Osmotic engine - 4 Cylinder version for rotational movement

The latest idea is to create directly rotational energy out of the osmosis engine by using a typical 4 clyinder architecture well known from combustion engines.

We constructed a first two-stroke engine inspired design where Hydrogel expansion / contraction drives the crankshaft to produce rotational energy. Valve controls are done every 90° due to the phase difference between each piston. At the moment, the valves have to be operated by manual work as you can see in the video at the left.

The automation of the valve controls is one of our plans for the future, a schematic construction plan is shown at the bottom, right side.
