It is a fish tank that can auto- clean itself. It is powered by a battery that can charge itself, that powers the water cleaning system that then powers the mini dam that gives energy to the battery and continues infinitely

Little Inventors team says

Marcus, you have invented an infinite energy machine, wow! This self cleaning fish tank looks like it will save pet fish owners a lot of time and effort, because it will just keep itself ticking over infinitely. I think the system you have to power the self charging battery is smart, using the water already in the fish tank to power the dam, ingenious! Great work, Marcus, keep on inventing!
