A:
In principle you can produce electricity from any heat source.  The problem is that it's not straightforward.  In the case of a camp fire you could heat up some water, make some steam, then run it through a turbine generator.  You wouldn't want to take all this extra equipment on a camping trip.

You can also get small thermoelectric cells that generate electricity if one side is hot and the other side is cold. These would work if you could keep the side away from the fire cold by  keeping it in contact with a pipe with cooling water running through it. It's still simpler and lighter than a turbine generator.
