Resource mining, large structure demolitions, SFX pyrotechnics for film, television, and stage. Exploratory and scientific rocketry, rescue flares, backup generators, trains, industrial diamonds like the ones on diamond-tipped tools.

Essentially what this guy wished for was a full arrest on rapid exothermic reactions which are used in many manufacturing processes, scientific experiments, and life. Hell, I just checked and technically the process that causes things to explode is roughly the same one used by our cells to process ATP into energy for the persistence of our life (and most other non-fungal and non-plant life).
