How is a turbosupercharger (or turbocharger) driven?

Explanation:
A turbocharger is driven by the energy in the exhaust gas. Exhaust flows through a turbine inside the turbo, making the turbine spin. That turbine is connected to a shaft that also spins the compressor impeller. As the compressor spins, it draws in and compresses more air, pushing it into the engine so more fuel can be burned and power increases. This setup uses waste exhaust energy, not electricity from a generator, not a belt from the crankshaft, and not a sensor to drive it.
