A computer powered by fire. I can't quite love this enough.

That Stirling engine has a steady, unhurried rhythm - almost like it belongs in a Mediterranean seaside cafe, not just running DOOM.

On one level I ask “why?”, yet I caught myself thinking “I wonder where I can get one?”😂

There are two different engines here: the Stirling engine producing electricity, and the game engine using it. The creator links doom-nano, whose author describes a simplified raycaster with Doom sprites, closer to Wolfenstein 3D than the original Doom. That detail makes the engineering more interesting: the tiny generator is paired with a deliberately tiny workload

A computer that needs fire instead of a power outlet Enthusiast built a real steampunk computer that generates electricity from a flame. No batteries or power supply — the fire heats a miniature Stirling engine, which drives a generator to produce electricity. The principle is simple: heated gas inside the engine expands and pushes a piston, then cools and contracts. The cycle repeats, spinning a flywheel that turns the generator. The system produces only about 150 mW, so the computer is extremely energy-efficient. It uses an ESP32-C3, a monochrome 128×64 OLED display and a 16-key keyboard. Wi-Fi and Bluetooth are disabled, and the processor clock speed has been reduced. Yet even that tiny amount of power is enough to run CHIP-8, including games such as Tetris, Snake and Pong. The creator also built in a simple editor that lets users write their own programs directly on the “fire-powered” computer. And the Stirling engine itself is more than two centuries old — Robert Stirling patented it back in 1816. Video: YouTube/PickentCode
