Hi pete c,
Using the alternator that comes on a car will be expensive. The alternator makes AC. To drive it as a motor requires an AC driver circuit capable of delivering a 3 phase ac signal at the right frequency and higher voltage than the stator would develop as a generator. It's a fairly simple motor controller if you design motors and are making thousands, but a one-off will be daunting. In addition car alternators are not designed to be efficient. Low cost and durability are more important. For this idea to really work you need a motor-generator designed for the job.
