-Water filtration-
A way to get higher quality water. You make a still, one of several types of differing construction and quality (I'll only point out 1 method for now).
purifier mix:
2/3 sand, 1/3 charcoal, used as the 'fuel' element for the purifier.
the sand water purifier:
A collection of tree bark, branches boughs, a couple of barrels, purifier mix, and two bits of linen cloth. Quality would be determined by the average quality of the built materials, and the quality of the purifier mix. Water is added in to a max of 100 liters, every 10 minutes .1 weight of purifier would be used up, and .1 of higher quality water would be produced.
(still+purifier+water+survival)/4=returned water to a max quality of 50 for the primitive still, higher maxes with less primitive stills.
the primitive evaporator:
1 barrel, 4 linen cloths, and 8 tree barks. A more secure way of getting higher quality water, though much slower. Up to 50 liters at a time. Quality of the returned water is a little more than the average of the evaporator and the water used. Each run of the evaporator would take 5 days, and you would get back only 1/5 of the water you used.
Max quality would be 50 for the primitive evaporator, and the formula could be (still+water+survival/3)+2
-Composting-
A way to get higher quality soil. You make a compost pile, requiring a few sticks and some soil to get started. Anything organic can be placed inside as the 'compost', and the quality of the entire pile is adjusted, like chicken coop feed is now. Organic matter, for the terms of this would be wood, food, leather, intestines, herbs, anything that would decay, and decay quickly. Up to 30 units of soil could be placed in each pile. Each unit of soil would effect thew quality of the pile, Same as the compost for the pile would. When the pile is ready you hit the compost button. 3 days later you get higher quality soil.
formula: (compost average+soil average+farming)/3
-Sand purification-
A slow drain system for washing, and bleaching, that sand to raise it's quality.
Primitive sand cleaner: Made from 8 branches, 4 linen cloths, and 12 strings. Uses water, as it's purifier. Quality of the cleaner is determined by the average of it's construction materials. Will hold up to 10 piles of sand, with more than 5 sands lowering the quality of the output. Requires 2 buckets of water, water is added in as it drips out at a rate of 1 liter per 3 hours. It doesn't refill itself, quality of the sand you get would depend on the quality of your cleaner, the quality of the water you used, and the quality of the sand you put in.
so: (cleaner+sand+average of water used+survival)/4 = sand you get back
-clay purification-
in a fully fueled, and watered cauldron, you take a large quantity of clay, 10 pieces, and boil it for 30 minutes. This boiling would force some of the silica out. this would give a higher quality clay, but with a small amount, 2 pieces, of clay lost per attempt at it.
formula: (cauldron+clay+survival/3)+2
-Piles of 'x'-
Ever run into the problem of wanting to have a load of something around for whatever reason, but not wanting to waste 8 cupboards worth of space to hold onto all that random crap, just in case someone comes by wanting to trade? this could easily be the solution.
wood box: Holds branches, a lot of branches, averages the quality of the branches placed inside and holds up to 50 or 60.
bin of 'x': A bin for plant fibers, cloth, whatever you want to toss in it. The container remains unnamed until you toss something in, then it takes on the bin of 'whatever you just threw in', and averages the quality up to a certain amount determined by the size of the object.
wood pile: A large pile of logs, quality being averaged.
Rock pile: same as above, but for rocks.
feel free to flame me for this if that's what you're going to do, but I feel at least some of it might be useful, or at least fun to build and play with. Likewise it would give the new players who can't seem to find a good spot for these basic resources a chance to actually get somewhere.
