What with Global Warming splintering ice caps in the poles and the threat of rising sea levels engulfing all but the highlands, it is fairly reasonable to believe that Herve Jaubert's predictions will in fact become reality. Herve, creator of Exmos, the most technologically-advanced submersibles on the planet, believes that there is a place in the not too distant future for "submersible mass transit" (peeps in subs instead of Boeing aircraft!). "Why not?" I say. Make mine a yellow one with a sick Bose 'in-sub' sound system so I can shimmy with the sharks to John Paul Ringo & George. "This is Yellow Sub One to Sea traffic Control. Do you copy? Over"
