    Pros and Cons of Fusion Power Generation

    Yes, about radial velocities, I agree. But I find the part about radial velocities acceptable. I have no access to the full text of the cited paper...

    Pros and Cons of Fusion Power Generation

    With the due respect, Why?

    Pros and Cons of Fusion Power Generation

    In the discussion about the Polywell topic in Wikipedia (http://en.wikipedia.org/wiki/Talk:Polywell), there is an interesting, if intuitive, approximation to velocity distribution in a polywell. Regrettably, the author is unknown: Pity I haven't got the maths to model that intuition. My...

    Pros and Cons of Fusion Power Generation

    Yep, but one can always suppose that Ridder said that in tongue-in-cheek mode. I don't think a jest like that should be used to destroy the credibility of a scientist.

    Pros and Cons of Fusion Power Generation

    Foger, That is a serious accusation against Dr. Ridder. His supposed motives are orthogonal to the actual discussion-the question is if his maths are correct, or not. Best regards. JL Domingo

    Pros and Cons of Fusion Power Generation

    Bussard said that on the video, that collisions between ions and electrons have a very small probability. But I don't recall Bussard publishing "his" distribution.

    Pros and Cons of Fusion Power Generation

    Yep, and Rostoker dedicates a few harsh words to Ridder for apparently using that distribution only for the sake of finding a easy analytical solution, but I didn't see the reason Rostoker gives for using the other distribution. May it be that Ridder used that distribution because "everybody...

    Pros and Cons of Fusion Power Generation

    After posting I saw Journal of Fusion Energy published the infamous results on "less than warm fusion" by P&F. However, they say their standards for accepting papers have improved. Can you follow the math? I'm only a dumb, lazy, EE, after all...

    Dr. Greenman, Thanks for the clarification. Jose

    Pros and Cons of Fusion Power Generation

    Is Journal of Fusion Energy a peer-reviewed publication? If yes, then could someone with plasma physics background tell me if this paper by Rostoker, Qerushi, and Binderbauer rebukes authoritatively Todd Ridder conclusions about the unfeasibility of p-B11 fusion...

    I WANT to build a nuclear reactor.

    Morbius, I'm only a dull engineer but by your definition, all the tokamaks, ICF facilities, etc., built up to date aren't reactors, as they are not self-sustaining. And then the R on ITER should not be granted until it demonstrates that could do break-even AND extracts enough energy to...

    Pspice Help: Plotting VTC of Circuit with Orcade Capture Lite

    With the stock models of transistors, the VTC that OrCAD produces is very "squarish". I think you could take values of VIH and VIL accurate enough from the corners of the charasteristic. However, the true VTC of a BiCMOS inverter is "rounder" and, in the case of arriving to a "rounded" VTC...
