The energy comes from starting it spinning by hand. The weights around the rim provide momentum so that the small amount of friction from the bearings takes a long time to slow it down. I believe it could spin for a month, but that just means it took a month for the friction to equal the force of the initial push.Once you attach a generator or any way of taking energy out, it will slow in a shorter time. All the energy that you gain from gravity pulling the water down on the left is used up dragging it up against gravity on the right. There's nothing left over and nothing new created. Once you connect a bulb, it will light for no longer than it would if it was powered by a battery with the same energy as the push that started the wheel moving.All the energy in the system comes from your breakfast. The flywheel just stores the energy you put in. When you take the same amount of energy out, the wheel stops. (And you won't even get the full amount of energy out because some will be lost to friction.)Show lessREPLY18</blockquote>
