A crash course in changing the world.
In the average house water is wasted. Most Americans use 100 gallons of water a day. Yet in the poorest parts of the world, people survive on 5. If we could streamline our water intake, we could help the world make more food, cleaner, and (obviously) less thirsty. We can easily do this by reusing our own house hold water. This would start with a filter under the house, powered by gravity. All of the water in our house would drain into it, making it perfectly clean. Then, a pump would pump it into our walls. Surprisingly, it turns out that water is a particularly good insulator. Than, if we wanted water in our sink or shower, we would turn the handle and the water would come out of the wall into the spigot. We could also collect extra water by having the rain water collected in our gutters run into the filter too. All around, this system would streamline our water intake, so more of the world can have water.
