Once more we venture into the future via the past, this time through a 1936 design by Westinghouse engineer N. W. Storer. It depicts Manhattan's skyscrapers connected by tunnels high in the air -- essentially subways in the air. Would that make it a supraway or a hyperway? Either way, we've managed to keep most of our elevated trains out of the sky tunnels so far.

He wrote for the smallest of small-town newspapers before finally becoming a full-time science writer and podcaster. He’s currently a senior writer at HowStuffWorks and has co-hosted the science podcast Stuff to Blow Your Mind since its inception in 2010. In his spare time, he enjoys traveling with his wife Bonnie, discussing dinosaurs with his son Bastian and crafting the occasional work of fiction.
