Via Inhabitat, here is an interesting design thesis concept from Meidad Marzan, who proposes a solar shading system consisting of servo-controlled rotating panels with photovoltaic panels on one side and OLED panels on the other. They charge during the day, and flip around at night to emit light. Marzan also proposes some alternative uses for the mechanical aspect of the system.
I always love to see new thinking and exploration of intergrated media + green systems into architecture. And part of me really likes the aesthetic of this student’s proposal. But the other part of me would love to see the system redesigned to eliminate the actual mechanical movement. Servos simply wear out, and maintaining them are cost prohibitive. No amount of engineering and wishes-for-cool-future-tech will change this fact.
