Ok, was able to read it finally thanks to the archive link someone posted below. Yeah the "vaporizing" part is definitely wrong, as is the C4 comparison. It's pretty easy to figure out how much energy is involved. It's just a matter of multiplying the volume of the interior by the external pressure, in this case I don't know the exact dimensions, but the inside looks like at least 48" wide by 10ft long. You'll end up with a number around 100 million foot-pounds, or 135MJ. (Or, for a more meaningful number, about the energy released from burning ~3 liters of gasoline). Still an enormous amount of energy, and enough to turn people into tiny little pieces, but it isn't going to literally convert you to ashes like the article implies. It might barely be enough to boil 1 "person's worth" of water under ideal conditions.
