A company has just developed a new idea to house the homeless; portable shopping cart shelters. It’s kind of a cool idea, and will hopefully help people in need.
From the EDAR Site:
An EDAR is a four-wheeled unit, based on a cart design that provides security for belongings, privacy and protection from the elements. During the day, the EDAR is a compact portable unit with sturdy wheels and waterproof protection. The steering is maneuverable and there is a brake and locking mechanism which ensures the unit will not move on its own.

Looking for all options, this seems workable.
