Renovated Airstream

As the owner of a restored 1952 Silver Streak trailer, I am always interested in what other people are doing with their old trailers.

This one showed up at AltBuild in Santa Monica a few weeks ago, using "green" building elements.
Notice the strip of solar wrapped around the trailer.
The owner plans to keep the trailer entirely off-grid although I see that even green people need a TV. Hmmm.
Way to go, I like the thinking.
