Hot on the heels of the Paris climate talks, one man is proving how far we can go with a little foil and air.
Argentinian artist Tomás Saraceno sent his orb prototypes up to the ceiling of the historic Grand Palais in Paris, where they don't need engines or fossil fuels to power their movements.

His nonprofit project, called Aerocene, involves a series of sculptures that fly sustainably. Each sculptural orb is made out of thin foil, filled with hot air, and its height can be controlled by releasing some air. During the day, the sun heats them up. Saraceno's project page insists that we don't need violent explosion to reach the stratosphere.
"Aerocene begins now as a past-becoming-future technology," he told Dezeen. "In the near future, it will define the age of the post-fossil-fuel travel, a pace of living that is in tune and at the whim of the wind."
Saraceno definitely has his head in the clouds - in a good way. He often plays with the idea of floating or bouncing in the air. His Cloud Cities transported museum-goers above the fray. For "On Space Time Foam" he transformed a former factory into an enormous interactive space where visitors moved around on transparent plastic sheeting suspended at various angles.

And, in case you were wondering, Saraceno is indeed planning a balloon trip around the world. He wants to fly a fleet of these orbs that's powered without any fuel, hydrocarbons, helium, solar panels or batteries, Dezeen reported. Although I'm not sure yet if his trip will take 80 days.
