Submission + - Robotic umbrella forest to keep Hajj pilgrims cool (

An dochasac writes: "The annual Hajj pilgrimage is expected to bring over three million Muslims to Al-Masjid al-Nabaw mosque in Medina this year. The dry Saudi Arabian climate with temperatures exceeding 100F makes this a punishing and potentially dangerous event for pilgrims gathered in the shadeless marble plaza. German designers, SL-Rasch, in collaboration with Sefar Architecture, conceived a landscape of high-tech sunscreens that span the 150,000 square meter forecourts, a total area larger than the mosque’s footprint. The 250 convertible umbrellas, each 20 meters tall, are sized to fill the courts’ proportions, converting the open plazas into fully covered outdoor rooms.

These umbrellas open and close on demand to provide shade during daylight, trap heat at night and collect precious rainwater. They are also beautiful, fitting in well with the traditional architecture of Mohammad's second mosque."
