It's NOT a perfect replacement for a chainsaw, but a reciprocating saw can often be used to cut up logs into turning blanks. A reciprocating saw equipped with 12" wood-cutting blade can handle most of what can be thrown at an electric chainsaw. An electric chainsaw with a sharp chain will cut faster than a reciprocating saw. A reciprocating saw doesn't leak oil, is more reliable, and is almost as fast for most cutting operations.
