Yes & no. If you read up on their history, you find that they were a fairly short-lived phenomenon. The engineers diddled around trying to find the optimum size for the turbo recovery, and discovered that the most efficient solution was to eliminate the IC engine part - and thus the turboprop was born :-)

Shouldn't be any need to mess with complicated mechanical linkages, just use electronics to control the alternator field current, and thus the amount of generation. At idle, no current, thus no load other than a bit of bearing friction.

Would be neat if it could be made dual-purpose, to function as alternator and turbocharger. Instead of a waste gate, you'd control boost by varying alternator load... So where's the aftermarket kit for my Insight?
Thanks for finding that, that's what I was thinking of.

I remember other threads talking about this, but I don't remember a specific manufacturer. Looks like a company to watch.

I remember the other one too, worth yet another repeat. Unlike most of my repeated internet.
between that and a belt driven supercharger where the original alternator went...nice.
