Tachyons are interesting, but again, no experimental evidence for them has been found. Entirely hypothetical at this point. Doesn't stop the new age-rs though; I remember seeing glass "Tachyon beads" in catalogs back in the early 90s. Supposed to make you more attuned to the universe or some such rot. I always found that one particularly funny! Anyway, proving the existance of tachyons would be news as big as this.
Cold Fusion also looks promising these days. There's some stuff going on at the National Ignition Facility (https://lasers.llnl.gov/about/) using lasers to create fusion. That's still a ways off though. There's also the Energy Catalyzer (http://en.wikipedia.org/wiki/Energy_Catalyzer) which has all the markings of a hoax, but it IS performing. I believe one can be skeptical and excited at the same time.
The really big aspect of the neutrino experiment is the potential for growth to a new field of physics. Just as relativity expanded the world described in newtonian physics, we will need new physics to expand relativity. Again, this experiment needs to be replicated elsewhere (I think there's a collider in New Mexico that comes close to the tech at CERN), and we're not anywhere near the tech to manipulate it, but there's potential here. No amount of skepticism can extinguish the excitement of the idea of our view of the universe changing! It's like being in the room when string theory first came about (another concept of which there is no experimental evidence). I wish Richard Feynman was around to see this!
The interesting paradox here is the closer an object gets to approaching the speed of light as it travels, the more it will condense and implode. Once it goes faster than light, the particles can move apart.
