Typically you will get about 30% - 40% from an internal combustion engine.

      There are other types, as described in the very recent book _Megawatts and Megatons: A Turning Point in the Nuclear Age?_ (pp. 254-255):


      Proposals for the use of nuclear bursts to produce electricity were made during the decades when the United States had a substantial program in peaceful nuclear expolsions, which preceded but was smaller than the Soviet effort. In particular, one plan of Los Alamos, Project Pacer, called for the production of electrical power by the explosion of thermonuclear explosives in underground cavities filled with high-pressure steam. Each day, a 60-kiloton nuclear explosive would be detonated in a cavity to keep the steam hot, while a relatively conventional steam-turbine power plant would draw on the steam reservoir to produce electrical energy. Nuclear heat from the explosion would simply replace a day's nuclear heat from a reactor.

      In 1975, one of the authors (Garwin) worked on an advisory group to the U.S. government studying the whole field of peaceful nuclear explosions, and Pacer in particular. Although it had been claimed that Pacer was a cheaper road to nuclear power than the reactors that were mature at the time, side-by-side comparison with a normal nuclear power plant showed otherwise. In addition, the scale of the nuclear explosive manufacturing and transport program was almost unfathomable. Each of the 60-kiloton explosives would have had an explosive yield some 4 times that of the bombs that devastated Hiroshima Nagasaki. For each of the almost one hundred nuclear power plants operating now in the United States, 365 such explosions per year would be required, -- 36,500 per year in total. It is unreasonable to think that humanity might consider technology of this kind, while it is still searching for satisfactory methods for properly managing nuclear power plant waste and trying to reduce the number of nuclear explosives.

      Major projects continue to be set forth -- most recently by the Russian nuclear weapons laboratories. In an audacious scheme, scientists have analyzed an enormous steel pressure vessel using a year's output of all of Russian steel mills for the container, to be equipped with multiple fountains of liquid sodium inside, for the purpose of shielding the steel container from the force and radiation of the 20- or 50-kiloton thermonuclear bursts. The possible attraction of such explosives in peaceful use lies in part in the fact that the only relatively small quantities of fission products and plutonium are produced. For the Russian 120-kiloton explosive used in rock crushing, it amounts to a mere 300 tons of high-explosive equivalent from fission. This results in a factor of 400 less fission products than in a nuclear reactor; the rest of the yield came from fusion of deuterium. This approach would thus compete with approaches for extending uranium fuel supplies -- e.g., a breeder reactor -- or obtaining uranium from seawater.

      In the mid-1990s, it was the turn of the Chinese to consider the possibility of producing electricity by means of nuclear explosions. They suggested that with underground explosions within the yield range of typical thermonuclear weapons (10 to 100 kilotons), energy could be produced from uranium-238, and thorium-232 could be burned, multiplying the accessible energy of any particular uranium resource by a factor of 100 or so with respect to what can be obtained with ordinary reactors that burn only the 0.71% of natural uranium that is uranium-235. In these underground explosions, thermonuclear reactions could provide 90%, or even 99%, of the nuclear energy released. According to the authors of the project, there would remain only a few modest technological problems to solve. This was not, of course, a brand new idea, but it was being taken seriously for the first time in China.

Of course, they run down pretty fast when you use them this way, but batteries are definitely not the limiting factor in an acceleration test. The reasons electric cars might be slow:

      1) The batteries are heavy, so the electric car is considerably heavier than the same model with gasoline power.

      2) To get more range out of the batteries, the designers may have limited the motor power.

      3) If you do run a battery-powered car at high speed and accelerations, you won't get far.

      Fuel cells could help on all three points, not because they put out more current, but because they allow you to store more energy in less mass.

      I am no expert, but I would expect short-term fuel cell output to be limited by the rate at which the fuel and air can diffuse to the electrodes and react. This is going to be a lower rate than you get from batteries where the lead and acid are already at the electrodes. Sustained output of both fuel cells and batteries may be limited by heat -- when you draw too much current, you increase the losses in the cells, and lost energy becomes heat, which must be removed or eventually the cells will self-destruct.

      This is incorrect, while hydrogen fuel cells can in theory develop more Watt/hr per kg than batteries none of the units produced have been able to do so. Most fuel cell powered vehicles will need battery or flywheel systems to store energy for peak loads.

Most average cars Electric cars require 600amps of current. No hydrogen fuel cell on the planet puts out those current levels and can still fit in a car. For those current levels only batteries can deliver energy quickly enough.

      Hydrogen's only advantage over battery power is you can refuel quicker.. it might only take 10 minutes to pump enough hydrogen into the car for another 100 miles of driving. Batteries might take 15 minutes to several hours (charge rates are mostly limited on how much electricity is available, most homes do not have sufficent power available to quick charge an EV).

As it uses the H2 to drive, the car uses solar power to break up the waste water and fills up the H2 tank. It's not quite a perfect system, since you may do a lot of night driving or park in a garage and thus end up with all water and no hydrogen, in which case you'd have to tank up with H2. The system would also leak a small amount of water, which I supose could be replaced from capturing rainfall. Depeding on the efficiency of the electrolysis and solar cells, it becomes something between a gas mileage enhancer and a true self-contained car.

