Capacitor Experiment

04/12/2007 1:20 PM

I have here an experiment and I wanted to ask what you guys think about it.

I know that capacitors are very dangerous, but I think that in this case it is not so much. Isn't the electricity only running through it without charging it?

Input 220V AC/ Neutral, Rectifier 400Vrrm, Capacitor 3300uf/400V, Fuse 20A, NaHCO3 0.5Mol solution (If the picture is not readable)

I would like to have serious statements.

thank you

The bridge rectifier diodes are set up incorrectly for a start and yes the capacitor would be charged. so far all that will happens that you will keep blowing fuses. If this is the best you can do keep well away from all electricity.

Re: Capacitor Experiment

I actually work on and design substations and the like and it is not uncommon for me to be tinkering with 33,000V and fault currents in the order of about 0.25MA (that's not a typo, 1/4 of a MILLION amps). My new toy is a device that will simulate a fault on the high voltage supply network of this country (think shorting out the output of an entire power station thru a single wire).

Why did I start by saying all this, well I did it to prove that I know a little about doing dangerous things with very dangerous voltages and currents that don't just make things go bang, they make them disappear, so believe me when I say that

WHAT YOU ARE DOING IS EXTREMELY DANGEROUS!!!!

AC AND DC Voltages at this level WILL easily kill you. Any wrong move or mistake on your part will likely result in your DEATH. Given your previous posts indicating your level of experience you WILL make a mistake (everyone does, even the most experienced among us) and you will very likely kill yourself. Even turning off the power and touching the partially charged capacitor accidentally will likely result in death. Given your comment confusing using ac and dc charging currents on a capacitor, this would have been very likely (rectified ac WILL charge up a capacitor).

I must strongly suggest that you do not attempt this at all!!

I myself would not attempt what your doing without protective gear (safety glasses), a protected power supply, barrier(s) to protect me from the experiment, a fully stocked electrical lab, and an assistant on hand trained in CPR.

If you really must do this, stick with a battery supply (around 6V say). Even then there are dangers, and I am not just talking about electrical ones.

Three cheers for your well exprssed opinion, far too many medal with things they know nothing of and most often end up hurting more than their pride.

Let us assume he does not kill self. what does he want with a very low efficiency electrolysis of that solution (whose name is not clear).

It will heat it up and some will decompose and you will get a scattering of all possible decomposition products. Hydrogen Oxygen, CO2 (if that is a carbotate or ?) and some alkali from any sodium reduced. All in all, a large mess.

Suggest you tell us what you want to do. We will then suggest something

It is maybe a very low efficiency electrolysis but the electrolysis is not the effect what i want.

this picture shows what is happening at 220 VDC, 4-5amp

You are obviously using a packaged bridge, correctly wired. It is just not correctly drawn.

So some sort of thing is going on that dissipates 1000 watts more or less.

I suggest you wear safety goggles

I do wear goggles and rubber gloves all the time

The amazing part is that before this strong reaction is coming and it is only a normal electrolysis with low output, it takes 7-8amp and then when the strong output is coming the current is going down to 3amps.

Re: Capacitor Experiment

In my very young and silly days I rigged up a similar device although my intended outcome was much different. Take a diode/capacitor voltage doubler circuit (details deliberately sketchy!) and plug into 240v AC. Unplug, then short capacitor output. Result, big bang and blue flash. Only to be done whilst science teacher is out of room and apparatus to be well hidden before his return. Unfortunately someone else borrowed said apparatus and forgot the vital unpluging step. Took out a fairly major switchboard and half the schools power. Ahh, memories!

Now I'm older and wiser I'm amazed we survived some of these "experiments". I also reckon we did the school a favour. Fancy a science lab power supply being so vulnerable!

Re: Capacitor Experiment

For eighth-grade science we had class in the chemistry room where they had all these 'islands' with sinks and gooseneck faucets and - outlets. The outlets were controlled by a switch at the teacher's desk. Most of the time they were off. So we'd test the outlet to see if it was live, and if it wasn't, we'd unscrew the cover, take out the outlet, wire the hot and neutral together, and then put it all back together real quiet like.

For eighth-grade science fair I submitted a ruby laser. The power supply (which weighed a ton it seemed) and the laser head were separate, connected by high-voltage, high-current coaxial cables. My dumbass friend thought it would be fun to disconnect the 25 kV flashtube trigger at the power supply and then punch the 'fire' button. I turned just in time to see him thrown against the wall. He wasn't killed, dang it.

