Where Pneumatic Tubes Rule

(From Time.com -- By Jason Spingarn-Koff)

The coolest part of Hammarby Sjostad, a new eco-neighborhood of Stockholm, is the trash.

It gets sucked through pneumatic tubes -- at 43 mph -- after residents drop their household waste into special chutes -- one for food that will get composted, another for paper to be recycled and a third for garbage that can be burned.

As the latter gets incinerated, the energy produced is converted into district heating and electricity.

The goal is both to keep garbage out of landfills and ultimately to produce half the neighborhood's energy.
