Copper fans are made from 3 copper blades and the drop from the breeze. Copper blades are made from five copper nuggets in a P shape. The copper fans powered by redstone levels would determine the strength and distance it would push the mob or player. A power level of one would push baby mobs and players the level of jump boost. Level five would be able to push small animals and give the player up to a few more blocks. Level 10 would be able to push more bigger mobs like zombies and creepers and push up to around ten blocks. Level 15 can push things up to wardens ravengers and iron golems and can push up to around 20 blocks for light mobs and 10 for heavier mobs. This feature would be most helpful for bigger spawn platforms for mob farms, parcore for bigger jumps, for elyras to gain distance without using fireworks and also offer a speed boost for elytras. They can be placed in any direction a piston can be in. The more oxidised it is the more it slows down the blades which means it needs to be cleaned like real fans.
