Mr Higgins is correct, it is scary what people will believe, even when something obvious is mentioned, like "conservation of energy".

Maybe, but where did the energy to free the chlorine come from? None of the combinations will release more than it took to free the elements from the compounds. I'd love to find out that I'm wrong, though. Wow, go away for a few days, and everyone is peein' in the pool! Di-Hydrogen Oxide is, as the name suggests, "already burnt". Or call it oxidized if you wish. The gullible know just enough to make an almost intelligent assumption - "Well Hydrogen is really flammable - Look at what happened to the Hindenburg! - disregarding that what they were watching burn was the incredibly flammable fabric coating, and because there is a good chance that the red insensitive film emulsions of the day would have a hard time seeing that hydrogen flame. But I digress. And Oxygen! That stuff is pretty good at making things burn! By golly, release those, and we have a world full of fuel for the family Escalade! Fuel will be too cheap to meter! But sorry sports fans, it did indeed oxidize, and a long time ago at that. So well burnt that it does a fair job of putting out most fires. Electrolyzing is after a fashion un-oxidizing it. That will almost certainly take more energy than whatever is produced. I have to say almost certainly because there is always the chance that a singularity will pop up here in the newsgroup and start spitting out refrigerators. But almost certainly not... Pure water is hard to electrolyze, and adding chemicals like salt to enhance the conductivity produces some nasty additional chemistry. Like that Cl. Wonder what that will make with the H?

In all the debate about what type of flame is burning, how much and what
type of power is being generated and how; the main point seems to have been lost. This guy is primarily claiming that he has developed a cure for cancer and not a limitless source of power - that's just an incidental by product. He has a lot of expensive looking equipment that can generate focused microwave radiation. It can produce enough power to dissassociate water molecules and/or create plasma flames. He also appears to have access to some buckminster fullerine C60/C70 particles judging by the colour of the solution in one of the test tubes. His (rather simplistic) hypothesis is that cancer cells are better supplied with blood than other cells in the body (which is generally true). By injecting metallic nano particles into the bloodstream, these particles will be carried preferentially to cancer sites (which again is generally true for the first few minutes after injection). His machine is then used to zap the patient and all the nano particles will heat up to 65 degrees centigrade and destroy the cancers (wishful thinking but true if it could be achieved) leaving the rest of the body unharmed. The principles are basically correct but the nano particles will not differentially seek out tumour sites in the way he hopes. The time variables and circulation patterns in different individuals are too great. What happens if the cancer is interfering with general circulation as it often does? Current research is aimed at finding compounds which will bind to specific tumour sites using specifically engineered proteins. Once this has been achieved, then metallic or other types of particles can be added to the protiens and used to target tumours. Then any specifically tuned radiation source could be used to heat the particles adhering to the tumours to kill them - or to release a poisonous compound designed to kill only the tumour cells. Research in this area has been going on for years and is starting to signs of considerable success. One problem is that if you suddenly succeed in wiping out all tumour cells in the body in one hit, what will happen to all the waste products created by the dead cells? The kidneys and liver will be overwhelmed and the patient will expire from toxic shock. This is just one step on the way to developing a cure and there will probably never be a cure that involves just being zapped with microwave radiation for a couple of minutes, The cancer has all gone, but the patient dies from the side effects of the cure. The best option is to kill the tumours a bit at a time and allow the patient to recover between treatments. Either that, or a new 'cure' will be needed to flush out all the poisonous compounds as a result of the dead tumour cells rotting away inside the body. As for sticking your hand in the path of a microwave beam, a one kilowatt CW transmission only causes a sensation of skin warmth for a few seconds exposure. Obviously other damage occurs at deeper levels in the body, where there are fewer pain sensor cells. The demonstration looks spectacular, and makes for a good news story but doesn't actually prove anything. The idea of one man working alone in a home laboratory inventing what multi-national research corporations with billion dollar budgets cannot is a very appealing one. Unfortunately history shows that it is the well financed, research labs that tend to succeed, not the one man band. Edison, Marconi, and Bill Gates for example, were all pretty wealthy, connected and had a good deal of support behind them before they succeeded in dominating the world with their inventions. Even Tesla was doing alright for a while, until Edison 'proved' that his way of doing things was better - the advantage of having better financial support and that it was more practical and cheaper to install a proven technology using copper wire. Copper wire had been used for low power signalling applications for a long time before it was used to distribute power. If there is anything of scientific merit at all in this 'invention', one of the multi-nationals will undoubtably have already been developing it and not revealed the details due to patent law requirements. Hopefully I am wrong and we will all see a universal cure for cancer rolled out to hospitals in a couple of years time. Once cured, we will then be able to go out and kill ourselves by driving too fast in our hydrogen powered emission free cars. Scientific progress works by building step by step on the work of others that have gone before. That's the way the world has worked for at least the last 6,000 years since the Babylonians, Greeks and early Arabic civilisations developed the scientific method. Individuals may have a Eureka moment, but it takes time for new theories to become accepted and its the people with financial muscle that ultimately get to exploit new innovations and make even more money. Finally, if you look at the history on invention, you will find many instances of new technology being invented almost simultaneously around the world throughout the centuries. This points to a perhaps deeper underlying principle that technology has to reach a certain stage before the next step can be achieved. It may well be that a multiband 99% efficient HF antenna can be built into the form of a six inch cube. However, that will probably need room temperature superconductors to become available. Once that happens, people will be 'inventing' these antennas all over the world. Rant mode off Mike G0ULI |

