wait, is there some way to get coal into this? there's got to be jobs for coal and not just this alternative energy crud.
How about using a pitching machine, which runs off the electricity grid (and therefore off coal)? Sure, it would make more sense to just use the wind power to run the pitching machine in a nice closed system, but we want JOBS JOBS JOBS, not sense. Alternatively, just have the pitchers chuck lumps of coal at them. It's not like they'll hit them. And if they do, it still doesn't matter; it would just be an application of the famous lesson of the famous film "Dodgeball": "If you can dodge a wrench, you can dodge a ball."