Small coins behind light bulbs was as far as we went in the deliberate sabotage area. Isn't it interesting how many people in technical fields have similar stories of behaving badly in school years. Perhaps schools should have an alternative curriculum for their more technical miscreants.

You should see how long it takes several electricians to find a 5c coin, the first time anyway!

I would draw an arc from the flyback transformer of a TV to my finger in electronics class and encourage the others to do the same. "See, it wont hurt you!" Needless to say my instructor nearly had a fecal hemorrhage and asked me to cease and desist.

The Aeromodelling Society used to meet after-hours in the Biology lab. One of the experiments was to see how much balsa wood a gerbil might eat in an hour-and-a-half...

The other worthwhile experiment was to connect the Biology lab's 20V, 20A DC power supply across both sharpened ends of a pencil and see how much smoke could be made...

Happy days.

I used to draw a really nice arc of the long wire antenna on my ham rig with a pencil. I'd also charge myself up with high voltage DC and carry a fluorescent tube in and touch the end of it to light it up. Scared the crapp out of my mother.

Your motto says "The world is a free place for free minds", but if you use the circuit shown, there'll be one less free mind in the world.

The circuit would be to either boil the liquid in the jar or if the electrodes are to close, blow the bridge and then the fuse.

I'd suggest you buy an adjustable power supply 0 - 24Vdc ~10A and do the experiment with that.

In actuality, the circuit shown will do absolutely nothing if connected since you will always have two rectifiers back biased. However, since it is clearly a random guess at a circuit the comments warning of hazard are certainly in order.

You can dispense with the capacitor. As your load is essentially a short-circuit, your capacitor only adds bulk. If you don't want your electrodes exposed, replace that part of your setup with a Vick's Vaporizer. Conduct your experiment well away from flammable materials, plug it in, step back, and watch it self-destruct.

As drawn it won't self destruct or anything else. Now if one were to reverse the orientation of the lower two rectifiers things begin to get more exciting. Make sure you video it so we can watch it on youtube. Bring on the magic smoke!

Re: Capacitor Experiment

04/13/2007 7:43 AM

Yessir, Mr. Capper, but it's not a bad idea to suggest what might happen when our intrepid experimenter follows others' suggestions on this thread and connects the bridge rectifier properly. Sooner or later the OP's gonna connect the rectumfrier properly just to see what happens. This is one of those "just to see what happens" experiments, I suspect. I'm guilty of a few of these, btw. (Ever hit 15 wvdc tantalum capacitors with a defibrillator? hehehe) And notice that our experimenter shows the circuit powered from one side of the 240 VAC mains and neutral, which is simply how a regular 120 VAC household circuit is connected at the breaker box. If our experimenter really intends to apply the full 240 VAC across this load, forget the neutral and connect to the other 240 VAC mains branch. Still, how does this setup constitute a "capacitor experiment?" Any idea what the OP has in mind besides making a potentially-lethal mess?

Re: Capacitor Experiment

I figured maybe he was intending to make hydrogen, which of course he will regardless of his intent. I have a few steel case TO3 transistors with holes blown through the tops that I "made" once testing a power supply I had designed that had to be short-circuit proof. Obviously the first couple of attempts didn't quite get it right. I of course took due precaution (goggles, hearing protection, fire extinguisher...) before slamming the screwdriver across the terminals. I not only got the magic smoke but some magic fire also came out of those transistors. I have let my share of the magic smoke out of parts. When I was just a kid I let my first magic fire and smoke out of a selenium rectifier. That was very educational! Not so much these days since most of what I do anymore is micro-power. I miss the magic smoke. The magic smoke is very educational and with proper precautions fun!

Smoked, burnt selenium rectifiers stink. Boy do they stink. These are the ones that look like a stack of square (or round) 'fins' separated by spacers?

Years ago one of my co-workers carelessly wired his big electrolytic caps into a power supply backward. A big bank of 'em, too. The supply was "acting funny," he said, and asked me to come take a look at it. Just as I peered over the caps, the pressure seals blew, spraying my face and eyes with hot electrolyte. He didn't last long.

Yeah, they do stink! I have had the cans blow off electrolytics and whiz by my head. I was just telling someone the other day that I've always wanted to build a tesla coil. A really big one of course. But the novelty would wear off and I already have quite a lot of junk sitting around.

