Re: Michio Kaku on FTL Travel
what I like about the theoretical physicist, Hal Puthoff is that he has one foot on the ground. I'm not sure that Dr. Kaku has either foot on the ground. For one thing, If you somehow managed to liberate that sort of energy, how would you channel it? then there is the phenomena of education not making you a good person, it just makes you an educated barbarian.

The great thing about recognising the hierarchical nature of physical phenomena is that one can work from a level where it is clearly possible to see what is happening, to a level where there are only instrument readings as a guide. Frank, the mention of the hydraulic jump took me back to page 300 of my favorite book on hydraulics by George Russell, Professor of Hydraulics , MIT, Oct 1941 and there it was !!! Reading again of the phenomena brought to mind some interesting experiences in designing for large flume flow measurement and the havoc the HJ can play on an unsuspecting lad that wasn't listening carefully in class but later paid dearly for a first person education on the matter. The profound importance of your observation of the CF/HF resemblance to the phenomena cannot be overemphasized. I didn't see it, I sensed it but elusive thoughts can play tricks on the meditative process so I discarded it. Thanks for the clue. One puzzle we have is how to cut character into the mixing dispersal exit cone in order to create a pattern that properly directs the mixed oxidant within a non standard regime. BINGO !! IDEA !!!. Create a hydraulic jump to induce the desired shape of the liquid discharge pattern. Hopefully ,your post may trigger another mind that has CF on the brain < grin> Richard
Re: Engine claims to recover low-grade and waste heat
Thanks Mike in a that case they're onto something. We had a company in Brisbane with a pnumatic linear generator of similar design but they seem to have drifted from sound science to oblivion; the web sites gone. The fast way to kill a good engine is to claim you can tap ambient heat! They forgot to look up the laws of themodynamics again I guess.

Re: Are Fluorescent light Bulbs OU ?
One comment from the Slashdot thread - perhaps of interest to Jed Rothwell, "I have one [Fluorescent light Bulb which stays lit] in my bedroom here in Japan for the last four years." "I t is a ring florescent tube that glows like a night light after the light goes out. The light is made by NEC and is called Hotarukku (a play on the word hotaru, which is Japanese for firefly). It seems they launched the product in March 2000. http://www.nelt.co.jp/navi/la_shg/fre_shg.htm [nelt.co.jp] gives specs and has some pics showing the room lit with the light on and off. Needless to say another "bright idea" from Japan... (both corny and plagiarized) Jones BTW the active material appears to be **strontium** this has potential implicatations for both the experiments of Harvey Norris and BLP.
Re: Are Fluorescent light Bulbs OU ?
Vortex is known to be "forward thinking"... most of the time. This particular thread from last month about "Fluorescent light Bulb OU" appears with a new twist this weekend on Slashdot, which picked up this MSNBC story on the fluorescent light that continues to glow for over an hour after it is turned-off...

The analysis involves the nature of head-on elastic collisions and in particular the case of a light projectile hitting a heavy target.

Hydraulic Jump
I have been pondering the systemic resemblance between the phenomena of hot fusion/cold fusion and the phenomena of the hydraulic jump. The great thing about recognising the hierarchical nature of physical phenomena is that one can work from a level where it is clearly possible to see what is happening, to a level where there are only instrument readings as a guide. For the benefit of those Vortexians [very few I'm sure ;-) ] who may not know what a hydraulic jump is, I googled a definition. To my surprise the definition which came up was in terms of air rather than water, to wit, Hydraulic Jump A steady disturbance in the lee of a mountain, where the airflow passing over the mountain suddenly changes from a region of low depth and high velocity to a region of high depth and low velocity. Still, since most Vorts are probably more familiar with mountains that I am, the above definition will do nicely. As for the water case, there is an appropriate diagram of a hydraulic jump at, http://www.fao.org/docrep/X5744E/x5744eeo.gif This diagram is rather fitting for this group since it shows a vortex as the transition between the two regions, viz. the high velocity region where the speed of the water is manifest, large scale and one dimensional and the region where the speed of the water is hidden, small scale and three dimensional. Now as a first approximation we may think of the deuterium in hot fusion as being in the high velocity low pressure state in contrast to cold fusion where the material is in a low velocity high pressure state. This will certainly give us the kind of bifurcation we are looking for. It was the natural thing is to start this way with the straightforward macro kinetic energy of nuclei flying around like gas molecules. But thinking about it more profoundly I realised that I had things the wrong way around. The real action in taking place at a finer scale. It is vital to home in on the right level. One level up or down and every thing is reversed. Two levels up or down and you have things the right way round but you are hopelessly off target. It's no good jemmying the door on the fifth, third or second floor flat when the sparklers are on the fourth floor. Now the most obviously relevant levels are electric and magnetic field/flux/flow. The electric field is analogous to the high depth low velocity state since for a charged particle the electric field is isotropic, i.e. the same in all directions. The magnetic field is analogous to the low depth high velocity state since for a charged particle the magnetic field is most definitely non-isotropic. So we can now see that not only does the Beta-atmosphere pressure drop inside the Fluid Phase (using the term Fluid Phase in the hierarchical sense defined in the SST paper) lead to a drop in the repulsive electric pressure between deuterium nuclei, but it also leads to a corresponding increase in the magnetic field strength - the magnetic flux/flow. Nuclei lined up anti-parallel will be attracted to each other - will fuse - with resulting release of mass energy. Cheers, Frank Grimer et resplenduit facies eius sicut sol
Michio Kaku on FTL Travel
He has many good articles. http://www.mkaku.org/articles/physics_of_space_travel.shtml Excerpt: "The first realistic attempt to analyze extra-terrestrial civilizations from the point of view of the laws of physics and the laws of thermodynamics was by Russian astrophysicist Nicolai Kardashev. He based his ranking of possible civilizations on the basis of total energy output which could be quantified and used as a guide to explore the dynamics of advanced civilizations: Type I: this civilization harnesses the energy output of an entire planet. Type II: this civilization harnesses the energy output of a star, and generates about 10 billion times the energy output of a Type I civilization. Type III: this civilization harnesses the energy output of a galaxy, or about 10 billion time the energy output of a Type II civilization."

Even a > single particle alone in a container will collide with the walls > (where there are lots of particles). God point. I think they mean magnetic bottle plasma confinement. Then of course you could argue if thermal heat can be attributed to the heat of the magnetic walls, their vibration. I have heard of temperature of magnetic field (cold magnetic fields) but never in any established contexts. Could this be the explanation? Someone? Maybe another clue is the inconsistency of talking of particle speed and temperature interchangeably. If particles have temperature, then waves should too. I should probably take a course in statistical mechanics before asking more. David
