I have found a number of crash sites throughout the game. While some of them require only a part or two to fix, a number of them have a line saying "Battery damaged" followed by a wattage requirement. I have supplied the wattage requirement. I have repaired the other parts. If this is something that is broken, can it be fixed? If this is something that I haven't run into the technology for yet, I only ask if that is much later than coal. If anybody else has run into this problem and solved it, what was your solution?