It takes a lot of energy to split H20 into H2 and O2 (or rather 2H2 and 02) and the potential for heat loss during this process is high, as anyone who has ever studied thermodynamics will know. You put energy into the system to split the water molecule, probably on a metallic catalyst of some kind to reduce the energy requirements, but only a certain percentage of that energy is used for the hydrolysis, most of the rest is released as heat.

Build a prototype hybrid hydrogen/hydraulic engine (so that a little hydrogen produces a lot of torque) and then sell it to trucking as a way to meet and beat the US emissions requirements.

      My scheme actually also involves closing the system (cooling and re-cracking the exhaust) and introducing electricity into the system partially by means of solar. Other possibilities (for the nighttime trucker) include flywheels that can be charged at stations and during the journey, and for trains, just bearing the burden on the same thing that drives electric engines now.

      The hydrogen/hydraulic engine is supposedly a very efficient way of producing a lot of torque for a little energy, which makes it ideal for hauling heavy loads. However, I'm going to have to check my facts. Still, if so, this would be a great way to start the little industry that could.

How about reducing the tuna kill every year to a number which will guarantee that they will not go extinct. I am talking about a sustainable yield and not one pound more.

      "Spoken like a true greenie. Yes, let's kill and hurt people to protect plants and animals! (All three of which are renewable resources, but I'll let you decide which one is more valuable.) "

      yes plants are animals are theoretically renewable but unfortunately they are being consumed faster then they are being renewed. The forests, topsoil, coral, plankton, etc are being consumed much faster then they are being replenished. Sorry the word renewable only applies in the abstract sense not in the real world.

      First of all I don't advocate killing people. Violence must be directed at economic targets to make the cost of extracting resources higher. Killing a logger or a fisherman accomplishes nothing. To their employees these people are "renewable resources" and will simply be replaced by the next guy in the street. No CEO will ever weep the death of a logger and rethink his plans to log. What will make him rethink it is the escaling cost of logging due to sabotaging to expensive logging equipment, increased insurance etc. Money is the only thing he cares about and you will only get his attention by raising his costs. BTW although this is violence it's also self defense. Much like we kill people in afghanistan who had absolutely nothing to do with sept 11.

      As for you "worth" argument. I can certainly make an argument that some animals are worth much more then humans. It's a matter of supply and demand. If there are only 300 canadian lynx left in the world then one canadian lynx is certainly worth many many humans. There are 5 billion humans in the world. Human life is so cheap that humans themselves kill each other at the slightest provocation. 5000 people killed in NY, a million killed in Iraq, thousands killed in palestine, tens of thousands in africa. There are so many humans tens of thousands starve to death every day.

      Even you would probably morn the extinction of the canadian lynx more then you would morn ten thousand dead afghans.

Nevertheless, even after the nuclear power plant was vindicated - the media failed to report that the solvents killed the people, not the power plant.

It's another way of saying "less pollution is an absolute good which justifies any cost to consumers whatsoever". With which I assert that most consumers do not agree.

      Back to the "tax" analogy: even when you agree with a tax, it is reasonable to say "___ raised it too much, let's lower it back to a previous level". I feel that way about income taxes - the Clinton administration raised them too high - even though I agree that it is reasonable, in principle, for the Federal government to collect income taxes. I haven't studied the issue with EPA regulations, but it wouldn't surprise me one bit if that same administration went overboard there as well.

    Fission is clean power to public relations people and a government that wants a good source of radioactive material for weapons, but to engineers it is very dirty power that needs to be very carefully contained in case it gets out and kills everything near the powerplant.

All of those rare earths and hi-tech materials are not cheap - and everything used in the steam cycle is going to be radioactive enough to cause storage problems for more than a lifetime.

      3 points.

      First, engineers do not regard nuclear power as a dirty source of energy that must be contained, lest it kill everyone. I live in a small city in Arkansas (Russellville, population ~25,000) that is the site of a large nuclear power plant. I know many engineers who work at the plant and a few people involved with the construction and design of the plant (such as my father, who did the environmental impact work on the 'steam cycle,' more on that later). Those engineers regard nuclear power as an extremely safe, potentially cheap form of power. The total number of American deaths from nuclear power is incredibly small compared to that of coal/oil/natural gas and their related activities (such as coal mining).

      Second, nuclear power plants can be built very cheaply. The cost of construction is only about a third of the cost of building a plant (a large plant would, if built today, cost in the neighborhood of 300 million dollars, depending on location (i.e., availability of natural cooling sources like lakes and rivers) and output). Whenever a nuclear power plant is built, the design documents, environmental impact studies, evacuation plans, etc, must all be submitted to the Nuclear Regulatory Commission as though no nuclear plants had ever been built before. Read that again. The majority of the cost of building a nuclear power plant in the United States is red tape. Nuclear power is cheap. Nuclear power plants can be cheap. In France, most of the power plants follow the same, well-tested design.

