Infinite Firestorm Wall
If you have a firestorm wall and it is fully
charged, you can make it last forever
without having to turn it off to charge. First
charge your wall fully, then turn it on.
Before it turns off or runs out of power sell or turn off your power plants
until the words "On Hold" appear in the firestorm Icon. Your wall will stay
on forever and will not run out of power until you build or turn on your
power plants.