That seems so obvious as to go without saying but perhaps I give more credit than is due. For anyone who has been asleep since birth, if your momma didn't tell you not to stick anything in the light socket 'cause it is DANGEROUS, then be forewarned: Electricity is dangerous and can kill you. Also the stove is HOT so don't touch it. Oh yeah, don't stare into the sun or a laser pointer for that matter and don't run with scissors. Don't cut toward yourself with a pocket knife. Look both ways before crossing the street. Don't tug on super man's cape, don't spit into the wind and don't mess around with Jim. How's that?

Re: Capacitor Experiment

My son and I were sitting behind the pastor's snooty wife in church one sunday. It was a small church, and she was the self-appointed music minister. Caroline had the worst singing vibrato imaginable. It would waver at least a full flat and sharp around the note she was singing, at about 5 Hz. And loud, too. Listening to her lead the choir was akin to riding in a car having one highly elliptical tire.

My 6-year-old son took it upon himself to mimic her, sitting directly behind her, and he did a fair job of it, also very loud. Turns out that particular musical passage contained a nice long, two-measure rest, whilst Joe continued singing the previous note mimicking her horrible waver. The whole church heard it and went dead silent. Then some kids in the back cracked up, then some adults. Then some more. She shot around and glared at him, then at me, with knives in her eyes, her face beet red. After church I gave him a high five.

How do you measure "works really well?" What are your criteria? Can you say what the ripple voltage is across your cap? Have you looked at the waveform? "Works really well" implies comparison against a standard of "working well." What is your standard?

Efficiency is NEVER over 100%.

That is free extra work and it NEVER happens. Trust me.

If you think you are over 100% in any activity, then your assumptions/calculations are wrong.

Did you buy this idea from some con artist, I mean respected scientist?

sorry then I wrote it wrong

It is hard for me to explain I hope you will understand.

the the output(heat) is greater then the input (electricity)

It is only understandable for me with a nuclear fusion or something else what I maybe haven't heard of.

examples:

input (Joules) output (Joules)

43500-----------61651

31793-----------60468

That what I measured and there are other people who did the same experience.

What do you think about that?

You measured this? With what? A voltmeter across your electrodes, as shown in your diagram? You've got to be friggin' kidding me!!! Rager, if you think you're gonna pull the wool over our eyes on this forum, think again. All told, there are probably several centuries of combined, direct engineering experience represented on this forum at any given time. Your credibility, such as it is, has sunk to absolute zero. Zip. Null. Nada.

Take your fantasies - and your light bulb - somewhere else. For my part, I absolutely cannot stand your duplicity.

Rager is simply a victim of his own lack of knowledge. This is a classic example of "Bad Science". When you do not know how to correctly calculate and account for the observed effects then you end up operating on assumption and further assuming that that is fact. Rager, you would probably require several years of additional hard study before you would have the ability to correctly asses your experiment and account for all of the variables of which you are currently unaware. Were you to do this you would discover that your hopes for free energy are not going to be answered by throwing a couple of electrodes in a solution and plugging it in. I mean really, think about it. If it were that easy (more accurately I should say "even possible"), isn't it just a little bit naive to think that you would be the first person in history to have discovered the answer to man's energy crisis? Please, get real son.

I beg to differ, Mr. Capper. Rager's citing values in Joules given that rig of his and given another thread where he inquired about how to use a multimeter goes beyond just a simple lack of knowledge. Lack of knowledge doesn't fabricate figures in Joules. I don't care what the "experts" say. I know bullshit when I see it and this is bullshit. If this were a cardgame, I might play. But it ain't. And I hate duplicity. Lack of knowledge can be fixed through education - provided the student is willing. But duplicity is a character flaw. And a voluntary one at that. This crap is an affront.

Perhaps you are correct Sir. I am inclined to place it somewhere on the continuum between ignorance and stupidity but no doubt I have at times been mistaken, or duped, as the case may be.

I think the use of Joules and the multimeter useage indicate a person picking up bits and pieces of knowledge from here and there via self learning. Had he been instructed his knowledge would have been little rounder.

I suggest he try this resource and start at the basic levels.

To bad he didn't pick up a few bits and pieces of intellectual honesty along the way. Honest inquiry with integrity is one thing - and welcome. But that isn't what we have here, IMHO.

He had (in his mind's eye) come across and idea worth, potentially, billions. He was just being guarded, as is possible with non tech people who have a flash of insight they think has merit. Us jades know better...

