Where was the turbo invented?

The invention of the turbocharger is often credited to Alfred Büchi, a Swiss engineer, who patented his design in 1905. However, it's important to note that the concept of using exhaust gases to drive a turbine was explored by others before him.

Here's a brief timeline:

* 1872: Franz Stolze, a German engineer, filed a patent for a device using exhaust gases to drive a fan, although his design was not practical.

* 1905: Alfred Büchi patented his design for a turbocharger, which was initially intended for use in stationary engines.

* 1920s-1930s: Büchi's design was further developed and applied to aircraft engines, particularly during World War II.

* 1950s-1960s: Turbochargers began to be used in automobiles, initially in diesel engines.

* 1970s-present: Turbochargers have become increasingly popular in gasoline engines due to their fuel efficiency and performance benefits.

Therefore, while Büchi is widely recognized as the inventor of the turbocharger, it's important to acknowledge the contributions of others who explored the concept before him.