      Third, the water used in the steam cycle is extremely clean. During construction of the plant, the chemists (such as my father) had a valve system in place such that they could take samples of the water at every stage in the cycle. After testing the water, the chemists would often wet their whistles with the excess. The water was just plain, distilled water. The only thing that happens to it is being heated and cooled over and over again. The steam (water vapor, technically) put off by cooling towers is likewise incredibly pure. In the Russellville case, the only thing in the water vapor other than H20 is a small amount of (non-radioactive) Xenon, which, for those of you who slept through chemistry, is inert. Perhaps you meant the coolant itself? Well, the coolant is heavily laced with Boron (in the form of Borax soap, actually), which is a neutron absorber. It's only a 'coolant' in the sense that it absorbs neutrons. Even if the Boron did become radioactive (and I'm fairly certain it doesn't), that water isn't part of the steam cycle and the Boron can be removed from the water anyway.

      The majority of your fears (and the public's fears) about nuclear power are unfounded.

      In comparison to what other forms of power? The exotic materials required push up the constuction cost, which is offset by the lower fuel costs, but the extremely high cost of decommissioning a plant adds in a major cost as well to produce something that is not very cost effective in terms of producing power. The decommisioning cost will most likely go down and perhaps someone will be funded again to solve the waste storage problem, but currently those problems push nuclear power generation into the catagory of a good idea that doesn't quite work. Nuclear power stations are only built by nations that want to be self-sufficent and don't have other resources, or nations that want to build atomic weapons. Britain cancelled the construction of a nuclear power plant a few years ago on economic grounds, you'll find something article about it in a 1996 "New Scientist" magazine (I wish they had put stuff on the web back then).

      Nuclear power plants can be cheap
      Example please. The only cost breakdown I've seen was for the unbuilt British plant listed in a "New Scientist" article - and that one was very expensive in comparison to a coal fired plant. They didn't really need it since they left the cold war early.

      An accident in a coal fired power station or oil refinery can kill a few people, but an accident in a nuclear power plant makes the entire continent worry - just ask a few europeans how "clean" they think nuclear power is.

I've read about the subject (a long time ago now) and talked to a couple of engineers from nuclear power stations - one that I was working with and another that I was teaching (about ceramics - so not much to with the subject). I'm not in opposition to nuclear reactors, since we need a source of radioactive materials for a variety of reasons (medical etc), and I've used an Iridium isotope to examine weld joints at an oil refinery, and thick welded test plates. I've talked to one of the people that worked on the "synrock" project for containing nuclear waste (it probably works, but we'll never know). I've also worked in coal fired power stations, alongside people that work in the research facility attached to my nations small reactor. What I do think is that using very large quantities of radioactive material is a dangerous and expensive exercise. Ask the Swedes and Fins how much they are spending to prop up the reactors in the old USSR - it's bound to be on public record somewhere.

      Grob, the three points you make are interesting, but incomplete.

      First, while you could find any number of engineers (or plumbers, politicians, math teachers, or any one else at all) to think of nuclear as a clean source of energy, a lot of learned folks know otherwise. The US hasn't actually mined for nuclear products in decades. We are using supplies gleaned from the past, or mined elsewhere. The legacy of this effort is comletely missing from the innocuous consequences you put on the table. It has been, frankly, devastating compared to coal or gas- cancer bills the government is even staggering to pay off, superfund sites, radioactive areas cordoned off, radioactive atmospheric and airborne particulate problems, etc. The future of uranium mining hasn't changed a bit since then- we haven't had to (yet). In addition, disposal is the other half of the equation that is completely missing from the debate. We cannot convince a body of knowledgeable people that we have an acceptable disposal solution. We store the waste in our existing (numerous) facilites, and they are at or approaching capacity in MOST cases. The costs for the "final solution" never have been ammortized into the costs of nuclear energy we see in the press. Why? The costs are currently astronomically problematic, both in safety and dollars.

      Your second point is simply wrong. While there are profitable nuclear plants out there, most plants have never produced more energy than was required to build and fuel them. In fact, the most efficient designs on the table in the US require upwards of 12 years to break even. Most current projects have been decommissioned before this time. France's programs tout profitability ONLY when subsidies are included, their uniquely high coal or alternative source costs are accounted for, and their convenient waste disposal program (yes, the Pacific Ocean, only recently preferred over their own Atlantic coastlines) is ignored.

      Your third point is misleading. The water cycles (or whatever transfer cycles are uses) are indeed very clean. This is a bit like saying that the Ford Excursion is a clean vehicle because it has that new car smell. It's a red herring. The fuelling process is polluting. The mining for the resource is polluting. Disposal is polluting and uncertain.

      Until we address these problems, nuclear power will remain an albatross without the supply of mental hygiene the nuclear power industry seeks to promote.

    Hydrogen is a clean fuel, in that it can be burned without harmful emissions. Because water is plentiful, hydrogen is also a sort of a battery. Electrical current can be used to separate it from water molecules, and some of this energy can be recovered in fuel cells.

    Hydrogen extracted from fossil fuels necessarily produces less energy than the raw fuels themselves. Hydrogen produced from water by electrolysis is an energy sink.

    Hydrogen may be extracted from water by using solar energy. That is solar energy, not hydrogen energy.

    Whether hydrogen is a suitable fuel for vehicles depends on whether the energy costs are worth the emissions benefits. If so, this will make energy more scarce, because of the inefficiencies of converting energy in some other form into the energy of electrolysis.

    Whether electrolysis of water is the right method for storage of solar energy depends on the comparative costs, risks and benefits of alternative storage technologies.