I learned how to use a multimeter. it is not that hard, but I only wanted to be sure that I don't blow it.

Marvelous! So why are there not free energy machines being touted in all the media? Don't you understand that if in fact someone had made such a device that they would be on the way to becoming the richest person in the world and that it would be shouted from every roof top that free energy had been discovered? Just try to step back for a moment from you key-hole view and think about the big picture. Do you think there are people suppressing this technology? Why? How could they even do so once word leaked out that free energy machines were actually in use? Just think this thing out because if you persist in speaking foolishly then we will make the natural assumption there from. Or perhaps you are just pretending, jerking us around, in which case you are petty and malicious. Please just go away. You are annoying, you do not listen and perhaps you are just attempting to waste our time. If you really are 17 then you are arrogant to assume that you are smart enough to even correctly asses what you view on the internet. By the way, when you make a big wad of money with your free energy machine, I have a device that turns electricity into thrust, and inertial engine. It just needs a little more work to make it commercially feasible and for just a couple of million dollars of investment I'm sure I can work out the bugs! Let me know when the check is ready.

I do not think I would do any electrochemical experiments at quite this voltage. As stated, you need to check your diodes. I cannot tell what the chemistry is in the cell. If it is fairly low resistance, you are going to blow a fuse. If it is low concentration, or not ionized you will draw little current and do a good job of charging up the capacitor. It will then hold a charge after the system is disconnected for a period of time.

Sorry, did some more reading, .5 Molar sodium bicarbonate, the capacitor is not much of a problem but this system is going to get hot while (I think) it generates sodium hydroxide (drain cleaner). Don't try it, it will probably splatter hot caustic all over the place.

Safety Tip: One suggestion for the OP is to connect a regular 60 to 100 watt incandescent light bulb in series with his load. It wouldn't be a bad idea to current-limit the thing as the water boils off leaving an increasingly-conductive concentrate behind. Even if the solution becomes a short-circuit, the current won't escalate beyond that used by an ordinary bulb.

NaHCO3, if you electrolyze this in water it will create metallic sodium, H2O and CO2.

The Na will decompose the water locally to form NaO which will immediately hydrate to form NaOH which is a strongly ionic compound and will exist as Na+ and OH- ions in the water.

The Ph will be strongly basic,

That means as longer it is running as stronger is the ionic concentration going to be, right?

Solubility of NaHCO3 is 7.8g/100g water @ 18C (64F), so you will run out of dissolved NaHCO3 and that will give you about 3.6 Gms NaOH in that 100 CC of water, 3.6% by volume and about 7% by weight.

What is the end use of this? NaOH is one of the cheapest chemicals to buy

Whomever tried to talk you into doing this experiment is not your friend. This is a very dangerous design.

There is power on both AC input wires- no neutral. Two wires for 220vac means both are hot but out of phase.

with correctly setup diodes you will have over 500volts on the lines after the bridge. At 20 amps this will soon boil out the water to a very strong less resistive liquid. Think flash and burn.

the AC fuse will eventually blow but the DC will still continue to heat the now concentrated liquid.

what outcome do you suppose will happen then.

How will you safely dispose of the concentrated fuming residue if you survive this experiment?

Sounds like the blind leading the blind. 220 x 1.414 =311 volts max at the capacitor. And once the fuse blows there will be no AC and if there is enough current flowing to blow the fuse then a few milliseconds after it blows you can be assured there will be no DC. I'm not saying this might not be hazardous but at least get your facts straight.

Rager

I think youthful curiosity and the willingness to learn are commendable attributes. But based on this experiment and a previous post about ammeters and multimeters I think you need a personal tutor to be an on site monitor and protector.

I have personally seen the human result of arc flash and electrical explosion. In the cases I have seen it was not fatal -- BUT it was very permanent, and the worker will be reminded every time he looks in the mirror, worse yet each time he bumps his face the skin still peels off easily.

Be smart learn the basics before you hurt yourself, or worse yet one of your interested but unsuspecting friends who may be watching or helping you.

Hi are you still with us?. Don't do a thing yet!. Don't give up!. You can get some help from books on "how to build power supply's". Or, on line info is vast. ? Are you trying cold fusion exp?. Please use extreme caution when charging caps, go to Rail gun stuff and see how they do things. Beware, stored joules is deadly. cap power math in short 1/2 times voltage stored times cap value equals the joule energy stored hence.

{.5*600volts*25mfd=7500 joules}You can vaporise steel at that power level.

