When Cars Ran on Wood: WWII's Ingenious Fuel Solution

These gasifiers converted wood or charcoal into a combustible gas, primarily carbon monoxide and hydrogen, which could power standard internal combustion engines with minor modifications. Though highly effective for basic transport, the system drastically reduced engine power, often by half, and required frequent stops for "refueling" with fresh wood and cleaning of the generator. This widespread adaptation highlights a fascinating chapter of automotive innovation born out of necessity, where sustainability was a wartime imperative.
