This is one of those made-for-Dubai ideas that needs to stay in Dubai.
Of course, it's just a concept, but I can't imagine how much of a tourist trap/club hell sh*t show TechnoMarine would be if it became a reality. It would probably only take a few hours for the first herpes outbreak at an underwater Lavo; No ammount of chorline would be able to keep the mutant STDs in the water at bay. We're talking dozens of people leaving this place with gonorrhea and herp galore. Presumably people would be sharing those fancy underwater helmets after paying the $400 dollar cover fee, which is also just nasty in itself. Some doorman will come to work stoned one day and forget to do his job and disinfect the thing, which is just gross. Secondly, how does anyone drink? Sipping through that stupid space age straw? How does one access it through the helmet? It lacks logic. Instant buzzkill. The only upside of this venture would be playing darts with a speargun. That's just badass.
