Fusion Plasma Understanding Expands

03/14/2015 6:54 PM

many scoffed at the idea of harnessing fusion as a power source. they ultimately might be right. recently experiments performed at Princeton( and San Diego) furthered our knowledge of how to contain some of the heat released from plasma during the reaction using magnetic fields. one less mystery perhaps Lockheed wasn't sticking their neck out that far when they boasted of their skunk-works expectations were to build a fusion reactersoon http://www.sciencedaily.com/releases/2015/03/150313171740.htm

I am not aware that anyone is scoffing at fusion as a power source. However, they are scoffing at fake demonstrations of nothing that try to pass as fusion.

LOL! You mean "smoke & mirrors" are still not accepted?

As I recall, the worst evidence I ever saw reported in the news, as a real news report, by a reporter following a young kid who built a water reactor in his shed (or something) a few years ago was along the lines of

"we can tell the reaction is actually cold fusion because the arc colour is purple"

Not fusion....but don't under estimate what a kid can do.

The Radio Active Boyscout is not a myth.

Well, there was that one demonstration a few years back that left everyone gave the cold shoulder to.

That and it has been "just around the corner" for decades and we are still waiting for something that produces more power out than in and that could eventually become a viable product.

Like many solar panel developments we have been waiting so long and there have been many articles and developments that have not met their expectations that it's a case of "well I will just wait and see if a working product comes out of it before getting too excited".

Hopeless cold fusion, meat fusion and purple fusion scams have made this worse.

cold fusion is entirely different. you shouldn't combine them.starting the reaction has never been tough. actually regulating it is the key

That's the point, they commonly get incorrectly grouped together because they have the word "fusion" in the title. Cold fusion scams and backyard fusion "discoveries" that result in nothing real seem to get as much attention on the internet as real fusion developments.

I suppose it depends on what one calls "real". If several people repeat the same experiment over and over, and it "works", say 75% of the time, and radiation is detected (just not analyzed well enough to classify as one kind or another maybe) at say 30 times the normal background for that area, and the radiation always goes away quickly (within 30 minutes), what do you suppose is taking place?

There is even a company getting itchy at the trigger-finger to go public when their version of LENR (cold fusion) reaches a COP of 3 or greater. I know of one researcher with a high frequency of excess heat production (at a middle western university that goes unnamed here) who has shown up to COP ~50, with an average COP of ~25. That means there is over twenty times the heat out as heat input. It may be that the heat is all low-grade heat so far, but it is still what could be considered useful heat.

I suppose it depends on what one calls "real".

I am talking about the ones taking pulse measurements using cheap averaging meters to show an over unity reaction for example. Radiation measurements, no none of that, a purple colour reaction is the evidence of a fusion reaction.

The free energy over unity tinkerers that have jumped on the fusion bandwagon. Zero point energy is so 90's.

I know that is what you were talking about, and I hate it when "science" is degraded to "oh looky, it is doing something, see it fizz".

I remember back in the mid to late seventies we were contracted to move a retired Con Edison, 125 MWatt, generator from the middle of New York City to MIT for fusion experiments. Memory tells me this thing was manufactured in the early thirties.

At the time the explanation of the project was that they were going to couple the generator to an 1800 Horse Power motor to drive the unit to speed and then short circuit it momentarily to develop the temperatures to create a plasma. This was said to be in the realm of 10 Million degrees (F or C take your pick). Then through some form of magic they were going to develop the 100 million degrees needed to complete the fusion process.

At that point they were using magnets and a toroidal chamber to contain this plasma while all this was happening. At that time they were expecting that they would have a commercial unit by 2025. I don't think they are going to make it.

All numbers stated are from memory and could be off by a couple of hundred million degrees.

I would love to see them solve the problem but as of now I am a skeptic and for no better reason than ignorance.

This is a test: suppose you have a so-called macroscopic particle, with residual charge on it, and it is moving electrophoretically in an electric field E with a known current density J. Now further suppose this "collides" with a particle that is quantum-mechanical, and suppose the particle can be opposite charge, same charge, or neutral. It is possible to produce a recoil energy in the Q-M particle that is equivalent to the translational energy of millions of degrees? If not why, if so why? It is another form of inelastic scattering?
