Hello, fellow IndustrialCrafters! I came up with an idea recently. As one of the rare species of peaceful players (Actually, I play on servers without monsters so hunger still applies), I find it hard to acquire bonemeal, which I would very much like to have. My little answer was: Algae. What is new: -Four types of algae are added to the world generator. ->Algae can be blue, green, yellow or red. Their colors are directly linked to the biomes they appear in. -Algae are rather rare and appear more commonly in deeper water. -Algae behave like underwater reeds: They are still water in terms of "can I swim through and drown" and require water to be placed or grow into a block. When harvested and surrounded by source blocks, they turn into a source block (not to generate a current when harvested). ->Algae grow better the deeper they are planted. If they are planted above sea level, they will, for instance, not achieve heights over 2. Bedrock-level farms will stretch 10 meters high. -Algae grow in the (relatively) dark, but light won't hurt them either. What to do with it: -Any four base algae items of the same color can be crafted into an algae chunk. ( Maybe : -Any one base algae item can be cooked into roasted seaweed for food... Sushi?) -An algae chunk can be used in the compressor. This nets respectively colored mineral chunks. -Mineral chunks can be macerated into dyes, I suggest a 1:2 ratio but, as with all numbers, these are just suggestions. -Two algae chunks of two different, mixable colors can be crafted into two same-colored algae chunks of that mixed color. ->Blue algae chunk + Red algae chunk = 2 Purple algae chunks -Four algae chunks of the four base colors net 2 white algae chunks. Macerate these into (industrial) bonemeal! What does it achieve? -Adventuring: You will have to find these rare algae first. -Aesthetics: Underwater areas with algae will look nicer. -Bonemeal farming and dye production: Finally build that huge colored thing in non-green! Also, fertilizer. -Expandability: Algae are very useful, right? You could expand the idea with more recipes, such as food or energy. Think of bio-hydrogen, plant fuel, or even a substitute black algae dust for making solar panels? Black algae aren't in my suggestion (yet), but they could be a super-rare, fifth base algae type. Algae can purify water, be used as medical items or as an alternative source of paper! -It fits the style of IndustrialCraft - a new-ish, fairly futuristic way of exploiting nature to one's benefits. Thanks for reading! I just hope underwater plants are technically doable. What do you think?
