Making the Fastest Smelter I Possibly Can

Minecraft Furnaces are very slow, so I am making the fastest Minecraft redstone furnace system that I possibly can. This is the ultimate super smelter for Minecraft 1.17, created in the latest Minecraft snapshot for the caves and cliffs update, we make use of the dripstone lava mechanic to have infinite fuel for Minecraft furnaces. This automatic super smelter is an industrial Minecraft furnace array with 300 furnaces working together to smelt items as fast as possible in Minecraft.

    if anyone actually wants to improve this, here's a list of improvements i could come up with: * add a shulker box unloader at the start of the track * connect the lava bucket farm to the system ( not sure if it was done, or it was manual ) *add item filters to the end storage for blocks *add a way to move the minecarts and hoppers back into the system ( some form of auto crafter added to it? ) * ( could also exchange the lava farm for a kelp farm or a bamboo farm for earlier versions, to make it more automated without the lava farm ) I hope some people actually follow up on this 'mega-smelt' idea :D
