What I would like to do is create fission battery powered appliances. My first thought being a container that you put the batteries in, and turn on your generator. Then, the generator ticks down (an hour, say) and then removes the battery from the container. But I can't figure out how that would work, either. So making a simpler one, where you just activate it, and it takes a fission battery from you, and sets a global timer +60. Then, turning the generator on, it ticks the global down one for every real minute passed.
But I can't figure that out, either. Could someone lend me a hand?
