We have all seen the analogy between flow of water and electricity, pressure, flow and restriction being equivalent to voltage, current, and resistance. Yesterday I found an example of a water circuit with an inductor and a capacitor, which performs equivalently to a boost converter. It´s called a ram pump, and it uses the kinetic energy of water flowing downstream to create slow flow of high pressure water.
See this video for explanation how it works.
Now tell my that the water analogy is wrong and should not be used to show how electricity works
