>> These CNG fuel tanks are made of aluminum and reinforced plastic. Well sure, but whacking a steel tank going over a curb or whatever is a minor 'oops'. Carbon fiber and aluminum are brittle. No thanks. I want my redundancy. It's 3000psi in one of the harshest technical environments we've got. You won't have the equipment to even inspect the thing. CNG doesn't scale well; an automobile-size tank is a bulky, heavy PITA, where a bus-sized (or larger) tank is less of a pain. It fills REALLY SLOWLY too as cramming a gas through a tiny hole jus takes a long time. LNG is an even bigger PITA. Steel tanks are big, stupid, simple, safe. And heavy... $3.00? I now routinely pay $3.60 here in Los Angeles. Oh I bet we ain't seen nothing yet. At least Europe gets public transportation for their $4.50/gal! _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
