Bizarre self-driving potato that doesn't need a battery

An engineer in Poland has taken the age-old potato clock experiment to the next level. Marek Baczynski has revealed what he says is the world's first self-driving potato, and it runs on its own electricity. On YouTube, the inventor explains how an energy harvester and a capacitor can be used to store the'minuscule' energy generated by the potato, eventually powering it enough to drive – and, with a simple script, he granted it'the gift of freedom.' The potato takes about 15 minutes to charge, which will carry it just a few inches at a time. According to Baczynski, it can travel about seven and a half meters (24.6 feet) over the course of an entire day Potatoes are able to conduct electricity thanks to the presence of electrolytes.
