Solar Bell, a kite-like wind sculpture made of lighter-than-air materials — carbon fiber tubing and paper-thin solar panels — by Argentinian artist Tomàs Saraceno, in association with the Aerospace Engineering Faculty at TU Delft, The Netherlands.
The design of Solar Bell is based on a model of a modular tetrahedron, or four-sided pyramid, invented by Alexander Graham Bell during his early investigations into manned flight. Bell made important discoveries in the field of aviation and frame construction, and happened upon the strongest geometrical structure in the known cosmos—the octet truss—the same space frame that Buckminster Fuller later followed in his Geodesic dome. Saraceno breathes new life into Bell’s legacy by using the materials and knowledge of our time.
An invisible but universal phenomena, huge wingtip vortices can be seen in the twisting fog as this airplane lands in Zurich, Switzerland. Wingtip vortices are strong spirals of air that are created when high pressure air below the wing spills up around the top of the wing, a relatively lower air pressure space, making a small horizontal tornado.

Set to Gustav Mahler's symphony number 5, watch this recently released compilation video of Dutch artist Theo Jansen's wind-fueled kinetic sculptures. He calls them Strandbeests, “beach beast” or “creature” in Dutch.
What are the names for the clouds you see when you look up in the sky? In this video from Nova PBS, learn about nimbus (rain), cumulus (heap), cirrus (curl), stratus (layer), and other types of clouds, and why both their height in the atmosphere and their shape matter.
