as stated in same article in the past these things did belong in the Coral . Now with current technology it no longer is unobtainable.

Using an exhaust-driven generator integrated to the turbocharger doesn't seem to belong in the unicorn corral, but I still consider it more as a complementary source of electricity instead of a replacement for a traditional alternator. The only way to get rid of the alternator in a production car with an internal-combustion engine so far is still a hybrid setup, but it's also possible to keep the alternator and actually use it as an auxiliary motor to provide some mild-hybrid ability like in GM's e-Assist.

As for supplemental power agreed.
As for getting rid of the alt.

BMW’s EfficientDynamics strategy relies on the recycling of normally wasted energy, using electricity as the medium. The alternator is programmed to charge the battery primarily during deceleration. This relieves the engine of the charging load, which, in conjunction with additional electrically driven accessories, yields a worthwhile mileage improvement.

Further evidence of BMW’s enthusiasm for electricity is an experimental thermoelectric generator shown at last fall’s Frankfurt auto show. This device uses semiconductor materials to convert waste-exhaust heat directly into electrical energy, which is also stored in the battery.
Keep it just repurpose it similar to how member of the Community have posted on Ecomodder.com... toggle switch and more complicated. Some go as far as complete removal. Not me with a 200A load @start-up, from Grid Heater, for up to 45 sec. And cycling till IAT remains above 60°f.
The thermoelectric generator could convince me however to do the alt. delete or this discussion makes headway. From a potential parts list consept . To prototype and beyond.

------____------
Funding for me is gonna be really tight for the next year. So for now I am working out the conceptual bugs and building a parts list. And you guys /gals are trying to accomplish the same thing as me . Kill the for see able bugsand arrive at f functional prototype.
I am learning how to communicate In writen Form. This will take time thank you for being patient.

Also as an end game. If and only if we find a non-crankshaft power supply, then we can dust off Browns Gas and pull it out of the Unicorn Coral .

Well thanks for that; but I've always thought that I run hot and cold. So people have to think about what I say, instead of accepting or ignoring it out of hand.

This is not an area of expertise and I don't really care that much, but here is the original story from the 2011 patent.


BMW Patents Its Electric Turbocharger Technology. More Power, Less Lag.

The clutches are at 6 and 7. I think this is shipping in 2016 models but once again I don't care. Audi has an electric kompressor but I think it doesn't do regen.

That explains a lot. You said it just in time, I was tempted to go all Grammar Nazi but now I won't.

The clutch isn't really necessary, it just saves a little bit of drag on the compressor wheel, which doesn't really matter if you're not running at full throttle anyways.

If I ever get a turbo car I want to try DIYing an electric turbo.

You can put a prototype on a non turbo for the $$ because of the prototype failure =new turbo new engine if plumbed as a funnel . When I get to a building point it will be a secondary turbo. Tookeep the bits and pieces out of the engine. Unless we can get past the consept stage.

The only possibility I see for the regular belt-driven alternator to remain widespread in a next generation of vehicles is some integration of it into some sort of KERS, e-Assist, i-Eloop, EfficientDynamic, whatever you may name it. Among the high pressure for an increase in the overall efficiency, including the widespread of start-stop reaching even in the Diesels, one can easily predict that some hybrid-like feature will be present in all the newly-developed cars in about 10 years.

Belt drive is IMO still useful, but in the future it will be just for A/C (electric A/C requires a huge amount of power which is difficult to supply), and the alternator, which hopefully will have evolved into a motor-generator unit. There's no reason why the alternator should be dead weight under acceleration when it can provide extra power.

To the future

cRiPpLe_rOoStEr Agreed
With the widespread and continued development and proof of concept ni BLDC motors/ controllers. BLDC will replace every single crankshaft HP to include the cam most likely a form of linear actuators directly attached to the value no spring . How much more HP can be freed up by removing all that parasitic load ? much more than a 10HP BLDC ,or at least large enough to move the car. A direct drive covering the harmonic balancer. Also makes no more finger traps. This liner actuator idea could open all the valves for Engine Off Costing. The computer can run a downgrade algorithm to control speed.adding valve movement to increase resistance. This would solve the battery full run away problems, that I've experienced with my cousin's '14 Leaf. Or something like what we are developing as a power supply it has a HP limit of 1/3 of the waste heatas a turbocharger as a BLDC spinner who knows with the increased efficiency of direct drive Vs shoving air. Or use a BLDC strong enough to stop/stall the engine disapating the kinetic energy into a supercapacitor and a small bat. to top off the supercapacitor after long storage , instead of letting the energy be absorbed by static compression.
Ultimately the petrol engine has had a Hart attack and is dieing, poor fellow don't even know it yet. Maybe 15 years left as a pure petrol production model ,not accounting for E-85 /B-10 they are already re-engineered for now. And no form of electric motove force aka hybrid, across the board yet. Once we can make enough non-crankshaft electricity., then the sky is the limit on MPGs . 1000mpg is possible. But alas the future is to far away to see yet.
Gumby stay flexible.
PS keep the ideas coming we have 100,000RPM motors everywhere in the RC world. Dose any one know? If we can keep the turbocharger down to <100,000+10% ? With a 1)waste gate. 2)VGT(Verible Geometry Turbocharger )
