Yes. There are extreme and costly measures which satisfy
all the stated conditions to a limited extent.
For an usable answer provide:
Temperature of the rod and total heat in ( Joules) available,
the desired voltage and power, and the budgetary constraints.
Sure.
You could use a peltier junction to charge a battery. Not very efficient, but you could do that.

Say you had a metal rod, and somehow it was hot. Would there be any possible way to use something to take the heat from that rod, turn it into electricity and store it?
