Sociedades secretas...

Aqui ficam algum eBook's sobre o assunto:

A grande heresia. Este livro tem como pionto de partida as mesmas teorias que dão corpo ao livro "o coddigo Da Vinci". Como este é anterior á publicação do livro de Dan Brown, suponho que seja o original.

Este livro faz uma abordagem histórica e politica, bastante boa na minha opnião, das sociedades secretas. Cientificamente partece-me ter algumas lacunas ou imprecisões graves. Quando se refere a extraterrestres e outras coisas que tais... parece-me bastante improvável, mas mantenhamos um espirito de abertura, sem preconceitos.

Energia Geotérmica na Australia




Mais um caso de aproveitamento geotérmico, desta vez na Austrália, com resultados bastante promissores. Nós, para já, só nos Açores. Mas se procurarmos bem...

Aqui fica a noticia publicada in "http://digitaljournal.com/"





One per cent of Australia's geothermal energy can produce 26,000 years of electricity
Posted by Chris V. (cgull) in Environment

Australian scientists claim that just by harnessing one per cent of the country’s untapped geothermal underground energy they could produce 26,000 years worth of clean electricity power.Australia is the world’s biggest coal exporter and primarily uses coal power to generate nearly 77 per cent of its electricity. But recently the government wants to invest in more renewable sources. The government announced today that it will allocate A$50 million (US$43 million) to help develop new technology to convert geothermal energy into electricity. Resource Minister Martin Ferguson told Reuters: "Geothermal energy which is sometimes known as hot rocks has got a huge potential for Australia, both as a solution to climate change and in terms of national energy security." The power is generated from geothermal sources by pumping water below the ground and the water is heated by the high heat source. The hot water is converted to steam, which then drive the turbines to generate power and electricity. The earth central core (is about 9,000 degrees Fahrenheit) and the surrounding cores are very hot, but drilling to the center is impossible with current technologies. Luckily for the scientists, the geothermal sources are not far off from the grounds. Geoscience Australia, a governmental organization mapped the countries geothermal sources using the temperature recordings from oil and energy drilling firms’ recorded data from 5,722 petroleum and mineral boreholes. Some sources are located just five kilometers (three miles) from the ground. Geoscience Australia’s Anthony Budd told Reuters:
One percent of reserves would produce 26,000 years of energy supplies.Budd said “hot rocks” must be at least 150 degrees Celsius to generate electricity power and they have located a number of geothermal sources across Australia at a depth of one (0.60 miles) to five kilometers (three miles). And if they drill deeper, the temperature is even higher and can generate even more power. A report by the Australian Geothermal Energy association said that the country can produce 2,200 megawatts of power by 2020, fulfilling 40 per cent of the country’s electricity needs. The total cost for a 10 to 50 megawatts power producing plant is A$120 (US$104.52) per megawatt hour, but for a 300-megawatt power plant, it would cost A$80 (US$69.68) per megawatt hour. These costs are the lowest for any renewable energy method according to the report. The government wants to reduce the carbon emissions so it is trying to find more renewable energy options. Australia alone produces about 1.5 per cent of the world’s carbon emissions because of its high reliance on coal power. Per capita, Australia is the world’s biggest per-person polluter, nearly five times more than China. Initially the government will try different geothermal technologies to harness the power but later will determine the best one for other geothermal plants. Google and others are also working on this geothermal technology here in the U.S. Google invested $10 million in Enhanced Geothermal Systems. They estimate that by using this geothermal technology, just 2 per cent of the heat below North America could meet the current energy needs of the country.

No SWAT
by Radley Balko

This article appeared in Slate on April 6, 2006.

