I don't think Tom meant to imply that it takes 5 HP to drive a basic automobile alternator. While 500W is fairly typical of generator age technology, the typical automobile alternator today delivers something more in the range of 50 to as much as 100A for larger automobiles. This is more like 1.2kW and would need more in the range of 2.0 HP to drive. Now, for long-term reliability one would want to very conservatively load the engine. So running a surplus 5 HP lawn tool engine at about 40% power doesn't strike me as very unreasonable for the goals stated.

A query Tom, a 5 hp engine will deliver 3.7 KW. Auto genertors are about 500W. It doesn't sound very efficient.
