The causes of global warming are so intertwined that it is non-productive to attempt to place the blame squarely upon a cause or even several causes. My personal belief is that humanity is largely contributory, combined with the effects of coincidental natural events which are occurring now and have happened similarly in the recent, not geological, past. Therefore, over-population of the earth by human beings has now begun to present a factor in the eventual demise of humanity, like it or not. imp

Have you considered the fact that bio-engineering of food products and basics has created the ability of producers to become captive-market controllers of parts of the human food supply? For example, if you raise corn, and seek to purchase seed to plant your crop, today's offering of seedstock consists almost entirely of genetically-modified seed which is sterile- that is, you can only get one crop. Next time, you cannot grow more using seed from the previous crop; you must buy MORE of the "scientifically superior" seed. Why is it better? The sellers claim increased insect tolerance, lower pesticide need, larger yield, higher nutritional value, and so on. Monsanto Corp. now introduces an e. coli gene into it's corn seed stock. So, how do you feel about eating product thus related to intestinal waste? Or, will you only sell your crop to an unsuspecting public? imp

Global economy proliferation has been made possible by the computerization of society and the hunger for ever-increasing revenue by enormous multi-product industries. The "Mom and Pop" stores are largely gone. If the standard of living is gauged by considerations other than personal income, how many toilets & cars one has, and how big his/her house is, it seems some countries abroad easily approach ours (America's). Yes, policing the world should definitely by reduced, as it simply increases dissent and distrust of the U.S. imp

Get on you, or ingest by swallowing or breathing? The latter is especially vile: plutonium, beryllium, aspergilla (mold)- bad to breathe! imp

What will the Ph be of the distilled water produced by the device? imp

One of the mfrs. used to supply their dealers with a "light board" to use for display purposes with their microwave ovens. It consisted of small neon lamps placed in a lattice with spacing of about 2 inches between each lamp. The board was of such size that it could lie flat on the floor of the oven. When turned on, the radiation ionized the lamps in a rather fluttery sequence of lights, rather eerie-looking. Their main intent was to show that some ovens actually have "dead" spots in them, and the lamps do not light at all where such places are. If a dead spot is found, and a small container of water is placed there, it will not get hot. The way in which dead spots was overcome is to provide a rotating turntable, or a "stirring fan" in the waveguide which alternately disrupts the movement of microwave energy. You can easily build a light board by simply taping some small neon lamps to a piece of cardboard. Try it! imp

Shall we also consider those who worked scientifically, but no longer do so? imp

Thank you kindly! Most helpful for the computer illiterate! Now, if only this message were more easily sent to you via Personal Message, I would KNOW you received it, and not waste space in the thread itself. My other forum attended has an icon on every post to allow PM's. Thanks again! imp

The Museum of Science and Industry in Chicago, Illinois, USA, used to create very loud (deafening) bolts of lightning in-house, when visitors were least expecting it. If you search appropriately, you may be able to get information on their device, and whether it is still in use. My experience of it dates back to my youth, a very long time ago, indeed! imp

Thank you! Now, I need the formaldehyde to react it with other stuff, not preserve dead meat. My post title was intended to get someone to look, rather than breeze by. Your method would muddy the water so to speak with additional ingredients, or am I wrong? For some reason, they sell para- but not the water solution; believe both require haz-matting by common carrier. imp

Of course I wrote it as a joke! That was to throw off readers' considerations that the formaldehyde might be used for some dastardly purpose! Now I have to figure out some other kind of "cover". Anyhow, I really wanted to know if paraformaldehyde is easily converted into the water solution form. imp PS: No, I'm not an embalmer, perish the thought. Not even a chemist. Not even a qualified.............you get the idea. That's why I ask questions, and hopefully, people will answer them. Thanks for the help!

If you make a perfect sphere, use plutonium as the material. It will feel nice & warm to the touch. imp

Are elements OK? Uranium 234 Uranium 235 Neptunium about to become Plutonium Plutonium Any fast nitrated detonable, perhaps diazodinitrophenol, to squeeze the above Nitric Acid Sulfuric acid Mercury Ethanol Formaldehyde imp

The trick I use for understanding voltage is that voltage can exist only between two points; it does not "flow", and it does not show up as "there's 20 volts here". Here"? Where? Has to be between two points. Remembering that has always helped me. imp

This thread has stopped making sense; it's getting too hypothetical for my little abilities. So, here is my input on the original question: Is light visible? NO. Light is a certain wavelength region of Electromagnetic Radiation. That particular region "excites" the surface of objects which we "see", by virtue of those objects reflecting light back to our eyes. If we see it as "white", it's reflecting many different wavelengths, if black it's reflecting very few. Simplistic, perhaps, but easiest way for me to "see" it. imp

My simpleton mind looks at it this way: First, if primary turns are less than secondary turns, primary voltage must be LESS than secondary voltage. So, if primary voltage is 500V, secondary must be MORE than 500V. How much more? Secondary has 20 times as many turns as primary, (400/20) = 20, so secondary voltage must be 500V. X 20, or 10,000V. Study the method. Then go back to your Algebra I textbook, and see about becoming more proficient in Algebra. EVERYTHING you do in Science and Math. in the future will be VERY VERY dependent on being slick with Algebra! Believe me! imp

