I had previously looked at making two large concrete or nanomaterial monolithic or geodesic domes over cities which could protect a city from nuclear bombs.

Now Alexander Bolonkin has come up with a cheaper, technological easy and more practical approach with thin film inflatable domes. It not only would provide protection form nuclear devices it could be used to place high communication devices, windmill power and a lot of other money generating uses. The film mass covered of 1 km**2 of ground area is M1 = 2×10**6 mc = 600 tons/km**2 and film cost is $60,000/km**2.
The area of big city diameter 20 km is 314 km**2. Area of semi-spherical dome is 628 km2. The cost of Dome cover is 62.8 millions $US. We can take less the overpressure (p = 0.001atm) and decrease the cover cost in 5 – 7 times. The total cost of installation is about 30–90 million $US. Not only is it only about $153 million to protect a city it is cheaper than a geosynchronous satellite for high speed communications. Alexander Bolonkin’s website

Promising Anti-Radiation Drug Based on Carbon Nanotubes

Posted by in categories: defense, military, nanotechnology, nuclear weapons

The Defense Advanced Research Projects Agency (DARPA) gave a $540,000 grant to researchers from Rice University to do a fast-tracked 9-month study on a new anti-radiation drug based on carbon nanotubes:

“More than half of those who suffer acute radiation injury die within 30 days, not from the initial radioactive particles themselves but from the devastation they cause in the immune system, the gastrointestinal tract and other parts of the body,” said James Tour, Rice’s Chao Professor of Chemistry, director of Rice’s Carbon Nanotechnology Laboratory (CNL) and principal investigator on the grant. “Ideally, we’d like to develop a drug that can be administered within 12 hours of exposure and prevent deaths from what are currently fatal exposure doses of ionizing radiation.” […]

The new study was commissioned after preliminary tests found the drug was greater than 5,000 times more effective at reducing the effects of acute radiation injury than the most effective drugs currently available. […]

The drug is based on single-walled carbon nanotubes, hollow cylinders of pure carbon that are about as wide as a strand of DNA. To form NTH, Rice scientists coat nanotubes with two common food preservatives — the antioxidant compounds butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) — and derivatives of those compounds.

On the brink of Synthetic Life: DNA synthesis has increased twenty times to full bacteria size

Posted by in categories: biological, biotech/medical, defense, existential risks, futurism, lifeboat, military, nanotechnology

Reposted from Next Big Future which was advancednano.

A 582,970 base pair sequence of DNA has been synthesized.

It’s the first time a genome the size of a bacterium has chemically been synthesized that’s about 20 times longer than [any DNA molecule] synthesized before.

This is a huge increase in capability. It has broad implications for DNA nanotechnology and synthetic biology.

Chinese nuclear sub shows up on Google Earth?

Posted by in categories: defense, military, nuclear weapons

Increasingly, tools readily available on the Internet enable independent specialists or even members of the general public to do intelligence work that used to be the monopoly of agencies like the CIA, KGB, or MI6. Playing the role of an armchair James Bond, Hans K. Kristensen, a nuclear weapons specialist at the Federation of American Scientists (FAS) in Washington, D.C., recently drew attention to images on Google Earth of Chinese sites. Kristensen believes that the pictures shed light on China’s deployment of its second-generation of nuclear weapons systems: one appears to be a new ballistic missile submarine [see above image]; others may capture the replacement of liquid-fueled rockets with solid-fuel rockets at sites in north-central China, within range of ICBM fields in southern Russia.

Source: IEEE Spectrum. An excellent example of how open source intelligence outsmart military intelligence.

See also: Nuclear terrorism: the new day after from the Bulletin of Atomic Scientists. From the article:

Finally, there is the question of whether the U.S. government would behave with rational restraint. This, of course, assumes that there is a government. A terrorist nuclear attack on Washington could easily kill the president, vice president, much of Congress and the Supreme Court. But in a July 12 Washington Post op-ed, Norman Ornstein revealed that the federal government has refused to make contingency plans for its own nuclear decapitation, which means that U.S. nuclear weapons could be in the hands of small, enraged launch control teams with no clear line of authority above them. Assuming that the federal government was still there, however, we can only imagine (using the reaction to the loss of a mere two buildings on 9/11 as a metric of comparison) the public rage at the loss of a city and the intense, perhaps irresistible, pressure on the president to make someone, somewhere pay for this atrocity.

The Missile Shield and the Race for Space Awareness

Posted by in categories: defense, existential risks, geopolitics, military, nuclear weapons, open source, space

The US-led effort to expand the military BMEWS (ballistic missile early warning radar system) to Poland and the Czech Republic provoke Russian military strategists. Putin has proposed using their already operative radar base in Azerbajian (See “Azeri radar eyed for US shield”, BBC) in exchange for information from the US system. The US/NATO proposed TMD (theater missile defense) will also integrate early warning systems for short-range missiles in southern Europe. Is the race for space awareness and the weaponization of space inevitable?

