It appears to me that American ingenuity has created a new bomb. It's been all over the newspapers and TV, but it needs a name. It consists simply of an empty building and an oversupply of odorless, colorless gas, which accumulates from some irresponsible source.
Superstorm Sandy gave us a lot of empty, unattended buildings and irresponsible sources. We saw at Breezy Point a whole neighborhood bursting into flame. More recently in Indianapolis, it was an explosion which devastated a large number of structures.
These are not simply cases where someone forgot to turn off the gas. The tremendous amount of property damage has insurance companies in a panic. Fortunately, loss of life has been limited. Gas explosions are nothing new, but the frequency and scale has gone off the chart. One clue seems hard to dismiss. If your water smells bad and you can light it with a match at the faucet, you just might be vulnerable.