    In neither case is hydrogen competing with fossil fuels as an energy source. It is competing with fossil fuels and batteries and flywheels and passive heating media as an energu storage system in both cases.

    There are no significant pools of free hydrogen on the planet that can be used as an energy source.

    Hydrogen is an energy storage strategy and not an energy supply strategy. It may have its uses as the former. Proposing it as a replacement for fossil or nuclear energy is complete nonsense.

    All the above should be fully understood by anyone trying to venture an opinion on this subject.

      Dear
      (correspondent):
      To
      give you an update:
      We
      already had the first action with the U.S. patent office on our first
      patent for the Motionless Electromagnetic Generator.
      Many of our claims were recognized.
      We then entered a strong refutation of the stated reasons for declining the other claims. That refutation has been upheld, and now
      we have received notification from the patent office that our first
      MEG patent will be issued with all 30 claims recognized.
      In addition, a second patent application has been filed, on
      other aspects of the MEG device, which in the latest embodiment
      variation is called the TGEN (transformer-generator).
      Also,
      we have now secured an agreement with the National Materials Science Laboratory of the National Academy of Science in a friendly foreign
      country, to do the necessary advanced research to finish the MEG for
      scale-up and commercial production. The first commercial units should
      be rolling off the production lines in about one year, and we expect
      them to be closed-loop self-powering systems of about 2.5 KW output,
      but modular. So -- say --
      four of them can be arrayed with a synchronization unit (under
      development simultaneously) to produce a 10 KW output.
      Two
      papers on the MEG have been published in Foundations of Physics
      Letter, after -- to put it mildly -- vigorous refereeing.
      A high-ranking board member of the corporation owning that
      series of journals personally objected to these papers on extracting
      EM energy from the vacuum as "perpetual motion" nonsense.
      I wrote a very strong rebuttal, also containing my solution to
      the long-vexing source charge problem and its agreement with quantum
      field theory and particle physics, so hung him on his own petard
      unless he could explain why and how every charge and dipole in the
      universe is already known to be continuously outpouring EM energy in
      all directions at the speed of light, and has been doing so for some
      14 billion years. Based
      on that paper, the referees of the second paper rejected the formal
      protest by the member of the board, and recommended publication of the
      paper. Whereupon the
      journal published it.
      A
      marvelous and very rigorous review by Myron W. Evans, who has some 600 papers in the hard literature, will be in the forthcoming second
      edition of Modern Nonlinear Optics, Wiley, 2001.
      I also have a paper on the MEG in one of the three volumes, and
      a second paper on the principles for extracting EM energy from the
      vacuum.
      As
      stated, in 2000 after about three years work I also solved what has
      been called the most difficult problem in electrodynamics: the
      association of the fields and potentials with their source charge.
      This year I found very strong support for my solution in Mandl
      and Shaw, Quantum Field Theory, Chapter five. The
      solution is also strongly supported by the known broken symmetry of opposite charges -- such as the two ends of a dipole -- in particle
      physics. Lee and Yang
      received the Nobel Prize in 1957 for the prediction of broken symmetry, which was experimentally proven by Wu et al. in early 1957.
      So revolutionary was broken equilibrium to all of physics, that
      the Nobel Prize Committee awarded the Nobel Prize to Lee and Yang the
      same year, in Dec. 1957! So
      it appears the solution is rock solid and will hold up.
      It also is what really allows EM energy to be easily extracted
      from the active vacuum.
      Further,
      at least three other inventors have working overunity systems as well.
      Recently one of these inventors -- a close colleague of many
      years -- and I solved another formidable problem: the problem of
      close-looping an overunity electrical power system.
      Contrary to prevailing opinion, this is not a trivial task at
      all, but is a most formidable one involving some very novel physics
      indeed. We have now filed
      a patent application upon that process -- for stabilizing, locking,
      and close-looping an overunity system into stable disequilibrium COP>1.0 operation.
      I
      also will have a book published by World Scientific, early 2002,
      giving the complete concepts and principles of overunity electrical
      power systems freely extracting their energy from the vacuum.
      With
      Evans' magnificent paper, we shall have put EM energy from the vacuum very solidly into the scientific literature.
      The
      energy crisis can be completely solved and self-powering (powered by
      the vacuum) generators and power systems quickly developed, whenever
      the scientific community will allow the work to be funded.
      It can also be solved in a way that will make the environmental
      community very happy, because nuclear power plants, burning of
      hydrocarbons in power plants, a great variety of hydrocarbon-burning
      small engines, etc. can be replaced eventually by energy from the
      vacuum-powered systems. In
      one year or so, we ourselves will be introducing our first commercial
      power plant on the world market, as stated.
      For
      your personal information, there are several Japanese COP>1.0

