Two containers are connected, divided by a selectively permeable membrane. The continer on the left contains pure water. The container on the right contains water and a negatively charged solute. The container on the right is angeled vertically so that when the water diffuses across the membrane the water level will rise. At the top of the container is a magnet which is also negatively charged. I am predicting that the magnet will filter the negative molecule out of the water as it rises. However, I suspect their will be an issue concerning entropy. Anyway, if all goes to plan the water that was purified by the magnet will leave the container through a spillway. The kinetic energy from the falling water will be harnesed by a wheel. After the energy is harnesed the water is redirected back into the the container with the pure water. Hypothetically this creates a constant flow of energy which is impossible. Whats wrong with this? Please critique and give some ideas on how to improve the experiment. My written explination may be hard to understand and I am going to try and insert a picture to help.
