Grooving in the right direction using motors driven backward

The backdriven stepper motors produce notes over four octaves

After using an oscilloscope to confirm that stepper motors driven backward produced an alternating current, University of Maryland senior Josh Sheldon decided to turn the resulting waveforms into audible sounds. He attached a series of steppers to a frame, had them backdriven by a large spinning cone and then lowered the motors one at a time using a piano keyboard to produce a tune or two. The result is the magical Stepper Organ, and the output is just a little bit eerie.

Fungi put to work extracting lithium from discarded batteries

Researchers have used three strains of fungi to extract valuable metals from discarded batteries

At the heart of devices like smartphones, tablets and electric cars are rechargeable batteries, and at the heart of those is lithium. With demand growing, mining isn't sustainable long-term, so researchers are exploring the difficult task of reclaiming lithium from old discarded batteries. A new study has put three strains of fungi to work to extract these valuable materials from electronic waste, which could lead to a safer and greener battery recycling system.

Oddball electric scooter makes it to production

The BOXX scooter will hit 54 mph in top spec

Here at New Atlas, we come across a lot of out of the box ideas aiming to revolutionize the way we move. The BOXX scooter from 2012 fits the bill in more ways than one. Back then the team behind the wacky e-bike design was chasing preorders in the hope of making it to mass production. In 2016, it's moved from a pie-in-the-sky idea to a production reality with 97 km (60 mi) of all-electric range.
