What about a parasol inflating automatically to a cloud like shape using a solar panel at the top whenever the sun comes out and deflating when the sun goes away?
Cumulus Parasol by Studio Toer is similar to cumulus as its name. The Parasol inflates in about 20 seconds. The inflated Cumulus has a diameter of two meters. The cloud doesn’t have a metal core structure. The curved shape of the inflated cloud is aerodynamic, allowing it to withstand windy weather. The nylon surface of the Cumulus is durable, lightweight, and strong.
Solar panels are positioned on top of the parasol. When it is sunny, these panels power a fan which inflates the body of the parasol. When the sun goes away the parasol deflates automatically. Also the parasol can be switched off using an additional switch which is integrated in the pole.
