Monorail made from wingless airplanes

Dan sez, "it remains to be even prototyped, but this company has plans to convert old airplane fuselages into hanging monorails."
# The actual Tram car is constructed from de-commissioned Boeing 727's, 737's, and 757's that are stripped of their wings, engines, and tails.
# The fuselages become compartments equipped with solar cells and battery storage.
# These compartments are attached to a rail system by permanent magnet regenerative motorized wheels.
# Power is provided through solar electricity, wind power, regenerative breaking and fuel cells.
# The system of single rails is hung from suspension cables, made level with support cables.