Sometime this spring, the Supreme Court will hand down its decision in the case of Hudson v. Michigan. At issue is whether or not police who used an illegal "no-knock" raid to enter a defendant's home can use the drugs they seized inside against the defendant at trial. To understand the importance of this case, some background is in order.
As the name indicates, a "no-knock" raid occurs when police forcibly enter a private residence without first knocking and announcing that they're the police. The tactic is appropriate in a few limited situations, such as when hostages or fugitives are involved, or where the suspect poses an immediate threat to community safety. But increasingly, this highly confrontational tactic is being used in less volatile situations, most commonly to serve routine search warrants for illegal drugs.
These raids are often launched on tips from notoriously unreliable confidential informants. Rubber-stamp judges, dicey informants, and aggressive policing have thus given rise to the countless examples of "wrong door" raids we read about in the news. In fact, there's a disturbingly long list of completely innocent people who've been killed in "wrong door" raids, including New York City worker Alberta Spruill, Boston minister Accelyne Williams, and a Mexican immigrant in Denver named Ismael Mena.
It's impossible to estimate just how many wrong-door raids occur. Police and prosecutors are notoriously inept at keeping track of their own mistakes, and victims of botched raids are often too terrified or fearful of retribution to come forward. But over the course of researching a paper for the Cato Institute on the subject, I've found close to 200 such cases over the last 15 years. And those are just the cases that have been reported.
It's bad enough when the police serve a no-knock warrant at the wrong place. But this is not regular service of a warrant. No-knock raids are typically carried out by masked, heavily armed SWAT teams using paramilitary tactics more appropriate for the battlefield than the living room. In fact, the rise in no-knock warrants over the last 25 years neatly corresponds with the rise in the number and frequency of use of SWAT teams. Eastern Kentucky University criminologist Peter Kraska, a widely cited expert on the "militarization" of domestic police departments, estimates that the number of SWAT team deployments has jumped from 3,000 a year in the early 1980s to more than 40,000 a year by the early 2000s.
In the 1995 case Wilson v. Arkansas, the Supreme Court for the first time ruled that at least in principle, the Fourth Amendment requires police to knock and announce themselves before entering a private home. In doing so, the court acknowledged the centuries-old "Castle Doctrine" from English common law, which states that a man has the right to defend his home and his family from intruders. The announcement requirement gives an innocent suspect the opportunity to persuade the police that they've targeted the wrong residence before having his home invaded. It also protects police from being targeted by innocent homeowners who have mistaken them for criminal intruders and those same homeowners from the burden of determining if the armed intruders in their home are police or criminals.
But Wilson didn't eliminate no-knocks. In the same decision, the court recognized three broad exceptions, called "exigent circumstances," to the announcement requirement. The most pertinent of these state that if police believe announcing themselves before entering would present a threat to officer safety, or if they believe a suspect is particularly likely to destroy evidence, they may enter a home without first announcing their presence.
A legal no-knock raid, then, can happen in one of two ways. Police can make the case for exigent circumstances to a judge, who then issues a no-knock warrant; or police can determine at the scene that the exigent circumstances exist and make the call for a no-knock raid on the spot. In the latter case, courts will determine after the fact if the raid was legal.
In the real world, the exigent-circumstances exceptions have been so broadly interpreted since Wilson, they've overwhelmed the rule. No-knock raids have been justified on the flimsiest of reasons, including that the suspect was a licensed, registered gun owner (NRA, take note!), or that the mere presence of indoor plumbing could be enough to trigger the "destruction of evidence" exception.
In fact, in many places the announcement requirement is now treated more like an antiquated ritual than compliance with a suspect's constitutional rights. In 1999, for example, the assistant police chief of El Monte, Calif., explained his department's preferred procedure to the Los Angeles Times: "We do bang on the door and make an announcement—'It's the police'—but it kind of runs together. If you're sitting on the couch, it would be difficult to get to the door before they knock it down."
That comment came in a story about a mistaken raid in which Mario Paz, an innocent man, was shot dead by a raiding SWAT team when he mistook them for criminal intruders and reached for a gun to defend himself.
Common sense says the El Monte official is unusual only in his forthrightness. Kraska's research shows that in most cities that have a SWAT team, the SWAT team serves the vast majority of drug warrants. The whole justification for SWAT procedures, which include serving warrants in the wee hours of the night and shock tactics like "flash bang" grenades, black masks, and overpowering weaponry, are to take a suspect by surprise. Were SWAT teams carefully observing the spirit of the announcement requirement by giving a vigorous knock, a full-throated announcement, and appropriate time for an occupant to answer, they'd be defeating the purpose of using paramilitary tactics to serve search warrants in the first place.
Since Wilson, the Supreme Court has only muddied the issue.
In the 1997 case Richards v. Wisconsin, the court appeared to be veering toward more protection for defendants, ruling Wisconsin's practice of serving all drug warrants with no-knock raids to be unconstitutional. Writing for the majority, Justice John Paul Stevens laid out a clear, eloquent defense of the Castle Doctrine: "The common law recognized that individuals should be provided the opportunity to comply with the law and to avoid the destruction of property occasioned by a forcible entry. ... These interests are not inconsequential."
But six years later, the court abandoned just that principle and adopted an entirely different standard. In U.S. v. Banks, the justices unanimously ruled that 15 to 20 seconds was an adequate wait time between police announcement and forced entry. More significant than the court's actual ruling, however, was its reasoning, summarized by Justice Souter rather concisely:
On the record here, what matters is the opportunity to get rid of cocaine, which a prudent dealer will keep near a commode or kitchen sink....
[I]t is imminent disposal, not travel time to the entrance, that governs when the police may reasonably enter.
With those two clauses, Souter effectively dismissed the common-law principle that announcement protects the innocent from an unjustified home invasion and instead instructed police to treat everyone named in a drug search warrant as if they were already guilty. What good is an announcement if police aren't required to give you sufficient time to answer the door? Under Souter's reasoning, it's difficult to understand what purpose the announcement requirement put forth in Wilson serves at all, other than offering a quaint, ceremonial homage to a time when the Fourth Amendment was more than a mere formality.
The Hudson case the court is now considering deals with illegal no-knock raids. That is, raids in which police couldn't even manage to follow the almost-perfunctory hoops they're required to jump through to get a legitimate no-knock warrant.
In Hudson, police in Michigan knocked and announced themselves, but waited just 3 to 5 seconds before breaking into the home of Booker T. Hudson. Once inside, they found a substantial amount of cocaine and charged Hudson with various drug crimes. When a trial court found the wait time insufficient to satisfy the knock-and-announce requirement, Hudson moved to have the evidence suppressed.
The case eventually reached the Michigan Supreme Court, which ruled that suppressing the evidence seized in the raid wasn't a proper remedy for police violating the knock-and-announce rule, and cited the inevitable discovery doctrine: Because police had an otherwise valid search warrant, their failure to announce was inconsequential. They would have found the drugs anyway.
But the exclusionary rule's primary purpose is to serve as a deterrent against Fourth Amendment violations. If police know that breaking a particular Fourth Amendment protection will result in the suppression of any evidence they find, there's strong incentive for them to follow the law.
Should the U.S. Supreme Court uphold the Michigan Supreme Court's ruling, the already-battered knock-and-announce requirement would formally still be law, but there would be no effective sanction for police who violate it (monetary damages against police in such cases are unheard of). Thus, there'd be even less incentive for police to follow the rule than there already is. That means more of these particularly dangerous kinds of searches, conducted mostly by SWAT teams with no prior announcement. And that means wrong-door raids on innocents, and, inevitably, more unnecessary terrorizing of those innocents, more injury, and likely more loss of life.

