You have an equal opportunity to be right, but not an equal probability. Another factless, personalised comment Chris, Argument from authority is invalid. Just because Bussard said it doesn't make it so. Argument from experience, in contrast, is valid. MSimon has actual experience of running a Navy...

I don't recall what Tesla books I've read, but I got the distinct impression he didn't have a good understanding on conservation of energy. This is the key point. Non-trivial discussion of this is rare. A place to start might be the first half of http://amasci.com/tesla/tesceive.html (up to UPDATE ...

Which book did you read?

He got at least part way there:

You have a specific example in mind, perhaps?

Tesla's understanding of "electronics" was rudimentary. I have read some of his books and he would be laughed at today by any moderately competent electronics engineer. He did the best he could according to his understanding. He was an experimentalist. Perhaps the best in many a year. That said, Te...

Re: Polywell = Navy Advantage

Look at the current global turmoil. It is funded by oil. Spreading the Polywell reduces the capacity of our enemies because it eliminates energy as a choke point. And the next choke point is water: http://www.water.org/waterpartners.aspx?pgID=887 http://www.wired.com/science/planetearth/news/2008/0...

Free Plasma Physics Book

If you treat energy separately from momentum it's really hard to keep the bookkeeping straight.

Better to take the harder option and use quaternions:

I still don't see what the mechanism is to get rid of the 4He that gets re-ionised and re-enters the reciprocation-about-the-centre process. A population will build up which will never be cleared from the reaction regions, if this process is efficient and holds in ions as it is billed to do. Rick e...

Re: They just finished that

The strange thing about this thread is that it's clear the basics are not agreed on. Leave aside the ions and the plasma for a moment. Let's have a simple lab model that shows exactly where the electrons go. That is what Nebel just finished as WB-7, the navy is currently reviewing those results. Th...

We can do just as good a job these days with magnetic field measuring eqpt. Or for that matter in a static situation with field simulators. Once you get a lot of plasma and electron guns etc. things get complicated. The strange thing about this thread is that it's clear the basics are not agreed on...

My apollogies if my misunderstanding is because I'm wading into waters that are over my head. Feel free to tell me so, if that's the case. I'm really just hoping that somebody else who understands better than I will pick up on something here. When I was at college, we used vacuum tubes with patches...

Re: Polish divisions on western front

There were several Polish divisions and brigades that served on the Western front in 44/45. I've never been able to find any reference on how they made it out in 39 to fight on the western front. Any vets that I've asked either didn't know or seemed evasive. One Eastonian suggested they were captur...

Oh helz, I can go with thread drift, I guess... NASA finally admitted the "problem" indicated a few years back when it put out it's doctrine on "Faster, Better, Cheaper."