      One -- the Kawai system, can be built directly according to the
      patent if one starts with a high efficiency Hitachi magnetic motor of
      0.7 or 0.8 efficiency. Kawai,
      his company, and his system were taken over in 1996 by the Yakuza,
      right here in Huntsville Alabama, in my physical presence, and in the
      presence of the members of my Board of Directors.
      The
      broken symmetry of opposite charges -- such as on the ends of a source dipole, e.g., -- has been well-known in particle physics for nearly a
      half-century, as we stated. Simply
      see why Lee and Yang was awarded the Nobel Prize.
      Also, please check out what "broken symmetry" means
      in particle physics, and what it rigorously says about a dipole or
      dipolarity. It means that
      the dipole continuously absorbs unusable virtual photons from the
      seething vacuum (actually from the time domain; see my Giant
      Negentropy paper and Mandl and Shaw's book), transduces that energy
      into real observable energy, and re-emits it in all directions as
      real, observable energy in 3-space, flowing away in all directions
      continuously at the speed of light.
      A charge does the same thing (I simply treated the isolated
      observable charge with its concomitant clustering virtual charges as a
      set of composite dipoles). If
      you suddenly make a little dipole, and wait one year, the energy
      pouring out from that dipole will have changed the energy density of
      space in a sphere of one lightyear in radius.
      And it will still be pouring out the energy at the speed of
      light. The dipoles (and charges) in the original matter in the universe have been doing this
      for some 14 billion years. This
      is a true giant negentropy process, and hopefully it will initiate the
      engineering of negentropy instead of always negentropy, using stabilized disequilibrium COP>1.0 systems.
      Yet
      heartbreakingly, the vacuum interaction has not even been added into
      the 137-year-old classical EM model used to design and build our
      electrical power systems. Needless
      to say, neither is a broken symmetry in that interaction present in
      the model. Check this
      with a particle physicist skilled in broken symmetry, not with a
      classical electrodynamicist. Or
      read T.D. Lee's work, to establish the broken symmetry of two opposite
      charges (the dipole).
      Every
      charge and dipole in matter, has been pouring out energy from the vacuum (it actually comes from the time domain, and is time-energy
      converted to 3-spatial energy) for some 14 or so billion years.
      In
      other words, it is extraordinarily simple and trivial to provide "electromagnetic winds" of gushing EM energy from the
      vacuum, at will, anywhere in the universe.
      Just produce some charge or make a simple dipole, then leave it
      alone. It will pour out
      energy indefinitely and freely, so long as the charge or dipole
      exists.
      It
      follows that it is simply a technical problem to (1) intercept some of
      that freely outpouring energy flow once we make the dipole and pay for
      that, (2) dissipate the collected energy in a load to do useful work,
      and (3) do this without using half the collected energy to destroy the
      dipole and stop the free flow of energy from the vacuum.
      The
      present ubiquitous closed-current loop circuit, containing the source
      dipole itself, as used in electrical power engineering guarantees that
      half the EM energy collected in the external circuit is used to
      forcibly ram the spent electrons in the ground return line back
      through the back emf of the source dipole, knocking the charges apart
      and destroying the dipole. That
      process self-enforces the re-institution of the Lorentz symmetrical
      regauging condition, and the equilibrium condition.
      It absolutely guarantees that such a self-killing circuit
      cannot produce COP>1.0. That
      is not nature's prohibition nor the prohibition of physics and
      thermodynamics. It is
      merely the prohibition in the classical Lorentz-regauged model and the
      foolishness of the manner in which we build all our circuits to be
      equilibrium circuits vis a vis any exchange with the active vacuum.
      In
      other words, our engineers universally "put the windmill in a
      closed barn", so to speak, so that no
      net winds can get to it to turn it freely.
      In that case, it is not surprising that we ourselves have to
      input the energy to keep the darn thing turning and powering its load!
      Generators
      do not power their external circuits by any energy transduced from the
      shaft energy input. The
      mechanical shaft energy furnished to the generator is transduced into
      internal magnetic energy inside the generator, which in turn is
      totally dissipated on the generator's own internal charges to
      continuously reform the source dipole -- that the engineers
      diabolically design the circuit to destroy faster than the load can be
      powered. That is the
      reason and the only reason that present power systems are COP1.0.
      All the Poynting energy to power the external circuit -- and
      all the Heaviside nondiverged extra energy flow missing the circuit
      and wasted -- is extracted from the vacuum via the broken symmetry of
      the source dipole. Every
      system we ever built is vacuum-energy powered, not powered by
      hydrocarbon combustion, spillways on dams, windmills, solar cells,
      etc. No university in the
      Western world even teaches -- or knows -- what actually powers the
      electrical circuits they so confidently teach and utilize.
      Frankly,
      the environmentalists have been "had" now for quite some
      time. It would be most
      desirable if they actually did some foundations work and examination
      of electrodynamics, and particularly of the broken symmetry of the dipole. For that, they
      will have to go to the appropriate particle physicists, not the
      electrical engineers or the classical electrodynamicists.
      All
      the hydrocarbons ever burned, hydroturbine generators ever tapping
      water from a dam, windmills using the wind energy, and nuclear power
      plants heating water to make steam to run the steam turbine turning
      the generator, have accomplished one thing and one thing only: they
      have continuously restored the dipole that the diabolically designed
      external power line and closed current loop circuits continuously
      destroy faster than they power their loads.
      All that horrendous destruction and contamination of the
      biosphere has never added a single watt to the power line.
      It has only remade and remade and remade the needlessly-destroyed dipoles countless times.
      Needless
      to say, in my opinion that horrible mangling of the biosphere, destruction of species, pollution of the planet, and insane way of
      designing electrical power systems is -- to borrow a phrase from
      Nikola Tesla -- the most inexplicable aberration of the scientific
      mind ever recorded in history.
      It
      would be wonderful if the environmental community would in fact hire
      some leading particle physicists skilled in symmetry and broken
      symmetry, to prove to them the truth of the above statement.
      The shaft horsepower delivered to the shaft of the generator
      does not power the external power line.
      It only remakes the source dipole.
      The dipole, once made, freely extracts the energy from the vacuum and sends it out of the terminals and through space outside the conductors. A small
      component of that energy flow in space is diverted into the conductors
      to power the electrons. All
      the rest of the energy flow just misses the circuit entirely and is
      wasted. The existence of
      the Lorentz-discarded Heaviside nondiverged flow component is
      demonstrated decisively by the Bohren
      experiment.
      The
      Bohren experiment, e.g., simply resonates the intercepting charges instead of leaving them static. The
      definition of the "magnitude" (actually, the local point
      intensity and NOT the magnitude!) of a potential or field is defined purely as its reaction cross section presented in its interaction with
      an assumed unit point static charge at any point.
      By resonating the charge, it sweeps out a greater geometrical
      area, thus simply increasing the reaction cross section by the charge
      also penetrating outside the Poynting static reaction cross section
      and into the usually nondiverged Heaviside energy flow component.
      Thus the resonant charge simply intercepts some 18 times as much energy as is in the Poynting static cross section region of
      interception, by increasing the region of interception.
      So it intercepts more energy from that component not normally
      intercepted by a nonresonant charge, thereby proving that the extra
      (usually nondiverged) Heaviside component is physically present.

