We’ve seen Doom running on printers, smart watches, digital cameras, and even on an ATM. Impressive as these feats are, the unlikely hardware running Doom in all these cases are getting their electricity from traditional sources.Anyone who’s been through grade school science class can probably tell you that potatoes can be used to generate electricity. Stick some zinc and copper into a potato, and the potato’s acids and salts essentially act as a chemical battery. Line up enough potatoes and you can use them to power something, though even with several potatoes you’ll only have enough power for something very small.But how many potatoes would it take to generate enough electricity to run Doom? YouTuber Equalo, over the course of several long days and nights in his potato-filled garage, decided to find out.Equalo set out to get Doom running on a Raspberry Pi Zero, calculating he’d need about 770 slices of potatoes to generate the 100-120 milliamps and 5 volts required. He brought home 100 pounds of potatoes, boiled them (which increases the amperage), sliced them, and wired them up. Then he plugged in the Raspberry Pi.And… it didn’t work. Despite pulling roughly enough amperage from those sliced potatoes, the tiny computer just wouldn’t boot. But Equalo wasn’t ready to give up.
