This inflatable skyscraper could save lives in disaster zones

“When it needs to be delivered to remote areas, all it takes is moving a relatively small package that’s already assembled and ready to use…” one of the designers, Piotr Pańczyk, told NBC News MACH in an email. “All that needs to be done is pumping a balloon.”

In addition to sheltering up to 1,000 people, the building could house a first-aid station and even a vertical farm that could help feed its residents. And the designers say that with its tiny footprint, the building would mostly eliminate the need to clear debris from large swaths of land — something that often must be done before large numbers of tents can be put up.

The building’s walls would be made of ethylene tetrafluoroethylene (ETFE), a flexible plastic that can have built-in electricity-generating solar cells. Lightweight 3D-printed metal slabs attached crosswise to these gossamer sheets would serve as floors. Ramps between floors would allow residents to move about within the building.

Skyshelter.zip would extend to a maximum height of 100 meters, but the height and number of stories could be adjusted to fit the need: more helium pumped into the balloon means a taller building and room for more people.

There are no plans yet to build Skyshelter.zip, and not everyone is convinced such a structure makes sense. Ostap Rudakevych, a visiting associate professor of architecture at Pratt Institute in New York City, called Skyshelter.zip a “provocative vision” but said technical considerations might render it infeasible. Among these concerns are securing and transporting enough helium to lift the structure and ensuring that the balloon remains fully inflated over time.

“Helium is one of the smallest atoms, and to date there isn’t a flexible material that can adequately contain it,” said Rudakevych, who made headlines last year when he floated the idea of suspending a skyscraper from an asteroid. “It will slowly leak out over weeks and would need to be replenished periodically, or the tower would sag and collapse.”

Pańcyzk acknowledged the challenges of bringing Skyshelter.zip to life but is undeterred. “With current technology, building this structure would most likely prove to be impossible or extremely costly,” he told NBC News MACH in an email. “But we are sure it is only a matter of time as most technologies we use already exist or are being developed.”
