Would an Arc Flash from an Industrial electrical box be hotter than the sun?

Yes. Electric arcs have a higher temperature than the surface of the Sun. But they do not have a higher temperature than the core of the Sun and they do not have as much heat as the Sun.

An electric INCANDSCENT bulb uses a tungstene filament (twisted wire) that is heated by the current passing through to several hundred degrees.  It is this heat that heats the glass.  It is also the proof of inefficiency of the bulb, because it is transforming 80% of the energy it receives into heat, giving only 20% for light!\nIn the FLUORESCENT tubes, the light is produced by the ionisation of the internal gas (neon or argon).  This ionisation is initiated by heating two small filaments at teach end of the tube, that heat up a small drop of mercury.  Once the mercury is vaporised inside the tube, the "starter" opens, creating a high voltage puls across the whole tube, ionising the gas that then becomes conductor: a small current passes through the gas, and the filaments are disconnected.  Since the ionised and conductive gas has nearly no resistance, the current is limited by the "ballast" (an inductor inserted in series).\nSince the CURRENT is limited, there is no "Joule Effect" (heating) and the tube stays pretty cool.\nTheir efficiency is about 100 times more than a bulb... (in terms of power/light ratio).

The sun is about 15 million degrees C. at its core and about 11000 degrees C. on its surface. Way too hot for anyone to get anywhere close to it.

What you are proposing violates occupational safety regulations unless you've received the proper training and permits. Keep in mind that getting an electric shock from touching charged water is extremely dangerous because water reduces the skin's resistance to electricity, especially if you have salts dissolved in it. 35 mA is 3.5 times the minimum requirement to send a heart into fibrillation. Given the high voltage and water combination, there is no question that your body's resistance would be low enough to draw the full current limit.\n\nThat said, an arc is when you create a bright plasma conducting path. Dissolving bicarb in the water will make the *water* conduct instead, and load down (short) the HV, suppressing its voltage. You'll likely just heat the water that way. Your best bet is to use distilled water. Give the electrodes sharp points to enhance the electric field near the points. Bring the electrode close enough underwater, and you'll get your arc. Note that arcs create high pressure, and the water may splash out of the container and electrocute you.

dry air conducts static electricity better, and a spark might case a fire???\n\ni know that was the case in old flower mills

Thats because it it Internet Explorer, use Firefox and it wont happen. If lightning struck your power source there would be a lot more trouble than web pages.

You might want to consider using a double wall, with air in between the inner and outer wall. If I remember correctly, air is a very poor heat conductor. Of course, like someone suggested, vacuum would be better, but that's a bit of a stretch. Air would probably work almost as good. The walls should be made out of thermo-insulants (ebonite, I believe)  and/or high heat capacity materials. Covering the outside of the box in aluminium foil would help, if the heat was generated by a source of light (like the sun), but would useless if the heat came from somehwere else. Likewise, painting the box in black would help the water inside stay warm. Covering the inside of the box  with aluminium is as useless as having knees on a fish. Unless you decide you want a lightbulb in the box, for whatever purpose, I'd say it's a waste of time and materials.

Yes because sometimes lighting can get through the electric lines and damage your PC if the building does not have proper "earthing".  Safer still, after turning off the computer, remove the plug from the socket too. Replug only after the storm has gone

solar rays could do that

Depends on what you are speaking of exactly, but there are several generalways to prevent sparks or arcing.  Make sure all connections are tight and clean, capacitors can be used across a power supply or switch to absorrb this energy, chocke coils can be useed in series with the circuit, and there are also many other more technical or invasive ways to help with this problem.  Sorry I can't help more, but would need more info to give more spacific advise.

probably not.  Unless the sun explodes

No it is not possible at this time and I doubt anyone will ever attempt it for a couple of reasons.  From NASA's webpage you can read the rest by clicking on my sources link\n\n1. Most of the power in lightning is dissipated as thunder and light, which cannot be easily harnessed to generate electric power.\n2. However, even just the electrical current of lightning is considerable -- 20,000 amps on average, the same as 100 steel welders. But the power is on for only a brief fraction of a second, so the total power is actually small, only enough to power a 100-watt light bulb for six months.\n3. The huge surge of electrical current over very brief times makes storing the energy impractical.\n4. Lightning strikes to specific locations are infrequent and inconsistent. This makes scheduling power availability impractical.\n5. Lightning can be very damaging. The collection systems have to be incredibly robust, which would drive up costs. Lightning is also very dangerous, making it tough on the collection system workers.\n6. Lightning would have to be collected over a huge area, making the system impractically expensive.\n\n#3 Its saying that lightning comes with an extreme burst of energy in a very short amount of time.  When it comes to electricity it takes awhile to build up, electricity created by a damn for example is created by the water and the turbines, it builds up slowly and is put into its reserve where ppl then draw from it.  If there was to be a massive spike were the water all of a sudden speed up to even 100mph the turbines would overheat and become useless.  Imagine charging a battery, instead of putting it on a charger and gradually letting it build up you just zapped it with a tazer or something.  Its not going to charge its going to explode.  Therefore it is impractical to store it becuase we have nothing that could take such a massive amount of energy in such a short time

You can, but there is a danger of overheating and fire. Here's why.\n\nThe power of a light bulb in watts is determined by the equation P=V^2/R where V = voltage and R = resistance. The higher power (higher wattage) light bulbs actually have lower resistance, so they draw more current.\n\nThat same current must pass through the wires, socket, etc. These also have resistance. The greater the current that passes through the wire, socket, etc. generates heat from the equation P = I^2 * R.  So, if the current is doubled, there is 4 times as much heat that is generated by the wires, socket, etc.\n\nSockets and wires have different ratings depending on their ability to handle high current and heat. You may have seen ceramic light sockets - they provide better heat resistance that lightweight sockets with plastic that can melt.

The sun is hotter. True Lightning does reach 28,000 Kelvins, and the suns surface is only 5,800 kelvins. But the suns core is 15,600,000 kelvins.

Through some ridiculous idea, scientists have been able to continue their ridiculous campaign to convince you that the core of the Sun is the hottest even though the Sun's halo-like  corona is 300 times hotter.  Sunspots show us an interior of the Sun that is even cooler than the surface, so how can this be if the core is supposed to be even hotter?  Well it isn't, and that's not where light is created and that's not where fusion takes place.\n\nLook into the "electric universe." Do a search for it.

Yes. It will superheat and have a violent reaction when something touches it.

templatebox.com has premade temps.... the "mini browser" you'll be working with is everything on the macromedia flash stage... u can also create flash using programs such as Swish
