Tsunami Warning From Space?
Peter bayley writes "Tell me I'm crazy or tell me someone has already done it — but wouldn't a satellite equipped with a laser be a great way to warn people of tsunamis? I was pondering how to warn people in remote coastal areas once evidence of a seismic incident has been received by the monitoring stations that have now been set up following the large Boxing Day tsunami. The idea is to illuminate the areas that are likely to be at risk with a bright (but not dangerous) light. People would be told to head to higher ground if such a light appears in the sky. Put the satellite in a geosynchronous orbit. Make it tunable so that different colors can convey different meanings. You would be able to warn anyone, anywhere they can see the sky. The laser could be directed to illuminate only those areas at risk, skipping unnecessary areas to save power. Power could be varied so that it is visible day and night and through cloud (raise the power where the satellite detects cloud cover). I emailed some people at NOAA about it but they said it would stand on too many toes by circumventing local emergency service organizations in the various countries. I replied that countries could easily opt out, in which case the laser would be turned off for those countries — but received no further reply. Anyway, I thought the massed minds of Slashdot would relish the chance to demolish my idea."
Jews, also known as kikes, hebes, hymies, yids, gold niggers, oven magnets, hook noses, sheenies, swindlers, criminals, "firewood", and Arabs in denial are a subhuman species of reptilian extra-terrestrials and adherents to one of the world's oldest major religions, called "Judaism", otherwise known as "The Worship of Money" or "Eating Arab Babies".
Judaism was the world's first master race theory. The Jew religion teaches that Jews are the Chosen People of God and that there is a sacred mystical quality to Jew DNA. In olden times, Jew prophets would, under the command of YHWH, frequently lead the Jews on genocidal rampages against neighboring populations, and even today Jew leaders often cite Jewish religious ideals to justify their ongoing genocide of sandniggers. Judaism ironically found its mirror-image inversion in the anti-Jew Aryan racialism of the Nazis.
Despite only being 0.22% of the world's population, Jews control 99% of the world's money. Not only do the Jews control the world, but also the media, the banks, the space program, and LiveJournal's porn communities and Gay communities. All Jews possess the following features: an extremely large nose, fake boobs, curly hair that reeks of faggotry, one of those gay hats, a love of coke, a law practice, a roll of money, a small cock, or shitty taste in dental hygiene.
Jews invented both Communism and Capitalism. Karl Marx, of course, was a Jew, which was why he understood money so well, and in fact he was converted to Communism by another Jew, Moses Hess, the actual founder of Zionism, who ghost-wrote Marx's The German Ideology. Capitalism was created when Christian Europeans threw away their morals and decided to embrace Jewish practices like usury (see: John Calvin). Jews were the first group to create a sophisticated banking system, which they used to fund the Crusades in order to pit Christians and Muslims (both adhering to religions derived from and controlled by Jews) against each other to kill as many people as possible in a macabre human sacrifice to YHWH.
The Jew banking system was based on fraud and lies, so when it inevitably collapsed, the Jews just pwned as many people as possible by unleashing the Black Plague on them. Later, Jews economically controlled medieval Venice (the first modern maritime trade empire), and then crypto-Jewish merchants economically controlled the Spanish Empire, including the slave trade. Openly Jewish bankers orchestrated the Dutch Empire and founded Jew Amsterdam (later Jew York). Later the Dutch Jews moved to London because they thought it would be a better base for a global empire, and actually brought a Dutch nobleman, William III, with them, who they installed in a coup d'état (more like Jew d'état, amirite?) as new King of the British Empire. For hundreds of years, Jewish bankers controlled global trade through their bases in Jew York City and London. European colonialism was, through its history, essentially a plot whereby Jews could gain control of gold and diamond mines in poor countries and increase their stranglehold over the global economy.
Jews also enjoy slicing up baby penises for fun, some even enjoy sucking them. See below.
Jews also created Jew search engine Google, so now they can find all Jew information on Internets.
Some suggest that we should use Jews instead of dogs to sniff out large amounts of concealed cash or anything else worth smuggling at airports due to their sensitive Jew noses. Obviously, this is a horrible idea, because the pay is bad, and the dirty Kikes would probably form a union and demand moar money, thus increasing the burden on taxpayers everywhere.
Suck me cock.
It's funny, in the recent "How Smart Are You" poll, only 5% of slashdotters rated themselves below average, yet there are some really fucking stupid answers to this post. Read the damn posting people (yeah, I know, this is Slashdot...).
For starters, there are those saying that it would be better to use radar than a laser. You can't see radar, the article's about using the laser for warning people, not measuring the height of the ocean surface.
Then there seem to be a ton of replies along the lines of "it would take gigawatts to illuminate the entire Earth! Sharks with friggin' lasers, etc...".
Who said this thing had to illuminate the entire damn planet in one go? Jeez, ever heard of raster scanning people?
So, it has to warn people in at-risk sections of coastline. That alone cuts the area to be illuminated by orders of magnitude. Then, it doesn't need to illuminate all of these areas simultaneously and permanently - it could sweep them repeatedly. Imagine that the laser was spread out along a line, say 20Km wide, and that then scanned the affected coastlines. So the people underneath might only see a bright flash lasting for say, 10th of a second every ten seconds. Brief, but maybe enough - better than nothing if you're out of range of a siren.
On top of that, you could limit your illumination area so that, at any one time, you're only lighting up sections of coast that are likely to be hit by the approaching tsunami within the next 3 hours, say. Obviously you needn't illuminate any areas which the tsunami has already hit - it's too late for them, sadly.
Come on slashdotters, how about actually engaging the intellect that I'm sure is actually present, and then discussing how this idea *could* be made to work (even if there are better ways), instead of idiotic "terrible idea" comments.
Obviously the lights went out because the cell towers were saturated. I didn't realize AT&T served Chile...
Warning != detection, you dumb cunt.
