Hazel has a simple method in her Strategies section at http://valkyriecrusade.wikia.com/wiki/User:Hazel*26yeq

Another method and probably the best method is to lvlup a building (mine was Parliament) to lvl9. When your resource storage reaches to almost/full, lvlup that building to lvl10 then cancel it instantly. Do it multiple times and you'll waste your resources very fast.
