Earth Ground?

           Well, it seems about time to add to my list of electrical theory questions with answers far too broad for one question, so:                          I understand that the Earth can act as a giant capacitor, conductor, etc.  What I don't understand is why.  For instance, why would ac power from the hot wire dissipate into the ground?  (and, for that matter, will power from the neutral wire not do so?  If so, why?)

Happy Earth Day!

Happy Earth Day everyone. As the Earth Days keep on coming on I see it as the one day where everyone pretends to care about green issues and then go back their regularly scheduled polluting or the day that reminds us that we still have work to do. I keep changing my mind about it. So what does Earth Day mean to you?

Hi.I was wasting some time on Google Video, and I found this one.This man believe Earth (and others planets) are expanding ...According to Wikipedia, this theory is not new, and is serious. After all, if the Sun (and stars) grows, why not the "core" of planets too ?

Hitchhikers guide to.. The Earth!

So here's the idea. I've been thinking how cool it would be to do a collaboration and create a giant travel guide. But not just an ordinary travel guide, one written by all instructables members.We have enough people on this site that we could get a pretty good start on it. I think the idea would spread fairly quickly. For example, I would write a brief something or other about my state (North Carolina), and then a full length guide for Boone, the university town that I live in. I would include basic information like population, size, etc., and also where I like to eat, what kind of tourist attractions are here, why ASU beat Michigan, etc. Some one else could add to what I wrote, and someone else could add a guide for the Charlotte/Denver area, and so on. For another state/province someone would just add a new step, etc. I realize it wouldn't be an Instructable, in the strict sense, but it would be helpful nonetheless. Not to mention we could have a lot of fun with it.What do you all think? What do the Instructables staff think about something like this? (In light of the fact that this is not a step by step guide to any one thing)Let the discussion begin. =)

Timemachine in Google Earth - Concept Extention for Google Earth

Google Earth History After the Google Earth Software was published on the Internet and became a striking success, I noticed that this software made many basic features available, which were necessary for an idea I have carried around with me for a couple of years. Actually, the idea is connected to a question that many of us have asked ourselves: You are walking on 5th Avenue in New York and wondering how this street looked 20, 50 or 100 years ago. Of course you can look up photos in relevant books or magazines and obtain a certain impression of how life was at a certain point in time in this place. But wouldn’t it be great to be able to transform this impression and create a detailed picture; to be able to literally see more and truly visualize your impression? In addition to the one or two photos which can be found in old magazines or in history books, there must be other historical documentation, which can assist in creating the picture. Surely, you can look at movie documentation, but mostly the specific place that you are interested in, is only briefly shown – or not shown at all. So let us stick with the example of 5th Avenue, New York. A place which has existed for more almost 100 years in its current form; which means something to almost every person in the western world; and which has been visited by a vast number of people at least once. As tourists like to do, they photograph the places they visit to show family and friends, where they have been. It is safe to assume that 5th Avenue is one of the places on Earth, which is most incessantly photographed by a large number of people. What a pity that all these photos are brought back to their owners’ home countries, and thus spread all over the world. The final resting place of these photos is mostly a photo album, a dusty box in the attic, or - in this digital age – a hard disk or a CD-Rom. The sum of all these photos of 5th Avenue would probably form a breathtaking historical view of this street: millions of pictures documenting all small and large changes throughout decades, pictures of well-known people visiting the avenue, events which happened here, the rise and the deterioration of different buildings. This collection of documents resembles traveling back in time in a way, that nobody has ever done before. If the owners of all photos would run their pictures through a scanner or make already digitalized photos available to the general public, you would quickly obtain an unusual diversity of photo documents. Especially, you would gain a multitude of different pictures of well-known places like the implied 5th Avenue. Once more we’ll look at an example: assuming I have a color photo from September 1994 taken on the corner of 5th Avenue and 23rd Street in New York City on which you can see e.g. the Empire State Building. I scan the photo into my computer and use the appropriate import function from Google Earth. Thus, the scan of my photograph is saved on a Google server. With the 3-D view of my Google Earth program I can now head for the corner of 5th Avenue and 23rd Street. On the exact location, where I took my picture in the real world in 1994, I now save the photo in the program’s virtual space. If many other Google Earth users would do the same thing with their photos, we would slowly have a collection of pictures from 5th Avenue. All other users now have the possibility of viewing all saved photos. So, if another user saves a photo of 5th Avenue and 28th Street, all I will have to do is to virtually move five streets north and position myself behind the digitally stored picture in order to view it. Of course, we would soon have chaotic conditions if enough people upload their pictures of 5th Avenue to the Google server: One has a photo from December 1980, another person a photo from June 1982, the third a very recent photo from 2006. All these photos will be saved geographically correct in the Google Earth program, but content-wise they will not fit together at all in such a chronologically un-sorted manner. Therefore, the program Google Earth would have to contain a new function: the depiction of the fourth dimension, time. In short, before you save a picture from June 1971 in the correct virtual place in Google Earth, you will also have to set the correct time, i.e. June 1971. In reverse, for the viewer this means that he will have to select from which time in history, he wants to see photos of the chosen 3-D surroundings, before he views the pictures in the Google Earth 3-D world. So, what is it all for? Just as Wikipedia to this day has proven very impressively, that the accumulation of individual persons’ knowledge on the Internet in sum constitutes a high value of total knowledge, so this collection would form a library of historical documents. Again we will remain with the 5th Avenue example: with a sufficiently large collection of photos the viewer has the option of looking at the street from different perspectives AND from different points in time, which may even be many years apart. History has probably never bee so easy to observe. In the end maybe he sees himself taking his photo in September 1994 while somebody other shot a photo with me in the picture. Strange, isn´t it?

