Maybe it will make a dent in the turbonator market.

 

Sounds like an awesome way for BMW service departments to make money. Very German. Make it as complex as possible. It's why they lost the war (twice).

I think I'll let it mature for 20 years or so.

 

whatever happened to the belt driven turbocharger?

I think this is a step in the win direction for small motors.

 

whatever happened to diagrams drawn on a computer in year 2011 and links to the source/patent.

 

When I posted this I was somewhat skeptical like Brain hence the turbonator comment. Hell I could reorganize the geometric shapes and patent a dash mounted fan. Nonetheless i found the regenerative nature (alternator function) of the turbo interesting.

 

Whatever happened to Garrett's patent on the same thing?

What I see that's different is the presence of the clutches.
Look at high load condition. The motor acts as an alternator to charge the battery and prevent over-speed. Now what happens when said German Bahn Burner has been running flat out for a while, the battery is fully charged, and the car has minimal electric load? How do you prevent over-speed now, without a wastegate?

 

Charge a capacitor and ha e it discharge to an electric motor in the transmission when you hit a button? ,

 

just short the alternator output

 

I think you're right Jason. We obviously need to add a brake. There needs to be more heat to promote lack of longevity and keep those BMW service departments going.

There are things I love about German cars, but their propensity for complexity isn't one of them.