      The
      Bohren experiment outputs some 18 times as much energy as the experimenter inputs, since the input calculation ignores that
      "nondiverged" component discovered by Heaviside in the
      1880s, and discarded very shortly thereafter by Lorentz.
      Poynting never considered anything except the energy component
      that actually enters the circuit.
      Heaviside considered it all, both that component that is
      intercepted and the huge remaining component that lies outside the
      Poynting flow component. Simply

Obviously the main reason (and the one you'll hear from any government source) is that it's marijuana, and we all know how "bad" pot is for our health. I'm going to try really hard though to stay away from the legalization of marijuana, because it is a separate issue from industrial hemp.

    For starters, most people are unaware of that last statement, so I'll repeat it: INDUSTRIAL HEMP IS NOT MARIJUANA. It contains very low levels of THC, so low that you may as well smoke paper (except plain white paper is potentially toxic... we'll get to that later). Now, they are from the same family of plants, cannabis, but they are indeed different plants. Therefore, it is entirely possible to grow industrial hemp without producing marijuana. Most people (and senators/representatives) don't seem to realize that, or are concerned that THC-producing hemp could be grown in or around industrial hemp. The validity of that argument is up for grabs.

    But let's get to the point here, which is energy. What can hemp do? Here's a quick synopsis:

    ANYTHING MADE FROM WOOD OR OIL CAN BE MADE FROM HEMP

    Hemp biomass can be converted into gasoline more efficiently than fossil fuels (coal, oil) and without sulfur or acid rain as byproducts. Hemp fiberboard is stronger than wood, hemp houses are as strong as cement houses and better insulated. Plastic, rayon, and cellophane made from hemp are biodegradeable. Paper uses nearly half the world's timber. Hemp produces FOUR TIMES the amount of paper per acre as trees, and grows in all climates of the US. Hemp paper lasts about 1500 years. Cotton requires more pesticides than any other agricultural product. Hemp grows without pesticides and herbicides, and is much stronger than cotton cloth.

    We're only touching the tip of the iceberg here. The point is that people simply don't realize what hemp can do, because the government's blackballing job has been so effective. I'm hoping to at least enlighten a few /. readers, and hopefully spurring them to check out some websites that I'll list below and spread the word.

    Here's the short version of why hemp is illegal:

    -Major corporations such as DuPont, Monsanto, Dow, ExxonMobil, Lilly, etc. stand to lose MILLIONS, if not billions, of dollars if hemp were allowed to be used to its potential.

    -It is simply TOO EASY TO GROW. Sounds absurd, right? It is. Hemp grows in virtually any environment with virtually no need for chemicals. In short, any Tom, Dick or Harry could become a hemp farmer. The government does not like not having absolute control over what is grown. Tobacco seeds, for instance, are carefully controlled AND TAXED by the US government. They would have a very, very tough time trying to control and tax hemp growers.

    I'm really tempted to dive into the THC-friendly portion of this debate. :) But I don't want to drone on or piss anyone off.

    Whether or not you support legal use of marijuana should have no effect on your support of legal hemp cultivation. Please keep that in mind. They are completely separate issues.

    In 1957, Congress passed the Price-Anderson Act. This law caps the liability of nuclear-plant operators, and it exempts the companies that build, design, and supply parts to nuclear power plants from any liability at all. The law was passed because insurance companies refused to underwrite nuclear plants (remember, this is before product-liability suits became an industry unto itself). Price-Anderson was set to expire in ten years; people expected that by that time, reactor safety techniques would be better understood, and insurance companies would know how to assess the risks.

