There are two problems with this however. The first is how much power could be generated from a "roll over the crater power station" given that it is not an ideal way to make a power plant. The second problem is the fire crater is locate in a wilderness region remote from people who could use the energy that might be generated. Power transmission lines would need to be constructed which would add to the cost and if the amount of power that could be generated was modest at best the cost may not justify doing anything.
