Vermont city almost encased in a 1-mile dome

A Vermont city once proposed a one-mile dome over its 7,000 residents. (They paid $4 million a year in heating bills, and could reduce their heat consumption by 90 percent!)

There'd be fly-fishing all year, and no more snow shoveling. ("Air would be brought inside by large fans and heated or cooled as
necessary... Entrances and exits would consist of double doors akin to an airlock.")

HUD funding was imminent, and within days the town was receiving
20 bags of mail a day from around the world. (Buckminster Fuller warned their biggest challenge would be keeping the dome from floating away...)

And to this day, the former city planner insists it was a great idea.

"Economically it's a slam dunk."
