You don’t need to be a rocket scientist to recognize the rocket potential of sitting on a tank that’s pressurized to over 3,000 PSI. Perhaps irrational fear on my part but I don’t particularly enjoy transporting my oxy/acetylene tanks when I need to.
Yet over a hundred thousand vehicles on the road, and decades of proven use won't convince some people. These are not built with thin-wall weak tanks.
You also don’t need to be a rocket scientist to know that the energy stored in a flimsy 30 gallon gas tank is enough to drive a 3,000 pound vehicle made of steel for several hundred miles at speeds of over 100 km per hour.
Life is scary...
(My point is lets cool it on the sensationalism. Let’s trust that the excellent engineers at Westport Innovations, Honda and Ford build the excellent products they are capable of building.)
Propane powered vehicles have been around for years especially for fleets. How often have you heard of one of them blowing up? As long as you don’t break one of the valves on your oxy tanks, they’re safe.
