I'm taking a wait and see attitude at the moment, Tesla is correct, I have very little doubt about that, but the numbers have to be accurate. Then the problem arises of practical usage, this could mean that previous theories (and we should state that they're theories for a reason) could be turned upside down. Or it could mean that that sub-atomic particles could work under different rules, or laws. Either way I find it extremely awesome that someone's trying, and I'm much happier about this than I am about people trying to reach absolute zero, or create a black hole... That's just not good news!
I'm also of the opinion that many people in the physics community are too concerned with taking the safe route, that they will never take great chances due to the risk of failure. It's something that's been going on for over 100 years, so it's par for the course. I understand the reasoning; no one remembers the man (or woman) who got it wrong. But if don't come out of our shell we'll never expand in the areas of physics.
Physics isn't like other fields, a mistimed step can bury you for life.
All and all this is fairly earth shattering stuff, but if it can only be achieved by particles on the smallest of scales, then I'll never be able to find out of space expands faster than light, and I'll die with so many questions unanswered.
