The ammonia system mentioned doesnt actually boil any water. The ammonia is boiled and recondensed using hot surface water and cold deep water, the ammonia acts as a working fluid for a turbine. There is a second type of OTEC that uses water as a working fluid, but the hot surface water is boiled using a low pressure boiler, and the water is recondensed using cold deep water. At no point is the nitrogen rich cold deep water boiled and evaporated in any scenario, only the nitrogen poor surface water, and only in the second OTEC method.
That phone number, 867-5309 is the main reason that everyone now uses 555-#### whenever you see a phone number n TV or in the movies. 867-5309 was a valid phone number in many localities, and people were getting tons of calls for "Jenny" I believe that the band who came out with the song was actually sued by people who were inconvenienced. 867 is still a valid prefix in many areas, but i doubt youll find anyone at 867-5309 in any of those areas, because the phone company knows better than to assign it to anyone, its now a dead number
Except, Deep ocean water comes from a high pressure, and it has a significantly higher nitrogen content than the surface water. Algae blooms will be common near the outlets because of this, and plankton feeds on algae. these plants will be like deep water upwellings that occur due to geography in places around the world, like antarctica. In places where there is a deep water upwelling life is extremely abundant. This is why the effluent could be used for aquaculture as mentioned in another post.
This cant be a sustained effect. If the sun were continuously increasing its output by.05% a decade, the sun had a total output of 1 watt ~ 1.25 million years ago. Therefore, the solar variance is not continuous, it must be cyclical. We dont know where in the cyccle we are except to know were in the upswing portion. In 10 years it may go down again. The fact that the sun is contributing to global warming should be seeen as something that points us TOWARDS restricting carbon emissions, not away from it. If global warming has multiple causes, its even more important to restrict the human controllable ones to prevent environmental change.
Where are you getting 1920 from? Check out here Either 1885 (if youre a purist) or 1913. By your numbers, this means they need to tear down the woolworth building in nyc in 10 years. I doubt that is going to happen. Secondly, your example of the one in Philly, It was torn down because of structural damage due to a fire, not due to "normal wear and tear" on the building. Barring any external events, fires, planes, etc a skyscraper should stand for a good long time. Skyscrapers are usually built with a safety factor of 5-10 depending on their height.
My grandparents farmhouse was built in 1918 using wood that was available on the land they owned. It was insulated with Vermiculite (available today in garden centers for use in potting soils) If you open up the walls, there are no 2x4's, just logs ~4" in diameter with two faces planed off and the bark still on them. Home longevity is not a matter of materials really, its a matter of maintainance. Keeep the roof from leaking, keep the walls and floors sealed from moisture, keep the house painted and siding and shingles repaired and your house will last as long as you want
(Skyscrapers have a life of 100 years before they have to be torn down because of metal fatigue.)
Give me even one example of a skyscraper that has been torn down because of metal fatigue, and not for some other reason ( disused, make way for a bigger tower, etc)
Theres a simple solution: Spam is trying to sell you something. If you cant contact the person who is selling you the thing how can you be reasonably expected to buy it? The people who sell the products through spam should be held accountable for all damages from said spam, just like somone who hires a hit man is responsible for the murder (along with the hit man of course)
Im tired of people bitching about how were not going into space anymore. These things take time people! Youre not going to have star trek tomorrow, or the next day or maybe even in 3 centuries. The first real colony in the americas was nearly 100 years after columbus first set foot here, and there was alot more reason for people to come to america then there is for us to go to space now. We need the impetus to do it, and that means running out of more natural resources. Humans are lazy, they wont change their ways unless they are absolutely forced to. Look at how the steam engine was invented: Steam power was known about for millenia before the industrual revolution (see Heros Engine) but it was finally perfected because they needed a way to pump water out of the coal mines. They needed to do that because they were using more coal, they were using more coal because the english and most of europe had run out of trees. They had run out of trees because populations had grown and they needed to wood for housing and heating. Essentially we were forced to move to another fuel source, and this fuel source required new technology to gather it. Its amazing how innovative you can be when youre faced with being inventive or freezing to death in the winter. Space travel is no different. If we have 15 billion people on the planet in 50 years, I gaurentee we will be going into space. Not to send excess population there, but to bring back resources like power and minerals. All it takes on your part is a little patience for the population pressure to start pushing us outward again.
Thqats a common misperception. If you had an appliance from 15 years ago that WASNT reliable, you certainly wouldnt still have it around, it would have been replaced 14 years ago. After an initial burn in period, when most appliances fail, appliances will last for quite a long time. In My grandparents old house they have a fridge that was bought in the mid 50's that has never been broken a day in its life. In fact it outlived my grandparents. Of course, if you make appliances too reliable, no one will ever buy another, which is what happened in this case, as the company that made those refrigerators, Philco, went out of the buisness of making fridges years ago.
Not just the britih, look at any empire that wasnt as a result of one charismatic person (Alexander, Napoleon, Hitler) and youll find that its decline is due in a large part to decadance, complacancy and a lack of innovation. Romans used the same military manuvers for 1000 years, without any improvement. Eventually the germans caught on and bbested them with better tactics.
The problem with ID systems are that the more "uncrackable" they are, the more they are trusted. The more they are trusted, the harder it is to make things right when people circumvent those ID systems. Look at DNA evidence. Im sure that some day, some murderer is going to figure out how to plant somone elses DNA on a crime scene, thus implicating the other person. DNA= Guilt in the eyes of todays courts. The safest ID system is a minmally secure one. That way, people are naturally suspicious of an ID even if it appears to be genuine. Mistrust of ID's prevents abuse more than a so called "bulletproof" ID
Earth mining techniques were designed for earth. Just like it would suck if you took a car into outer space, if you took earth mining methods into space they would suck too. Instead of thinking of gravity as a disadvantage, ways of using low gravity environments to seperate materials must be researched. For example,in a zero G environment, electrostatic seperation might be possible. Regardless, im sure there are mothods that use lack of gravity as an advantage to mining, they just need to be researched and perfected.
You also needed colonists to back it up. Columbus claimed america for spain. All of it. North and south. Those claims were only upheld where the spanish put colonists down. Occupation is 9/10ths of ownership. Not only that, but the outer space treaty of 1968 specifically prohibits any nation from owning any celestial body. Legally, china cant claim it either (assuming they are a treaty signatory). Many people claim that this treaty provision is the reason we dont have all the outer space do dads we were promised in the 60's With now danger of the russians "owning" the moon, we were safe to let NASA stagnate. Without the treaty, even if we got to the moon first, the russians can still get up there and plant a colony. Whoever owns the moon, owns the earth. Even barring nuclear weapons from space, put a mass driver on the moon, wrap a rock in some iron and put in a guidance system, and you have a method to bombard any city on earth with a nonnuclear multi-megaton payload. And theyres no radioactive fallout when a rock hits a city, so you can just pave over the crater and move right in.

They could use Gnutar, which compresses the tar

Actually, call Jenny, 867-5309
Regardless of what the article said, the post on slashdot implied that it was .05% per decade, period. Thats what I'm responding to.
Q:If you could keep any prop from the movie, what would you keep?
A:I think I would keep the precious.

Word for people worse than terrorists: liberals ( at least according to the bush admin.)
So does that mean when you BUY microsoft products youre supporting terrorism? Support free linux today!
Well thats why I use Limewire and grow my own pot, that way funds go nowhere ;-)

I know I use both of those regularly

YOu could go to "Hidden Pirate Island" AKA Hong Kong.
