You also have to consider that the reason Dust doesn't hurt people is because of their Aura. However look at it from another POV. Even if Dust isn't that strong against humans, Hunters will use Dust-based weapons against Grimm because they don't have Aura to protect themselves from it and it is even said that the discovery of Dust turned the tide of war. This means that Dust is very powerful by itself, just not against humans (or at the very least, combat students).

However if you wanted to power your car for example, unless your car has an Aura it should run normally as the Dust used would release the same energy, but the car would take in more as there is nothing blocking the intake of energy.
