Alcoholism runs in my family, and I did not have children because of the possibility of them being alcoholic. I sympathize with you, except that I believe legally denying human rights is a dangerous president that may lead to worse things, for example the Holocaust.

Sorry, I am a bit dyslexic and sometimes misunderstand.

There are at least three possibilities: 1. insulator 2. insulator and heat-sink 3. insulator and peltier plate (see: http://en.wikipedia.org/wiki/Peltier_plate#Peltier_cooling_plates) The insulator and heat-sink would be best, unless you really really need to cool the hot spot well below ambient air temp. The heat sink could be as simple as a copper or aluminum surface on top of an insulator. For example, use a ceramic square (e.g., ceramic floor tile) on bottom. Place an aluminum pan on the insulator Put your thing inside the aluminum pan. The heat will be transferred into the air by the aluminum pan--most of it. The insulator will keep the surface below cool enough to prevent damage, unless it is extremely sensitive to heat. A peltier plate is cool on one side and hot on the other and uses electricity. Thus, it is a bit expensive.

So, resistance will dampen transients assuming DC.

No need to post twice.

I has already been done. The formulas are on wikipedia. Start with Sir Issac Newton.

True "Mankind has a long and impressive history of improving crop yields." But, that does not mean crop yields are improving everywhere. And, there are other things that are probably more likely than humanity running out of food. Although, there is enough food in the world today to feed everyone, some people starve because they do not have access to food in far away places or they cannot afford food that is nearby. For example, bush food, especially monkeys and apes killed for food, is a possible reason we have an HIV epidemic. Closer to home, most the US aquifers are being pumped dry (see: http://ga.water.usgs.gov/edu/gwdepletion.html), which is one reason a global surplus of food exists--the midwest is called the bread basket of the world. Better seeds cannot compensate for no water, and water resources in many parts of the world are in danger. Glaciers are disappearing around the world, and they are responsible for feeding most of the really big river systems. Past successes are no guarantee for future success. Each generation has its own unique challenges. Consider the history of Bison in the US. Before 1492, they estimate 60,000,000 lived, and by 1890 only 750 remained. Many people had to change they way they lived. Change is inevitable, and if we do not plan for it, we will suffer.

Copper is not a super conductor. A light bulb has some resistance in addition to the wire.

Does your definition of religion vs superstition include the beliefs of the ancient Greeks, Egyptians, Romans, etc., who believed in many gods, or do you consider their religion as merely superstitions. Does your definition of religion include modern wicca and Amazonian witch-doctors, or only religions recognized by the US government? Is it superstition or religion to believe in ghosts, goblins, ghouls, sprites, fairies, elves, brownies, gnomes, genies, bogies, enchanters, fays, gremlins, hobs, imps, leprechauns, mermaids, nisses, nymphs, pixies, pucks, sirens, spirits, sylphs, UFOs, bigfoot. etc. I think the line between superstition and religion is difficult to pin down, because one mans religion is another mans superstition. Both superstition and religion depend on belief in something that cannot be seen and touched by you and I at the same time. Except for venting, this has almost certainly been a waste of time, because no one will change their mind. Normally, I just live and let live.

I believe it is not right to bring children into this world who are guaranteed to suffer. I believe in individual rights, and people have the right to procreate. I believe evolution created a need in people to procreate that can make people do crazy things. Thus, this discussion will have little or no affect on the way people exercise their right to procreate. A law to put people in prison for having such a child would be insane, because the parents would escape the responsibility of rearing that child and the government would be responsible. Evolution works as beings do things that are both good and bad for themselves. In other words, even if we try to save the weak, stupidity is sometimes fatal, and the strong tend to survive.

Standing waves would imply AC current. The OP did not specify either AC or DC. Assuming DC, there would be transients initially, but no standing waves.

If someone makes a room temperature superconductor, I will willingly print this statement out and eat my words. And, I won't waffle over the inefficient process of putting energy into and taking energy out of it. It will be at least as remarkable as the nearly-weightless metal, and important to both industry and science.

I agree. I think the solar wind that streams from the sun and hits the earth to make aurora is more or less an ionized cloud between the sun and earth.

String Theory cannot be tested, which means it is a hypothesis. I am afraid the word is now "officially" ambiguous.

According to wikipedia, "According to the Planck mission team, and based on the standard model of cosmology, the total mass–energy of the universe contains 4.9% ordinary matter, 26.8% dark matter and 68.3% dark energy." See: http://en.wikipedia.org/wiki/Dark_energy Ordinary and dark matter contribute gravity to our Universe, which tend to decelerate the expansion of matter. Dark energy causes and accelerating force on matter in opposition to gravity. Little more is know about DE and DM.

Now that you have a hypothesis and assumptions, the easy part, you have to build one, the hard part.

I have already provided one link that says the sea is rising. Consequently, beaches everywhere are being covered by the sea. Unless Tuvalu is rising from the sea, it must be diminishing is area. The only pictures I know of are taken by Tuvalu residents, which some would question as not being objective. However, Wikipedia has this to say, "The 2011 report of the Pacific Climate Change Science Program published by the Australian Government, concludes: 'The sea-level rise near Tuvalu measured by satellite altimeters since 1993 is about 5 mm per year.'" See: https://en.wikipedia.org/wiki/Tuvalu#The_effects_of_climate_change.2C_El_Ni.C3.B1o_and_La_Ni.C3.B1a Tuvalu pics: http://www.tuvaluislands.com/

Recursive and iterative loops are a bit different. While, do, for, perform, etc. are iterative. An example recursive loop follows: factorial(n) = if (n==0) return(1) else return( factorial(n-1) * n); I think that is correct, I hate to release code without testing it. Recursion works because the function call (e.g., factorial) pushes its argument onto a stack, and return pops the stack. Thus, a recursive loop uses additional memory during each function call, and it is possible to exhaust available memory causing premature termination (an error). Iterative loops require a counter, which has a limited capability to store the iteration value; a condition that also causes an error when the iteration value exceeds limits. I am no expert, but AFAIK the brain does not use either iteration or recursion, except when doing an algorithm mentally. When following an iterative loop, most people are forced to keep track of an iterator and other data on paper or otherwise external to their brain. Similarly, mentally calculating a recursive algorithm generally requires careful book keeping.

It is easy to learn about Buddhism as there are many on-line resources, including forums. Of course, many Buddhists have spiritual-religious beliefs. The current Dalai Lama said, “My religion is very simple. My religion is kindness," and the quote in my sig. below. I am not a spiritual or religious man, but I admire both Gandhi and Tenzin Gyatso.

You are only a looser if you think you are. A smile, even if it is fake, makes you happier.

The OP did not specify wire size or AC.

Very few places on earth are sinking, mainly at subduction zones. However, due to melting glaciers the ocean has risen, and it is submerging beaches around the world, including beaches of Tuvalu. The effect is not yet great, but it is measurable. See: http://oceanservice.noaa.gov/facts/sealevel.html

Anything big enough to see that is said to be 100% efficient is inevitably untrue.

The speed depends a bit, wikipedia says, "Propagation speed is affected by insulation, so that in an unshielded copper conductor ranges 95 to 97% that of the speed of light." If the 900,000 km is not a straight line, the speed would probably be less. http://en.wikipedia.org/wiki/Speed_of_electricity
