Zeppelin, originally uploaded by czak142p

While I am all for researching alternative transportation options, the idea of transit by a Zeppelin fleet doesn’t make sense from a holistic point of view. If private companies wish to research and develop future lighter-than-air aircraft, be my guest.
High speed rail, though initially expensive, is both a proven technology and is a cost effective means of transporting both passengers and freight. If you are serious about reducing carbon emissions per ton/mile or per passenger/mile the airship is a non-starter. High speed rail is the proved technology, not hot air.