You can also start your flight at a specific location if you go there in Google Earth outside of the flight simulator, and then select the "start at current view" button which is above the airport selection box. The controls can be found by going to help and then clicking on keyboard shortcuts. It's a lot of fun and has pretty good resolution. The pics are of the Himalayas.

Pressure, vacuums, and the on earth equivalent?

One atm is equivalent to about 14.7 psi.  Does that mean that if one was in a perfect vacuum a vessel sporting 1 atm would need only hold the pressure of 14.7 psi?  It seems to me that in space (not a perfect vacuum) a craft would only need to hold maybe 12 psi (of course when messing with human life I would definitely allow for 150 to 200% tolerance, but in the end 24 psi still isn't very much is it.  Is there more to it than this, or are all those quotes about how hard it is to deal with a vacuum and how things must be super strong a little over blown.  Going just 11 meters under water exposes you to a little over double air pressure at sea level.  Someone in just a diving suit has been to over 60 times atmosphere and the deepest submarine dive I could find was 1083 atm at around 11000 m.  It just seems to make holding out a vacuum a little overrated.

Would a container in space maintain its temperature?

It space where there are no particles in the air (metaphorically), would a container maintain its heat.  A vacuum doesn't conduct and in theory that would remove any chance of something losing its heat energy.  And if so would the earth lose all of its heat in the even't of the sun going away.  Or would it average out all of the temperatures, which would still be very cold and would leave the earth feeling about 0 degrees Celsius.  But in theory this would allow us to use some vast heating operation to raise the temperature of a planet and maintain it for us to live on.  I know that there are some things on earth that use the heat and convert its energy to other forms therefore heat is removed from within earth, but could those be eliminated?  This is all just food for thought for people and I kinda wondered what people would say.  Its all in all just fun to learn new things.

Thermal Cooling and Heating

It is very possible and it is in use today by using Thermal Cooling and Heating from the earth. Performed by using a 6" well at least 100' deep, with thermal tubing inserted into the well carrying the liquid to be cooled/heated. Process is done by a circulating pump in the interior unit - through the coil - sending back through the well system and returning. It starts out from the main unit circ pump.......through the coils.......out to the "down tube" into the 6" well pipe, a sharp 180* turn back up the system returning to the circ pump. Such a system is used by many facilities to Air Condition or heat rooms of about 15' x 15' or so. I have even seen a system that utilized creek water as the "cooler" of the tubing on a circ pump system. That one really was cool, about 52 degrees. Have you heard of these systems or seen something like it or close?
