Origins

Visualization of an early energy-harnessing concept. The cell walls incorporate Dielectric Elastomers or other electroactive polymer materials capable of converting mechanical strain into electrical energy. In this view, water is flowing towards you through the cells. The net strain in the system remains roughly constant under operation as elastic energy is swapped between cells. The net flow of water also remains constant.

Can I get some context? Is it some kind of propulsion system?

Its actually an early energy harnessing concept. The walls incorporate dielectric elastomers or other electroactive polymers capable of converting mechanical strain into electrical energy.
