You make a good point, but I would suggest that you could easily get around this by burning the mp3 to audio cd format (i.e. converting it first to a wave). By does this with a single song encoded at various bit rates, you could actually determine for yourself what bit rate is necessary to achieve equality on your high end system. I actually think a fair number of people who download mp3's take the step of burning them to audio cd so they can be easily played in the car or the discman. This will change as standalone players (hopefully with quality d/a convertors) begin to appear. B
First, its clear from the cnn article that what they found was simply He3, which is not found naturally on earth, and is instead gotten from the refinement process of plutonium. He4, the much more common isotope, is found in large underground deposits. As far as uses for He3, first on my mind is its use in cryogenics. One of the most common methods of acheiving very low temperatures (down to.008 K) involves the use of a He3 He4 mixture in what is called a dilution refridgerator. In my lab I have something like 30 liter-atmospheres of He3 that I use for just this purpose. Talk about He3 for use as fusion fuel notwithstanding (and something I'm not at all aware of), He3 is already a very important isotope.