All replies so far correct: Summation: Any conductive paths (like 2 parallel wires) constitute a capacitor. The material between them (dielectric), unless vacuum, has resistance, usually very high, which allows some undesirable "leakage current". The data of your experiment is flawed. Initially, as charging begins, capacitor resistance is low; as charge builds, electrons gather in excess on one plate, and are deficient on the other. When capacitor voltage reaches source voltage, current flow is nearly zero, dependent on dielectric resistance (leakage current). Apparent capacitor resistance is then very high. So, the apparent "resistance" of a capacitor is not fixed, but varies between nearly zero and nearly infinity. The capacitor therefore "resists" a change in voltage. In an alternating current circuit, or under any voltage varying periodically, the capacitor circuit current varies with time as a function of the resistance and capacitance in the circuit. I hope this helps. Please ask if it does not. imp

There is always something new under the sun. Cold fusion is not one of them. imp

Shame on you for laughing at another's misfortune!! imp

Abound at http://www.berwyntalk.com Those folks are awesome! Try it! imp ##### How can an administrator realistically rate someone's demeanor? And what good is reputation evaluation iof only the recipient can see it? And, Thank you for helping me!! Best.........imp Killer, those concepts can become a breeze given good instructors, something I longed for while in school. Feel free to seek my help, if you so choose; I cannot guarantee results, but I enjoy helping out- did so for the local high school 2002-2003 by teaching Math there; the previous teacher left suddenly, and the District was in a bind. An eye-opening experience for me, as I'm an Engineer, not a teacher! imp you must be warm there, near the equator! imp Fredrik, here in the US we would say you are biting off too much to chew at one time. I once corresponded with a young man in Sweden, his name was Cato, and he was interested in the shooting sports; that was how I came to contact him, through a firearms magazine (book, not ammunition container). He stopped writing, I think, because he was offended my my casual criticism of some things he said. I hope you are not the same way. imp Hi! Tetrachloromethane would be a fairly uncommon type of chlorinated hydrocarbon in the family of what we loosely call "Freons", the destroyers of the ozone layer. I can say with certainty that water contained in the device with most freons used commercially greatly detracts from their effectiveness. Color? Probably colorless. The commoner methane based types are chlorodifluoromethane and dichlorodifluoromethane. This stuff is generally pretty harmless, non-toxic, non-combustible, heavier than air, WHAT? How does it get up to the ozone layer, then? imp Remaining "solo" keeps one out of trouble! Wish I had remained thus. imp

Guess I'm doing this somewhat due to reading the member's claim that he/she is a "grumpy bastard". I am even worse; I'm an old fart. And I'm new here, and also fairly new to "netiquette", so if people will bear with me as they perceive of my ignorance (called computer illiteracy), I will try to enhance some of the threads found here with what I consider to be a fairly extensive knowledge of Engineering experience, with splaying side-interests in Chemistry, Physics, Politics, and maybe a little Math. So, will anyone please explain why some things here are referred to as "sticky"? Finally, I will from time to time solicit input regarding information or personal thoughts on a variety of things which I either have no answers for, or things which have troubled me for some time, and remain shrouded in mystery. Imp PS: Pray tell, why does the information at the bottom of my posts include a little green square proclaiming Imp a "decent person"? Other "newbies" don't seem to have it. Therefore, are they "indecent"? Kitty, as we say here in US, you have "sold the farm" by divulging the information above! Imp Jen, both will do you good! Mine, ah, so many and varied, no one would care to hear. Do you know why some posters have their location shown, and others do not? Thank you.........Imp Elsie, now would that be Mechanical Engineering? Good for you! Please be sure to not forget to seek help if needed in Engineering, ................ Please do not hesitate to ask me if I can help with technical stuff, as I am degreed in Mechanical Engineering and Electrical Engineering. (I am really not as smart as those fancy titles suggest) Imp (USA)

Maybe? What CAN be said for the jerks who watch "House"? Imp

Must be a local code thing at work here. My house in Colorado was completely piped with CPVC (chlorinated polyvinyl chloride) plastic pipe. Supposedly, PVC is adequate for cold water only, CPVC was made for hot or cold. I didn't care for the idea of plastic pipe either. When I built my own house (in Arizona), I used copper exclusively.

happened in the desert of Arizona, near a high-tension power transmission line. It was "monsoon" season, high humidity, dusk, threatening rain, dust starting to blow---------- Then, suddenly, bluish-purple glowing around some of the insulators supporting the conductors high overhead----------- The display was so beautiful, my mind left my being------- It was as though I had willed the beast to appear-------- (Think I could write a book successfully?) Imp.

Copper piping for potable water use must now be sweat-soldered using only lead-free solder. Does anyone have experience with these new solders, regarding their relative ease of use, strength of the joint, and leak-tightness? Imp.
