Charles Nelson Pogue (15 September 1897 – 1985) was a Canadian mechanic and inventor who in the 1930s filed a series of US patents for a miracle carburetor (sometimes called the Winnipeg carburetor[1]) that would allegedly enable a car to attain 200 miles per US gallon (1.2 L/100 km; 240 mpg‑imp); it was described as a vaporising carburetor or sometimes a catalytic carburetor. But the 1936 (possibly 1932) announcement was not followed by any verifiable tests or demonstrations.[2]
