Sorry.
Couldn't help it
I totally agree about how hard an electric supercharger would be to make. Unless...
Hey Graph, what if I attached a starter motor to a conventional belt driven super charger. If geared properly you think it could work?

You'd be introducing a lot of complexity for no reason - why not just drive that supercharger off a belt like it was designed ? Not to mention that the starter motor would likely overheat in extended usage, and draws a huge amount of current that your alternator would require engine power to make. We basically use a starter motor to operate a snowplow, and lots of angling and raising for short passes in tight spots can draw down the available power to where the low voltage warning can come on - probably not a big enough alternator to run that kind of set up either.
Lead, follow, or get out of the way

Yeah a starter was not made for continous duty and draws much more than an alternator could output. Plus the blower would be all or nothing. Fine when on WOT.
Belt off the pulley would be proper. If u could convert to electric. then back through the motor, there would be efficiency loss in the form of heat. So it would take more power in than you got out vs. directly belt driven. Only friction loss there.

I just thought of the idea of a electric supercharger a while back when I was using my 18-volt cordless drill. It's run on one small lithium Ion battery and it would twist my wrist if i held onto it. I just think it would be a great idea to create a rechargeable fuel cell which drives a centrifuge. Kind of like a huge cordless drill strapped up to a supercharger on a car. Yes it would take a lot of power, and the space under a hood isnt really big enough. I'm sure the concept will appear in a few gasoline cars in the next decade, but the introduction of faster electric cars will probably kill any momentum it creates.

I dont think it will kill the momentum, the introduction of more and faster electric cars will yield more cheap mass produced high power batteries. The batteries is what we are really stuck on right now. http://cgi.ebay.com/ebaymotors/01-03-Toyota-Prius-hybrid-battery-pack-OEM-G9280-47031_W0QQcmdZViewItemQQcategoryZ33574QQihZ011QQitemZ320008627319QQrdZ1QQsspagenameZWD1V
Honda has said that their hybrid packages will only cost $1700 per car by 2009. That will be a battery and around a 20hp/50 motor for $1700. I dont think that would provide alot of boost but you could get a descent amount. If you set it up to just run at WOT Im sure you could get it to run in the 30-40 hp range for small bursts without overheating. That would give you all the boost you would need instantly with no parasitic loss. Seems to me it would make every other supercharger/turbo setup look stupid on the dyno and the track. Just an FYI the prius electric motor has 67hp and 295 ft-lb!!!!!