Google and Skype Invest in Open Source Wi-Fi Network



Google and Skype have made plans to invest funds in a company called Fon, which aims to create a worldwide network of Wi-Fi users, who share access to their hotspots.
With additional funding from venture capital firms, Index Ventures and Sequoia Capital, the Fon project is due to receive a total of about $22 million in financing.
If successful, Fon will allow customers to join a network of internet hotspots around the world, and share wireless signals with other users.
One of the main challenges facing the project could be a legal contest from Internet Service Providers, many of which prohibit users from sharing their connection outside of their own household.
Fon claims that their idea wouldn’t cause ISPs to lose any business, as all members of the network would be required to maintain their own broadband internet connection. Their plan even involves splitting some of the revenue with ISPs, meaning that it would theoretically benefit everyone in the long run.
With big financial votes of confidence from search giant, Google, and VoIP provider, Skype, it appears that Fon could pick up a great deal of support, and hopefully help users around the world gain access to the internet more easily.

Helium 3, o combustivel do futuro.


O Helium 3 é um elemento raro na terra, mas relativamente abundante na lua. Estudos permitem concluir que este elemento permite produzir grandes quantidades de energia. Embora a tecnologia seja semelhante à energia nuclear, neste caso é possivel obter a energia de forma completamente limpa e com uma rentabilidade muitas vezes superior. É incrivel a falta de atenção que este produto tem tido por parte da imprensa. Quem está a atrasar esta revolução?

LUNAR MINING
Samples collected in 1969 by Neil Armstrong during the first lunar landing showed that helium-3 concentrations in lunar soil are at least 13 parts per billion (ppb) by weight. Levels may range from 20 to 30 ppb in undisturbed soils. Quantities as small as 20 ppb may seem too trivial to consider. But at a projected value of $40,000 per ounce, 220 pounds of helium-3 would be worth about $141 million.

