The A/C might eventually become gear-driven with the power supplied by the flywheel-integrated electric motor in a full-hybrid. In a slightly longer term, only mild-hybrids are going to retain accessory belt drive.

F1 cars are hybrids and it has become a fuel economy competition. They use a motor/ generator on the crank and another on the turbo that can alternately harvest energy from the exhaust and act as the variation to control boost pressure. Or provide supercharging boost until the exhaust flow comes back up during first acceleration.

The next video was Mercedes Benz's effort

They put the motor-generator right on the turbo; while Renault have a driveshaft separating them. I think the Renault design's MGR will live longer.

This is really good technology for hybrid passenger cars eventually.

BMW is supposed to release one of these (electric-assist turbo) soon actually. In a few years you may be able to buy one from the junkyard and retro-fit the electronics to work with any car.

The only way this would make any economical sense today is if you have very good fabrication skills and a lot of time. Attaching a generator to a junkyard turbo is not too bad if you can make a bracket, you'd need to fit it to your exhaust which is also not too bad, then you'd want to rectify and smooth the generator output and send it through a DC-DC converter that's commercially available. Parts cost could be pretty low but it would take a ton of time.

Electric Turbo, 48V Electrics Onboard New Audi SQ7 | Engines content from WardsAuto
Quote:
The latest addition to the Q7 lineup is the first series production vehicle to receive an electric turbocharger to boost the power of its engine, in this case a new 429-hp 4.0L V-8 diesel that also is destined for the fourth-generation A8 sedan and a new top-of-the-line Q8 CUV, both under intensive development here.

An electric supercharger is a step forward but not quite half as cool as an electric/ exhaust turbo which also harvests electrical power.

In the '80s, while developing a turbodiesel 1.6L ceramic engine, Isuzu fitted it with some sort of exhaust-driven "regeneration" system that could harvest about 11 to 14hp with a small generator integrated to its turbocharger.

BMW showed an electric turbo a few years back. It was one of three (turbos). It harvested energy in one direction and compensated turbo lag on the two big ones the other way.

Spindy but doable on oure scale

Saw the early post and remembered to call Turbonetics.
Verified I my hypothesis that we can regulate shaft speed to a specific max rpm 30,000 was an achievable goal, with a waste gate or vgt.type turbo-charger ,teck support realized what I was asking when I referenced the BMW and Mercedes F1 Split Turbo power generation units unfortunately Turbonetics dusen't offer any 1st of 2nd gen cummins parts anymore use to have manifold to exhaust tip. He referred me to his friend at HTturbo.com. I'll call them soon.
I still think that a NA or compound setup would be wise for prototyping

2028 Extreme 800Kv Brushless Motor
This 10hp RC motor is rated at 12s (series x4.2v =50.4v x 800kv = 40,320 rpm and a max rpm 45,000.
10hp burst( 60sec)how long do you expect to be wide open this seems long enough.
with the standard 50% derate for continues is a potential of 3kw of recovered electricity .
Dreem big chisel down to reality
Chiping away
Ps Roster the link is not working says under construction.