It seems you have read something into my comments that I did not put there. Your comment on energy states was offered in the context of "true, but one must also consider..." Where's the information that supports the implications of that "but?" Hydrogen as a combustable fuel is generally considered to have a net loss from an energy budget standpoint.

Now days much of the population has computers, but only a very small percentage is truly computer literate. As a grad assistant I taught the intro to computer science. The level of knowledge in those students was scary and that was at the university level. Many a multimillionaire owes his fortune to what others have considered garbage where others have deemed themselves as educated enough to detrmine what is garbage and what is treasure. However they were working from sound scientific or business principles, not something that violates the laws of physics. Look at the good side of this picture instead of piling on ridicule. Here we have is a human being who is fighting for something new and beneficial to all with all the energy and education that he has within him so that he can hold on to life. The life he has is enjoyable because he believes he is on the brink of success, where his life is still usefull instead of lying on a hospital bed. For a human to be brought from sadness into happiness is a wonderfull thing that typifies the human race and encouragement is what a human needs instead of derision to enjoy a life that has been given him. It is not sad to see a life ending in enjoyment but it is sad to pile on derision on how a human carries on the fight for life even in the light of a meagre education. What is more sad it when some one is encouraged to go on a "fool's errand" and gives the "man on the street" false hope, so in the end instead of one disappointed person, thousands have their false hopes dashed. Realistically tinkerers, engineers, and scientists alike all know their individual searches may end up in failure and accept that as a fact of life. If he was my grandpa I would encourage him until the end and be very proud of him and not use my education to discourage him. Actually the news media should use that story for those people who are interested in what is good in life as well as those Although this approach sounds charitable to create false hopes in the person doing the research and those who believe in it is very cruel. To encourage research, experimentation, and to push the envelope is good, but to give false hope even in the name of charity is not. I would far rather work under the sense of what I do has he odds against it rather than a false grandiose hope that would or could leave me and worse yet those who believed in me with dashed hopes. To point out the failings in a piece of research is not derision, as long as it is done in a respectful manner. It is in fact an attempt to help the individual rather than to encourage them to pursue "junk science". Mankind has been looking for perpetual motion since we had enough brain power to envision such a fallacy. Most any engineer can show the weakness behind this idea and prove them. Yet there are those who believe we can violate the laws of physics/nature with impunity and there are those who encourage it. There are many things far more practical and rewarding for the individual and society as a whole that are much more likely to succeed. Those are the things we should encourage. who only have derision for the efforts of others. Regards Art |

Lots of power and little Hydrogen. Then you have the efficiency of the RF generator which if efficient may develop about 75% of the input power as RF. Just a plain old DC current is probably much more efficient. Of course with the DC current it's easy to seperate the H2 and O2 which is a necessity. Using microwaves they come off mixed which is not a good thing. Looks spectacular but not very useful. For many years I worked in the semiconductor industry (over 26). I believe NASA was the only larger user of liquid H2 than us. We had a large tank farm of liquid H2 and the stuff was not the easiest stuff to handle. It requires very low temperatures to maintain a liquid state which means a *lot* of evaporation. You aren't going to make much difference even increasing pressures. On top of that you get liquid Oxygen condensing on pipe fittings and running off. Good combination, liquid H2 AND O2.

H2 by itself does rise rapidly, but it is so active physically it mixes with the air and the rise is not nearly as fast although it does dissipate relatively quick. OTOH you have to get rid of almost all of it before it is no longer dangerous from an explosive point. The lower explosive limit (LEL) is only 4% while the Upper Explosive Limit (UEL) is 96% meaning if it's present it's probably within the explosive range. Another problem with H2 is it doesn't take much flow to create a substantial electrostatic charge resulting in a spark and ignition. In both cases I'm familiar that was the cause of the explosion. In the one case a worker was standing within a couple of feet of the large container which was at low pressure. Just a couple inches of water pressure above atmosphere. He was looking at it when it blew. You could see the imprint of his goggles and shape of his face in the Aluminum. He did survive, but it was a couple of days before he could hear again. Pretty amazing as it basically blew him through the equivalent of a wall. In the other case it blew a worker through the "blow out panels" in a wall plus about 30 to 50 feet. He was back to work the next day. In both cases there was enough air movement that the bulk of the force was within a few feet of the floor. snip |

Hydrogen is probably here to stay, it is only how we will produce it that is in question. Pollution alone is enough to make us take its' path. While "evil" smoking is in decline and been so for some time, lung cancer continues to rise at an alarming rate. A search of the web will convince you that all respiratory diseases are on the rise. While they have done wonderful things to make exhaust odorless and invisible, we are still breathing great quantities of it 24 hours a day, 7 days a week, 4 weeks a month, 12 months a year, for our whole lives, with china coming on line we are about to see real pollution rolling in on our west coast, we then add our pollution to it and by the time it hits the east coast--I pity the poor air breathers there ... Monday, as you cruise to work, contemplate the river of vehicle exhaust you are submerged in, the tens of thousands/hundreds-of-thousands/millions/tens-of-millions/etc. of cubic feet of toxic exhaust which is being spewed out before your path, for miles and miles ahead ... you will begin to grasp the need and importance of hydrogen ...