    Of course, the law is still on the books; it's now set to expire next August. Cheney has been quoted as saying that if the law is not renewed, nobody would invest in nuclear power plants. In the meantime, if there's a catastrophic nuclear accident that causes more than $9 billion in damages, the victims will have to ask Congress for aid -- and if Congress did provide it, how much do you want to bet that people other than nuclear-plant operators would be taxed to pay for it?

    For those who are interested, visit the HubbertPeak website where you can read up on how North America will reach maximum methane "Production" maybe this year or next. Then please realise that the word "production" really means "depleation".

    Gas well declining production rates for wells drilled today are between 30% and 50% per year. 10 years ago the decline rates were under 20% per year because bigger gas pockets were drilled.

    There are many many pockets yet to find and drill, but the combined output of all of these increasingly small pockets will not make up for the declines from the large pockets found in the past. However we look at it - we are going over the top and in very short order.

    When this happens there will be a rude awakening. The population is presently quite ignorant of the amount of methane that can be supplied. Within 2 years I expect that the economists will be telling the exploration geologists and engineers that they better get busy "producting" more fuel at which point I expect the response will be "and from where would you guys like us to get it?" The warnings are being ignored.

    For those who are interested, please review this artical on the declining production rates from the North Sea.

What these plots show is that the first 13 feilds collectively produced more oil that all of the remaining 100's of fields combined. On page 7 you can see the cummulation of all fields in one graph.

    If one looks only at the top of the curve - the combined production rate - then one would probably conclude there is no problem. Production generally has been increasing from the North Sea for the last 25 years.

    However if one looks at the individual field production rates the picture looks a LOT DIFFERENT. North Sea prodution has peaked and the production will drop by probably over 7% per year henseforth. This represents about 1/2 of European oil production.

    The giant Ghwar field in Saudi Arabia will peak very shortly and when it does the Middle east will not be able to sustain its production rates either.

    North American Natural gas production is probably already at peak. There is a minor decline in demand presently which explains the lowered prices.

    Please understand that gas wells depleat faster than oil wells. Its like the air in the tires of your car.

    A tire will "whosh" for a while if you take out the valve stem - then suddenly it stops "whosing" and the tire is flat. Same with a gas well. If you have a really big tire and a relatively small hole in it, then the tire may "whosh" for a long while. But it eventually will go flat. When a gas well goes flat there is nothing to fill it up again.

    IMHO the only alternative is Nuclear. However I'll be very happy to see all usable alternative energy sources tapped first.

    Of courese, nuclear is not politically correct. Natural gas is. This is why companies like Calpine (CPN - NYSE) are planning on building so many natural gas fired power stations that they alone will burn up all the natural gas that can be "produced" in North America by the time their plants are built.

    Free enterprise is a wonderful economic system and I suppose it has pursued its insanities in the past.

    A few years from now I wonder who will be questioning the wisdom of building all those gas fired power plants?

Some stats can be found from the Baker Hughes (BHI - NYSE) rig counts. In order to increase the prodcution rates and supply the increased gas that Calpine alone wants - the Gas and Oil drilling industry will need to probably more than double in size.

  155. My stock 1986 Jeep runs on Hydrogen by GMontag · · Score: 2

    Yes, I mentioned this a few weeks ago. Updating the info for those that are tracking my incredible Jeep project.

    OKAY, my 1996 Jeep Cherokee Sport has transported me over 242,000 miles using nothing but hydrogen based fuel! The stuff is a special hydrogen and carbon molicule and that is blended with a few other chemicals too. This special blend packs a whopping 87 Octaine ((r*m)/2 method)!!

    Now I have to go to special distribution centers to get my fuel, as opposed to , these other hydrogen fuels that can apparently be found under the closest rock or spigot, based on the frequent stories. They are kinda rare, and if you don't know what they are you would think they are little grocery stores with funny looking "scrubbing machines" housed next to the store.

    Actually, these places called "Exxon", "Chevron", "Mobil", "Shell" and "BP", to name a few, are the places where you get this super secret special hydorgen fuel! They are so numerous that if you don't have enough fuel to get to the next one then you are either broke or had a "blonde moment" and forgot that you needed more hydrogen-carbon liquid.

    My good old Jeep holds enough of the stuff to travel around 400 miles at (get this!) 75 - 80 MPH! I have never been anyplace in the USA where I had to trravel farther than 400 miles to find another hydro-carbon distribution center.

    This hydrocarbon stuff must be flowing like it is nobody's business too, since the price keeps dropping and dropping (hint: use adjusted dollars). Get this, today the MOST I pay for it in Northern VA is about $1.30 per gallon and I can go about 20 something miles on JUST ONE GALLON. Lots of that price is taxes, since it seems the government does not want anybody to have any hydrocarbon and the producers just keep dropping the price anyway. I keep hearing that it is being "depleated", but you sure can't tell by the way that market has gone.

    The "scrubbing machines" at the "secret" hydrocarbon dispensing stations use that water fuel you guys keep talking about. I use the stuff to clean off my Jeep and dispose of other wastes. Maybe the scrubbing machines use it for power too?

