I just found an old (2005) thread by MetroMPG about a powered trailer.

I was wondering if there was any more thought from the ecomodding community of the merit of such an idea. What situation/application would such an idea be ideal? I'm thinking more along the lines of a trailer assist that would be more universal. i.e.: able to be towed by any standard gas guzzler to help efficiency when being towed. How about a small diesel on the trailer running a generator to power electric drive motors. Like a (scaled down) railroad locomotive.
