[Gandalf_The_Gray]

Just read the complete story at the media web site. Flash fire only makes sense if someone opened the door. Given the injuries that would have had to have been the wife, he was not injured.

Something does not smell right, a small bottle of powder solvent is not going to blow down half a house and move a concrete patio slab. Wife was outdoors, he was inside when something very energetic let loose. Sounds like the fire marshal is busy shoveling "horse byproduct" over the unlikely event.

Powder solvent is probably pretty close in energy density to gasoline. Dynamite has an energy density of about 7.5 MJ/kg. Gasoline has an energy density of 44.4 MJ/kg. So, pound for pound gasoline has more than 6 times the energy of dynamite. However, gasoline is not an explosive and dynamite is not a fuel, so they serve purposes that are mutually exclusive for the most part.