The justification for the missile shield is the potential threat of long range missiles from Iran and North Korea (See “N-Korea test fires missile”, BBC). Military experts predict that with the current progress of nuclear research and missile technology available to Iran they will pose a threat to the US in 2015. NATO and Russia co-operate in certain military matters through the Russia-Nato Council but has increasingly been in conflict over the Iranian nuclear program and the European missile shield. (See “Russia-NATO: A marriage of convenience”, RIA Novosti). Russia has also demonstrated the ineffectiveness of the missile shield by launching their RS-24 multiple missile system carrying 10 warheads (See “RS-24 Missiles to replace old systems within next few years”, Interfax).

Terrestrial radars need to be complemented by satellites to keep track of missile launches across the planet (so called “boost phase interceptors”, see “Missile defense, satellites and politics”, The Space Review) to ensure complete space awareness. The Chinese Space Agency tested an anti-satellite missile earlier this year (See “Pentagon says China’s anti-satellite test posed a threat to nations”, AP). The move towards a hot space war could be imminent. The official press release was the only information given from Chinese authorities. The secrecy surrounding space capabilities was recently challenged by French authorities when they discovered 20–30 unregistered US surveillance satellites. (See “French says ‘non’ to U.S. Disclosure of Secret Satellites”, Space.com).

More advice on best actions to survive a nearby nuclear blast

Posted by in categories: existential risks, military, nuclear weapons

Carnegie Mellon researchers Keith Florig and Baruch Fischhoff offer simple, practical advice: on whether it is worth citizens’ time to stock supplies needed for a home shelter, how urgently should one seek shelter following a nearby nuclear detonation, and how long should survivors remain in a shelter after the radioactive dust settles.


“A number of emergency-management organizations recommend that people stock their homes with a couple dozen categories of emergency supplies,” said Florig of Carnegie Mellon’s engineering and public policy department. “We calculated that it would cost about $240 per year for a typical family to maintain such a stock, including the value of storage space and the time needed to tend to it.”

Their research also suggests that many families who could afford to follow the stocking guidelines might think twice about whether the investment was really worth it, given the low probability that stocked supplies would actually be used in a nuclear emergency.

They advocate simple rules for minimizing risk based on how far people are from the blast. If you are within several miles of the blast, there will be no time to flee and you will have only minutes to seek shelter. If you are 10 miles [downwind] from the blast, you will have 15 to 60 minutes to find shelter, but not enough time to reliably flee the area before the fallout arrives,” said Florig.

However, the prior advice would suggest that if you are 10 miles from the blast that you could move perpendicular to the direction of the fallout plume and get out of the way in under 15 minutes. Needing to move one mile for smaller bombs. So I would think 10–20 miles downwind is a judgement call, but 25 miles you should be able to get out of the way of the fallout plume.

Missile Defense Shield Expands to Europe

Posted by in categories: defense, geopolitics, military


The Ballistic Missile Early Warning Radar System (BMEWS) at Fylingdales, U.K.

The ongoing debate on the proposed missile defense shield in Europe is heating up. Poland and the Czech Republic are among the possible sites and the UK is now showing interest in supporting the missile shield. Fears over the destabilising effects of such a shield was confirmed by a Russian general who said that they would target the system.

Vladimir Putin, Russia’s president, said America would trigger an “inevitable arms race” if it deployed interceptors in Europe to knock ballistic missiles out of the sky. A senior Russian general rumbled that Russian missiles would target any interceptors in eastern Europe. Poland’s prime minister told his people that Russia was trying to “scare” them. The Czech foreign minister (a prince with a splendid moustache) complained of Russian “blackmail”.

“The aim is to break ground on a European site in 2008, and for its interceptors to become operational in 2012. This week the Polish and Czech prime ministers said they were keen on hosting the missile-defence sites. That is a change: talks with the Poles have dragged on for years, thanks to elaborate Polish demands for things such as extra missile defences for their own country. Yet both Mr Blair and his Polish rivals face objections from three sources: from Russia, from many of their own voters and from fellow European leaders.”

Space Arms Race, Here we Come!

Posted by in categories: military, space

From WIRED.com:

The revelation last week that China had slammed a medium-range ballistic missile into one of its aging satellites on January 11 and littered space with junk fragments has created its own form of political debris in Washington, D.C.

The test, which the United States military had long anticipated, has touched off debate over how the U.S. government should interpret and respond to China’s actions.

“It’s a very provocative act,” said Gregory Kulacki, a senior analyst and China expert with the Union of Concerned Scientists. However, “policy makers should respond on the basis of accurate information, not military rhetoric and propaganda.”

Militarization of Space Looming

Posted by in categories: military, space

On CNN:

WASHINGTON (CNN) — China last week successfully used a missile to destroy an orbiting satellite, U.S. government officials told CNN on Thursday, in a test that could undermine relations with the West and pose a threat to satellites important to the U.S. military.

According to a spokesman for the National Security Council, the ground-based, medium-range ballistic missile knocked an old Chinese weather satellite from its orbit about 537 miles above Earth. The missile carried a “kill vehicle” and destroyed the satellite by ramming it.
