Should not be a problem Not at all. Fill any bottle fully with non-compressible parts of whatever and all will survive 681psi.

Think of a light dimmer... turning the knob varies a tiny amount of current fed to a device called triac, similar to a transistor, it allows the mains power to flow accordingly. The triac conducts the household electricity more or less according to that small amount of current driving it. If instead of a potentiometer on a knob, you use an audio amplifier and its output levels variation is properly fed to control that triac, the result is electrical power modulated by sound intensity. The gadget to modulate lights to music is just a little more elaborated than a plain dimmer.

Hi all. Does anyone knows what is this pictured item ? It is about 7 to 8 inches, appears to be iron. Thanks

Not a single brick here, but some of the flat pack part; its design is to drool. Get your beach size towel as a bib now : ---> http://dornob.com/open-house-modern-fold-out-mobile-home-design/

Much cheaper would be to build condom factories all over those places, for free distribution...

About a mile from my place ocurred that San Bruno underground gas pipe explosion, got me wondering... As it left a crater and ejected a pipe section, the explosion was underground... I think. How the needed air/oxygen for an explosion to occur got into the packed pipe sorroundings? If the pipe was leaking before the event, less chance for air to get underground, as would be flushed out by the outgoing gas. I think. The fire in the gas filled pipe did not propagate inside the pipe further lenghtwise to other served neighborhoods, as there was no oxygen. The spark... on highly doubtful conditions, the spark had to happen underground... perhaps metal-to-metal grinding at the moment of rupture. Any guesses until experts say something ?

Hi. In some other forum, a beginner asked how to run a domestic clothes dryer from batteries to save in electrical power , and responses were of course, to discourage such by multiple solid reasons. I suggested as alternative to make a 'closet' with the clothes hanging and force fan-air flow, no heat added. It would take much longer time, but... Would that electric fanning take much less energy for a much longer time ending in a not-worth-it alternative than a several kilowatts for only a couple of hours domestic clothes dryer ? In other words, would indoor clothes drying need to use the same amount of energy no matter what the method ? I do not think so, but would like comments. The extreme is just leaving clothes hanging for a week? indoors, they will dry anyway for $0

The battery itself has no power enough for that bulb. Try a LED instead, it glows with a few milliamperes. The amount of wet surface area on the electrodes is too small, better use foil. If different metals as electrodes, could be reversed polarity fighting against the battery potential.

Thanks, John. Would time help in the migration ? If ions happen to partially migrate under the electric field, is their (ions) interactive repulsion because they have the same charge polarity another limiting factor for greater segregation ? Ions of same charge do not 'like' to be piled up together.

Hi. If a sealed glass container filled with salty water sits on a highly charged positive plate, and on its top a highly charged negative plate is placed; would the solution ions migrate towards the plates, leaving a leaner solution at the centre ? Sort of a glass dielectric Leyden jar...

Thanks. Then instead of thinking on an absurdly tall column; what about feeding the salty water into a centrifuge ? Would then the ions float or sink, yielding some separation of the solution concentration ?

Hi. Welcome to the forum. Do some research on Hylomar applications, it could form/make the gasket you are after.

Hide the Minaret Greg Gutfield To Open A Gay Bar Next To Ground Zero Mosque To Cater To "Islamic Gay Men" By Jon Bershad | 8:23 pm, August 9th, 2010 No, this is not a joke. In fact, it is instead one of the most brilliant pieces of provocations in recent years. Greg Gutfieldfrom Fox News' Red Eye announced today via his blog that he is actively speaking to investors and plans on opening a gay bar next to the controversial mosque being built near Ground Zero in New York. To make matters worse (better?) the bar will be specifically designed to cater to homosexuals of the Islamic faith. God, this is going to be an exciting block. Here's Gutfield's entire post which he will expand upon during tonight's Red Eye: "So, the Muslim investors championing the construction of the new mosque near Ground Zero claim it's all about strengthening the relationship between the Muslim and non-Muslim world. As an American, I believe they have every right to build the mosque ? after all, if they buy the land and they follow the law ? who can stop them? Which is, why, in the spirit of outreach, I've decided to do the same thing. I'm announcing tonight, that I am planning to build and open the first gay bar that caters not only to the west, but also Islamic gay men. To best express my sincere desire for dialogue, the bar will be situated next to the mosque Park51, in an available commercial space. This is not a joke. I've already spoken to a number of investors, who have pledged their support in this bipartisan bid for understanding and tolerance. As you know, the Muslim faith doesn't look kindly upon homosexuality, which is why I'm building this bar. It is an effort to break down barriers and reduce deadly homophobia in the Islamic world. The goal, however, is not simply to open a typical gay bar, but one friendly to men of Islamic faith. An entire floor, for example, will feature non-alcoholic drinks, since booze is forbidden by the faith. The bar will be open all day and night, to accommodate men who would rather keep their sexuality under wraps ? but still want to dance. Bottom line: I hope that the mosque owners will be as open to the bar, as I am to the new mosque. After all, the belief driving them to open up their center near Ground Zero, is no different than mine. My place, however, will have better music." =======================================================

There is air ionizers for several uses and claim some effects, but would like to know if negative ions are emitted from pointy needles exposed to ambient air as in some electronic gadgets sold, by negative or by positive high voltage. (Believe negative); what happens if the high voltage on the pointy needles is alternating ? What happens increasing the AC frequency to several KHz ?

Hello. Would like to find out some details/colaboration/information about Crooke's radiometers, from any SFN member residing in Paris. Thanks

Just guessing... you want the filter to retain everything but your silica ? Is it dry or wet ? Have you tried pressure as in osmotic membranes ? Is the contaminant particles size known ? Would ultrasonics be of help ?

Hi. Salty water does conduct electricity, but after it dries, it does not. Can someone suggest some household doable type of fluid, that applied on a surface -say glass-, can conduct some electrical current after dried ? I need a minuscule quantity, about 1 cubic millimeter to restore an indium-tin oxide trace on a LCD display. Silver ink is minimum $50.

An inverter is a device that converts direct current DC as from a battery into alternating current AC as the domestic outlet electrical power. Batteries to operate them are usually 12V; 24 V; 48 V and an oscillator in the device allows the voltage transformation to higher voltage than the battery supplies, but at less current. Typical is turning 24VDC into 120VAC The DC current drawn from the batteries is much higher than the current supplied at the AC output because what is being converted is power. The multiplication of the batteries DC voltage times the batteries DC current is the Watts consumed. Example: 24V x 5 Amperes = 120 Watts power The multiplication of the 'inverted' 120 V x 1 Ampere = 120 Watts is the power delivered by the inverter device. These figures do not take losses in account. Hope it helps.

Total goof, sorry. I had the wrong figures. Yes, it is ~34 grams in a litre. That explains that such soup would not be a soup at all, but more like poison... It is ~3.4 %, but the litre is 1000, not 100

Any number of metres of your choice, it is just to enhance the question with perception of a greater differential.

Drinking seawater is known to be very unhealthy. There is 3.4 grams of ClNa in a litre; but on a 200 ml. soup would not be too unusual if has 0.68 grams of salt as seasoning (the same proportion) , and would not be detrimental to health. Is it because other harmful salts in the seawater or there is something else am missing ?

Sterile seawater left at total rest for a looong period of time in a tall sealed container with no air; would it have more ions concentration near the surface or near the bottom ? I mean sterile to denote no influence of movement by microorganisms of any kind to affect the 'at rest status'

This is neeeat... look at the streamers There is many more related videos, just picked one. Filled with controversy, many arguments, they built this one to prove/disprove. I like the "It may work in practice, but won't work in theory"
