  1. Re:Russia's ressponse was reasonable and justified on Russian Invasion of Georgia Might Jeopardize Space Station · · Score: 1

    Very well put. While I have to say that it is certainly not in the best interests of the USA to allow the continued invasion of Georgia, I certainly feel that the Russians had the right to do some retaliating. That being said, I think there is no need for the Russians to target civilians. Simply crush their military bases to show them who is in control. Also, while this is unconfirmed, Russia's supposed attacks on the oil lines into Turkey seems unnecessary, they are simply risking antagonizing the rest of Europe into actually doing something.

  2. Re:Don't want to dilute the elixir on Apple Files Suit Against Psystar · · Score: 1

    voltage is only half the battle when it comes to power. P=V*A. It could easily have the 5V spec but supply to little current

  3. Re:I call bullshit on Successful Cold Fusion Experiment? · · Score: 2, Informative

    Actually the coulomb barrier is significantly higher than 10keV. You hear this number thrown around a lot because about 10keV to 15keV is the most efficient temperature to run a d-t fusion reaction at to get a significant number of fusion reactions and maintain a reasonable confinement time. For the d-d reactions that this article is talking about, reaction temperatures must be about 50-100keV because the fusion cross section of the d-d reaction is much smaller than that of the d-t reaction. This article in no way states the amount of helium 4 particles produced nor the amount of deuterium that has been burned. They merely claim that the presence of the helium points to the fact that reactions took place, the same claim that cold fusion proponents have been making for the last thirty or so years. The first time this was claimed it was proved that the measured quantities were merely background levels, and I believe this will prove similar. The refusal to report levels of 14 MeV neutrons produced, which happen about 50% of the time in d-d fusion, leads me to believe that these guys are full of crap. A final note on cool fusion, muon catalyzed fusion is currently the only respected method of achieving fusion at lower temperatures. This is because the muon is so much more massive than an electron that the hydrogen isotope appears to be charge neutral until they are very close to one another, at which point there is already a significant chance for tunnelling. However, the energy cost of producing muons is so high that until a better method is found, there is no commercially viable way of using muons in fusion.
