(Original title: The world's first self-driving potato is a bit slower
A self-driving car should be familiar to us, but what happened to a "self-driving potato" in Poland recently? From the "Daily Mail", Marek Baczynski, an engineer from Poland, brought ordinary potatoes to the laboratory and developed the world's first potato self-driving toy car Pontus. Marek collects energy from the potatoes through an energy harvesting chip and stores it in a capacitor. Once the capacitor has accumulated enough power, it will drive Pontus to walk.
According to Marek Baczynski, each advancement of a single potato plant must be prepared for 15 minutes of advancement beforehand, and it is only possible to walk 8 centimeters. The efficiency in the day is 7.5 meters. But on the second day, the device will take 30 minutes to accumulate enough energy to start, and a week later, the start of energy storage has already reached 8 hours. Marek calculated that it was possible to generate approximately 0.48 milliwatts of electricity per potato using a pair of electrodes.
The Pontus is equipped with a miniature control panel and a motor removed from the CD that allows the car to randomly select driving directions, such as forward and backward, each time it advances. The overall cost of this toy car is about 10 US dollars, 70 yuan contract.
It is worth mentioning that Marek Baczynski's inventive brain hole is very large. Before that, he used the APP on the iPhone to control the status of ballpoint pens in real time, and replaced the light bulbs with drones.
