly, increasing the surface area of the electrode and greatly improving the battery's capacity to store energy. PhysOrg has some more detail on virus-enhanced batteries. Four years ago we discussed the use of the tobacco mosaic virus to enable fast-switching transistors.


    From FastCompanyThis has all sorts of implications for mobile technology. Imagine every lithium battery in every mobile device you own lasting up to ten times longer. That would mean Apple's new MacBook Airs could hang on in standby mode for 10 months, and Amazon's Kindles may only require charging once every year. Smartphones could have useful call times extending up to a week, and as well as changing how we think about our tech this could have an eco upshot--you'd probably not leave your charger plugged in, sucking down vampire power as much as it does right now.

    Alternatively, batteries could be made with the same capacity that they have now, only ten times smaller--freeing up designers to create all sorts of practically useful gadgets that would be impossible at the moment. Micro-batteries are also possible, meaning rechargeable batteries could replace disposable ones in devices like hearing aids.

    the same thing has been said about bacteria

    More power to the tobacco mosaic virus which wilts tobacco, which in turn, kills stupid humans who smoke. Enemy of our enemy is our friend. icon_lol.gif
