A flexible multi-torus solar island concept

We propose a possible marine platform based on several concentric, flexible circular tori as support structure for floating solar islands (Figure 1). The tori are connected by pre-tensioned elastic bands. The structure will support a membrane deck that can carry light-weight cargo (such as solar panels) in waves. The main idea behind the concept is that it follows the waves to a large extent, thereby reducing need for airgap and offering a cost-efficient marine platform alternative. Several islands can be moored in framework type of mooring systems such as to cover large areas. Preliminary wave-tank experiments indicate that the concept is promising