I doubt any one is arguing that Hydrogen is generated, the problem is it is a very inefficient process both from how much hydrogen is generated compared to how much RF it takes to generate that Hydrogen. ... The most efficient solar cells are about 20% efficient, efficiency is in the eye of the beholder. With an, almost, never ending supply of sunlight--they suddenly begin to make sense ... a two fold increase in efficiency would change everything, yet still be only 40% efficient. The replacement of batteries with storage tanks is an economic advantage of hydrogen over electric ... and an IMPORTANT one, well, until better and more efficient batteries come along. ... ... Using microwaves they come off mixed which is not a good thing. Looks spectacular but not very useful. They come off in exactly the necessary ratio to burn at 100% efficiency. Unfortunately they are mixed in that ratio and there is no safe way to store much comprised of that ratio. They need to be separated to be stored safely. Hydrogen can be stored in a metal sponge (Metal Hydride) which is quite efficient. Expensive, but efficient. Now, a way make lemonade from that "lemon" is only necessary ... ... Trucking H2 is expensive and piping it much of any distance as a liquid is out of the question. Yeah, I'd pipe it as a gas ... allowing its' own pressure to "pump" it. The problem with piping it as a gas is transferring sufficient volume and then it'd have to be liquefied at the receiving end. Another problem is keeping it liquid. You really can't carry a lot as a gas under pressure and it takes a lot to develop much energy/power as the stuff is so low in BTU content. Taken out of context it is true that a Hydrogen spill dissipates much more quickly that a gasoline spill, BUT while it is dissipating it is far more explosive. OTOH a given volume of H2 has far less energy/BTU than gas. Put in perspetive both dynamite and TNT also have less energy per unit volume than does gas. The problem is the speed of the combustion front. In the end it's not quite true that a liquid H2 spill is safer than a gas spill. Depending on the speed of release/"moment of ignition", the bulk of the hydrogen burn/explosion is going to be well above your head ... hydrogen I've been around a couple of H2/air explosions. H2 by itself does rise rapidly, but it is so active physically it mixes with the air and the rise is not nearly as fast although it does dissipate relatively quick. OTOH you have to get rid of almost all of it before it is no longer dangerous from an explosive point. The lower explosive limit (LEL) is only 4% while the Upper Explosive Limit (UEL) is 96% meaning if it's present it's probably within the explosive range. Another problem with H2 is it doesn't take much flow to create a substantial electrostatic charge resulting in a spark and ignition. In both cases I'm familiar that was the cause of the explosion. In the one case a worker was standing within a couple of feet of the large container which was at low pressure. Just a couple inches of water pressure above atmosphere. He was looking at it when it blew. You could see the imprint of his goggles and shape of his face in the Aluminum. He did survive, but it was a couple of days before he could hear again. Pretty amazing as it basically blew him through the equivalent of a wall. In the other case it blew a worker through the "blow out panels" in a wall plus about 30 to 50 feet. He was back to work the next day. In both cases there was enough air movement that the bulk of the force was within a few feet of the floor. snip When I was a teenager a truck caarying H2 came into town and the driver decided to eat at a local restaraunt. Unknown to him his tank had a leak. I saw the heat disortion above the flame and called the fire department. When they got there they started chewing my butt because it want on fire, then one of the firemen walked into the flame. Jimmie |

You need to go back to High School Chemistry Class and relearn all you missed about Hydrogen Oxygen Bonding, and the Energy required to break those specific Chemical Bonds. It isn't going to happen in a simple Plastic Membrane, especially without some form of external energy input. Where do you guys come up with this stuff??? Idiots R Us??? |

You need to learn how to focus and digest written material in a sane, logical and meaningful way. Hydrogen gas can be separated from oxygen gas with the plastic membrane, as stated. What? Did you sudden get thirsty and focus on water, idiot! JS |

Idiots R Us??? actually with what you quoted it is perfectly correct... in that quote he isn't saying he's breaking down water into hydrogen and oxygen, just separating the atoms. a gaseous mixture of hydrogen and oxygen could be separated this way. |

Just your typical small town volunteer fire department of the 60s. 40s vintage fire truck, no special clothing or protective equipment. Siren goes off, drive to the one red light in town and wait to see which way the firetruck goes. Jimmie |
