Can't work, he wrongly assumes that the inside wall of the hollow cathode will be positively charged (as required to confine positive ions), for some strange reason that he only knows. Michel P.S. Your P.S. is a very good idea though! 2008/10/8 Mark Iverson [EMAIL PROTECTED]: United States Patent Application 20080226010 Sesselmann; Steven Arnold September 18, 2008 Reactor For Producing Controlled Nuclear Fusion Abstract Method and apparatus for producing controlled steady state nuclear fusion with isotopes of low atomic numbers being the most useful reactants, such as Deuterium, Tritium and Helium3. The apparatus consists of a high voltage power supply and a high voltage spherical capacitor, constructed in such a way, that the outer shell is the anode and contained centrally within it, a hollow cathode, into which positive ions of the reactant gases can be injected through dielectric tubes and confined electrostatically within the cathode, until such high temperatures are reached, as to allow nuclear fusion to take place. The interior chamber of the cathode forms part of a hermetically sealed fuel circuit running through the capacitor, a turbo molecular pump is also connected in line with the fuel circuit, to drive the reactant gas through the reaction chamber The fusion product, which is mainly high energy Neutrons, Protons and alpha particles, is consequently converted to heat in the dielectric medium contained within the space between the anode and the cathode, this heat can easily be extracted and converted into useful energy using known methods. -Mark PS: get the f'ing political opinions out of this forum! Wait a minute... Here's my $.02. Anyone who thinks that the Prez (regardless of party affiliation) is responsible for the economic conditions of this country, needs to go back to jr. high school and learn that the House and Senate draft and pass laws, not the executive branch. Okay, now get them out of this forum! :-)
[Vo]:HiPER Fusion
Seems appropriate coming from a hohlraum: http://www.telegraph.co.uk/earth/main.jhtml?view=DETAILSgrid=xml=/earth/2008/10/05/scisun104.xml Nuclear fusion energy project could lead to limitless clean electricity By Richard Gray, Science Correspondent The power of the sun is to be recreated in a new £1 billion science project which aims to provide a clean and almost limitless source of energy. British scientists will this week begin work to create a nuclear fusion reactor, which will use the same powerful reactions that take place in the Sun to provide energy and, ultimately, electricity. Scientists have previously only been able to replicate the reaction inside hydrogen bombs. Now, however, they believe they are on the verge of achieving controlled fusion in a laboratory for the first time. Laser beams with enough power to light up every home in Britain for a few microseconds will be used to heat up the nuclear fuel to millions of degrees centigrade in order to trigger the reaction. more
[Vo]:Guerrilla (Gorilla) marketing
Cervantes may have left us some time ago, but what is that smell? Does it seem odd? - and it not so much here on vortex (where we are careful to avoid politics g as elsewhere) - but it has happened a number of times in the past week on lightly moderated forums: newbies will join, jump into a discussion, seem to have a relevant point or two - and then resign with some kind of gratuitous political reference? http://en.wikipedia.org/wiki/Guerrilla_marketing
Re: [Vo]:Guerrilla (Gorilla) marketing
Yep Jones, I keep a copy of Don Quixote on my bookshelf. One must read Cervantes often, less I forget the joke. True, ole Don was portrayed as a simpleton that supposedly thought the world was run on the level. And yes!, he had this idea one could fight windmills or city hall, and yes, he was a comic-tragic personality.. BUT... beneath the surface of the story lurks another level of the human physce.. and beneath that level lurks the message. What's the message?? why, I thought you'd never ask!! 50% of nothing is nothing. Richard Cervantes may have left us some time ago, but what is that smell?

