The main problem I am going to have with this design project getting the water from one side of the room to the other side. one of the main problems will be attaching the piping to the roof as well as making the artificial rain spread around.
some ideas i had were very basic, such as just putting plan piping in and letting that sit at and angle so gravity would push the water down the pipe in to the tank,but i thought about the general area in which the water would try to hit the tank and how well the water would spread. Then I thought of how many different farmers get water to there crops and how the contribution above spreads the water around. this then inspired me to make what i know call the rain maker, the device above simple pushes along a main tube and the water exits throw a nose somewhere along the main tube. so all i did was get a pbc pipe and drilled holes in the top thinking the water would shot out at a strong velocity. I was wrong, the water dribbled out and didn't spread very far, so to fix this i have gotten copper wire and weaved them throw the holes so know the water dribbles out on the the copper wire and down on to the soil giving us a very big range.
