Natural energy, such as wave power, wind power, and tidal power, is a clean alternative that does not cause pollution and does not run out of resources. However, the amount of natural energy is disordered in amount or direction, so it is not easy to convert it into available energy. In existing natural energy generators, the addition of high volume and inefficiency, such as increasing the volume of the device or increasing the speed of the gearbox, has led to a decrease in the utility of the device. On the contrary, if a power generation device with high energy conversion efficiency can be implemented at low cost, this will provide a great advantage in the field of power generation using natural energy.

In designing such a low cost, compact energy conversion device, a piston-cylinder configuration can be considered.
