Bacteria Battery from MAKE Volume 30

How-To: Bacteria Battery

Did you know you can generate electricity from the “metal-breathing” anaerobic bacteria found in ordinary mud? Having no oxygen to breathe, these bacteria produce energy for their growth by transferring electrons to clumps of rust and other metal oxides, in a process called dissimilatory metal reduction. Dr. Ashley Franks, director of K–12 outreach at the […]

Asteroid-Grabbing Microspines

NASA JPL researchers present a 250-mm diameter omni-directional anchor that uses an array of claws with suspension flexures, called microspines, designed to grip rocks on the surfaces of asteroids and comets and to grip the cliff faces and lava tubes of Mars. [via Techland; thanks Bigpaws!]

Engineer Guy vs. The Smartphone Accelerometer

Engineer Guy vs. The Smartphone Accelerometer

Here, with great fanfare, is the second installment of Engineer Guy Series #4: theMEMSaccelerometer. With typical flair, Bill and his production team take us from the basic concept of an accelerometer (using the familiar ball-on-a-spring model), through the analogous silicon device that lets your smartphone tell up from down, all the way to the anisotropic etching techniques used to It’s wonders all the way down, with Bill, as usual.