    BTW, if you see any big buildings that say "Jeep" on a real tall sign out front, that is where you can get one of these miricle machines. There are tons of other brands. Very feminine girls, and guys that wish they were girls, buy things called "cars", like the Miata. Kewell chicks and regular guys buy trucks and SUVs. My Jeep is called a "Sports Utility Vehicle" (SUV) and is similar to a "truck". If you are not familiar with them try a google search. Nowadays, the financing is very reasonable too. Almost 0% interest loans available on many different brands!

    Not sure where your water cars are sold, is there a brand? I never see them anyplace! However, they may be as invisible to me as the hydrocarbon vehicles and stations are to the guys that put these articles up every other day.

    Out of curiousity, I looked at the VisionEngineer page, but it neglects to put the Gibbs energy, etc. into the overall exergy system -- which forces even a fuel cell to conform to known mathematical formulas and systems, none of which I want to type out and explain here.

    You also accused my figures about IC engines to be drivel, because your source page shows that the state of the art for IC engines is somewhere above 52%.which is only true for extremely large diesel engines. If you take diesel engines out of the mix, the efficiency drops rather dramatically, and as far as I know there are no production automobile engines getting much more than 30%. The best non-turbine aero engines peak at around 37-38%. (By the way, I am humble enough to be willing to accept correction and update my knowledge base, if someone out there has figures showing something better)

    Rather than resorting to the math, let me point out that one of the main by-products of a fuel cell is heat -- and in the case of the more highly efficient fuel cells, alot of it. In fact, so much heat that you can use the heat in a combined Air bottoming or Rankine Cycle engine system. That particular combination can theoretically get to about 75% thermal efficiency, but I haven't seen much that convinces me conclusively that it will go much higher.

    So no matter what may be claimed, Fuel Cells are not 100% efficient and never will be. But we do agree that they have great potential to be a damn sight better than our current energy wasting IC engines.

    Now, from a terrorist point of view attacking a company like MS is not a prime target. How many people are "proud" about Microsoft? Sure, there must be some that take it as the "greatest software company of all". No, as a terrorist you want to stab the soul of the country, something that *everyone* can identify with.
    Your *only* argument is that it would impact the economy *hard*. Unfortunately for you, the capitalist dogma says that a void in a market will fill in no time. So MS gone means opportunities for other companies. Those will create jobs, the stocks of those companies will soar, clever investors will make tons of money. Since I presume that "retirement funds" are managed by clever investors, the only ones that will get hit are the people retiring within the next 5 years of the catastrophy. It's a toll to pay.
    For your argument that "companies in a tight partnership with MS" will go down, well, some will..again, making opportunities for others...others will stay, simply because they will put the workforce behind it to save the company and thus creating jobs. Besides, if Microsoft explodes suddenly, would your Windows 2000, Office 2000 CD's, IIS CD's go stale from one day to the other? I doubt so.

    Biological attack: yes of course, anyone would get scared, but *that* is the point of terrorism. The only thing that counts is "bussinness as usual": Do you see pilots sh*t in their pants because some terrorists could hijack the plane and crash it somewhere? Nope, most say they will go on as usual.
    Any smallpox attack on a larger company would result in stronger screening of employeess, tighter security in the buildings, etc... Vaccination would reassure employees at least a bit. Let the cowardly go, if they want, not a good choice in the current economy, isn't it? Facing death each time you go to work? The "facing death" part is ridiculous: I face death each morning because I go to work, I might slip over the soap while showering and break my neck, I might skid on the slippery roads on my way to work and crash into a tree, I might fall in an elevator shaft because the elevator malfunctions... Living is facing death, in small probabilities, every day. Now, in your eyes those probabilities have risen for MS employees, in my eyes those probabilities have risen for everyone.

    H&M....I don't know if it's true that people stopped eating beef during the crisis. I just think they wanted to show the consumer "look we are doing something", that this implied killing millions of innocent healthy animals is outrageous. Well, I and my whole family didn't stop eating our nice steaks during the H&M crisis. Neither KJD had an impact on our eating habits. Why would it? The problem was identified, and (too extreme) measures taken by authorities...everything is okay. The public always panics easily, but it is so easily soothed. Look it only took a couple of millions of cows to sacrifice. Besides, it is just what your president is doing: soothing the public by attacking Afghanistan, sorry, I mean "the terrorist camps in Afghanistan", because "We are not the enemy of the Afganistani People".
    Your only premisse is that the "public" is dumb and uninformed. Probably true, but if it is, just give it another point of attention and you are done. Manipulating people is easy, you know.
    Even if ranching is so important to the US economy, do you really think those ranchers are going to sit there and weep. No, they will sit down, weep, wash their tears away and get going like real enterpreneurs.

    Look, you don't need terrorists to destabilise a country according to your statements. Yesterday, in Belgium, the national airline went bankrupt. You can imagine that it will make a *lot* unemployed people and that a lot of other industries (travel agencies, cleaning companies, catering services,...) are heavily impacted by the bankrupcy. So it will impact on Belgian economy, sure... This "destabilisation" is caused by incompetent management and it cost about 0$ to cause....only incompetence.
    This all, just to prove you that terrorists are just only one new factor that can cause harm to a country.

    Now for people hating the US. They probably have a reason, don't you think? Even if the reason is valid (in their eyes), how many will become terrorists? Not many. Probabilities are slim, and that is the whole point. People will die, but that doesn't matter at all...people die every day, that's just because their time had come.
