Ok, I am going to reply to both soreff and Thomas:

Particle physics isn't about making technology at least at the moment. Particle physics is concerned with understanding the fundamental elements of our world. As far as the details of the relevance of particle physics I won't waste the time to explain. Obviously neither of you have any real experience in the field. So this concludes what comments I am going to make on this topic until someone with real physics knowledge decides to comment.
