Turbocharger to generator conversion?

Hey, I was just wondering, could we turn a turbocharger into a generator that would produce electricity as water flows into one gate and out the other?  Similar to a hydroelectric generator using the mechanical energy of flowing water through a turbine to produce electricity.

A lot depends on your water source - A turbo expects a high speed flow of gas so it isn't very big.

Water turbines tend to be quite big to extract maximum energy from a large volume of water rather than a fast flow.

You might be better off with a water wheel and gear up the output to drive a generator. The wheel give you slow rotation at huge torque.
Look at "impulse turbines" and the "Pelton wheel" - both high pressure low flow concepts.

Yes, but you'd need quite a lot of water flowing through it and at a fair pressure / head.
What have you got?

A turbocharger has special blade design made to react to a hot gas
and rotate very very fast.

Water wheels are designed to be turned by a liquid and because water
density is 62.4 lb/ft3 that is 815 times as dense as air 0.0765 lb/ft3.

The blade shape of a gas turbine cannot accept the strength and energy imparted by a liquid. It will turn in a sloshing type motion
and stop at any mechanical load where the delicate gas blades
may brake off....

Further a gas turbine electric generator would be a very high speed
and output frequency type compared to a water wheel generator.

In theory you would just need to swap the compressor for a shaft connected to a generator. The turbocharger would be like the blades on a windmill, you still need the actual generator.

In practice it all depends on how well a water stream will turn the blades, it should be but when you're using something for something other then it's intended purpose weird things can happen.
