== Gravity fed drip irrigation, with the intent of complete, hands free automation. == Welcome, you've arrived at the Global Goals clubs challenge WIKI. We ask you to see this as a possible starting point to a new beginning. We hope to prove to the world, that if we use the SDGs as a guideline, a starting point in the search for simple solutions to impossible problems like poverty and hunger. If each of you reading this works toward even one small answer, the millions of small steps when combined into big steps, could be enough to change the world. We view Appropedia as a playground for people who love to try new things. We beg you to look around, find something which would make life simpler for those in need and make it better. We know there are better ways to do almost anything, maybe you'll find some of them. What follows is an example of a simple yet effective way to create an abundance of fresh vegetables in a small space with minimal resources. See it as an example for the challenge. We ask you to create a wiki about your project and keep the world informed of your status. Our wiki is free to to copy and improve upon! We used off the shelf products at a normal prices, but are searching for ways to replace them with home made versions, preferably from recycled plastic. We challenge you to prove that the world can still be saved, we simply need to begin. Find a way to mix cheap modern technology into the SDGs to answer as many of them as you can. The project below attempts to answer problems within a multitude of SDGs simultaneously. At the end is the begin of an outline of possible improvements which could be created to enhance our garden or go off on a new tangeant. Goal: To prove that by mixing fresh vegetables with science, recycled plastic, computers, computer networking and social skills, the poor starving people of the world can be fed at a minor cost, weighed against the benefit to mankind. The garden and ideas demonstrated here are in the public domain, free for anyone, anywhere to use. In exchange we simply ask that you find a way to help in reaching the Global Goals and especially Zero Hunger by 2030!''' [http://www.globalgoals.org/ This goes to the global goals!] === Intro === Welcome to our garden! What began as an experiment, has turned into a working garden which can run alone for several weeks at a time using rain water. The garden presented is small scale, approx. 30 plants, but can easily be expanded simply by adding more branches from the above ground tank and filling it more often. It's main purpose was to eliminate the carrying of water, eliminate guess work and wasted water, while ensuring that the harvest is never at risk due to lack of water. The main benefit was that the automation worked so well that a 4 week vacation could be taken in the middle of the growing season. Only 3 things limit its effectiveness; drought, pump outage and overly dirty water. === Our greenhouse drip system === 20 Square meters, 4 x 5 Not heated, so does freeze at night in the winter. ==== [[File:DripGarden2.svg|thumb|center|Simple representation of the system]] ==== === Parts List === Since we have no more water pressure than gravity gives us, it only needs to be watertight. Here's a list of the parts we used, but we've begun to create 3D printed alternatives to reduce cost. * 1 X 4000 liter underground tank (could be any size) * 1 X pump (can be human/wind/solar or anything else powered) * 1 X 100 liter above ground tank (again size unimportant) * Hose - Enough to get the water out of the big tank and into the small one * [http://www.gardena.com/ca/en/water-management/micro-drip-irrigation-system/l-joint-13-mm-1-2 4 X 90° 1/2" tubing connector] * [http://www.gardena.com/ca/en/water-management/micro-drip-irrigation-system/t-joint-13-mm-1-2 3 X 90° 1/2" T tubing connector] * [http://www.gardena.com/ca/en/water-management/micro-drip-irrigation-system/t-joint-13-mm-1-2-46-mm-3-16 30 X 1/2" > 1/4" reducer T's] * [http://www.gardena.com/ca/en/water-management/micro-drip-irrigation-system/adjustable-endline-drip-head 30 X Drippers] * [http://www.gardena.com/ca/en/water-management/micro-drip-irrigation-system/connecting-pipe-13-mm-1-2 1/2" tubing - enough to reach all plants] * [http://www.gardena.com/ca/en/water-management/micro-drip-irrigation-system/supply-pipe-46-mm-3-16 1/4" tubing - enough to reach all plants] * 1 X Sand and Gravel filter made from: (links to follow later) ** 1 X 30 liter tank with screw on top ** Gravel ** Small stones ** Sand * About a million connectors of all makes and models === Replacements === The following files are on a slow server.