Re: [Vo]:HiPER Fusion
Between 35 and 40 years ago I did a term paper and oral presentation on hot fusion for a high school class in ... I forget which subject; not sure what grade it was, either. Certainly it was *at* *least* 35 years ago. Conclusions that I drew: -- Laser fusion would be possible, *but* the only lasers powerful enough at the time were neodymium glass lasers, and they had several problems: They were expensive, they were very inefficient, and the glass cracked after a relatively short working life. Consequently it was hard to see how the process could ever be made practical -- or even over-unity -- unless far, far better lasers were developed. -- Magnetic confinement fusion had proved much harder than anyone expected, due to the fact that super-hot plasma in a magnetic field acts like a very badly behaved fluid. It develops peculiar instabilities when it's hot and under pressure, which result in its wiggling out of confinement and touching the container walls, at which time it cools off instantly and that's the end of the reaction. It's kind of odd that almost four decades later, the same exact oral report could be given over again with almost no changes. Oh, there've been some improvements in laser technology; they've finally gotten better materials than neodymium glass, I think. But the basic problem -- too little beam power at too high cost and too low efficiency -- hasn't changed. And magnetic pinch, zeta pinch, stellerator, and so on designs have evolved into the Tokomak and variations, which can contain the plasma longer and and under more pressure -- but the fundamental problem, which is that magnetic bottles leak like Klein bottles, remains the same. When God builds a nuclear reactor he uses brute force. Humans are trying to use cleverness to get the same result with a lot less force, and it does seem rather like the basic problems are kind of fundamental...
Re: [Vo]:GM and EPA dispute Volt's MPG rating
In reply to Jed Rothwell's message of Wed, 08 Oct 2008 10:05:44 -0400: Hi, [snip] Robin van Spaandonk wrote: Clearly the EPA needs a new category for PLUG-IN hybrids, as opposed to ordinary hybrids. (The volt is NOT an electric car. It IS a plug-in hybrid). Yes. The thing is, there are gradations with hybrid technology. A car can be mostly an ICE (weak hybrid) or a balance (like the Prius) or it can be mainly an electric car (the Volt). The difference lies in the plug. If the car comes equipped with one, then it is clearly designed to be driven for extended distances on electric power alone (otherwise there is no point in supplying a recharging capability), and should not be subject to the same rules that apply to ordinary hybrids or gas vehicles. What the new rules should be, is an open question. So it is hard to categorize. You have to have some sympathy for the EPA on this. It is difficult to measure efficiency when you have to take into account inputs from electric power which can be generated with fossil fuel, nuclear power, wind, etc. Conventional cars are simple. Their efficiency and carbon footprint does not change when you refuel them in the middle of the night. The EPA has to adapt to the fact that it is not just going to be difficult to measure efficiency, it's going to be absolutely impossible. This is because every driver will travel different paths, and hence achieve different efficiencies, and also because of the fuel mix you mention. At most, the EPA can measure maximum and minimum efficiencies. However the advertising used by the manufacturers, and the experiences of the general public, can provide a hint as to what direction the new standards should take. E.g. I would think that the maximum distance that can be traveled in pure electric mode would be a useful criterion (which is already in use by the manufacturers and public). There have been proposals to allow hybrid cars to use the HOV lanes on highways. The trouble is that some weak hybrid cars are less efficient than ordinary cars, and an ordinary compact car that gets 35 miles per gallon carrying two people equals 75 mpg per passenger, which is better than a Prius. So this policy makes no sense. Perhaps they should open up HOV lanes to any car that gets 35 mpg or better, but it would be awfully difficult to identify them. I don't think a change to the HOV rules is necessary. Soon, many if not most vehicles will be plug-ins anyway, without any encouragement from government. The public can't wait to get their hands on them. Ultimately, what we need is a RFID identification and onboard computer on every car that automatically tallies and pays a toll for every mile driven on every road, depending on the gas mileage of the car, the time of day (with a premium charge at rush hour) and other factors. It would be intrusive, but it is the only fair way to pay for roads and reduce congestion. This will especially be needed if cold fusion is commercialized and gasoline taxes go away. See chapter 17 of my book. [snip] There is a simpler and less intrusive solution. Put a tax on tyres iso gasoline. Has the added advantage that careful drivers pay less tax. :) Toll roads help too. Of course, that wouldn't be enough, so the rest should be taken from consolidated revenue. Perhaps needless to say, this shouldn't be done until gasoline has gone the way of the Dodo.
