I am a student of Universidad Panamericana in Mexico Im reading Industrial Engineering and Im researching about a new technology in the automotive sector for a class of technology in the college.

Such technology is integrated to a conventional Turbo car system where by means of a system of gears that feed the rotation of shaft Turbo, fed the generator of the car instead of the motor directly, feeding the battery and the battery feed the spark plugs , with the benefit of better perfomance Mile/G, and a power gain of 5HP. It can be adapted to any car with turbo.It will be helping with the enviroment, youve less gas emission and more efficiency.

What do you think?
it's a good idea for conventional cars?
It can be sell?
The final customer will buy it if the average cost its about an extra of $600?

If you're using a system of gears to drive the alternator, how noisy is that going to be? Why use gears versus belt drive which seems like it would be quieter and likely have less resistance.

One challenge I visualize is the turbo location is not standard on most vehicles, so to adapt gears, brackets, bearings, etc (same would apply with belt drive) is going to be very much a custom fabrication for each installation. Would you limit the application list to a small number of vehicles at first that all share the same powertrain?

Many newer manufacturers have gone to a system of modulating when the alternator is actually charging, thereby reducing the load on the engine when extra electrical charge is not needed. How does the efficiency of your proposed system compare with the efficiency gains of the modulation approach? Can you create a business case for your design over the modulation scheme that likely is more easily retrofitted to vehicles since it would involve mostly wires and software?

Arguably the highest use of electrical power would be a car at a idling at a long, stoplight in the summer with A/C on, the engine cooling fans on, daytime running lights on, etc.
Since the engine is idling and the exhaust gas flow is low, with the load of the alternator the turbine would probably not even turn.
Which puts all the electrical load on the battery.
Gotta think about sustained worse case scenarios.

Using a turbo to feed the alternator instead of the engine would be extremely counter-productive. A turbo, as it is, is a restriction in the exhaust system. It is the boost it creates that creates more power than it loses through the restriction.

Also the horsepower gained from driving the alternator via a turbo rather than by the crank would be very minimal.
