Is there any type of equipment to attatch to a generator so that it can provide a constant stream of power for the ballast of an HMI? It would have to be similar to an alternator of a car and keep a charge, feeding the power consistently. My friend suggested perhaps a computer battery backup/surge protector, however I don't feel that it would perform the task well enough. Any suggestions?

I don't know of any such device. It is the job of the HMI ballast to supply the head with enough power to maintain an arch. Be careful while using HMIs with a small generator. They require many more times the power to fire than they do to stay lit. A small generator will start to choke. Also, the generator needs to be crystal sinc or the ballast flicker free.
