Inspired by the movie.
Idea by DJCherryTempo.
Place a Fldsmdfr above level 200 and provide it with water.
Place a Terminal anywhere and provide it with RF.
Shift-right click the Fldsmdfr with a linker and the right click the Terminal to connect them.
Provide a redstone signal to the terminal to stop it.
Food rains only in chunks with players.
The more the food is filling the more water and RF is needed.
As long as food from other mods extends ItemFood, it should be compatible.
(For example with Harvestcraft you have plenty of variety.)
CWACOM doesn't contain an RF-generator. You need a mod that provides RF.
Credits: wiiv (model and texture)
Go and fill the world with food.