I don't think our OP has to worry much about stored energy in this particular experiment. Whatever that cap might have otherwise stored is gonna be bled off by that load, real pronto. That is, once he connects that bridge properly to get any current at all. If the OP is in any danger, it is from that direct connection to the mains.

< wanted to ask what you guys think about it.>

April fooling?

As drawn-no current will flow--diodes have to be rearranged with all "cathodes" pointing UP-to enable Bridge Rectification.

Capacitor is redundant. What good will come of peak Charging?

Electrolyte will not mind the full- waving----will average out.

And people Survive out of INSTINCT(for survival). You will too!

What will you learn/teach anybody -doing this experiment after reconnecting diodes to allow current pass through electrolyte( even if fuses do not blow,and electrolytes splash and make a mess)?

!!! SWITCH OFF FIRST BEFORE RUSHING TO CLEAN UP MESS!!! -should be the signposted theme Warning all around!

That is what I THINK of your 'Ex-peri- ment'.

As somebody said 24Vout Tx!-

Use a Variac ,after reconnecting diodes and removing capacitor.

References seem to point in the right direction but I am baffled as to how Rager can possibly believe that he/she has developed working cold fusion (I am not even going to get into what's wrong here) without the aid of the following two critically important things

1) Basic knowledge of nuclear physics.

2) Basic knowledge of electricity (I count not knowing how to wire an ammeter in a circuit, and not knowing how a capacitor reacts when dc is applied across it as NO knowledge in this area).

Rager is way out of his depth here. I think it is time to go back and learn the basics.

My concerns revolve around the end item. Not too long ago we had seemingly innocent people learning to fly 747's. Not an accusation just a serious concern about heavy water, capacitors, physics. He really has not mentioned a use or intention for this stuff. Probable a needless worry, as it seems he is not posting responses or questions any longer. Sorry if I'm too serious -- But there have been some horrible things happen in the last 10 years globally.

Did you read my posts at all? Please try to stay calm and instead of using broad generalisations please provide the links to the people you are saying have actually done it, as I have never found any. Proof is necessary, especially when something as monumentally important as the discovery of cold fusion or free energy is being touted. If I said that, not only did I meat Jesus (he is a Draco by the way), but he also gave me god like powers to alter the laws of time and space AND the ability to give these to others, wouldn't you want some fairly serious proof? This is what independent scientific verification is all about (this is how the real world works).

Are you still there?

I really sorry with the generalisations but I don't want to tell too much.

Re: Capacitor Experiment

04/18/2007 6:54 PM

With regard to proof, I am only after the website links that you are basing your research on. Given your level of technical expertise that you have indicated I am assuming that the bulk of your knowledge and research is based on information from these websites. Now, since you do not have the expertise or necessary equipment to prove such a discovery it is always necessary to go back one step and assess the foundations you are basing your research on. If the foundation is built upon false claims (or outright free-energy scams) then any research and development that follows will obviously be flawed and will almost certainly lead to a dead end (due to trying to do something that is scientifically impossible).

When undertaking any research or development project it is VITAL to ALWAYS ensure that all information you are going to use is factual and true, before continuing. This prevents wasting a great deal of time chasing red herrings. You must never assume anything (imagine if the media did this, well all the time). Due to the viral nature of information exchange in the modern world (mass media, internet, etc) it is very easy for a single false claim to spread, with many referencing it. Soon so many people are linking to it and building on the idea that it becomes believed as true, just due to the shear number of people linking to it (even thou it is not). A case of "if so many people are linking to it on so many websites, it must be true". Never believe anything on the internet unless you can prove the source is reliable, and certainly never believe any extraordinary claims unless they are backed up with extraordinary proof from multiple reliable sources, and even then only believe if you can personally replicate it and prove it to yourself.

This is how the research and development industry works in the real world.

Your material, such as you have, seems to have already convinced you easily enough. To have proven to you the viability of what you are trying to accomplish. Why do you assume it will take so much more to convince us, when it has apparently taken so little to convince you? Are you a sucker?

Well, you can not make an energy generator out of salt water. There is no magic road or secret that will allow a 'new' method to do this.

All aspects of the various reactions with Deuterium and Lithium and Tritium have all been inspected in great detail over the past 100 years.

The only places that say you can are usually con men on the web who want to sell you a set of starter plans so you can use your superior brain power to perfect this process. They will also sell you assorted materials to help you along the way. All these require your money. None of which is worth anything at all. It is just a scam for profit and you and people like you pay your money and build these worthless pieces of apparatus that will never make energy and can kill you if you are even slightly careless.

