Cheap, High-Performance Green Battery Runs On Rotten Apples (gizmag.com)

Posted by yaelk on from the a-bad-apple dept.

Zothecula writes: Researchers at the Karlsruhe Institute of Technology (KIT) have repurposed discarded apples to build cheap and high-performance sodium-ion batteries, making a green technology even greener. The advance could find use in grid storage and, after further development, compete with lithium-ion cells to power portable electronics and low-end electric cars.

    How would this compare to using discarded oranges.

      I'm not sure in which state Karlsruhe is, but once again: Kudos to our world-class American Engineering!

      I guess the parent AC learned geography from a world-class American School.

    Android has had this feature from day one. Glad to see Apple is finally catching up.

      I guess they're going to be using Apple /// computers. Those were pretty rotten.

    Wake me when you can run a toaster with it.

    It seems that every week we some "green power" technology that produces 0.3 yoctowatts of power, involves the slight jostling of 3 electrons, and claims industrial level of application.

    I call bullshit. Stop stealing ideas from the local school science fair and develop something that will power something useful, and demonstrate it.

    I don't think farmers are going to be growing rotten apples.

    I'd think running on sour grapes would drastically increase supplies and yield more potent batteries.
