We’ve previously featured Phil Elkins’ homemade travel trailer that was light enough be hauled by a bicycle. Now he’s turned his attention to creating a portable shelter for the homeless. The result weighs 225 pounds and has a tiny bed, kitchen, and bathroom:
elkins wanted his design construction to be a simple, light weight, water tight insulated box on wheels, built with an area for displaying and selling handmade wares.[...]
the roof acts as a rain catcher. when it starts raining, a valve is turned to stop the flow of water to the collection tank to allow debris to be flushed from the roof. after a minute of this cleaning process, the valve can be turned back on and collect free water. when the tank is full, it has an overflow feature which allows excess water to drain to the ground.

Paul Elkins built this lightweight travel trailer for his trip to the Burning Man festival. It has a roof-mounted wind turbine for electical power, as well as a solar cooker and water heater. It weighs only 100 pounds dry, so he can haul it around with his bicycle:
The skin is 1/4″ flutted plastic like whats used for election signs. This was riveted and screwed onto 3/4″ square aluminum tubing salvaged from an old satellite dish. The base was made of 2×2 fir. The 30″ square door frame, made of 1×2′s was skrewed to the side panel, cut on the sides and bottom. The upper part was left uncut to act as a hinge. The bed hinges in a lounge attitude. On the outside resides an herb flower box, a urinal funnel (sanicans were a ways off) and 13″ wheel barrel wheels on a 1/2″ axle mounted with 1/2″ square tubing made up the running gear. I used 3/4″ steel for the tow bar, A recycled card table for the corner camper supports, and misc this and that. It’s whatever I had kicking around at the time, and that’s how anyone would have to do it if worst came to worst.
