Could a dark matter particle discovery have practical applications?

[leftyguitarjo]

So you discover the dark matter particle... Now what?

When, or if we ever discover the dark matter particle, how can that knowledge be applied to every day life? Fermi's nuclear reactions allow great fuel sources and weapons to be built. And Hubble opened the door to the universe. Will this "dark particle" even have any significant impact at all outside a bunch of geeks like us?

It may and it may not.

Although I would imagine that such a discovery should be monumental (though I may be wrong!) because it may enhance our understanding of EM and gravitation interactions.
Hey, who knows it may even lead to solving the mystery of life? Completely speculative because it may lead to anything.
