That may work in theory,

I don't think that would work in theory either. You are restricting the air intake, making the air do "work" and "work" is never free. The engine would be doing the same or more work to make the same electrical power as a belted alternator.
Same theory as putting a windmill on top of your car. It's not free to push the blades through the air.
Putting half of a turbo on the exhaust side and running it through a planetary gear reduction seems pretty plausible.
Take a look at the
centrifugal superchargers. They use a belt off of the accessory pulley to spool a compressor wheel... just use the same gearing and use an exhaust turbine to spool your alternator.
A broken centrifugal supercharger on eBay could yield some fantastic parts... I really like the idea.
