If you were to read the articles on Wikipedia and around the web in general regarding cold fusion, somoluminescence, and other "cold" fusion reactions you would come away with two very wrong impressions. First would be that these technologies are very close to fruition and second that they are the holy grail of energy production and the answer to all of our problems. You would think that the fusion reactions are not dangerous, do not pollute, and the fuels involved are of infinite supply.
The reality is that the only reproducable, controlled, fusion reactions mankind has managed to generate in a reproducable manner consume much more power than they generate, and are many, many years before becoming a source of power.
Regarding fusion by-products, the fact is that most fusion reactions produce deadly forms of radiation, weather "cold" or "hot", and the fuels required for a-neutronic reactions are not in infinite supply.

Granted that the idea of "Mr. Fusion" powering our automobiles on flat beer with helium, water vapour, and heat as it's only waste is captivating. Having a near infinite supply of energy would solve many of our and the world's problems (and I'm sure cause many of it's own as well).

We should not lose sight that there are real, proven sources of energy that are renewable, cleaner and longer term than fossil fuels, that also require our investment of research, money, time, and education. Although they are not a "Magic Bullet" like Cold or Bubble fusion, they are the reality we should be focused on.
