RSS - Rotating Sun Screen

Using the effect that you are able to look through a fans blade while it is turning and becoming transparent this concept will be a new type of sunshading device. Having a 50 % transparency on the rotating discs it appears nearly invisible under rotation, but the sun energy is taken out. Due to research tests the amount of light and energy that will pass the discs will be the same in standstill and under rotation. The black areas around the discs will be filled with PV Cells so this device will create transparency when the sun comes around by itself.

The sunscreen will not the solution for all but offers different possibilities compared with current solutions.

The Mock up shows the first proof of concept. The pattern of the discs and the layout can be choosen freely depending on the desired design.

The next developement will be a solution that includes two dics that are controlled by the speed of rotation overlapping each other. So a range from 50 - 100 percent of coverage is possible by changing the speed of the rotating disc (see picture with technical principle). The second part of the video shows a working principle of the adjustable sun screen but without the mechanism that controls the overlapping. In this case the principle shows the different states of shading randomly. In the final version which needs more precision tooling and manufacturing processes the transparency will be adjustable seamless between 50 and 100 % shading.

To get a better impression watch the video.
