The project I am working on here is a project called Space Ship Earth. Each member of our class designed a ship. First we could just do what ever we wanted, as long as we had places to sleep,eat and use the bathroom. Mine has seven bedrooms,three bathrooms and two kitchens. We have everything you need to eat sleep,eat and have fun. But there was a catch. We will be on the ship for twenty years, and we can not bring twenty years worth of anything. First we had to learn how to create oxygen and get rid of the Carbon D. We decided to make a green house. See trees take Carbon D. and turn it into Oxygen. As you can see, Each tree represents 100,000 trees. Studies show that one tree gives are for two animals. So we will have plenty of air. Next we had to find a way to reuse solid waste. Most can be fed to animals and fertilize. All solid waste is pumped into a tube with goes strait into a solid waste bucket. That gets pumped into the animal pen or garden. Each plant and animal represents 300. We definitely have enough. Now not all things can be eaten or fertilized. We will melt plastic and metal and reuse it. Stones can be placed as bridges. The most complicated machine is the water. This is how it works. There are two glass containers. One is inside another. On top of it a very big plastic wrap. There is a lot of ice cubes on top of it that are kept cold by huge freezers. The ice cubes are in the middle so that there is a drop in the middle. Liquid waste is pumped in two the outside container. The water evaporates, filtering it while it happens. It goes from liquid to gas back to liquid.It goes into gas when it evaporates. Only water can evaporate, not dirt.It turns back into liquid when it hits the plastic wrap. It slides down to the middle and drops into the middle container. That water gets pumped into all the places the house needs it. To speed up the process of evaporation there is huge heat lamps to make it evaporate quickly. The ice makes it turn into a liquid because of the temperature difference. You can also get to the middle container to get water by crossing the stone bridge. That is my space ship!