Because the concentration of helium-3 is extremely low, it would be necessary to process large amounts of rock and soil to isolate the material. Digging a patch of lunar surface roughly three-quarters of a square mile to a depth of about 9 ft. should yield about 220 pounds of helium-3--enough to power a city the size of Dallas or Detroit for a year.

Although considerable lunar soil would have to be processed, the mining costs would not be high by terrestrial standards. Automated machines, perhaps like those shown in the illustrations on the lead page, might perform the work. Extracting the isotope would not be particularly difficult. Heating and agitation release gases trapped in the soil. As the vapors are cooled to absolute zero, the various gases present sequentially separate out of the mix. In the final step, special membranes would separate helium-3 from ordinary helium.

The total estimated cost for fusion development, rocket development and starting lunar operations would be about $15 billion. The International Thermonuclear Reactor Project, with a current estimated cost of $10 billion for a proof-of-concept reactor, is just a small part of the necessary development of tritium-based fusion and does not include the problems of commercialization and waste disposal.

The second-generation approach to controlled fusion power involves combining deuterium and helium-3. This reaction produces a high-energy proton (positively charged hydrogen ion) and a helium-4 ion (alpha particle). The most important potential advantage of this fusion reaction for power production as well as other applications lies in its compatibility with the use of electrostatic fields to control fuel ions and the fusion protons. Protons, as positively charged particles, can be converted directly into electricity, through use of solid-state conversion materials as well as other techniques. Potential conversion efficiencies of 70 percent may be possible, as there is no need to convert proton energy to heat in order to drive turbine-powered generators. Fusion power plants operating on deuterium and helium-3 would offer lower capital and operating costs than their competitors due to less technical complexity, higher conversion efficiency,

smaller size, the absence of radioactive fuel, no air or water pollution, and only low-level radioactive waste disposal requirements. Recent estimates suggest that about $6 billion in investment capital will be required to develop and construct the first helium-3 fusion power plant. Financial breakeven at today's wholesale electricity prices (5 cents per kilowatt-hour) would occur after five 1000-megawatt plants were on line, replacing old conventional plants or meeting new demand.

NEW SPACECRAFT
Perhaps the most daunting challenge to mining the moon is designing the spacecraft to carry the hardware and crew to the lunar surface. The Apollo Saturn V spacecraft remains the benchmark for a reliable, heavy-lift moon rocket. Capable of lifting 50 tons to the moon, Saturn V's remain the largest spacecraft ever used. In the 40 years since the spacecraft's development, vast improvements in spacecraft technology have occurred. For an investment of about $5 billion it should be possible to develop a modernized Saturn capable of delivering 100-ton payloads to the lunar surface for less than $1500 per pound.

Returning to the moon would be a worthwhile pursuit even if obtaining helium-3 were the only goal. But over time the pioneering venture would pay more valuable dividends. Settlements established for helium-3 mining would branch out into other activities that support space exploration. Even with the next generation of Saturns, it will not be economical to lift the massive quantities of oxygen, water and structural materials needed to create permanent human settlements in space. We must acquire the technical skills to extract these vital materials from locally available resources. Mining the moon for helium-3 would offer a unique opportunity to acquire those resources as byproducts. Other opportunities might be possible through the sale of low-cost access to space. These additional, launch-related businesses will include providing services for government-funded lunar and planetary exploration, astronomical observatories, national defense, and long-term, on-call protection from the impacts of asteroids and comets. Space and lunar tourism also will be enabled by the existence of low-cost, highly reliable rockets.

With such tremendous business potential, the entrepreneurial private sector should support a return to the moon, this time to stay. For an investment of less than $15 billion--about the same as was required for the 1970s Trans Alaska Pipeline--private enterprise could make permanent habitation on the moon the next chapter in human history.

Quem sou eu

Sou aquele que não é: sou o pai natal, a musa de Camões, o diploma de Sócrates, o violino de Chopin. Sou tudo o qe é belo mas não existe. Assim é o mundo. Não te limites a olhar o horizonte e a contemplar a paisagem de areia vermelha que se estende sob ele. Caminha em direcção ao sol vermelho que se põe por trás das montanhas. não tardarás em encontrar a parede de cartão fixa à estrutura em madeira de um cenário grandioso, montado só para ti.