Let us say we have free money lying around. How long before people line up for it. Same for free energy. The sun gives us unlimited free energy. 1000 watts per square meter(more or less) and if we can solve the methods of recovering 50% of this cheaply we will need no more reactors. Right now we are in the 15% range for low cost and experimental ones are in the 40% range(but fragile and too costly at this time)

I won't use the capacitor until I know more about it.

Hey and you don't have to make fun of me!

If you want to make fun, keep it to yourselves.

I try to make here something serious and It is hard enough without all the jokes.

Actually people aren't so much making fun of you as trying to tell you in a variety of ways that this is a damn fool idea and if you keep tinkering about with these voltages you are going to kill yourself.

Go back to the top and read Jack of all Trades original reply, then sit down and think about it. Death is very permanent.

Death is nature's way of telling you to slow down...

Or perhaps to give up electricity.....

Jack's back (internet was down).

There is a lot more discussion on this thread than there needs to be. Please refer to my posts (including post 36).

I have seen this all before (so many times), and what you have is NOT cold fusion, it is mearly a lack of understanding on the basics of electricity and chemistry, coupled with poorly implemented lab results that are hinting at things that are not there. What you are experiencing from other users is shear frustration at something that is very obvious to them but that you cannot quite seem to understand (due to a serious lack of knowledge and real world experience). This is however not entirely your fault. Let me guess, you found the information and data or the idea on a free-energy website and wanted to pursue it to help make the world a better place (or make a fortune). Please, please, please, please................... please don't believe everything you read on the web. A 12 year old child with a free afternoon can make a professional-looking website that can fool even the most experienced at a first glance. This sort of thing preys upon the inexperienced without education in the specific areas of electricity (and in this case chemistry, physics, etc) who really want to make a difference in the world. Without this real-world knowledge and experience you are unable to question the results and data you are looking at and know which claims are possible, and which are down-right lies (eg- free energy).

Please don't ask for a detailed explanation here on proving why this is not cold fusion, I doubt anyone would bother given the fact that when we usually try, the person refuses to listen, assuming that they are right, no mater how much data is put in front of them. Belief is a powerful thing that many times even logic and truth cannot sway.

Remember extraordinary claims call for extraordinary evidence (especially when it comes to cold fusion over-unity power generation) and the real truth is no one who has ever claimed over-unity has ever been able to produce even a decent amount of evidence or a test that can be repeated by a second independent party. Not the universities, not the backyard enthusiast, not the people on the free-energy websites, no one. Current development by the various government's cold (and other) fusion programs over the last few decades has resulted in 100's of millions of dollars spent but nothing close to even unity. The worlds experts who have devoted there lives to this cannot make it work, now do you really believe the free-energy websites showing numerous backyard tinkerers with no experience or education, $10 worth of parts and proof in the form of a picture, can do what they cannot. The answer is no.

To summarise, before you can walk you must learn to crawl. You have to learn the basics of electricity and chemistry first before you continue even playing with experiments this dangerous. After you learn the basics, move on to the intermediate level of electricity, chemistry and physics. From here you should see for yourself why what you are trying to do will not work.

Remember there is no free lunch, you cannot get something for nothing, if it looks too good to be true it is, and in the research and development field you cannot rely on anyone else's educated opinion until you can at least understand the overall big picture of what you are trying to do.

I have taken the time to write this, please take the time to read it.

You need to drop by KiwiNet and kick some tech booty. How dare they!

Welcome back, Jack!

What's the web address (there are over 10k hits for Kiwinet).

Ooooh, lunch time. Time for me to......hit the road, Jack, and don't you come back before 4:00 before 4:00 before 4:00 before 4:00.

Perhaps an interesting (and safer) field of research would be "What are the ingredients that make a thread develop a life of it's own". I think one ingredient would be a silly question to start with. Sensible questions get sensible answers and soon die.

I read a book once (Running Blind, I think) where the Americans built a device incorporating all the unexplained technical pecularities they could. The idea being that the Russians would steal this and it would tie up their best brains for years trying to figure out what it did. Expand this concept to CR4 and think how many hours get devoted to fundementally silly questions.

Is it all a plot?!

Usually if the thread contains any of the following you know you may be in for the long haul.......

Free-energy, global warming, religion, Tesla, etc.
