Engineer builds self-powered driving potato
A single potato doesn’t generate a lot of electricity, but if you collect that slow trickle into a capacitor—a sort of battery—you get enough of a charge to power a pair of electric motors. After sitting motionless for a quarter of an hour, Marek’s upgraded potato, which he named Pontus, was able to drive in a quick short burst for just over three inches, or a top speed of around 24 feet per day.
Marek eventually added the ability for Pontus to randomly choose a direction it could drive in when charged up, and aside from just spinning in circles, at times it would find sunlight to park in, or seemingly follow him around the room.
